FAQ from Claude Mark Remover
What kinds of marks does Claude Mark Remover handle?
- It addresses both layers of Claude output marking: invisible Unicode characters such as narrow no-break spaces and zero-width joiners are stripped mechanically, while the statistical signal embedded in word choices is broken by genuinely rewriting each sentence.
Does the tool change the visible content of the text?
- The character-stripping step leaves every visible word untouched. The rewrite step rebuilds sentence structure so the watermark pattern no longer holds, while the tool reports a human score so users can review the result.
Is any text or file stored on a server?
- No. All processing runs locally in the browser, nothing is uploaded or retained, and there is no account requirement.
Are there limits on length, file size, or usage?
- Text processing has no length limit and is free and unlimited. File metadata cleaning supports files up to 20 MB across common image and document formats.
Which Claude models produce watermarked output?
- Claude Opus 4.5, Sonnet 4.5, and Haiku 4.5 are marked at the model level under the EU AI Act transparency commitment, older models such as Claude 3.7 Sonnet are in transition, and Claude 3.5 Sonnet predates native watermarking.
Can it also clean files, not just pasted text?
- Yes. Images and documents carry C2PA content credentials in their metadata rather than in the wording, and the tool strips these credentials together with EXIF and XMP data.
