cronos3k/Text-Stealth-Watermark-Cleaner-Detector ? reverse-engineered prompt

Build me a simple text cleaner tool that can detect and remove hidden watermarks from AI generated text.

I want to paste in or upload a text file, then have it scan for invisible Unicode characters, odd whitespace, control characters, and lookalike Unicode letters, then clean the text and show me what changed. Please also generate a clear report that lists the problems it found, with counts and the exact character details, and save that report in both a human readable format and a JSON format. The cleaned text should be exported separately too.

Keep it lightweight and easy to run with no extra dependencies if possible, and make the interface straightforward enough that a normal person could use it without learning technical stuff. If you think a small web page is the easiest way to interact with it, make that work too. Look up current docs online if you need to.
