Rewriting, measured

Substitutes vocabulary at an intensity you control and reports the percentage of wording changed along with a similarity score against the original.

A substantial rewrite is the only approach that genuinely disrupts a statistical watermark, because the mark is carried by the sequence of word choices. This is a local, dictionary-based rewrite and it is weaker than sending text through a non-Claude model, which is what the open-source removal tools do.
