Detect and remove hidden AI watermarks from text and files in seconds.

I built an AI watermark remove and before you claim BS Read This I built an AI watermark remover called un-claude.com . Before you claim BS, I suggest you read this. I approached this from a very technical perspective and am transparent about my absolute claims in terms of what we can and can't positively guarantee. There are 3 kinds of AI watermark, and we can only positively claim we remove two of them. 1) Invisible characters - (Zero-width spaces, joiners, direction marks) We name

Plenty of redaction tools upload your file to their server first (no thanks for legal/medical/tax docs). Some keep the file local but send the text off to an AI, so the text still leaves. And most of the truly local ones only let you draw black boxes by hand, which is how those "redacted" documents in the news keep getting un-r
