Thank you for the support toward truly personalized, intelligent tutoring. - **2026-04-10** 📄 Our paper is live on arXiv — read the [preprint](https://arxiv.org/abs/2604.26962) for the design and ideas behind DeepTutor. - **2026-02-06** 🚀 10k stars in just 39 days! A huge thank you to our incredible community. - **2026-01-01** 🎊 Happy New Year! Join our [Discord](https://discord.gg/eRsjPgMU4t), [WeChat](https://github.com/HKUDS/DeepTutor/issues/78), or [Discussions](https://github.com/HKUDS/DeepTutor/discussions) — let's shape DeepTutor together. - **2025-12-29** 🎓 DeepTutor is officially released! ## ✨ Key Features DeepTutor is an agent-native learning workspace that connects tutoring, problem solving, quiz generation, research, visualization, and mastery practice in one extensible system. - **One runtime for every mode** — Chat, Ask Questions, Quiz, Research, Visualize, Solve, Course Study, Mastery Path, Immersive Reading, and Immersive Watching share one capability runtime and session context while keeping purpose-built loops and pipelines. - **Connected learning context** — Knowledge bases, books, Co-Writer drafts, notebooks, question banks, personas, and Memory can be reused across the workflows that support them, subject to account grants and learning policies. - **Immersive video learning** — paste a YouTube link for privacy-enhanced native playback, synchronized captions, timestamp-grounded tutoring, and resumable progress; administrators can switch playback to a self-hosted Invidious instance without rebuilding materials. - **Subagents and Partners** — from Chat, consult a live agent harness (Claude Code, Codex, Antigravity, Kimi, opencode, MiMo, Hermes, OpenClaw, or DeepSeek) or a Partner, import past conversations, and run persistent IM companions on the same brain. - **Multi-engine knowledge** — versioned RAG libraries across LlamaIndex, PageIndex, GraphRAG, LightRAG, a remote LightRAG Server, a self-hosted WeKnora knowledge base, a Tencent IMA or MarginNote 4 library, or a linked Obsidian vault, with pluggable document parsing. - **Extensible tools and skills** — built-in tools, MCP servers, CLI apps, image / video / voice generation models, and installable community skills from EduHub. - **Inspectable memory** — L1 traces, L2 surface summaries, and L3 synthesis make personalization visible and editable; the Memory Graph links L2 facts to L1 evidence and L3 synthesis to contributing surfaces. --- ## 🚀 Get Started DeepTutor ships four installation paths. They all share one runtime-home layout: private settings live in `data/user/settings/` under the directory you launch from (or under `DEEPTUTOR_HOME` / `deeptutor start --home` if you set one explicitly). For the full app, the recommended flow is **pick a runtime-home directory → install → `deeptutor init` → `deeptutor start`**. ### Content Workspace The **Content Workspace** is separate from DeepTutor's private runtime home. It is the folder agents may read and where every agent-created file, download, code run, cache, and rendered asset is placed under a turn-scoped `outputs////` directory. Settings, API keys, databases, Memory, and internal application state remain outside it. Without configuration, the content workspace is `/data/user/workspace`. Local PyPI, CLI, and source installs can select any existing readable/writable folder in **Settings → Workspace** or: ```bash deeptutor workspace show deeptutor workspace set /absolute/path/to/my-folder deeptutor workspace reset ``` Every capability can inspect the same folder through the built-in workspace tools. The model only receives relative paths such as `outputs/...`; when it uses `workspace_present`, the UI renders an authenticated, openable snapshot. The same exact relative path also works in a normal Markdown link or image. Changing the source file later does not change an already presented snapshot. Execution is read-only outside `outputs/`. Copying a generated file elsewhere in the content workspace requires an explicit **Allow once** confirmation for that exact source and destination. A system sandbox or the Docker runner enforces this boundary when available; local restricted-subprocess fallback is shown as **best effort** in Workspace settings.

Option 1 — Install From PyPI · full local Web app + CLI, no clone required

Full local Web app + CLI, no clone required. Needs **Python 3.11–3.14** and a **Node.js 20+** runtime on PATH (the packaged Next.js standalone server is spawned by `deeptutor start`). ```bash mkdir -p my-deeptutor && cd my-deeptutor pip install -U deeptutor deeptutor init # prompts for ports + LLM provider + optional embedding/search deeptutor start # starts backend + frontend; keep the terminal open ``` `deeptutor init` prompts for backend port (default `8001`), frontend port (default `3782`), LLM provider / base URL / API key / model, an optional embedding provider for Knowledge Base / RAG, and an optional search provider for Web Search. After `deeptutor start`, open the frontend URL printed in the terminal — by default [http://127.0.0.1:3782](http://127.0.0.1:3782). Press `Ctrl+C` in that terminal to stop both backend and frontend. Skipping `deeptutor init` is fine for a quick trial; the app boots with default ports and empty model settings, configure them later in **Settings → Models**.

Option 2 — Install From Source · develop against a checkout

For development against a checkout. Use **Python 3.11–3.14** and **Node.js 22 LTS** to match CI and Docker. ```bash git clone https://github.com/HKUDS/DeepTutor.git cd DeepTutor # Create a venv (macOS/Linux). Windows PowerShell: # py -3.11 -m venv .venv ; .\.venv\Scripts\Activate.ps1 python3 -m venv .venv && source .venv/bin/activate python -m pip install --upgrade pip # Install backend + frontend deps python -m pip install -e . ( cd web && npm ci --legacy-peer-deps ) deeptutor init deeptutor start --dev ``` `deeptutor start` builds the local `web/` frontend for production once and reuses it; `--dev` runs Next.js with HMR. Config layout, ports, and `Ctrl+C` match Option 1.

