You choose which model may read your memory, and a human governs it. On LongMemEval-M holdout questions, never used to tune the engine, it scores **77.1%** in hybrid mode: embeddings and search on your machine, answers from a cloud model, gemini-3.8-flash ([audit it yourself](https://github.com/Mnemosyne-OS/MnemosyneOS---benchmarks/tree/main/longmemeval-rerun-2026-10)). The AI that remembers *you*, not infrastructure you plug into someone else's. ### Where the project lives Published by **XPACEGEMS LLC**. These are its official addresses: | | | |---|---| | **Product** | [mnemosyne-os.io](https://mnemosyne-os.io) | | **Organizations** | [mnemosyne-os.com](https://mnemosyne-os.com) | | **Documentation** | [docs.mnemosyne-os.io](https://docs.mnemosyne-os.io) | | **Source** | this repository | | **Packages** | the npm scope `@mnemosyne_os`: [the list](https://mnemosyne-os.io/packages) | --- ## Why call it an "OS"? Not because it has a kernel or drivers. Because it does what an OS does: **it manages resources on behalf of processes that shouldn't have to manage them themselves.** Linux does that for programs (CPU, RAM, disk, network). Mnemosyne OS does the same thing for **AI agents**, and the resources are just different: | An agent needs | Mnemosyne OS manages it via | |---|---| | **Memory** | Vaults, SQLite + vector stores, partitioned by domain, with AES-256 encryption at rest you arm | | **Context** | Chronicles + semantic retrieval, the agent never rebuilds its past by hand | | **Compute** | Routing across model tiers (budget/standard/premium, local/cloud) by task complexity | | **Hardware** | Real GPU/CPU dispatch for local speech (CUDA detection, isolated sidecars) so a heavy model never blocks the app | | **I/O** | A signed intent protocol (query / ingest / forget / focus) instead of raw reads and writes | | **Security** | FGAC, scoped JWTs, Zero-Trust IPC validation | | **Persistence** | Cross-session continuity, no cold start on every invocation | This isn't a marketing stretch invented for this repo. **MemGPT** (Packer et al., UC Berkeley, 2023, [arXiv:2310.08560](https://arxiv.org/abs/2310.08560)) proposed the same "OS for LLMs" analogy in a peer-reviewed paper, virtual context management modeled on OS memory hierarchies. Mnemosyne OS takes that same premise further: not a single-session context-paging technique, but a system that runs continuously, isolates multiple agents, and persists on the machine as a daemon, not a library you import and lose on exit. --- ## The flagship app: Mnemosyne OS Infinity Edition The reference application of the ecosystem: a **local-first AI Operating System** that puts a sovereign memory core under strict user control. It runs LLMs locally or in the cloud, keeps every encrypted vault on your machine, and, for agent-to-agent sync, can speak over a **libp2p** transport (`@mnemosyne-workspace/mnemosync-p2p`). Unlike fragmented AI wrappers, Mnemosyne OS never exposes your knowledge vault indiscriminately. Every agentic connection is governed by **FGAC (Fine-Grained Access Control)** and 400 Zod-validated IPC channels, ensuring total sovereignty over what executes, what's stored, and what syncs. ### Core Modules | Module | Description | |--------|-------------| | 🧭 **Neural Map** | Your memory rendered as a living mathematical topology, nodes are memories, edges are semantic similarity between them, tuned live | | 🧩 **MnemoHub** | A store of cartridges (mini-apps) whose catalog is signed by a sovereign wallet and verified client-side before anything renders | | 💤 **Dream State** | A consolidation engine that replays and links memories during idle phases | | 🗄️ **Vaults** | Memory partitioned by life domain, each with its own protection level and consent boundary | | 🎙️ **Voice Assistant** | Local or cloud speech, streaming STT/TTS, gapless local playback | | 💬 **Multimodal Chat** | Text, voice, and file-grounded conversation with live retrieval from your own vaults | | 🧠 **Adaptive RAG** | Retrieval depth and ranking scale to the model you're running, laptop LLM to frontier cloud model | | 🔑 **Sovereign Wallet & Engramm License** | A local Web3 wallet drives licensing (verified on Base), pseudonym claims, and cloud credits, no account, no password, no gas fees | | 🎨 **Spatial Canvas** | Widgets live on a 2D canvas, not stacked tabs, position carries meaning | | 🛩️ **Agent control room** | Your coding agents appear as cards on the canvas, through herdr.

