Claude Watermark

I built this after the Anthropic watermarking news broke and I noticed that almost every tool ranking for "Claude watermark remover" was solving a different problem. Anthropic's mark is distributional — a keyed bias on token selection — so the signal is the word choice itself. Stripping zero-width Unicode, which is what most of those tools do, cannot touch it. So I wrote the honest version. Two things I'll say against my own interest: no shipped Claude model carries the mark yet (it applies to models launched on or after 2 Aug 2026, and nothing qualifies), and Anthropic hasn't published a detector, so nobody outside Anthropic can verify a passage is marked — which means nobody can verify a removal worked either, including me. What the tool does do is real: it finds the artifacts that actually give AI-assisted text away — the HTML classes Claude's web UI leaves in your clipboard, zero-width characters, exotic spaces, smart punctuation — and rewrites the passage so it reads like you. Happy to go into the tournament-sampling detail if anyone's curious.

shipped it very fast

The [specific feature] is interesting because [reason]. One thing I'd like to know is whether [specific question]. This could be particularly useful for [specific use case].

I tink is useful just to start brainstorming

Looks very helpfull to me

for me,it works well

The distinction between actual distributional watermarking and copy-paste artifacts is unusually clear. A before/after diff that separates invisible Unicode cleanup from the human-rewrite pass would make the result easier to audit, especially for citations and technical wording. Can users accept each change selectively?

The honest framing is refreshing — most "watermark remover" tools overpromise and this one correctly separates copy-paste artifacts from the distributional watermark that isn't even shipped yet. The artifact detection alone (HTML classes, zero-width chars, smart punctuation) covers the real problem people actually hit when pasting from Claude's web UI. One suggestion: a before/after diff view showing exactly what was rewritten (invisible char cleanup vs. reworded passages) would make the output auditable, which matters for anyone using it for academic or professional work.

I see the potential in this product, good job!

such a L move from anthropic

this was such an odd move. even google says it doesn't care about AI content if it is useful.

Kinda love how simple this is lol. Just paste your Claude text in and it cleans up all the weird hidden stuff for you. Super specific tool, but honestly pretty useful if you use Claude a lot.

loved this product. makes working easier

Love it very much. And it's very useful.

Interesting idea, especially with AI-generated text becoming so common. It’d be helpful to explain what each detected artifact means and how confident the result is, rather than just flagging it.

brilliant idea you have out there. curious if anyone have used this and have real experience sharing

Helpful tool. Especially that it's trained on replacing em dashes which LLM's like to use extensively.
