Libragen

Create private, local RAG libraries that work offline—no API keys, no cloud services. Share them as single files your whole team can use.

GitHub

Create private, local RAG libraries from any documentation. Libraries are single SQLite files you can share with your team—no cloud, no API keys.

Why libragen?

  • Stop hallucinations — Give AI agents authoritative docs to cite instead of guessing
  • Always current — Rebuild when docs change; your AI gets the latest APIs
  • Private & local — Everything runs on your machine, nothing leaves your network
  • Shareable — Single .libragen files work anywhere

Packages

PackageDescription
@libragen/cliBuild and query libraries from the command line
@libragen/mcpConnect AI assistants to your libraries via MCP
@libragen/coreProgrammatic API for embedding, search, and library management

Quick Start

1. Build a library

# From local docs
npx @libragen/cli build ./your-private-docs --name company-docs

# From a git repository
npx @libragen/cli build https://github.com/anthropics/anthropic-cookbook --name anthropic-cookbook

2. Connect your AI

npx -y install-mcp @libragen/mcp

Restart your AI tool (Claude Desktop, VS Code, Cursor, etc.). Libraries in your global directory are now searchable.

3. Ask questions

"How do I implement tool use with Claude's API?"

"What's our internal policy on deploying to production?"

"Show me examples of streaming responses from the Anthropic cookbook"

Your AI retrieves relevant documentation and responds with accurate, cited answers—not hallucinated guesses from 2-year-old training data.

What else can you do?

  • Chat with your Obsidian vault — Tutorial →
  • Make your company's internal docs searchable — Runbooks, wikis, policies—all queryable by AI
  • Create a shared library for your team — One .libragen file, everyone's on the same page
  • Auto-build libraries in CI — Use the GitHub Action to generate .libragen files on every push
