Frequently asked questions
- Is the AI Watermark Remover free?
- Character cleaning (paste text) and file cleaning (upload a file) are both free, no account required. Claude Rewrite -- retyping pasted text from scratch -- is a paid feature on the Pro plan.
- What file types can I clean?
- PDF, Word (.docx/.docm), Excel (.xlsx/.xlsm), PowerPoint (.pptx/.pptm), images (JPG, PNG, TIFF, WEBP), and plain text formats (.txt, .md, .html, .csv, .json) -- up to 15MB per file.
- What does character cleaning actually remove?
- Hidden Unicode characters, invisible formatting marks, and other non-printing characters that can ride along in copied or AI-generated text. That’s a finite, enumerable set, so removal is complete for that category.
- What does Claude Rewrite do differently?
- It retypes the text from scratch -- same facts, structure, and length, wording kept close to the original -- rather than deleting anything. That’s the only way to address a signal embedded in word choice itself, though it’s still not a guarantee against any specific watermarking scheme.
- Do I need an account?
- No account is needed for text or file cleaning. Claude Rewrite requires signing in and a Pro subscription.
