ChatGPT checks
ChatGPT watermark detector
Check ChatGPT-related AI-writing, provenance, and watermark support signals without claiming definitive authorship proof.
Run a signal check
No detector model loads until you press Check.
Current support
Public ChatGPT watermark detection depends on the generation path and available verification signals; AI Detect reports what is observable.
What this checks
- The checker records ChatGPT as a claimed model context when supplied.
- Text risk signals are reported separately from watermark availability.
- Saved reports keep detector results and limitations without storing submitted text.
What this does not prove
- A missing watermark signal does not rule out ChatGPT usage.
- ChatGPT text can be edited or paraphrased after generation.
- Legacy detectors should not be treated as ChatGPT-specific proof.
FAQ
- Can this prove whether content was written by AI?
No. AI Detect reports signals such as provenance metadata, watermark support status, and statistical text risk. It does not claim legal or authorship proof.
- Does text leave my browser during a local check?
Browser-default checks run local text features and provenance checks after you press Check. Server enhanced checks are separate and will be labelled before use.
- Why can a result be unknown?
Many providers do not expose public watermark detectors, and metadata can be absent or stripped. Unknown is a valid result when no reliable public signal exists.
Workflow upgrade
Need repeatable reviews?
Move from one-off checks to saved reports, batch review, and API-ready signal records when the workflow needs it.
