Why ChatGPT text has hidden characters
Chat apps render answers as rich text. When you copy it, invisible Unicode characters can come along: non-breaking spaces, narrow spaces around punctuation, zero-width joiners and more. You can't see them, but spell checkers, code compilers, CMS editors and form validators can.
What problems they cause
Code that won't run because of a stray non-breaking space, headings that won't align in Word, search-and-replace that misses words, and odd line breaks in email. Cleaning the text fixes all of it.

Questions
Does ChatGPT put a hidden watermark in its text?+
OpenAI has said it does not add a secret watermark to ChatGPT text. What people usually find are invisible Unicode characters such as zero-width spaces, non-breaking spaces and directional marks. They come from formatting and copy-paste, and they can break code, mess up spacing in Word and cause odd behaviour in forms. This tool finds and removes them.
Will this make my text pass an AI detector?+
No, and we don't claim it will. AI detectors judge writing style, not invisible characters. This tool fixes formatting junk so your text behaves properly wherever you paste it. If you want text that reads like you, edit it in your own voice.
Is my text sent to a server?+
No. Cleaning runs in your browser with JavaScript. Nothing you paste is uploaded, logged or stored.
What exactly gets removed?+
Zero-width spaces and joiners, byte order marks, left-to-right and right-to-left marks, invisible tag characters, soft hyphens, control characters and unusual spaces. Optional extras convert curly quotes, em dashes and ellipses, strip Markdown symbols and tidy whitespace.
Does it work with Claude, Gemini and Copilot text?+
Yes. It works on any text, whatever tool or website it came from.
