What the tool actually does
It removes verifiable invisible Unicode characters and supported file metadata. There is no guarantee for statistical watermarks hidden in wording. The tool also does not claim to bypass an official Claude detector.
The technical foundation comes from the open source project guillaumemeyer/watermarks-remover and is available under the MIT license.
