How to remove Claude's watermark from Microsoft Word
To remove Claude's watermark from a Word document, rewrite the text through a non-watermarking model, because Word stores your exact words and the watermark lives in those words. Save-as and re-formatting do not touch it.
What Microsoft Word does with Claude's watermark
Word preserves pasted text including invisible characters, and .docx files can also carry document metadata separate from the watermark. For anything you send externally — a contract, a report, a brief — cleaning the text and stripping stale metadata are both worth doing.
Steps to clean it
- 1Paste your Claude text into ClaudeRewrite. It rewrites the wording through a non-watermarking model (DeepSeek V4 Flash), breaking the statistical pattern while preserving every fact, number, name and link, then strips any leftover invisible characters.
- 2Paste the cleaned text into Word using Keep Text Only to drop hidden styling and characters.
- 3Before sending externally, use File → Info → Check for Issues → Inspect Document to remove document metadata (author, edit history).
- 4Save and send — the recipient's copy carries the cleaned text.
FAQ
Does saving as a new .docx remove the watermark?
No. Save-as copies the same words, so the statistical watermark carries over. Rewrite the text to break it.
What about the 'Made with Claude' image tag?
If your document contains Claude-generated images, those carry C2PA metadata. ClaudeRewrite's image tool strips that separately.
Remember: Claude's watermark is statistical — it lives in the word choices, so it travels with your text into Microsoft Word no matter how you paste. There is no public detector today, but published text stays checkable once Anthropic's detection API ships. See which models are marked →
