Clean AI Text & Strip Hidden ChatGPT Formatting
Paste text from ChatGPT, Claude, or Gemini to instantly clean AI formatting, normalize em-dashes, and strip invisible characters — 100% private in your browser.
Why clean AI text
AI tools leave more behind than words
Text copied from ChatGPT, Claude, Gemini, and other AI tools often carries hidden characters, smart quotes, em dashes, and leftover Markdown syntax that were never meant to leave the chat window.
These artifacts break things downstream
They can break search and find-and-replace, cause formatting problems when pasted into another document, and make plain text behave unpredictably.
Cleaning removes the quirks
The result reads and behaves like text you typed yourself.
What makes this different
Built to be trustworthy, not just functional.
100% browser-based
Your text is cleaned directly in your browser. Nothing is uploaded, stored, or sent to a server.
No signup required
Paste, clean, and copy immediately. No account, no email.
Transparent by default
See exactly what was changed, and how many issues were found, every time you clean.
Free to use
No paywall and no usage limits.
