How to remove Claude's watermark from Notion
To remove Claude's watermark from a Notion page, rewrite the text through a non-watermarking model, since Notion stores your words verbatim and the watermark is carried in those words. Pasting Claude output into a block keeps the watermark intact.
What Notion does with Claude's watermark
Notion preserves pasted text, including invisible characters, and does not apply or strip any AI watermark. Whether a page is private, shared, or published to the web, the statistical watermark stays in the copy until the wording is changed.
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 your Notion block. Use Cmd/Ctrl+Shift+V for plain-text paste to drop hidden styling.
- 3For pages already written with AI, select all, copy out, clean, and paste back.
- 4Publish or share the page — the version others see carries the cleaned text.
FAQ
Does publishing a Notion page strip the watermark?
No. Notion publishes the exact text, so the statistical watermark is included. Clean the wording first.
Is a private Notion page safe?
The watermark is present whether the page is private or public. It only matters when the text leaves Notion or the page is shared, but cleaning early avoids surprises.
Remember: Claude's watermark is statistical — it lives in the word choices, so it travels with your text into Notion 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 →
