Free AI Watermark Removal Tool
Human Writes removes AI watermarks when you scan or humanize. Paste Claude or ChatGPT text on the homepage to strip invisible Unicode marks and rewrite statistical watermarks into natural voice.
Human Writes removes AI watermarks
Since Anthropic began embedding watermarks in Claude text (August 2026), more pasted AI drafts carry invisible marks. Continue to Human Writes to paste your text: we remove invisible Unicode watermarks and remove statistical Claude watermarks when you humanize, then show a built-in AI score.
Why remove AI watermarks from Claude and ChatGPT text?
When you copy from ChatGPT, Claude, Gemini, or other AI tools, invisible Unicode characters can ride along with the visible words. Since August 2026, new Claude models also embed statistical watermarks woven into word choice. Neither type shows on screen, but both can trip integrity scanners, break formatting, or fingerprint your draft back to the model.
Human Writes removes AI watermarks: invisible Unicode marks on every scan and humanize pass, and statistical Claude watermarks when you humanize the draft into natural voice. Paste on the homepage, review the built-in AI score, and copy clean output.

What kinds of watermarks Human Writes removes
AI systems hide two broadly different kinds of watermark. Human Writes removes both: invisible Unicode characters on every scan/humanize pass, and statistical watermarks (including Claude token-level marks) when you humanize the draft into natural voice.
Invisible Unicode watermarks
These are real characters inserted between visible letters that don't render on screen. They travel with copy-paste into Word, Google Docs, and CMS fields. Human Writes removes them on every scan and humanize pass:
- Zero-width space (U+200B)
- Zero-width non-joiner (U+200C) and zero-width joiner (U+200D)
- Word joiner (U+2060)
- Soft hyphen (U+00AD)
- Variation selectors (U+FE00 - U+FE0F)
- Left-to-right and right-to-left marks (U+200E / U+200F)
- Byte order mark / ZWNBSP (U+FEFF)
- Other non-printing formatting characters commonly used as covert channels
Statistical (cryptographic) watermarks
These are patterns in which words the model chooses. They are imperceptible in any one sentence and only emerge over many words. A Unicode scan cannot remove them — to neutralise a statistical watermark you typically need to lightly rewrite the text. Our guide to natural AI writing techniques covers how to do this without losing meaning.