Conda environment (instead of venv)

```bash conda create -n deeptutor python=3.11 conda activate deeptutor python -m pip install --upgrade pip ```

Optional install extras — RAG engines / dev / partners / matrix / math-animator

```bash pip install -e ".[rag-lightrag]" # Built-in LightRAG engine (exact supported SDK) pip install -e ".[graphrag]" # Microsoft GraphRAG engine (Python 3.11–3.13) pip install -e ".[dev]" # tests/lint tools pip install -e ".[partners]" # Partner IM channel SDKs pip install -e ".[video-learning]" # compatibility extra; captions ship in the full/CLI installs pip install -e ".[matrix]" # Matrix channel without E2EE/libolm pip install -e ".[matrix-e2e]" # Matrix E2EE; requires libolm pip install -e ".[math-animator]" # Manim addon; requires LaTeX/ffmpeg/system libs ```

Frontend dependency tweaks & dev-server troubleshooting

**Changing frontend dependencies:** run `npm install --legacy-peer-deps` to refresh `web/package-lock.json`, then commit both `web/package.json` and `web/package-lock.json`. **Stuck dev server:** if `deeptutor start --dev` reports an existing frontend that isn't responding, stop the PID it prints. If no Next.js process is actually running, the lock files are stale — remove them and retry: ```bash rm -f web/.next/dev/lock web/.next/lock deeptutor start --dev ```

Option 3 — Docker · one self-contained container

One container for the full Web app. Images on GitHub Container Registry: - `ghcr.io/hkuds/deeptutor:latest` — latest stable release - `ghcr.io/hkuds/deeptutor:` — exact release without the leading `v` (for example `:1.6.3`); pre-releases receive only their version tag > See [CONTAINERIZATION.md](./CONTAINERIZATION.md) for podman/rootless/read-only-rootfs deployments and the full per-installation guide. ```bash docker run --rm --name deeptutor \ -p 127.0.0.1:3782:3782 \ -v deeptutor-data:/app/data \ ghcr.io/hkuds/deeptutor:latest ``` To choose a host content folder at container startup, mount it at the stable container path and lock DeepTutor to that path: ```bash mkdir -p "$PWD/deeptutor-workspace/outputs" docker run --rm --name deeptutor \ -p 127.0.0.1:3782:3782 \ -v deeptutor-data:/app/data \ -v "$PWD/deeptutor-workspace:/workspace" \ -e DEEPTUTOR_WORKSPACE_ROOT=/workspace \ -e DEEPTUTOR_WORKSPACE_ALLOWED_ROOTS=/workspace \ ghcr.io/hkuds/deeptutor:latest ``` For Compose, set `DEEPTUTOR_WORKSPACE_HOST=/absolute/host/folder` before running `python scripts/docker_compose.py up -d`. When omitted it uses `./data/user/workspace`. Docker paths are selected at startup and therefore appear locked in the Web settings page. > **Only `3782` needs to be published.** The browser talks exclusively to the frontend origin; the Next.js middleware (`web/proxy.ts`) forwards `/api/*` and `/ws/*` to the FastAPI backend **inside the container**. Publishing `8001` (`-p 127.0.0.1:8001:8001`) is optional — handy only for hitting the API directly with curl or scripts. Open [http://127.0.0.1:3782](http://127.0.0.1:3782). The container creates `/app/data/user/settings/*.json` on first boot; configure model providers from the Web Settings page. Config, API keys, logs, the default Content Workspace, memory, and knowledge bases persist in the `deeptutor-data` volume. A separately mounted Content Workspace persists at its host path instead. Optional extras belong on the deployment, not in a shell: set `DEEPTUTOR_EXTRAS` (and `DEEPTUTOR_APT_PACKAGES` for system libraries) and every container started from it re-applies them, where a `docker exec … pip install` would be lost at the next `compose down`. - **Different host ports:** change the left side of each `-p host:container` mapping (e.g. `-p 127.0.0.1:8088:3782`). If you change container-side ports in `/app/data/user/settings/system.json`, restart and update the right side of each mapping to match. - **Detached:** add `-d`, then `docker logs -f deeptutor` to follow, `docker stop deeptutor` to stop, `docker rm deeptutor` before reusing the name. The `deeptutor-data` volume keeps private runtime data and the default Content Workspace across restarts; a separately mounted Content Workspace persists at its host path. **Remote Docker / reverse proxy:** the browser only talks to the frontend origin (`:3782`); the in-container Next.js middleware forwards `/api/*` and `/ws/*` to the backend server-side. For the common single-container case you don't configure an API base at all — just point your reverse proxy / TLS terminator at `:3782`. You only need an API base for a **split deployment** (backend in a separate container/host): set `next_public_api_base` in `data/user/settings/system.json` to the in-network address the frontend server uses to reach the backend (it's read server-side, never sent to the browser). ```json { "next_public_api_base": "http://backend:8001" } ``` `next_public_api_base_external` (and its alias `public_api_base`) are accepted as lower-precedence fallbacks. CORS uses frontend **origins**, not API URLs. With auth disabled, DeepTutor permits normal HTTP/HTTPS browser origins by default. With auth enabled, add exact frontend origins: ```json { "cors_origins": ["https://deeptutor.example.com"] } ```

