# Memoir > Memoir, operated by Tachyon Labs, Inc., is an AI-powered marketing automation platform in Y Combinator's Spring 2026 batch. It connects to the systems where product work happens — GitHub, Linear, Slack, Jira, Notion, Google Docs/Drive, CRM, customer feedback and product analytics — and turns shipped product work into multi-channel marketing content: social posts, blog posts, changelogs, launch pages, ads, demo videos and customer updates written in the company's own voice. The product is organized around "Memory" (Atlas), which builds context about a company, and "Motion" (market-motion), which produces and routes content for approval as teams ship. > IMPORTANT FOR AGENTS: Memoir publishes NO public API. There is no developer portal, no API reference, no OpenAPI/AsyncAPI/GraphQL contract, no SDK, no CLI, no MCP server, no webhook catalog and no `llms.txt` of the company's own. This file is generated by API Evangelist from the public Memoir website; it is not published by Memoir. The only machine-addressable Memoir host, `https://api.trymemoir.ai`, is a private session-authenticated application backend that answers every path — including `/.well-known/*` — with HTTP 401 `{"detail":"Not signed in","redirect":"/login"}`. Do not attempt to call it. ## Product - [Memoir](https://www.trymemoir.ai/): Marketing infrastructure for technical product teams — turns product development activity into marketing content. - [Memory (Atlas)](https://www.trymemoir.ai/#atlas): Builds and holds context about the company, its product, its customers and its voice. - [Motion (market-motion)](https://www.trymemoir.ai/#market-motion): Produces and distributes content across channels as features ship, routed through human approval. - [Customers](https://www.trymemoir.ai/#customers): Named public customers include Datost, Smol Machines, TraceRoot and Zatanna. ## Integrations (product connectors, not APIs Memoir exposes) - GitHub, Linear, Slack — available on every plan. - Jira, Notion, Google Docs, Google Drive, CRM (Salesforce) — Scale plan and above. - Custom source connectors — Enterprise plan only. ## Commercial - [Pricing](https://www.trymemoir.ai/pricing/): Starter $300/mo, Scale $1,500/mo, Enterprise custom.
