loci

loci indexes the project docs, notes and chat logs scattered across a dozen directories: heading-aware chunking, embeddings, hybrid retrieval (vector plus BM25), and answers with section-level citations.

Why it matters: It ships as an MCP server, so Claude Code, Codex or any MCP client can query your own material instead of asking you what was decided last month. Local files in, cited answers out.

Python 3.11+, MIT licensed, under 100 stars at the time of listing. The name comes from the memory-palace technique: place knowledge in locations, recall it by walking the path.