Connecting to Ollama / LM Studio / llama.cpp / vLLM / Lemonade on the host

Inside Docker, `localhost` is the container itself, not your host machine. To reach a model service running on the host, use the host gateway (recommended): ```bash docker run --rm --name deeptutor \ -p 127.0.0.1:3782:3782 -p 127.0.0.1:8001:8001 \ --add-host=host.docker.internal:host-gateway \ -v deeptutor-data:/app/data \ ghcr.io/hkuds/deeptutor:latest ``` Then in **Settings → Models**, point the provider Base URL at `host.docker.internal`: - Ollama LLM: `http://host.docker.internal:11434/v1` - Ollama embedding: `http://host.docker.internal:11434/api/embed` - LM Studio: `http://host.docker.internal:1234/v1` - llama.cpp: `http://host.docker.internal:8080/v1` - Lemonade: `http://host.docker.internal:13305/api/v1` Docker Desktop (macOS/Windows) usually resolves `host.docker.internal` without `--add-host`. On Linux, the flag is the portable way to create that hostname on modern Docker Engine. **Linux alternative — host networking:** add `--network=host` and drop the `-p` flags. The container shares the host network directly, so open [http://127.0.0.1:3782](http://127.0.0.1:3782) (or the `frontend_port` in `system.json`), and host services can be reached with normal localhost URLs like `http://127.0.0.1:11434/v1`. Note that host networking exposes container ports directly on the host and may conflict with existing services — to keep them on loopback, set `BACKEND_HOST=127.0.0.1` and `FRONTEND_HOST=127.0.0.1` (see [CONTAINERIZATION.md](./CONTAINERIZATION.md)).

Option 4 — CLI Only · no Web UI, from a source checkout

When you don't need the Web UI. The CLI-only package is installed from a source checkout, not from PyPI. ```bash git clone https://github.com/HKUDS/DeepTutor.git cd DeepTutor # Create a venv (macOS/Linux). Windows PowerShell: # py -3.11 -m venv .venv-cli ; .\.venv-cli\Scripts\Activate.ps1 python3 -m venv .venv-cli && source .venv-cli/bin/activate python -m pip install --upgrade pip python -m pip install -e ./packaging/deeptutor-cli deeptutor init --cli deeptutor chat ``` `deeptutor init --cli` shares the same `data/user/settings/` layout as the full app but skips the backend/frontend port prompts. It still offers the Embedding and Search selectors (choose **Skip** when you do not need them), writes the key runtime files (`system.json`, `auth.json`, `integrations.json`, `interface.json`, `model_catalog.json`, `main.yaml`, `agents.yaml`), and prompts for the active LLM provider and model.

