SynthCheck

What this can and cannot prove

Other detectors show a confidence percentage. Ask where the number comes from and you get no straight answer. We show the evidence instead.

Solid ground

  • Confirming AI origin when the generator labelled its own output
  • Reading signed C2PA manifests and every action recorded inside
  • Recovering prompts, seeds and model names left in the file
  • Showing camera body, lens, exposure and GPS
  • Spotting generator-preset dimensions and software encoders after metadata is gone

Out of reach

  • SynthID. Google DeepMind's watermark lives in the pixels, not the metadata, and there is no public reader. Use Google's own SynthID Detector.
  • A verdict from pixels alone. We do not run a classifier and we will not invent a percentage.
  • Certificate validation. We show you the manifest; the official verifier checks the signing chain.
  • Anything at all, sometimes. A screenshot of a screenshot carries no information, and no tool can change that.
