semtools

A Rust-based CLI tool for semantic search across code and documents using embedding similarity. It finds code by meaning rather than keywords, supports workspace caching for performance, and can parse PDF/DOCX/PPTX files with an API key. Useful for discovering code when you don't know exact function names.