Common commands

```bash deeptutor chat # interactive REPL deeptutor chat --capability deep_solve --tool rag --kb my-kb deeptutor run chat "Explain Fourier transform" deeptutor run deep_solve "Solve x^2 = 4" --tool rag --kb my-kb deeptutor kb create my-kb --doc textbook.pdf deeptutor memory show deeptutor config show ```

The local `deeptutor-cli` install ships no Web assets or server dependencies. Keep the source checkout around — the editable install points to it. To add the Web app later, install the PyPI package (Option 1) and run `deeptutor init` + `deeptutor start` from the same workspace.

Code Execution Sandbox (office skills) · running model-generated code for docx / pdf / pptx / xlsx

The built-in office skills — **docx / pdf / pptx / xlsx** — work by having the model write a short Python script (`python-docx`, `reportlab`, `openpyxl`, …), run it through the single `exec` tool, and present the saved workspace file. Those tools mount whenever a sandbox backend is active. DeepTutor selects the strongest configured backend in this order: - **Runner sidecar:** `DEEPTUTOR_SANDBOX_RUNNER_URL` routes execution to the hardened, least-privileged service from `Dockerfile.runner`. - **Linux bubblewrap:** when available, `bwrap` isolates the process and files. - **Restricted subprocess fallback:** local and single-container installs use this only when allowed; under Docker the container remains another boundary. The `sandbox_allow_subprocess` setting in `data/user/settings/system.json` (default `true`) controls only the last fallback. Set it to `false` (or export `DEEPTUTOR_SANDBOX_ALLOW_SUBPROCESS=0`) to refuse subprocess execution when no runner or `bwrap` backend is available; it does not disable those stronger backends.

Configuration reference — config files under data/user/settings/ (JSON/YAML)

Everything under `data/user/settings/` is plain JSON/YAML. The **Settings** page in the browser is the recommended editor. | File | Purpose | |:---|:---| | `model_catalog.json` | Provider connections plus LLM, task, embedding, search, TTS, STT, image, and video profiles, credentials, and active selections | | `system.json` | Backend/frontend ports, public API base, CORS, SSL verification, attachment directory and upload/extraction limits | | `auth.json` | Optional auth toggle, username, password hash, token/cookie settings | | `integrations.json` | Optional PocketBase and sidecar integration settings | | `interface.json` | UI and model output language / theme / sidebar preferences | | `content_workspace.json` | Content Workspace folder bindings and the active workspace selection | | `video_learning.json` | Default YouTube/Invidious playback provider, Invidious origins, and optional transcript adapter | | `main.yaml` | Runtime behavior defaults and path injection | | `agents.yaml` | Capability/tool temperature and token settings | Web Search references are filtered by default: only public `http`/`https` URLs without embedded credentials or unusual ports are surfaced. Deployments can add an education-focused domain policy in `data/user/settings/system.json`: ```json { "web_search_source_filtering": { "enabled": true, "blocked_domains": ["spam.example"], "trusted_domains": ["edu.cn", "arxiv.org"] } } ``` When `trusted_domains` is non-empty, references are limited to those domains and their subdomains; `blocked_domains` always takes precedence. Project-root `.env` is **not** read as an application config file. For a minimal model setup, open **Settings → Models**, add an LLM profile (Base URL / API key / model name), and save. Add an embedding profile only if you plan to use Knowledge Base / RAG features. LLM and task-model profiles expose an **API format** setting when their provider supports a choice. Keep `Auto` for normal routing and fallback, or choose `OpenAI Chat Completions`, `OpenAI Responses`, or `Anthropic Messages`; forced Responses remains fail-closed. The persisted field is `api_format` (`auto`, `openai_chat`, `openai_responses`, or `anthropic`); `wire_api` is derived compatibility state. Per-model `Auto` / `Supported` / `Not supported` overrides cover tool calling, image input, JSON output, and reasoning controls.

Uninstall and cleanup

DeepTutor separates its installed code, private runtime home, and optional Content Workspace. By default, the runtime home is the directory where you run `deeptutor init` / `deeptutor start`; `--home PATH` or `DEEPTUTOR_HOME` overrides it. Private application state is the `data` directory inside that home, so the startup banner line beginning with `Workspace:` identifies that runtime location. If **Settings → Workspace** points to another folder, back up or remove that content folder separately; it is intentionally not erased by uninstalling DeepTutor. 1. Stop the app. Press `Ctrl+C` in the terminal running `deeptutor start`, or run `deeptutor stop [--home PATH]` for a launcher started with `--detach`; stop any running Partner and detached Docker containers before deleting data. 2. Remove runtime data only if you also want to erase all local state. This includes settings and API keys, chat history, sessions, Memory, Notebooks, Books, Reading state, Skills, Partners state, logs, Knowledge Bases, parse caches, generated artifacts, and the packaged frontend runtime cache. First copy the exact `Workspace:` path from the startup banner and verify that its `data` child is the intended DeepTutor data directory. Back it up if anything may be needed later, then move that exact directory to your operating system's Trash/Recycle Bin. Do not run a recursive deletion command against a relative path or an unresolved environment variable. 3. Remove the installed package. Use the command that matches the distribution: ```bash python -m pip uninstall deeptutor python -m pip uninstall deeptutor-cli ``` If the virtual environment was created only for DeepTutor, remove it through your environment manager. For a source install, deactivate the environment, leave the source directory, and run `git status --short` inside that exact checkout. Only move the checkout to Trash/Recycle Bin after confirming it contains no unrelated or uncommitted work. 4. For the Docker path, inspect the exact container and named volume before removing them. Volume removal permanently erases the Docker-managed data: ```bash docker ps -a --filter name=^/deeptutor$ docker volume inspect deeptutor-data docker rm -f deeptutor docker volume rm deeptutor-data ```

DeepTutor home — the Chat workspace with every surface in the sidebar

