Witchcraft is a Rust reimplementation of Stanford's XTR-Warp semantic search engine that uses a single-file SQLite database for storage, enabling client-side deployment. The system operates completely stand-alone with no API keys or vector database required, achieving 21ms end-to-end search latency while being faster than the original XTR-WARP. An included example application called pickbrain indexes code session transcripts from AI tools like Claude Code and OpenAI Codex for fast semantic search.
