What is Cleanpaste?

Cleanpaste (cleanpaste.org) is a free online text-cleaning tool that removes invisible characters, zero-width spaces, hidden metadata, and statistical watermarks from AI-generated text. You paste content into the browser interface and click clean—the tool scans for hidden code points and formatting artifacts, strips them out, and returns text that reads naturally while preserving punctuation, grammar, and meaning. It requires no sign-up, has no usage limits, and processes text instantly. A separate privacy-focused Chrome extension performs similar cleaning locally on your device.
