How to tell if a video is from Sora
Videos downloaded from Sora carry Content Credentials identifying them as AI-generated by OpenAI, and usually a moving Sora watermark. We read the credentials from the file and check three frames with our AI detectors. If the clip was re-uploaded (TikTok, Reels, X), the credentials are usually stripped, so the frames decide.
- Look for the Sora logo drifting around the frame — or blurry patches where it was removed.
- Watch hands, text and faces across the clip for subtle morphing.
- Check physics: splashes, collisions, crowds and reflections.
Frequently asked questions
Does this work for Sora 2?
Yes — Sora 2 downloads include Content Credentials, which we read. Frame analysis covers copies without them.
Can it detect Veo, Kling or Runway videos?
Yes, the same check works for other AI video tools. See the AI video detector.
Is IsItMadeByAI really free?
Yes. Every scan is free, there is no sign-up, no credit card and no watermark on your results. The site runs on open-source detection models, which is how we keep it free.
