Stop paying for tokens your AI already has.
Prompt Genie is a token saver for the AI tools you already use. In AI agents like Claude Code, Codex, Gemini CLI and GitHub Copilot CLI, Lean serves repeat file reads from session memory instead of sending and billing them again.
In ChatGPT, Claude and Gemini, the free Chrome extension trims what you paste, cuts padded replies and sharpens your prompt before it reaches the AI, so you get the answer you wanted on the first try.
Install for your AI agent with npx prompt-genie, or add the Chrome extension and start free.