🏗️ System architecture

💬 Chat — The Agent Loop You Actually Use

Chat is the default capability and where most work begins. A single thread can talk normally, call tools, ground itself in selected knowledge bases, read attachments, generate images, consult subagents, write notebook records, and continue with the same context across turns.

The loop is deliberately simple: the model thinks in rounds, calls tools when useful, observes the results, and finishes with a tool-free message. `ask_user` is special — instead of guessing, the agent can pause the turn, ask a structured clarifying question, and resume once you answer.

User-toggleable tools are `brainstorm`, `web_search`, `paper_search`, `reason`, and `geogebra_analysis` — plus `imagegen` and `videogen` once you configure the matching generation model. Contextual tools such as `rag`, `kb_files`, `read_source`, `read_memory`, `write_memory`, `read_skill`, `load_tools`, `exec`, `web_fetch`, `ask_user`, `list_notebook`, `write_note`, `question_bank`, `github`, `consult_subagent`, `workspace_list`, `workspace_read`, `workspace_search`, `workspace_present`, and `workspace_export` mount automatically when the turn has the right context. Context comes in two kinds: **sticky session context** (capability, workspace or course, tools, knowledge bases, persona, model, and Reading / Mastery state) persists across turns; **one-time references** (files, chat history, books, reading sections, notebooks, question bank, imported agents) come from the `+` menu for a single turn. The voice button only transcribes the current message. Home keeps **Chat**, **Ask Questions**, **Quiz**, and **Visualize** one click away; **Research** for cited reports, **Solve** for worked reasoning, and **Immersive Watching** sit under *More Capabilities*. **Mastery Path** and **Immersive Reading** are dedicated sidebar workspaces; Reading adds verified clickable citations, saved citations and notes, source-grounded read-aloud / study guidance / vocabulary / quiz / translation actions, and notebook capture, while Course Study keeps its own course-bound context.

🤝 Partner — Persistent Companions on the Same Brain

Partners are persistent companions with their own soul, model policy, library, memory, and channels. They are not a separate bot engine: every inbound web or IM message becomes a normal `ChatOrchestrator` turn inside a partner-scoped workspace. A partner is "a chat that has a personality and a phone number."

Each partner has a `SOUL.md`, model selection, channels, tool policy, and assigned library. Knowledge bases, skills, and notebooks are copied into `data/partners//workspace/`, so the same RAG, skill, notebook, and memory tools work without special cases. Authenticated non-admin users keep private partner sessions and relationship memory while the partner reads their personal memory read-only; admin, group, and unbound traffic use the shared partner scope.

The channel layer is schema-driven and can connect to IM platforms such as Feishu, Telegram, Slack, Discord, DingTalk, QQ/NapCat, WeCom, WhatsApp, Zulip, Mattermost, Matrix, Mochat, and Microsoft Teams depending on installed extras and configured credentials. A partner can also be connected as a subagent and consulted from a normal chat turn — see **My Agents** below. For faster setup, the Partner channel page can create a Feishu/Lark app or WeCom AI bot, or sign a personal WeChat account in, from a QR scan drawn in the browser rather than the server log. Feishu/Lark detects the account domain and saves the scanning user as the initial allowed sender. WeCom keeps an existing allowlist and otherwise defaults to all users who can reach the bot, with a visible open-access warning; the manual channel forms remain available if a provider's scan protocol changes.

🧑‍🚀 My Agents — Consult & Import Other Agents

My Agents turns other agents into context for DeepTutor, and does two distinct things. **Connect a live agent** — Claude Code, Codex, Antigravity, Kimi, opencode, MiMo Code, Hermes Agent, OpenClaw, or DeepSeek Harness on your machine, or one of your Partners — and consult it from inside a chat turn: DeepTutor actually *runs* the other agent and streams its work into the Activity panel via the `consult_subagent` tool. Select it and its round limit with the Agent chip, or filter the same connected-agent list with `@`; the choice stays attached to the session.

**Import past conversations** — bring in your existing Claude Code and Codex history as named, searchable, resumable agents. Choose Claude history by project / working directory and Codex history by calendar date; refresh re-syncs that scope and pulls in new conversations. Reference one from a Chat turn via `+` → My Agents, and DeepTutor reads it as a third-party transcript — it stays *their* conversation, not DeepTutor's own voice.

✍️ Co-Writer — Selection-Aware Markdown Drafting

Co-Writer is a split-view Markdown workspace for reports, tutorials, notes, and long-form learning artifacts. Documents autosave and render a live preview (KaTeX math, diagram fences), and can be saved back into notebooks when a draft becomes reusable context. Import a `.docx` to start a new draft, and export the current editor as Markdown or Word.

Its defining idea is **surgical editing**: select a span and ask DeepTutor to rewrite, expand, or shorten it. The edit agent can ground the change in a knowledge base or web evidence and keeps a trace of its tool calls. If the draft has not changed while it works, the result replaces the selected text directly and remains reversible with **Undo**.

📖 Book — Living Books from Your Materials

Book turns selected sources into an interactive **living book** — not a static PDF, but a reading environment built from typed blocks. A book can start from knowledge bases, notebooks, question banks, or chat history; the creation flow proposes a chapter outline before content is generated, so you review the shape instead of accepting a blind one-shot output.

Book quiz block Book Manim animation block Book interactive widget block

Each chapter compiles into editable typed blocks — text, callouts, quizzes, flash cards, timelines, code, figures, interactive HTML, animations, concept graphs, deep dives, and user notes — with its own Page Chat. Insert, move, regenerate, rewrite, or switch a block type; selected passages enter a reviewable learning-capture inbox. Progress, bookmarks, quiz attempts, captures, and Page Chat stay private per reader even when an admin book is shared read-only or for collaborative editing; shared deletion stays admin-only. Any book exports to Markdown, long compiles pause and resume, and `deeptutor book health` / `refresh-fingerprints` flag source drift.