Spine engine, memory, semantically classified · Adaptive RAG, retrieval that shifts gears · Dream State, consolidation while you sleep · Voice engines, local STT and TTS, GPU or CPU · Embeddings, cloud, local ONNX or Ollama

Not one big "AI" black box. Several independent, purpose-built engines: - **Embedding engine**: a priority-ordered chain of embedding providers (cloud, local ONNX, Ollama). Tries each in order and **fails loud rather than returning a null vector**, a failed embedding must never silently become an invisible memory. - **Retrieval engine**: an in-RAM, decrypted vector cache (int8-quantized to scale), ANN search unioned with exact term matching before the final re-rank pass. - **Spine engine**: classifies every memory by semantic nature (its "spine" + tags), from a taxonomy that lives as **data**, not hardcoded logic, so new categories don't require a code change. - **Dream State**: two-speed consolidation. A fast, low-latency tier extracts facts during active use; a heavier tier runs at idle/night to resolve contradictions and link memories across sessions. Output is appended alongside raw retrieval, never silently replacing it. See the [benchmark results](#proven-on-longmemeval-m-not-just-a-pitch) below. - **Adaptive RAG (the "gearbox")**: rather than injecting every retrieved candidate, context selection (top-k / MMR / low-discrepancy sampling) scales to both the model tier you're running and the thinking mode you pick. - **Theia, the vision engine**: named for the Titaness of sight, who in the myth is Mnemosyne's sister. A complete image-memory engine: your images are embedded **100% locally** (SigLIP 2, in an isolated sidecar) into their own vector space, recalled in chat as thumbnails through three rank-fused channels: semantic, pixel-color palette, and emergent categories the engine discovers on its own, and browsed in a living gallery. **The human always outranks the model**: rate, pin, describe, teach, rename or merge its categories. Honest by construction: a cold or still-indexing engine says so, instead of inventing "no matches". Off by default, behind one Settings toggle. - **Voice engines, STT and TTS, fully independent**: speech-to-text runs small models in-process and large models in an **isolated GPU/CPU sidecar** (a big STT model loaded in-process can crash the whole app); text-to-speech runs system, cloud, or local (offline binary or GPU voice cloning), scheduled sample-accurately for gapless playback. No NVIDIA GPU → automatic CPU fallback, never a hard block. - **400 Zod-validated IPC channels** connect all of the above to the UI, auto-generated and checked by a drift test on every build. > 📄 **Deep dive:** [**The Resonance Engine**, technical whitepaper](doc/RESONANCE_ENGINE_WHITEPAPER.md). > The full architecture behind these engines: why memory should *resonate* rather than be looked > up, how consolidation and adaptive selection work, and the LongMemEval results, kept current as the engine ships. > > 📚 **Full documentation**: the user guide lives at [docs.mnemosyne-os.io](https://docs.mnemosyne-os.io); concepts, architecture, governance, and design decisions live in [`doc/`](doc/). ### How memory works ```mermaid flowchart LR A["Document · conversation · file"] --> B["Vault

Its **full-haystack** variant surrounds every question's evidence with ~480 distractor sessions, the closest published setup to a real, lived-in memory vault, and harder than the `-S` slice most reported numbers use. **The protocol was published before the run.** The holdout questions had never been answered before. The run uses the hybrid mode: embeddings and search run on the machine, and a cloud model, gemini-3.8-flash, writes the answers. It measures the SDK and MCP door that agents use. In September an [outside audit by Julien Gelee](https://github.com/Mnemosyne-OS/Mnemosyne-Neural-OS/pull/47) found a wrong verdict in our August result. It covered the published files, ledgers and arithmetic, and did not evaluate the product or the closed engine. The [erratum](https://github.com/Mnemosyne-OS/MnemosyneOS---benchmarks/blob/main/ERRATUM.md) corrects it to 35/48 (72.9 %) under the strict judge and 37/48 (77.1 %) under the flexible one. We then ran the whole benchmark again. July's composed 72.9 % stays archived under its DOI. The reader, the engine and the judges changed between these runs, so the figures sit side by side and never chain into a progression. **Don't take any of it on faith. Audit it.** The published grader and per-question verdicts let you re-derive every score in one command, no engine and no network. Full methodology, root-cause analysis, and the raw run logs of both campaigns are public too: **🔍 [Audit it yourself: every answer and a verify.js →](https://github.com/Mnemosyne-OS/MnemosyneOS---benchmarks/tree/main/longmemeval-rerun-2026-10)** · [live results page](https://mnemosyne-os.github.io/MnemosyneOS---benchmarks/verification-kit/) · [raw logs & methodology](https://github.com/Mnemosyne-OS/MnemosyneOS---benchmarks) **Citing this work.** Both the evidence and the architecture are archived under permanent identifiers, so they can be cited rather than merely linked: | | | |---|---| | Verification kit, ledgers, grader, raw logs | [10.5281/zenodo.21727140](https://doi.org/10.5281/zenodo.21727140) | | The Resonance Engine, technical whitepaper | [10.5281/zenodo.21728283](https://doi.org/10.5281/zenodo.21728283) | | Author | Tony Trochet · [ORCID 0009-0009-1087-3917](https://orcid.org/0009-0009-1087-3917) | ### Interface Gallery

