Local search over your code and documents for AI agents.
Coding agents make up quotes from PDFs and Office files they cannot open. Semlith is a free, open-source local index of your code and docs that Claude Code, Cursor and Codex search over MCP. In my test, made-up quotes went from 41 of 127 to 0.
Semlith is an open-source local indexing tool that enables AI coding agents to accurately search through code and documents, reducing reliance on fabricated quotes. It integrates with AI platforms like Claude Code, Cursor, and Codex to enhance search accuracy for developers.
A source that found nothing is a measurement. A source that has not run is a gap. Neither means the launch lacks the thing.
