Reference

About

Reference provides semantic search for your files and code on your local machine, designed specifically for AI agents. Everything remains on your computer, with no data sent to the cloud. You can ask questions like "how did I implement rate limiting here" and receive your exact code back, pinpointed to the specific function rather than general suggestions. It features a live index that updates automatically as you save files, along with code-aware chunking powered by tree-sitter. A built-in MCP server offers endpoints such as /search, /explain, /find_similar, and /check_doc_drift, enabling Claude Code to obtain accurate, cited results without wasting tokens on repetitive grep operations.
