Tennis is a local-first CLI context store that indexes files and AI chat histories into SQLite with hybrid BM25 + semantic search using a static embedding table (potion-retrieval-32M), enabling fully offline retrieval. It fuses keyword and semantic results, writes human-readable markdown 'cards', and offers a Go library and local HTTP API. Interesting for privacy-conscious users wanting a personal RAG-style knowledge base without cloud dependencies.

Target audience: developers, power users, privacy-focused individuals
