AI Image Detector: Check If a Photo Is AI-Generated

Want to tell if an image is AI-generated but do not know which tool made it? Use this AI image detector for unknown-source checks. Slop or Not layers SynthID watermark reads, signed Content Credentials/C2PA, editable IPTC metadata, and visual AI traces without passing online uploads to outside AI companies.

  • You can testPhotos, screenshots, product images, receipts, and profile pictures up to 8 MB.
  • ResultA probability verdict, AI score, and source details when the file carries them.
  • PrivacyDeleted the moment the check finishes. We never keep your photo.

AI detection is probabilistic. Results can vary with new AI models and evasion methods. A real photo edited with AI tools can be flagged as AI.

Online checks are deleted after processing.

What it checks

Check Unknown-Source AI Images Across Provenance and Pixels

SynthID watermark checks for supported OpenAI and Google/Gemini images

C2PA Content Credentials and IPTC metadata when the file carries them

Image classifier output when provenance is stripped or inconclusive

Good Uses

  • Checking profile photos before trusting an account
  • Reviewing product images before publishing or buying
  • Screening AI-looking images when the source model is unknown

Limits to Know

  • Official provider verifiers are not universal checks for every SynthID signal
  • Screenshots can remove C2PA/IPTC metadata, while heavy edits can weaken watermark signals
  • The result is a probability unless a readable watermark or signed credential is present

FAQ

AI Image Detector Questions

Is this also an AI photo detector?

Yes. Photo, picture, and image searches all use the same Slop or Not workflow: check the file for AI provenance clues, then read visual generator signals when the file has no readable watermark or metadata.

Does the online checker run on-device?

No. Online checks run on a private Mac server, are deleted after processing, and are not shared with third-party AI providers. The iPhone and Mac apps run detection on-device.

Can it prove an image is human-made?

No AI detector can prove human authorship in every case. Missing provenance is not a clean bill of authenticity, so Slop or Not reports evidence and probability for human review.
