Local semantic search for AI agents
Reference is a powerful local semantic search tool designed specifically for AI agents and developers working with code and files. Unlike cloud-based solutions, it runs entirely on your machine, ensuring data privacy and security. Its core feature set includes a live, continuously updating index that intelligently chunks code using tree-sitter, enabling precise and context-aware searches. Users can ask complex questions like 'how did I implement rate limiting here?' and receive exact code snippets cited down to the specific function, significantly improving debugging and code comprehension. The built-in MCP server offers endpoints such as /search, /explain, /find_similar, and /check_doc_drift, allowing AI models like Claude Code to generate accurate, citation-based results without wasting tokens on inefficient grep loops. Suitable for developers, AI engineers, and teams prioritizing privacy and precision, Reference elevates code search from simple keyword matching to an intelligent, code-aware experience.
