How to Remove the Claude Watermark (Does It Actually Work?)

A Claude watermark remover has passed 12,000 stars on GitHub—but does it actually work?

I test the tool, explain how Claude’s text watermark works, show how to install the remover without being technical, and cover the crucial limitation: nobody can verify the result against Anthropic’s detector because that detector is not public yet.