Sovereign Notes: write in a local, classified vault, every note is embedded and retrievable, feeding the same memory your agent draws on

--- ## Two doors between your IDE and your memory You already run an agent next to your editor. It opens every session without the history of the project it is working in, so it reasons its way back to conclusions you reached weeks ago, and it will do that again tomorrow. Part of that history survives: the agent wrote it down itself. It sits in a dot-directory beside the code, usually gitignored, read by nothing. Mnemosyne OS opens two doors onto it, and they run in opposite directions. **Door one, memory reads the agent.** DocWatch watches a folder you deliberately point at, whatever its name, so `.claude/…/memory` is treated like any other source and what your agent noted becomes retrievable next to your documents and your code. Shipped in **v1.4.3**: before that a blanket ignore rule dropped every dot-directory, in silence. → **[Connect your coding agent's memory](https://docs.mnemosyne-os.io/developers/agent-memory)** **Door two, the agent reads memory.** [`@mnemosyne_os/mcp`](https://www.npmjs.com/package/@mnemosyne_os/mcp) is a Model Context Protocol server: one entry in your client config, and the agent can search a vault, ask it a question in prose, and write back what it worked out. ```bash npx -y @mnemosyne_os/mcp ``` → **[Connect Claude to Mnemosyne OS (MCP)](https://docs.mnemosyne-os.io/connect-claude-mcp)** Three of those tools need neither the app, nor a vault, nor a single token: they read the transcripts your harness already writes to disk. That is what makes *"is another session live on this branch before I commit?"* cheap enough to actually ask. > **The mechanism is the whole claim.** We publish no measurement of what this saves in > tokens or in minutes, so we assert none. Retrieval is not reasoning: a decision a model > can look up is a decision it does not derive a second time, and the context it would > have spent reconstructing where it is goes to the task instead. Watch it in your own > sessions rather than taking a number for it. --- ## Build on Mnemosyne OS You've seen what it is and that it works. Now build on it. Your apps, agents, and skins talk to the private AI memory runtime through a **public Gateway contract**: a stable, documented surface you build against, while the Cognitive Core stays sealed and never exposed. Two ways in: - 🛠️ **Build on it**: copy the [cartridge boilerplate](examples/cartridge-boilerplate) for an app inside the Mnemosyne window, or scaffold a separate program and you're talking to the memory vault in minutes. - 💾 **Run it**: install the flagship desktop app, [Infinity Edition](https://github.com/Mnemosyne-OS/Mnemosyne-Neural-OS/releases/latest). ```bash npm create @mnemosyne_os/app # a Layer 2 app: a separate process, not a cartridge ``` | Package | What it does | |---|---| | [`@mnemosyne_os/cartridge-sdk`](https://www.npmjs.com/package/@mnemosyne_os/cartridge-sdk) | Build a cartridge: an app inside the Mnemosyne window, in a sandboxed iframe | | [`@mnemosyne_os/sdk`](https://www.npmjs.com/package/@mnemosyne_os/sdk) | Connect a separate program (a Layer 2 app) to the local AI memory runtime (WebSocket / Electron IPC) | | [`@mnemosyne_os/public-contracts`](https://www.npmjs.com/package/@mnemosyne_os/public-contracts) | Shared types & Zod schemas, the integration contract | | [`@mnemosyne_os/design-sdk`](https://www.npmjs.com/package/@mnemosyne_os/design-sdk) | Build custom UI skins in pure JSON, zero TypeScript | | [`@mnemosyne_os/create-app`](packages/create-app) | Scaffold a Layer 2 app in one command. Not a cartridge: MnemoHub refuses to link it | Start from the [cartridge boilerplate](examples/cartridge-boilerplate) and you're ingesting and querying the vault, under FGAC, scoped, and consent-gated, in minutes. > **🛡️ Zero-Trust by design.** Every SDK connection authenticates with a short-lived > JWT, listens on `127.0.0.1` only, and is bounded by the scopes your app manifest > declares. The OS sees your requests; you never see the core. ### The cartridges are real, and readable The apps in MnemoHub aren't black boxes. Each ships its actual `src/` (React + the SDK), public and inspectable. **Clone one as a reference implementation** and read exactly how a real app connects to the memory runtime, ingests, and queries the vault through the SDK. Don't learn the SDK from API docs alone, download a working app and copy the patterns.

