AI Video Detector — Spot Synthetic Video
Check whether a video was generated by AI tools like Sora or Runway. CheckAI samples key frames and analyzes them for the signs of synthetic, AI-generated footage.
An AI video detector checks whether footage was generated by tools like Sora or Runway by analyzing its frames. CheckAI samples key frames and estimates how likely the clip is to be synthetic — free to start with 20 checks daily, alongside AI text and image detection.
How to detect AI video in 3 steps
Provide the video frames
Add key frames from the clip you want to check. CheckAI analyzes up to three frames per request.
Analyze for AI signals
CheckAI reviews the frames for the artifacts typical of AI-generated video.
Get a clear verdict
See how likely the footage is to be synthetic before you trust, publish, or share it.
Review footage for AI generation
Frame-level analysis for the era of Sora-class video.
Detects AI-generated video
Flags frames consistent with tools like Sora, Runway, and other generative video models.
Frame-level analysis
Samples multiple frames so the verdict is based on more than a single still.
One detection suite
Check text, images, and video in the same account, with the same credits.
Private by default
Your footage is never stored or used for training.
How does AI video detection work?
AI-generated video carries frame-level artifacts — in motion, texture, lighting, and fine detail — that differ from real footage. CheckAI samples key frames from a clip and analyzes them for those signals, then estimates how likely the video is to be synthetic. Sampling several frames makes the result more reliable than judging from a single still.
Why AI video detection matters now
Tools like Sora and Runway can produce convincing video from a text prompt, which raises the stakes for provenance and trust. Before you republish a clip, rely on it as evidence, or share it widely, a quick frame check helps you avoid passing on synthetic footage unknowingly.
Text, image, and video in one place
CheckAI is a single detection suite. The same account and credits cover AI text detection, AI image detection, and AI video detection — so you can verify any kind of content without juggling separate tools.
AI video detector FAQ
Can it detect Sora and Runway videos?+
CheckAI analyzes video frames for the signals of AI generation, including footage from tools like Sora and Runway. As generators improve, results are best read as a strong signal rather than absolute proof.
How many frames does it analyze?+
Up to three frames per request by default, which gives a more reliable read than a single still.
Is the AI video detector free?+
Yes. Every account gets 20 free credits daily with no credit card required.
Are my videos stored?+
No. Your footage is never stored or used for training.
Check whether a video is AI-generated
Frame-level AI video detection, free to start. 20 credits daily, no card required.