📚 Knowledge Center — Multi-Engine RAG Libraries

Knowledge bases are the document collections behind RAG — they ground Chat turns, Co-Writer edits, Book generation, and Partner conversations. What's distinctive is a **choice of retrieval engines**: **LlamaIndex** (the default, hybrid vector + BM25 with optional cross-encoder reranking and exact-flat or HNSW FAISS indexes), **PageIndex** (reasoning retrieval with page-level citations, hosted or self-hosted OSS), **GraphRAG** and **LightRAG** (knowledge-graph retrieval), **LightRAG Server** (retrieval offloaded to an external LightRAG instance you connect over HTTP), **WeKnora** (retrieval from a knowledge base in your self-hosted deployment, without a local index or document copy), **Tencent IMA** (a library you curate in IMA — searched, browsed, and written back to over its OpenAPI), **MarginNote 4** (your MN4 study data — documents, excerpts, mind-map cards and the links between them — pushed in by the app's Add-on and navigated with dedicated tools), or a linked **Obsidian** vault the tutor reads and writes in place. Each KB is bound to one engine.

Migrating an existing Obsidian, Hermes, or Markdown library? See [Knowledge migration guide](KNOWLEDGE_MIGRATION.md) for connected-vault and indexed-copy paths. Creating a KB, you either **create new** (upload documents and build a fresh index) or **link existing** (reuse an index built elsewhere, read in place with no re-index). A KB can also track **GitHub repositories** (repo, branch, glob) or **documentation-site URLs** (bounded crawl depth and page count); on-demand sync hash-diffs added, changed, and removed content so followed documentation stays current without re-uploading. Re-indexing writes a new flat `version-N` directory and keeps prior ones, so a working index is never destroyed mid-rebuild. A single document can be removed even from an **error**-state base — dropping a file that failed to parse without a full delete-and-rebuild. Document parsing — Text-only, MinerU, Docling, Tika, markitdown, PyMuPDF4LLM, or LiteParse — is chosen in **Settings → Knowledge Base**, with local model downloads off by default. Docling can also run in **remote** mode against a Docling Serve server (no local install or models needed), configured via **Settings → Document Parsing** (`mode=remote`, a server base URL, and an optional API key) or the `DOCLING_MODE` / `DOCLING_API_BASE_URL` / `DOCLING_API_TOKEN` environment variables. Tika is remote-only and points at the Apache Tika server configured on that page. The CLI mirrors the lifecycle with `list/info/create/add/search/set-default/delete`, source add/remove commands, `list-sources`, and `sync`. The built-in LightRAG engine is installed with `pip install 'deeptutor[rag-lightrag]'`. That extra contains the supported LightRAG SDK but does not install MinerU. Choose MinerU independently in Document Parsing and either configure its cloud mode or install its current local CLI when structured parsing is wanted. MinerU accepts PDF, common raster images, DOCX, PPTX, and XLSX; the legacy `magic-pdf` command remains PDF-only. Text-only and the other parsing engines do not require MinerU.

🌐 Learning Space — Skills, Personas, and Reusable Context

Learning Space is the library, organization, and personalization layer. **Conversations & Materials** holds Chat History, notebooks — with records that move or copy between notebooks and a Markdown export — and a question bank that keeps your answer, reference answer, and explanation. **Personalization** holds personas, skills (`SKILL.md` playbooks), one-click **MCP Services**, and **CLI Apps** from the [CLI-Anything](https://github.com/HKUDS/CLI-Anything) catalog, each with an on-demand usage guide. The separate **My Courses** workspace groups subject conversations and tutor threads; each asset is offered only in the workflows that support it.

You don't have to write every skill yourself — **Import from EduHub** browses the community catalog and downloads a skill straight into your library through a security gate (see [Ecosystem](#-ecosystem--eduhub--the-skills-community)).

🧠 Memory — Inspectable Personalization

Memory is a file-backed, three-layer system you can read, curate, and audit — deliberately *not* a hidden vector store. **L1** is the workspace mirror plus an append-only event trace (`trace//.jsonl`); **L2** is per-surface curated facts (`L2/.md`) with references to L1 entities; **L3** is cross-surface synthesis (`L3/.md`) that records its contributing L2 surfaces.

The Memory Graph shows the whole pyramid — L3 synthesis at the centre, L2 in the middle ring, L1 traces on the outside — with exact L2 → L1 evidence edges and L3 → contributing-surface links. Memory is tracked across `chat`, `notebook`, `quiz`, `kb`, `book`, partner, and `cowriter` surfaces; the consolidator's Update / Audit / Dedup budgets are tuned in **Settings → Memory**.

⚙️ Settings — One Control Plane

Settings is the operational control plane, opening on a live status strip (backend health and resident memory), the interface and model output language, and a **Readiness** matrix grading every capability as blocker, warning, or suggestion — then a persistent, searchable navigator that reaches any page in one click: **Appearance** (theme, code-block styling), **Network** (API base, ports, CORS), **Workspace** (the agent-readable folder and its shared `outputs/`), **Models** (Connections, LLM, Task models, Embedding, Search, Text-to-Speech, Speech-to-Text, Image Generation, Video Generation), **Knowledge Base** (document parsing engine), **Chat** (Video Learning, searchable tools, per-capability parameters, starting points, attachment caps), **Partners & Agents** (nine local harnesses), **Learner profile** (age, grade, curriculum, language, reading level, explanation style), **Guardian** (authorized learners, materials, reports, credential resets), **Memory** (the consolidator's budgets), and **About** (version checks and safe updates). A **connection** holds one vendor credential and mirrors it into every service that vendor can serve, so a key is entered once rather than pasted into five pages; **task models** pin a small, fast model for the work nobody asked for — naming a conversation, writing the composer's starting points — and resolve to the active default when left empty. **Video Learning** under Settings → Chat defaults to the official privacy-enhanced YouTube IFrame Player. To keep playback local, set the administrator-managed Invidious API origin (for example `http://127.0.0.1:3000`), test it, select Invidious, and save. New or reopened videos pick up the provider immediately with the same material ID and progress. Invidious media is streamed through DeepTutor's byte-range proxy; upstream URLs are neither exposed to the browser nor stored on disk. If the instance fails, DeepTutor stays offline from YouTube until the learner explicitly chooses the native YouTube fallback. Public-caption tutoring is optional: install `.[video-learning]`; playback continues without it, while transcript-based **Explain here** is disabled with a reason.

