I pasted a chunk of Claude output straight from the chat window and it flagged a handful of zero-width characters and a couple of leftover span classes I never would have noticed just eyeballing the text. One click and it was clean. Runs entirely in the browser, no account needed, and it's honest that it's checking for literal copy-paste artifacts rather than claiming to detect some invisible statistical watermark - that distinction actually matters and most "AI detector" tools blur it on purpose.
thank u, and the batch mode feedback is fair. drag and drop for multiple files would be really useful while still keeping everything local. appreciate the detailed review :)
