A free AI image checker that explains uncertainty
Review an image-model signal, camera metadata, and the presence of provenance markers in one place. AICheck keeps standard checks on your device and never presents a result as proof of who made an image.
Important: AI-image detectors can produce false positives and false negatives. Results are clues, not proof. Use them to decide what to verify next—not to accuse a person or clear an image as authentic.
A useful check takes three steps
The tool is quick. The careful part is reviewing the evidence around its result.
Review separate clues
See the model signal, readable metadata, and whether AICheck found certain C2PA/JUMBF marker bytes. The clues are not blended into false certainty.
Verify the source
Look for the original post, an earlier copy, edit history, and a signature-validating Content Credentials viewer before reaching a conclusion.
What AICheck checks
Each signal answers a narrow question. None answers “Who created this?” on its own.
Signals it can review
- A bundled image model's output for one image or sampled video frames
- Common camera and editing metadata that remains in the file
- The presence of some C2PA/JUMBF provenance-marker structures
- Long-form English text patterns as a separate experimental tool
Claims it cannot make
- That a low model score means an image is real or untouched
- That a high score identifies the person or tool that made it
- That a provenance marker has a valid signature or truthful claim
- That a screenshot, edit, or compressed copy preserves the original evidence
Private by default, with a clear free tier
No account is needed for standard checks.
On-device analysis
Text and the bundled image model run on your device by default. Optional web cloud analysis requires an active Pro subscription and a separate opt-in for that check.
Three media checks daily
The free tier includes three image or video checks per day. Text-pattern reviews are unlimited, though the text tool remains experimental.
Evidence-first results
AICheck tells you what the signal means, what could have affected it, and what source evidence to inspect next.