The **Cartridge License** is source-available: read it, learn from it, modify it, with one condition: it runs inside the Mnemosyne OS ecosystem.* > **🧩 Make your own.** Scaffold a cartridge from the [boilerplate](examples/cartridge-boilerplate), > build it against the SDK, and publish it to MnemoHub, exactly how these were made. From `npm create` > to a signed, installable cartridge, the whole path is yours. --- ## The open ecosystem The open surface of Mnemosyne OS is **MIT-licensed** and free to build on: - **Layer-2 SDK** (`/packages`) is the integration surface above: connect apps, build skins, scaffold projects, evaluate against the Gateway. - **MnemoForge CLI** (`/cli`) is a separate developer tool with its own docs: see [`cli/README.md`](cli/README.md). To give a coding agent memory, use the [MCP server](packages/mcp) instead. --- ## Why it's safe to build on The open SDK and the sealed core are separated by a single boundary: the **Gateway**. Apps speak a public contract; the core's internals are never shipped to, or reachable from, third-party code. ```mermaid flowchart TB subgraph Renderer["Renderer Process (React)"] UI["React 18 · TypeScript strict · Vite

Fitting for a memory OS: it's your own verifiable trace of ownership. Rather than an account and a monthly subscription, your license lives on-chain (Base), bound to your wallet, not to a machine, not to an email. You hold it, so you own your copy and carry it to any device you want, and anyone can verify it. The same Engramm drives your sovereign pseudonym and cloud credits. Holding it and checking it cost you nothing. See below. ### Auth: cold boot / warm boot A local wallet is the only credential. No account, no password server-side to breach. > **No gas fees, no crypto to manage.** The chain is plumbing, not a paywall. You never pay a > network fee, hold a token, or approve a transaction. Ownership is recorded on Base so it stays > publicly verifiable, but every network cost is covered for you.

Sovereignty**: Your data stays local. Your models run locally if you choose. No telemetry without consent. FGAC controls what the AI can and cannot access. **2. Multi-model**: No vendor lock-in. Claude, GPT, Gemini, Groq, Mistral, DeepSeek, and MiniMax in the cloud; Ollama or a local GGUF model fully offline; any OpenAI-compatible endpoint on top. Switch per task, or let the app route automatically. **3. Agentic by design.** This is not a chat interface with file upload. A real orchestration layer where multiple AI agents coordinate, with policy enforcement and audit trails. --- ## 🔬 Mnemosyne Labs: research, activated Mnemosyne Labs, open research program.

