Claude Watermarks Remover

Paste Markdown that looks clean but still carries invisible Unicode. The tool strips those carriers, rewrites the prose, and lets you copy Markdown, raw text, or HTML. 850 characters free after verification; 5,000 with an active Gehirn plan.

How it works

Two passes, then the format you need

Visible words are not the whole document. A zero-width space or a right-to-left override can sit between ordinary letters and never show up in a preview. This tool treats that hidden layer first, then rewrites what remains.

  • Strip hidden carriers

    AI-generated text often ships with invisible Unicode: zero-width spaces, bidi overrides, variation selectors, and private-use characters. Those marks survive a normal copy-paste and can fingerprint the draft. This pass removes them and normalizes exotic spaces, while keeping real emoji, Arabic and Indic joiners, and other legitimate script glue.

  • Rewrite the visible prose

    Hidden-character cleanup is not enough for statistical watermarks. A second pass rewrites the Markdown so sentence rhythm and word choice change, while headings, lists, links, quotes, and code stay in place. The rewrite is best-effort. It can change nuance, and the new text may itself carry an AI watermark.

  • Copy Markdown, raw, or HTML

    One rewrite, three exports. Markdown keeps the structure you pasted. Raw is the same content as readable plain text. HTML is a safe conversion for editors that expect markup — raw HTML in the source is escaped, and remote images are stripped.

Limits

What it will and will not do

The free tier is 850 Unicode characters and always asks for a captcha. That keeps the rewrite cheap enough to offer without an account. Sign in on an active Ion, Synapse, Kortex, Gehirn, or legacy plan to raise the cap to 5,000 and skip verification. Trials and canceled or past-due subscriptions stay on the free tier.

We do not cache pasted drafts, write them to the job board, or send them to Langfuse. The only copy that leaves the browser is the request to Anthropic. Do not use this to impersonate a human author, hide required AI disclosure, or submit work that another platform forbids.

FAQ

Common questions

What does Claude Watermarks Remover do?
It first deletes hidden Unicode carriers from pasted Markdown, then rewrites the visible text. You copy the result as Markdown, raw text, or HTML.
Is it free?
Yes. Anyone can rewrite 850 characters after verification. An active Gehirn subscription on any plan unlocks 5,000 characters and skips the captcha.
Does this guarantee watermark removal?
No. The Unicode pass is deterministic. The rewrite is best-effort and cannot prove a statistical watermark is gone. The rewritten text may itself carry an AI watermark. This is not a detector bypass.
Where does the text go?
Pasted text is sent to Anthropic for the rewrite. We do not store the input or the output. Anthropic may retain API traffic for a limited period under its terms. Do not paste secrets, medical, or legal source material.
