¿Qué es Claude Watermark?
Claude Watermark is a web tool for inspecting pasted AI text for detectable artifacts and removing them. Its core focus is on the practical traces that copy-paste can leave behind, such as hidden HTML class names, invisible Unicode characters, and punctuation patterns that may make text look machine-generated.
The product divides the workflow into a free browser-based check and a credit-based cleaning step. The checker reports concrete findings with counts and positions, while the cleaner rewrites text to remove those artifacts and adjust sentence structure for a more natural read.
¿Qué puede hacer Claude Watermark?
Exact artifact reporting
The checker returns counts and positions for detected items, making the output easy to verify directly in the text.
HTML class cleanup
The cleaner removes Claude-related class names that can survive a rich-text paste, including class attributes containing "claude".
Invisible character detection
It identifies zero-width characters, byte-order marks, and non-breaking or exotic spaces that are not obvious on screen but remain in the bytes.
Rewrite pass for readability
After artifact removal, the rewrite step changes sentence rhythm, length, and phrasing to reduce machine-like surface patterns.
Automatic credit refunds
If a rewrite job fails, the pricing page says credits are returned automatically without needing a support request.
Casos de uso
“Sanity-checking a pasted draft”
Writers can paste text into the checker before sharing it to see whether the paste introduced hidden markup or invisible characters.
“Cleaning AO3 posts”
The site explains that AO3 preserves pasted HTML, so users can remove Claude-related class names before publishing a work.
“Tidying Google Docs content”
For Google Docs, the tool can help identify markup carried over from a paste and complements paste-without-formatting or clear-formatting workflows.
“Preparing AI-assisted text for review”
If a draft needs a more human-sounding pass, the cleaner can rewrite the passage after the structural artifacts are removed.
“Checking content in other editors and publishing tools”
The site references workflows for platforms such as WordPress, Notion, Substack, Medium, Microsoft Word, Gmail, and others that may keep pasted formatting.
Preguntas frecuentes
What does Claude Watermark remove?
It removes detectable paste artifacts such as Claude-related HTML class names, zero-width characters, byte-order marks, non-breaking and exotic spaces, and certain punctuation and rhythm signals that can make text look machine-generated.
Is the checker free to use?
Yes. The site says checking is free, unlimited, and does not require an account.
Does checking upload my text?
No. The site says the check runs in your browser, so the text is not uploaded for that step.
Can it confirm Anthropic’s hidden watermark?
No. The site says Anthropic’s statistical watermark cannot currently be confirmed by outside tools because the key needed to verify it has not been published.
How are cleaning jobs billed?
Cleaning and rewriting use credits. The pricing page says new users get 3 free credits with no card, and credits never expire.
