Open Brain — The infrastructure layer for your thinking. One database, one AI gateway, one chat channel — any AI plugs in. No middleware, no SaaS.

Editor's note

Open Brain is a self-hosted personal knowledge infrastructure built around a Supabase database with vector search, an AI gateway (via OpenRouter), and a Slack channel for thought capture. The MCP server component exposes stored memories to any MCP-compatible client, meaning Claude Desktop, Claude Code, Cursor, or other tools can all read from and write to the same persistent memory layer without duplicating data across services. Setup takes roughly 45 minutes following the provided guide and requires no coding experience, though an AI-assisted path using Claude Code or Cursor is also documented. Extensions cover use cases including a professional CRM with full-text search and meeting prep, an Obsidian vault importer, a wiki synthesis pipeline, and entity extraction. A recent community contribution reduced edge function invocation costs by 73%. The project is aimed at individuals who want AI tools to share a unified, portable record of their knowledge and context without relying on third-party SaaS memory products.

Install

Continuous learning system that extracts reusable knowledge from work sessions. Triggers: (1) /aiception command, (2) 'save this as a skill' or 'extract a skill from this', (3) 'what did we learn?', (4) after non-obvious debugging or trial-and-error discovery. Creates new skills when valuable reusable knowledge is identified. Integrates with Open Brain to prevent duplicates.

Install

Use when processing voice transcripts, brain dumps, stream-of-consciousness notes, or any raw multi-topic capture. Extracts every idea thread, then evaluates each one with deep brainstorming, then captures results to Open Brain. Trigger on transcripts, exports, "process this", "pan for gold", "brain dump", "what did I say", or multi-topic markdown files.

Install

Use when a user asks to read, analyze, summarize, or extract from a heavyweight file such as PDF, DOCX, PPTX, XLSX, CSV, or TSV. Convert the file into markdown or CSV first, generate a lightweight index, and only spend model tokens on the compressed artifact. Trigger on requests like "read this PDF", "look through this spreadsheet", "summarize this deck", or any time raw file ingestion would waste tokens.

Install

Use in Claude Code when a user asks to read, analyze, summarize, or extract from a heavyweight file such as PDF, DOCX, PPTX, XLSX, CSV, or TSV. Convert the file into markdown or CSV first with the bundled script, generate a lightweight index, and only spend model tokens on the compressed artifact.

Install

Use in Claude Desktop when a user asks to read, analyze, summarize, or extract from a heavyweight file such as PDF, DOCX, PPTX, XLSX, CSV, or TSV. Avoid raw ingestion of bulky files. Ask for a converted markdown or CSV artifact first, or give the user exact conversion commands to run outside Claude Desktop.

Install

Use in Codex when a user asks to read, analyze, summarize, or extract from a heavyweight file such as PDF, DOCX, PPTX, XLSX, CSV, or TSV. Convert the file into markdown or CSV first with the bundled script, generate a lightweight index, and only spend model tokens on the compressed artifact.

Design, evaluate, and improve agentic harnesses for developer tools, assistants, workflow runtimes, copilots, and AI-powered products. Use when work involves tool-use architecture, permissions, approval gates, workflow state, durability, context and memory systems, evaluation strategy, observability, operator visibility, or phased implementation plans for an AI system. Trigger when symptoms imply harness gaps too: stale context, surprising tool calls, sessions that die on crash, missing approval controls, or costs spiraling without clear visibility.