Off by default; one Settings toggle installs, downloads pinned weights and indexes. - [x] 🕸️ **Synaptic P2P** (beta, since v1.5.0): two installs connect directly over libp2p, with no cloud relay. Give someone a vault to read, send mail between installs, keep one vault together, and give each of your machines a role - [x] 📚 **Memory cartridges**: public knowledge fetched from its official source into your memory, starting with laws, medicine, science, world history, known vulnerabilities and trademarks - [x] 🖐️ **Voice and gestures** (v1.7.0, gestures out of beta in v1.8.0): drive the canvas with your voice and your hands - [x] 🧩 **MnemoHub**: signed cartridge marketplace, community submission pipeline, live publishing - [x] 🪪 **Sovereign identity**: claim a public pseudonym bound to your wallet, no account, no password - [x] 💤 **Dream State**: a consolidation engine that replays and links your memories while you're away - [x] 🗜️ **Octave, multi-resolution memory compression**: the engine behind the compression milestone, aboard since v1.3.8: while you're away, consolidation prepares each memory at several resolutions, so the answer path can carry more memory into a small context window. Strictly extractive: every compressed line is a verbatim excerpt of the original, provable by character offsets, never a paraphrase: and compressed derivatives inherit the exact vault protection of their source. Serving them on the answer path stays off by default until the full benchmark campaign clears it. - [x] ⚡ **MnemoForge CLI v1.4.7** on npm, [`@mnemosyne_os/forge`](https://www.npmjs.com/package/@mnemosyne_os/forge) · Soul Protocol · Canvas Rules · Chronicle System · MCP Server - [x] 🌱 **Public beta, v1.1.0-beta.1**: where it started (personality-profile builder, semantic memory graph, first-contact onboarding) ### What's next - [ ] 🗜️ **Context compression, on by default**: the Octave engine is already aboard (see *Shipped*). While your machine is idle, every memory is prepared at several resolutions, strictly extractive, offset-provable, never a paraphrase. What remains is serving those compressed forms on the answer path for everyone, gated behind the full measurement campaign, so a lifetime of accumulated memory stays cheap to carry into the small **context windows** of on-device models. Memory that keeps growing must stay cheap to carry, this is what keeps Mnemosyne sovereign on modest hardware. - [ ] 📱 **Mobile companion app**: take notes and reach Mnemosyne OS running on your desktop remotely. Capture on the go, sync back into your local vault, chat with your own memory away from the machine - [ ] 👥 Team features: memory shared across a whole team, beyond one shared vault - [ ] 🖥️ Self-hosted sync server - [ ] 🕸️ **Permaweb archival**: pay-once, permanent memory storage on Arweave, no subscription and no server that can disappear. [Psyche](https://psyche.mnemosyne-os.io) (souls for any AI agent) is the vehicle; bringing it into Mnemosyne OS as a cartridge is the path to making permanent archival a native option for chronicles, and eventually vault backups - [ ] 💰 Creator economy, paid visibility for cartridges, revenue flowing back to builders --- ## About **XPACEGEMS LLC**, Independent AI software lab **Headquarters:** 2932 NW 72 AVE, Miami, FL 33122, USA **Founder & Lead Architect:** Tony Trochet **Product:** [mnemosyne-os.io](https://mnemosyne-os.io): downloads, docs, build on it **Company:** [mnemosyne-os.com](https://mnemosyne-os.com): press, research, [Labs](https://mnemosyne-os.com/labs) **Documentation:** [docs.mnemosyne-os.io](https://docs.mnemosyne-os.io): every engine, step by step **LinkedIn:** [Tony Trochet](https://www.linkedin.com/in/tony-t-19544650/) **GitHub:** [@yaka0007](https://github.com/yaka0007) > Built through **Neural Coding**, human-architected, with Claude (Anthropic), Antigravity (Google DeepMind), and Cursor directed as instruments. --- ## 📰 What's new A new build ships most weeks. Windows builds are **code-signed** (Certum OV, RFC-3161 timestamped) and auto-update once installed. | Date | Release | In one line | |------|---------|-------------| | **Oct 17, 2026** | [**v1.9.0 · The Orb**](https://github.com/Mnemosyne-OS/Mnemosyne-Neural-OS/releases/tag/v1.9.0-infinity) | The orb becomes your assistant. **She drives your apps**: say "tidy my desktop" and she plans the steps and runs them, on the board, on an empty desktop or pinned above all your applications. She now also understands German, Portuguese, Russian and Chinese. Your day comes to the board: the morning briefing and the evening journal read aloud, Google Calendar and your mail, meetings prepared on a card, and Sentinel, an alarm for your desk while you are away. **Your coding agents drive Mnemosyne OS** from Claude Code, Cursor, Codex or any IDE connected to the MCP server, and every