GrapeRoot

AI coding tools re-read your entire codebase every turn. GrapeRoot fixes this. It builds an AST + dependency graph of your project locally, then injects only the relevant files (~4,000 tokens) before the AI starts thinking. No cloud, no tool-call overhead, no code leaves your machine. 60–70% token savings, measurable on real codebases. Works with Claude Code, Cursor, Codex, Gemini CLI, and GitHub Copilot. Open source, zero config, 150ms injection.
