OpenAI image checks

ChatGPT Image Detector

Checking a picture that may have come from ChatGPT, DALL-E, Codex, or the OpenAI API? Slop or Not reads OpenAI provenance signals first, including C2PA metadata and SynthID watermarks, then checks the pixels if the proof was stripped or degraded without sending 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 OpenAI Provenance First, Then the Pixels

OpenAI C2PA Content Credentials when they survived export

OpenAI SynthID watermark signals when the image still exposes them

Visual generator artifacts after social apps strip metadata

Good Uses

  • Checking a ChatGPT image from a download folder
  • Verifying a blog or newsletter image before publishing
  • Testing a file after it has moved through chat or social apps

Limits to Know

  • OpenAI Verify is scoped to OpenAI provenance signals, not Gemini or every other generator
  • Screenshots usually remove C2PA/IPTC metadata and can reduce the strongest provenance evidence
  • A clean metadata read does not prove the pixels are human-made

FAQ

ChatGPT Image Detector Questions

Does ChatGPT add metadata to generated images?

OpenAI says images generated with ChatGPT, Codex, and the OpenAI API include both C2PA metadata and SynthID watermarks. Slop or Not checks those signals when the image still exposes them.

What happens if the metadata is gone?

Slop or Not checks for remaining watermark evidence, then falls back to visual image detection and reports a probability. A missing credential is weaker evidence, not proof that the image is real.

When should I use the broader AI image detector?

Use the ChatGPT image detector when OpenAI is the suspected source. Use the broader AI image detector when the generator is unknown or the image has passed through several apps.

Can ChatGPT detect AI images?

Not reliably. ChatGPT can describe an image, but it does not run provenance checks, and its guesses about AI origin are inconsistent. Slop or Not reads OpenAI C2PA Content Credentials and SynthID watermark signals first, then checks the pixels.

Can ChatGPT see or look at images?

Yes. You can attach images and ChatGPT will describe or analyze them. Seeing an image is not the same as verifying it: for a repeatable AI-or-not verdict, run the file through this detector, which checks provenance metadata and watermarks before judging the pixels.

SynthID Watermark Checker

Check images for SynthID watermark signals. Slop or Not checks supported OpenAI and Google/Gemini provenance, then checks pixels when signals are unclear.

C2PA Detector

Use this C2PA detector to check Content Credentials with Slop or Not. It reads signed provenance, then checks pixels when credentials are absent.

AI Watermark Detector

Use this AI watermark detector to check images for SynthID, C2PA Content Credentials, and IPTC metadata before pixel detection.