call is written to a journal on your machine. Also new: IDE Timeline, YouTube in an app (beta) and memory on an NVIDIA card (beta). Many features are still experimental. | | **Oct 8, 2026** | [**v1.8.0 · The Library**](https://github.com/Mnemosyne-OS/Mnemosyne-Neural-OS/releases/tag/v1.8.0-infinity) | The knowledge memories open. **Knowledge apps in the MnemoHub** download public knowledge into vaults of their own: laws, history, health, science and languages. You ask the chat, and it answers from them. Hand gestures are out of beta. Every app in the Hub has its own page, with photos, reviews and its version, and a Dev section plugs Claude Code, Codex, Antigravity or Cursor into your memory. Ask the chat about a period, and MnemoClio opens on that year. Also new: apps on a desktop of their own, starter questions in an empty chat, the weather from the orb, and spending split by route in the wallet. | | **Oct 2, 2026** | [**v1.7.0 · The Hands**](https://github.com/Mnemosyne-OS/Mnemosyne-Neural-OS/releases/tag/v1.7.0-infinity) | You can now drive your board with your hands, through your webcam (beta). Pinch a window’s corner to move it, spread your fingers for full screen, or hold a fist to close it. A second pass can check a chat answer against its sources. Your coding agents appear as cards on your board, through herdr. Also new: web search through Hermes, formulas in the chat and layers in the image studio. And an arcade on the neural map, data widgets (beta) and larger local models. | | **Sep 23, 2026** | [**v1.6.0 · The Assistant**](https://github.com/Mnemosyne-OS/Mnemosyne-Neural-OS/releases/tag/v1.6.0-infinity) | Mnemosyne OS can now run an assistant that works for you. **Hermes Agent installs in one click** (beta) through the MnemoHermes cartridge, reads your memory, and answers you on Telegram, by voice if you like. Before a risky command, it asks you on a card on your board, and you answer once, for the session, or always. Voice notes are transcribed on your machine. Say "Hermes, …" to the orb and it hands the request over. Exact-word search now reads seven languages, and a file name in your question finds that file. Also new: OpenRouter as a provider, Tailscale in the P2P screen to reach a peer on another network, and every call listed in the wallet. | | **Sep 19, 2026** | [**v1.5.1 · The Key Found Again**](https://github.com/Mnemosyne-OS/Mnemosyne-Neural-OS/releases/tag/v1.5.1-infinity) | A fix for Mac. Changing network renamed the machine, and the sovereign wallet closed with your credits inside it. The app now finds the key again at startup and reseals it, and the offline licence holds through the same rename. | | **Sep 18, 2026** | [**v1.5.0 · The Synapse**](https://github.com/Mnemosyne-OS/Mnemosyne-Neural-OS/releases/tag/v1.5.0-infinity) | Two installs can now connect. **Synaptic P2P** (beta) gives someone a vault to read, sends courier mail and shares one vault that several people write. You can tell the app what to do, spoken to the orb or typed in the chat: "open my agenda", "full screen", on any window, in your language, plus the phrases you teach it in Settings › Commands. The recorder transcribes with timestamps and recognises your enrolled voice. Also new: a memory health panel, an ask line on a blank desktop, external shortcuts pinned on the board, agent cards in the cockpit, the chat acting on your agenda and backlog, and MCP 2.0 with a one-click install for Claude Desktop. More than 500 commits since 1.4.5, more than 200 of them fixes. | | **Sep 8, 2026** | [**v1.4.5 · The Locked Door**](https://github.com/Mnemosyne-OS/Mnemosyne-Neural-OS/releases/tag/v1.4.5-infinity) | A repair release that grew a beta. The headline is a lock: **only a cartridge you linked yourself in developer mode can start a script on your machine**: a Hub cartridge could declare a development address and run its script the moment its window opened, so every install on 1.4.4 or earlier should take this one. Behind it, a zone-by-zone pass of 650 commits and 285 fixes: **the chat answers in under a second instead of freezing for a minute**, it searches by exact words again (the lexical channel had only ever served the SDK, not the chat), the Dream State dreams a whole topic instead of its first forty pieces, a watched-folder rule applies to that folder alone, and every number nobody measured reads *unknown* instead of 0. New: **drive the board with your hands** (Settings › Gestures, beta, pinch to grab, two hands to zoom, swipe), a **conversation recorder** that keeps you and the other side on two tracks with no speaker model, a **portable cartridge** that carries a memory to another machine on a drive, **« Ask »** in the capture browser to question your memory about the page you are on, **eight new MCP tools** so an agent can read, change and remove your To-do and Agenda even with