Add anything you want kept. We use it as a guide (it does not change how the text is rewritten).
Ask how to take the rewrite further, like "make this paragraph shorter" or "is this phrasing too stiff?". Each exchange uses coins for what it actually costs.
Turn this off and nothing is kept once the rewrite returns. Anything already stored is deleted at the same time.
Use this key to let AI tools that accept a server URL and key, such as Claude Code, Cursor, or VS Code, use MUKU. With it, the AI can rewrite text, check your balance, and view your history. It can't sign in or delete your account. Connect to https://muku-inkshield.com/mcp. The Claude and ChatGPT apps don't use a key: add the server URL and MUKU's sign-in and approval screen opens.
This key is shown only once. Copy it into your AI's settings.
Apps such as Claude or ChatGPT that you've connected to MUKU and approved. Disconnect one and it can no longer use MUKU.
