AI Image and Video Detectors by Generator

Pick the generator you suspect, from ChatGPT and Midjourney to Sora and Veo, and see which provenance signals it leaves, how to check them and where checks end.

AI generators differ in what they leave behind. Some, such as Adobe Firefly and ChatGPT, attach C2PA Content Credentials to the files they export. Google's tools embed an invisible SynthID watermark. Stable Diffusion interfaces often write generation parameters into PNG files. Other generators document no provenance signal at all. Each page below covers one generator: the signals its maker documents, how to check them, and what a missing signal does and does not mean.

Start with the generator someone says made the image, or the one you suspect. If you do not know, the free checker reads Content Credentials and AI metadata in your browser without uploading the file, and the step-by-step guide covers checks that work for any image.

A generator page is not a verdict. Screenshots and re-uploads can strip provenance, and visual clues are unreliable on their own, so treat every result as one piece of evidence and ask for the original file when the answer matters.

Check by AI video generator

  • Sora AI Detector: Watermark and C2PA Check

    How to tell if a video was made with OpenAI's Sora: the visible Sora watermark, C2PA Content Credentials, what re-encoding and cropping hide, and what to ask next.

  • Veo 3 AI Video Detector: SynthID Check

    How to check if a video was made with Google Veo: verify SynthID in the Gemini app, look for a visible Veo mark, and read a “not detected” result with care.

A file report is one clue. Review its evidence and limitations.
