grepai – CLI for semantic code search

grepai is a privacy-first CLI for semantic code search. It uses vector embeddings to understand code meaning, enabling natural language queries that find relevant code—even when naming conventions vary.

Drastically reduces AI agent input tokens by providing relevant context instead of raw search results.

This is free and open source software.

Features include:

• Search by intent — Ask “authentication logic” and find handleUserSession.
• Trace call graphs — Know who calls a function before you change it.
• 100% local — Your code never leaves your machine.
• Always up-to-date — File watcher keeps the index fresh automatically.
• AI agent ready — Works with Claude Code, Cursor, Windsurf out of the box.
• MCP server — Your AI agent can call grepai directly as a tool.
