AI watermark check
AI Watermark Detector
Use this AI watermark detector to explore watermark signals, check for broader AI-writing patterns, and understand what the result can and cannot prove.
Is there one universal AI watermark?
No. Providers may use different provenance systems, metadata, or research techniques, and ordinary pasted text may not retain a directly verifiable universal watermark.
What this AI watermark detector checks
The current checker estimates broader AI-writing patterns such as repetition, predictability, and uniform structure. It does not claim to decode a secret provider-specific watermark.
How to check for an AI watermark
Paste the text and use the result as an initial signal. If the original file includes metadata or signed provenance, inspect that evidence separately because plain-text analysis cannot recover information that disappeared during copying.
Watermark detection versus AI text detection
A watermark is an intentionally embedded signal; AI text detection infers patterns from the writing itself. The two ideas are often mixed together in search, but they are not technically equivalent.
AI Watermark Detector FAQ
Practical answers about the check, its results, and its limits.
Can this detect AI watermarks in pasted text?
It can screen pasted text for general AI-writing signals. It cannot guarantee that an official or hidden watermark exists, identify its provider, or reconstruct removed metadata.
Is the AI watermark detector free?
Yes. You can use the current free allowance to run a preliminary check without buying a plan.
Does every AI-generated text contain a watermark?
No. There is no single universal text watermark shared by every model, provider, output format, and copying workflow.