the app closed, words-only vaults for code, a neural map with one settings drawer and a brain figure, and an AFFiNE import. | | **Sep 3, 2026** | [**v1.4.4 · The Whole Document**](https://github.com/Mnemosyne-OS/Mnemosyne-Neural-OS/releases/tag/v1.4.4-infinity) | For anyone who drops real documents into a vault: **a long document now enters memory whole**. It was cut at 18 000 characters, so a 300-page book was remembered as its first six pages. A file refused outright said nothing at all, and two 150-page courses had been turned away in complete silence; a refusal now names the file, its size and the rule it broke. PDF, Word and Excel go from 5 MB to 50 MB. For a company: point Mnemosyne at **your own OpenAI-compatible model server** on your own network, and the route is yours end to end. The chat reads **several vaults at once**, follows the vault you picked in the panel, or lets the model choose per question. **Ask Mnemosyne about Mnemosyne**: a manual ships inside the app in French, English and Spanish, and says plainly when it has no page on your subject. The **capture browser** is rebuilt for the web: every image of a page in one click, or the page as text, as a PDF, as a screenshot, all reviewed before any of it becomes memory. Plus a problem report from any window that shows you what gets sent before you send it, images pasted inside a `.docx` kept and indexed, and a boot that stopped rebuilding the neural map eleven times per launch. | | **Aug 31, 2026** | [**v1.4.3 · What Your Agent Knows**](https://github.com/Mnemosyne-OS/Mnemosyne-Neural-OS/releases/tag/v1.4.3-infinity) | For anyone who codes with an AI agent open beside them: **your agent's memory can finally enter a vault**. Every agent keeps what it learned under a dot-directory (`.claude`, `.cursor`, `.aider`, `.continue`), and a blanket ignore rule dropped all of them whole, in silence: the source read enabled, the panel showed a green dot, the log said the watch had attached, and not one file was ever ingested. A folder you deliberately point at is now watched, whatever its name. Searching **through the MCP** also gains the exact-word channel the app's own retrieval already had. Plus the work that piled up behind the 1.4.2 cut: **desktops on the canvas** (a desktop is a world, with its own windows, camera and decor), a **to-do rework** with lists of your own, an archive that is not a delete, drag to reorder, and tasks that leave the list to sit on the canvas and ring; notes that **open in a window of their own**; vaults readable from across the board; and a vault's weight that says who answers without ever stopping it from recording. | | **Aug 29, 2026** | [**v1.4.2 · The Clean Cut**](https://github.com/Mnemosyne-OS/Mnemosyne-Neural-OS/releases/tag/v1.4.2-infinity) | Cut a subject out of any image **on your own machine**: right-click it on the canvas, and put the background back in one click, the original file is never touched. Two permissively-licensed models, the choice yours in Settings. Image memory can now use an **NVIDIA GPU**, and nothing is marked upgraded without proof it booted on one. A new room for making pictures: several plans open at once, your own images as a **brand kit** a generation must honour, and a prompt Mnemosyne writes out of your own memory. **Oikos** reads the devices in your house and keeps a still of them where your memory can find it a year later, one approved device at a time, addresses you declare, polling that stops the moment you withdraw consent. And the canvas travels: opening a window flies to it, with a way back from every trip. | | **Aug 26, 2026** | [**v1.4.1 · The Closed Pipe**](https://github.com/Mnemosyne-OS/Mnemosyne-Neural-OS/releases/tag/v1.4.1-infinity) | Linux fix: launching the AppImage from a terminal that was later closed broke standard output, and every log line then raised a fatal error dialog, one per line. The log bus now detects the closed pipe and keeps the ring buffer and the daily file, which is the path packaged builds actually use. Also, a scanned book is read whole: OCR reads a document in page windows instead of stopping at 60 pages, and says which page it is on. | | **Aug 25, 2026** | [**v1.4.0 · The Infinite Vision**](https://github.com/Mnemosyne-OS/Mnemosyne-Neural-OS/releases/tag/v1.4.0-infinity) | Mnemosyne learns to **see**: Theia, a fully local image-memory engine (SigLIP 2, on-device), makes your photos recallable in chat, ask for *"the pieces that look like a blue cup"* and the thumbnails answer, with a living gallery (day timeline, stars, pins, and categories the engine discovers and **you** can correct or teach). The workspace unlocks into an **infinite canvas** you pan, zoom and decorate with clocks, weather and stickers; paste or drop an image anywhere and a vault picker turns it into memory; a sandboxed **capture browser** (beta) brings