DeepTutor appearance settings and themes

Most sections use a draft-and-apply flow, so you can test a provider before committing it. You can also just ask in Chat: the assistant reads the current configuration, applies a change, and says whether it needs a restart or a re-index — probing a new model before it commits, so it cannot switch itself onto something unreachable. API keys never pass through the model, which opens the matching form for you instead. Four themes ship in the box — Default, Cream, Dark, and Glass. Project-root `.env` files are intentionally ignored; runtime configuration lives under `data/user/settings/*.json` unless `DEEPTUTOR_HOME` or `deeptutor start --home` points the app elsewhere. **OpenAI Codex OAuth (experimental).** Picking **OpenAI Codex** under Models → LLM replaces the API-key fields with a browser sign-in that runs against your own ChatGPT plan, so no `OPENAI_API_KEY` is needed. Tokens live only in `data/system/user-secrets//private/openai-codex/` — in the multi-container Compose deployment, outside every tree the exec sandbox can reach — and DeepTutor never reads or modifies your `~/.codex` CLI login. The model list comes from that account's live catalog; signing in publishes the profile but only becomes the active model when no LLM is configured yet. Because a token authorizes one person's plan, the profile is not shareable through user grants — each account signs in for itself, ordinary users included: their card sits under Models → LLM, and the resulting models, catalog, and sign-out stay private to that account. Default local Docker and Podman deployments use separate loopback networks and need a temporary bridge during sign-in. Follow the [temporary local Codex OAuth bridge guide](./CONTAINERIZATION.md#temporary-local-codex-oauth-bridge) for the exact Docker, Compose, Podman, and teardown commands. For a remote deployment, the browser's `localhost` and the server's `localhost` are different machines, so an ordinary reverse proxy alone cannot carry the browser's localhost callback to the server. Use an SSH tunnel as the callback bridge. The tunnel reaches the already-published Web port; Next.js rewrites only the exact callback path to the public callback broker, and the broker validates `state` before routing to the original OAuth operation. The callback listener remains on the backend loopback, ports `1455` and `1457` are not published, and this path supports the default Docker bridge network. ```bash ssh -N -L 1455:127.0.0.1:3782 @ ``` If DeepTutor reports fallback callback port `1457`, use: ```bash ssh -N -L 1457:127.0.0.1:3782 @ ``` Run only the one command that matches the actual callback port; never run both. `3782` is only the example Web port: it is the configured frontend/container port reported as `callback_forward_port`. That value does not guarantee that the same port is listening on the SSH host's `127.0.0.1`. If Docker or Podman publishes a different host port, or a reverse proxy listens on a different port, replace only the right-hand target port (`3782` above) with the Web port actually listening on the SSH host's `127.0.0.1`; keep the left-hand callback port as `1455` or `1457`. `` is the SSH host whose loopback owns that listening port. If the browser URL names a reverse proxy or load balancer, replace it with the correct SSH frontend host. The CLI prints the tunnel command and then immediately tries to open the browser. On a remote deployment, keep the authorization page open without completing it, establish the printed tunnel in another terminal, and only then continue authorization. Remote-topology detection has a localhost boundary. If Web itself is reached through an SSH or IDE localhost forward, the browser cannot tell that the server is remote. For the current Web operation, leave its authorization page unfinished, read `redirect_uri` in that operation's authorize URL to identify callback port `1455` or `1457`, and create the second tunnel from that local port to the actual Web port. Alternatively, cancel that Web operation and start a new one with the CLI; the CLI output belongs to the new operation and must not be used for the existing Web operation. Quota errors and catalog failures are reported as-is and never fall back to a paid provider. This compatibility path is experimental: the upstream interface may change.

👥 Multi-User — Shared Deployments · optional auth, isolated per-user workspaces

Authentication is **off by default** — DeepTutor runs single-user. Turn it on and one `data/` tree hosts an admin workspace, isolated per-user workspaces, and partner workspaces side by side: ```text data/ ├── user/ # Admin workspace + global settings ├── users// # Per-user scope: chat history, memory, notebooks, KBs ├── partners//workspace/ # Partner (synthetic-user) scope ├── cli-apps/ # Installed CLI apps, mounted read-only into the sandbox └── system/ # auth · grants · audit · user-secrets/ (OAuth tokens) ``` The **first registered user becomes admin** and owns model catalogs, provider credentials, shared knowledge bases, skills, canonical shared books, and per-user grants. Admin-created local users choose Standard, Learner, or Custom. Learner locks learning capabilities and material policy, adds an adaptive profile, and supports revocable device credentials with expiry and daily limits; authorized guardians can view reports, approve materials, and reset credentials. Other users get isolated workspaces plus scoped models, KBs, skills, partners, and shared-book access without receiving raw API keys. If `auth.json` already carries a `username` + `password_hash`, that account *is* the admin: `/register` stays closed and accounts created from `/admin/users` are always `role=user` until you promote them. **Enable it:** turn auth on in `data/user/settings/auth.json`, restart `deeptutor start`, register the first admin at `/register`, then add users from `/admin/users` and assign models, KBs, skills, partners, tool/MCP/CLI-app policy, and code-execution access through grants; configure shared books under each user's **Book access** panel. > PocketBase stays a single-user integration — keep `integrations.pocketbase_url` blank for multi-user deployments unless you've wired up an external user store.

