About Unmark
Unmark is a free web-based tool designed to remove digital watermarks from AI-generated text. As major AI providers increasingly watermark their outputs by default—such as Google's SynthID and Anthropic's Claude (to comply with the EU AI Act)—Unmark provides an easy way to strip these identifiers and restore clean text.
The tool tackles watermarking using a two-pronged approach. First, it instantly strips invisible Unicode characters (such as zero-width spaces, joiners, tag characters, and homoglyphs) directly within your browser. Second, it rewrites the wording of the text to actively disrupt statistical or SynthID-style watermarks. Unmark is completely free to use and operates entirely without requiring a login or account creation.
Pros of Unmark
- Removes both invisible Unicode characters and statistical AI watermarks
- Works instantly in your web browser
- Completely free to use with no hidden fees
- No registration, sign-up, or login required
Cons of Unmark
- Disrupting statistical watermarks requires rewriting the text, which alters your original wording
- Specifically targeted at SynthID and Claude watermarks, with no mention of support for other proprietary watermarking systems
Frequently Asked Questions