the web in, one human gesture per capture, never automatic. Plus: local models fixed on fresh installs, gapless local read-aloud, and a notes rework with a constellation view and five-colour highlights. | | **Aug 18, 2026** | [**v1.3.8 · The Second Channel**](https://github.com/Mnemosyne-OS/Mnemosyne-Neural-OS/releases/tag/v1.3.8-infinity) | Retrieval gains a second, fully local channel: your vault is now also ranked by **exact words** (BM25 over a persistent index built inside the vault) and fused with the semantic ranking by rank, a proper noun, an identifier or a number now finds its session. Measured on LongMemEval full-haystack, strict judge: **29 → 37 of 48**, reproduced twice, confirmed on held-out questions with zero regressions. Plus per-app isolation proven on every retrieval channel, and an installer with a proper trilingual EULA that launches the app when it's done. Also aboard: **Octave**, a multi-resolution memory-compression engine, strictly extractive, off by default on the answer path until measured. | | **Aug 10, 2026** | [**v1.3.7 · The Kept Promise**](https://github.com/Mnemosyne-OS/Mnemosyne-Neural-OS/releases/tag/v1.3.7-infinity) | The whole loop runs on your machine, model, memory and retrieval, with no key and no account. A refreshed local catalogue with **262k-token context windows** (the entry-level model shipped with 4k), your own `.gguf` files welcome, bring-your-own-key providers that hand you *their* real model list, a local journal of what every call costs at **your** prices, and vault protection the routing now honours end to end. | | **Aug 3, 2026** | [**v1.3.6 · The Persona**](https://github.com/Mnemosyne-OS/Mnemosyne-Neural-OS/releases/tag/v1.3.6-infinity) | The OS takes your shape: four new shell languages (Deutsch, Português, Русский, 中文), abstract voice-orb skins with a full-screen mode, a user-chosen accent that cartridges inherit live, a sixteen-archetype cognitive lens that styles the voice without ever touching retrieval, and web search rebuilt. | | **Jul 29, 2026** | [**v1.3.5 · The Sealed Vault**](https://github.com/Mnemosyne-OS/Mnemosyne-Neural-OS/releases/tag/v1.3.5-infinity) | Opt-in **AES-256 encryption at rest** with a 24-word recovery phrase, backups decided by an allow-list of what is genuinely yours, and ~10 GB of machine-bound toolchain moved out of the data folder. | | **Jul 22, 2026** | [v1.3.4](https://github.com/Mnemosyne-OS/Mnemosyne-Neural-OS/releases/tag/v1.3.4-infinity) | The first **code-signed** Windows build, no more "unknown publisher". | | **Jul 20, 2026** | [**v1.3.3 · The Sovereign Ledger**](https://github.com/Mnemosyne-OS/Mnemosyne-Neural-OS/releases/tag/v1.3.3-infinity) | The credit economy: in-app credit and license flow, a creator cockpit for cartridge builders, sovereign pseudonyms backed by a real install counter. | | **Jul 19, 2026** | [**v1.3.0 · The Memory Covenant**](https://github.com/Mnemosyne-OS/Mnemosyne-Neural-OS/releases/tag/v1.3.0-infinity) | The sealed core, app-sandbox vaults with human-gated permanence, and memory-purge governance. | | **Jul 7, 2026** | [**v1.2.0 · The Reading Engine**](https://github.com/Mnemosyne-OS/Mnemosyne-Neural-OS/releases/tag/v1.2.0-infinity) | A PDF library that reads to you, deferred local OCR, voice reading, and the spine memory engine underneath. | **[→ All releases](https://github.com/Mnemosyne-OS/Mnemosyne-Neural-OS/releases)** ### ✍️ From the blog The longer stories behind the releases and the campaigns, on the product site: - **[A multiplier cannot rescue a zero](https://mnemosyne-os.io/blog/a-multiplier-cannot-rescue-a-zero)**: dense embeddings can't hear a rare proper noun. What worked: a second, fully local ranking fused by rank, with two reproduced runs, a 48-question holdout, and every number auditable. - **[72.9%: and the three questions we miss](https://mnemosyne-os.io/blog/full-haystack-72-9)**: LongMemEval on the full-haystack variant, the one nobody shows: the number, the protocol, the levers we refuted, and the misses we own. - **[We gave personality control of memory. It cost 31 points.](https://mnemosyne-os.io/blog/personality-lens-31-points)**: the most seductive feature we built this year made retrieval measurably worse; the ablation, and why personality shipped as a costume. - **[Present is not the same as loadable](https://mnemosyne-os.io/blog/a-release-that-could-not-load-a-model)**: a package can be there, at the right version, and still be unreachable to the code that imports it. - **[The memory my brain kept asking for](https://mnemosyne-os.io/blog/la-memoire-que-mon-cerveau-reclamait)**: why this OS exists: not a product, a prosthesis for a brain that ran too fast for the world. *([original in French](https://mnemosyne-os.io/fr/blog/la-memoire-que-mon-cerveau-reclamait))* **[→ All posts](https://mnemosyne-os.io/blog)** ---
