How to remove Claude's watermark from Medium
To publish a Claude-drafted article on Medium without the watermark, rewrite the text through a non-watermarking model first, because Medium stores and serves your exact words. The watermark is in those words, so it publishes to every reader unless broken.
What Medium does with Claude's watermark
Medium preserves pasted text and publishes public, indexable articles. It does not add or remove a watermark. Cleaning before publishing keeps a permanent public post from carrying provable AI provenance.
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 the Medium editor. Paste as plain text to avoid importing hidden characters.
- 3Confirm formatting and images render, then publish.
FAQ
Does Medium detect AI writing?
Medium does not run watermark detection. The concern is future third-party or Anthropic detection on your public post, which cleaning avoids.
Remember: Claude's watermark is statistical — it lives in the word choices, so it travels with your text into Medium 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 →
