Cleaning a paste that came from a chat window
A chat interface hands the clipboard two versions of your selection: styled HTML and plain text. Whichever one the destination takes, characters can survive that you never typed. Zero-width spaces sit between words. Non-breaking spaces stand in for ordinary ones. Class names ride along inside the HTML flavour.
None of that is a watermark. All of it shows up in a diff, in a CMS, or in a plagiarism report as something odd, which is reason enough to clean it.
The image side is where removal is real
Images from ChatGPT carry Content Credentials in the file. Those come off cleanly, and the export is re-scanned to confirm they are gone. The pixel watermark does not come off, and DetectMark never claims it did.
What this page will not do on its own
It will not rewrite your sentences as part of a cleanup. A humanizer is a paraphraser with marketing, and paraphrasing is the one operation that changes what a statistical detector would see. That is a decision for the writer, which is why the rewrite on this site is a separate step behind a consent dialog, shown with a receipt of what changed and no claim about what it removed.
FAQ
No. OpenAI has not deployed a text watermark. This tool removes hidden Unicode characters and clipboard fragments that can appear in AI text from any source.
Metadata yes: C2PA, EXIF and XMP all come off, and the export is re-scanned to prove it. The pixel watermark stays, and the receipt says so.
Probably not. Those classify by style, not by hidden characters.
If a paste still contains U+202F from any source, this tool flags it and replaces it with an ordinary space when you opt in. The character is not exclusive to ChatGPT and was never a watermark.
No. Zero bytes of your text leave this browser tab.
