Reference is local semantic search for your files and code, built for AI agents. No cloud, nothing leaves your machine. Ask it "how did I implement rate limiting here" and get your actual code back, cited down to the exact function, not generic advice. Live index that updates as you save, code-aware chunking (tree-sitter), and a built-in MCP server (/search, /explain, /find_similar, /check_doc_drift)so Claude Code gets precise cited results instead of burning tokens on grep loops.
Built this after burning tokens and context for every new Claude thread I open. An embedding model uses a fraction of the memory a local LLM does, and gives me back what I (or Claude) are looking for instantly. It's local, offline, and now Claude can just ask the index directly. Would love to hear what you think!