## ⌨️ DeepTutor CLI — Agent-Native Interface One `deeptutor` binary, two ways in: an interactive **REPL** for people who live in the terminal, and structured **JSON** for other agents that drive DeepTutor as a tool. Same capabilities, tools, and knowledge bases either way.

Drive it yourself

`deeptutor chat` opens an interactive REPL and selects a mode with `--capability`; `deeptutor run ""` takes that capability as its first positional argument and exits after one turn. Both accept `--tool`, `--kb`, and `--config`. ```bash deeptutor chat # interactive REPL deeptutor chat --capability deep_solve --kb my-kb --tool rag deeptutor run chat "Explain the Fourier transform" --tool rag --kb textbook deeptutor run deep_research "Survey 2026 papers on RAG" \ --config mode=report --config depth=standard ``` Core workspace management is here too — knowledge bases (`kb`), sessions (`session`), partners (`partner`), skills (`skill`), notebooks, memory, and config; course and session organization remain in the Web app. Full list below.

Let an agent drive it

DeepTutor is built to be *operated by another agent*. Add `--format json` to any `run` and each turn streams **NDJSON — one event per line** (`content`, `tool_call`, `tool_result`, `done`, …), every line tagged with its `session_id`. Runs are headless-safe: an `ask_user` pause with no TTY auto-resolves with an empty reply instead of hanging. ```bash # One shot, machine-readable deeptutor run deep_solve "Find d/dx[sin(x^2)]" --tool reason --format json # Chain turns in one stateful session — capture the id, reuse it SID=$(deeptutor run deep_research "Survey 2026 papers on RAG" \ --config mode=report --config depth=standard --format json \ | jq -r 'select(.type=="done").session_id') deeptutor run deep_question "Quiz me on that survey" --session "$SID" --format json ``` The repo ships a root [`SKILL.md`](SKILL.md) — a ~200-line handover doc that teaches any tool-using LLM the whole surface in one read. Hand it to Claude Code, Codex, or OpenCode (they pick up `SKILL.md` automatically), or wrap `deeptutor run` as a tool in a LangChain / AutoGen loop.

CLI-only distribution

The CLI-only package lives in `packaging/deeptutor-cli`. In this checkout, install it from source: ```bash python -m pip install -e ./packaging/deeptutor-cli ``` It isn't published to PyPI yet, so the main [Get Started](#-get-started) section keeps the source-install path.

## 🧩 Ecosystem — EduHub & the Skills Community DeepTutor skills use the open **Agent-Skills** format — a folder with a `SKILL.md` playbook (YAML frontmatter + Markdown) and optional reference files. Nothing about it is DeepTutor-specific, so any registry that speaks the format becomes a source for your library. DeepTutor ships with **[EduHub](https://eduhub.deeptutor.info/)** — our own education-focused skill registry — wired in as the default hub.

EduHub — DeepTutor's skill ecosystem

[**EduHub**](https://eduhub.deeptutor.info/) is the community hub DeepTutor launched for sharing teaching-oriented agent skills — Socratic tutors, flashcard builders, essay feedback, exam blueprints, concept explainers, and more. It is built into DeepTutor, so there's nothing to configure: a bare slug or an `eduhub:` prefix resolves to it. **Find and install** — in the browser, open **Learning Space → Skills → Import from EduHub** to browse the catalog and download a skill straight into your library. From the terminal: ```bash deeptutor skill search "socratic tutor" # search EduHub (the default hub) deeptutor skill install socratic-tutor # fetch → verify → register deeptutor skill install eduhub:socratic-tutor@1.2.0 # pin a hub and a version deeptutor skill list # local skills with their hub provenance ``` **Publish your own** — package a `SKILL.md` and share it back to the community: ```bash deeptutor skill login # browser sign-in to EduHub deeptutor skill publish ./my-skill # interactive: pick a track + tags, then upload deeptutor skill update # roll back or release a new version ``` EduHub is also a standalone, ClawHub-compatible registry, so agents that aren't DeepTutor (Claude Code, Codex, …) can use it directly through the `eduhub` CLI — `npx eduhub install socratic-tutor`.

The import safety gate

Whatever the source, every import passes the **same safety gate** before anything touches your workspace: - the registry's **security verdict** is checked first — flagged packages are refused unless you pass `--allow-unverified`; - archives are extracted defensively with path-traversal, entry-count, size, compression-ratio, suffix, and symlink checks; executable bits are stripped, while extensionless files remain allowed; - frontmatter is normalized to DeepTutor's schema and `always:` is **stripped**, so a downloaded skill can never force itself into every system prompt; - provenance — hub, version, verdict, and install time — is written to `.hub-lock.json` for audits and updates. In multi-user deployments, browser imports land in the authenticated caller's skill layer, while CLI and admin-console installs target the owner/admin workspace; admin skills stay hidden and read-only for ordinary users until granted.

Also compatible with ClawHub

Because DeepTutor speaks the open Agent-Skills format, **[ClawHub](https://clawhub.ai/)** works as a first-class source too — it's built in alongside EduHub. Pick it with the hub prefix: ```bash deeptutor skill search "git release notes" --hub clawhub deeptutor skill install clawhub:git-release-notes@1.0.1 deeptutor skill install clawhub:udiedrichsen/stock-analysis ``` When several publishers share the same slug, search shows each publisher and a fully scoped install ref (`clawhub:/`). Add more registries in `data/user/settings/skill_hubs.json`: a `type: "clawhub"` entry points at any compatible HTTP API (EduHub and ClawHub both speak it), `type: "command"` wraps whatever fetch CLI a registry ships, and `"default"` chooses the hub used for bare slugs. All of them feed the same import gate.
