Free AI Video Detector
Is this video AI? Upload a clip to this free AI video detector and get a score in seconds. No account needed, and your video is never stored.
How to check a video for AI
- Save the video as an MP4 or MOV file on your phone or computer.
- Choose the file above. The checker selects a short clip near the middle for analysis.
- Read the AI score, then compare with the original upload.
How the AI video detector works
Choose an MP4 or MOV file and the detector looks for signals associated with AI video generators such as Sora, Veo, and Kling. You get back a 0-100% confidence score with a green, yellow, or red result. The score is the highest AI score among the sampled frames in the selected clip. Audio is not part of this check.
Your video passes through our server to the detection engine and back. It is never written to storage, never logged, and never used for anything else.
Reading your result
A higher score means the detector found more signals associated with AI-generated video; a lower score means the video looks more like camera footage. Edited videos can mix real and generated footage, so treat the score as one signal rather than proof. Read what detector scores really mean before relying on a result.
How to tell if a video is AI-generated
Before you run a check, watch the clip closely. Current video generators are good at a single frame and weaker at keeping things consistent over time, so most giveaways appear in motion.
- Objects that change or vanish. Watch something pass behind a person or a pole. In generated video, cups, signs, and jewelry often change shape or disappear when they come back into view.
- Physics that feels off. Water, hair, and fabric move too smoothly or in slow, floaty arcs. Feet slide across the ground and hands pass through objects.
- Faces and hands in motion. Look for teeth that shift between frames, blinking that looks mechanical, and fingers that merge when a hand turns.
- Text and background people. Signs and labels warp from frame to frame, and people in the background walk in loops or melt into each other.
- Audio that does not match. Lip movement that drifts from the words and room sound that does not fit the space are both warning signs.
- Watermarks and provenance. Sora and the Gemini app add a visible watermark to generated videos, and Google also embeds an invisible SynthID mark. Watermarks are easy to crop out, so a missing one proves little.
If the clip passes a close look but still feels wrong, upload it above. The detector checks frame-level signals you cannot see, and the score tells you whether to dig further. Tracing the video back to its first upload is still the strongest check, so search for the earliest post before you share it. Our full guide to telling if a video is AI-generated walks through each check.

Free AI video detector questions
Are videos uploaded to the AI video checker stored?
No. Your video is held in memory while the request is processed, sent to the detection provider for analysis, and then discarded. It is not written to site storage or logs.
What does the score mean?
The score shows how likely the video is to be AI-generated, from 0 to 100%. A high score means the detector found strong signals associated with AI video generators. No detector is certain, so treat the result as one signal among several.
Which videos can I check?
MP4 and MOV files, including videos recorded on iPhone and Android and clips downloaded from AI video generators. Heavily compressed re-uploads from social media can hide useful signals, so use the original file when you can.
How can I tell if a video is AI without a tool?
Watch for objects that change or disappear between frames, floaty physics, hands and teeth that shift as they move, warped text, and audio that drifts from lip movement. Then trace the clip to its first upload. A detector score helps when the video passes a close look.
Can it detect Sora, Veo, and Kling videos?
The detector looks for signals associated with current AI video generators, including Sora, Veo, and Kling. No detector catches every video, and results are strongest on the original file; re-encoded social media copies can weaken the signal.
Does the checker analyze the whole video?
The checker analyzes a short clip selected near the middle of your video. It samples frames and returns the highest AI score among those frames. Audio is not analyzed.
Can I check a YouTube, TikTok, or Instagram video link?
Upload an MP4 or MOV file saved on your device. The checker does not accept page links. If you have the original video file, use that version for the clearest frames.
How many videos can I check for free?
One video per week. The AI Detector app on iPhone and Android checks images in under 3 seconds each.
