Remove hidden Claude marks and humanize AI-generated text in one click.
Claude Mark Remover is a free online tool for cleaning and humanizing Claude-generated content. It addresses two layers of AI detection: hidden Unicode characters embedded in copied text and recognizable patterns in AI-generated wording.
The tool strips invisible characters mechanically and then rewrites sentences while preserving facts, figures, names, keywords, and the original argument. Users can paste text or upload supported documents and images for processing.
Key features include selecting a readability level, optimizing results for particular writing purposes, choosing from eight languages, enabling enhanced processing, and freezing exact keywords. Results include the cleaned draft, the number of hidden characters removed, the number of rewritten sentences, and a human-writing score.
The service offers unlimited usage with no signup required. All processing happens browser-based for privacy. It also supports removing metadata such as C2PA credentials, EXIF, and XMP from supported files.
