Why clean your prompt before using AI?

AI prompts often include customer names, contact details, order numbers, URLs, account data, internal notes, and project context. Cleaning the prompt first helps reduce accidental sharing before you paste the text into ChatGPT, Gemini, Claude, or another AI tool.

FAQ

Is my text uploaded to a server?

No. The cleaner runs in your browser and does not send the text you paste to a server.

Can this tool catch every private detail?

No. It highlights possible sensitive information so you can review it. Pattern-based detection can miss items or flag harmless text.

Can I use it before ChatGPT, Gemini, or Claude?

Yes. Clean the text here first, review the result, then copy it into the AI tool you want to use.
