Metadata checks

Image Metadata Checker for AI Provenance

Use this IPTC metadata detector to read editable image fields that can disclose creator, source, or AI use. Slop or Not weighs those clues against signed credentials, then scores the pixels with a classifier trained on millions of human and AI images when no readable provenance or watermark resolves the file. Online checks stay away from outside AI companies.

A SynthID checker finds stamped images. Slop or Not also checks the ones nobody stamped.

It reads SynthID from Google and OpenAI images, verifies C2PA Content Credentials, reads generator fingerprints, and scans the pixels.

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.

  • 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.
  • PrivacyChecked on hardware we own and run. We never pass your photo to OpenAI, Google, or any other AI company.

What it checks

Read IPTC Disclosure Fields, Then Compare C2PA Evidence

Readable IPTC fields that name source, creator, or AI disclosure

Adjacent EXIF or app metadata left by editing tools

Fallback image detection when metadata is missing or empty

Good Uses

  • Checking image metadata before publication
  • Reviewing asset libraries for AI disclosure fields
  • Comparing metadata evidence with visual detector output

Limits to Know

  • Metadata can be edited, removed, or replaced
  • IPTC fields are weaker evidence than signed C2PA credentials
  • A clean metadata panel does not prove a human made the image

FAQ

IPTC Metadata Detector Questions

Is IPTC metadata signed?

Not usually. IPTC metadata is editable image metadata used by publishing and asset tools. It is useful context, but signed C2PA credentials are stronger evidence when available.

Can metadata be faked?

Yes. IPTC metadata can be edited, removed, or replaced. Treat it as evidence, not a final ruling. Slop or Not pairs it with image detection.

Why have a separate IPTC page?

IPTC metadata is common in publishing workflows and asset libraries, where teams may add creator, source, and AI disclosure fields. C2PA is stronger when signed provenance is available.
