Frequently asked questions about Claude Watermark Remover
What does it actually detect?
HTML class names containing 'claude', zero-width spaces, byte-order marks, non-breaking spaces, em dashes, and curly quotes. It cannot verify the statistical watermark without Anthropic's key.
Is my text uploaded or stored?
No. All checking runs in your browser locally. Nothing is uploaded or stored.
Can it remove all watermarks?
It can remove HTML artifacts and invisible characters in one click. The statistical watermark can only be addressed through rewriting.
How reliable are the stylistic findings?
Treat them as context only. Em dashes and curly quotes appear across legitimate human writing at rates from 0 to 26 per thousand words, so they cannot accuse anyone on their own.
