Free YouTube AI Video Checker, No Signup
A "documentary" with a narrator who never takes a breath. A Short of a bear doing something no bear does. A news style upload about an event you cannot find anywhere else. YouTube has plenty of AI made video now, and not all of it is labeled. Get a copy of the video, drop it in below, and the checker reads the file in your browser for Content Credentials and AI labels, gives you a verdict, and shows you still frames to look at. The video is not uploaded. Free, no signup.
How to check a YouTube video
Find the moment that bugs you
Scrub to the part with the strange hand, the impossible shot or the face that looks waxy. That is the section to test.
Get the best file you can
If you made the video or the creator shared the original file, check that: it is the copy most likely to still carry Content Credentials or an AI label. If not, a short, steady screen recording of that section works for looking at frames. Play it at full quality and full screen first so you are not recording a blurry preview.
Expect no label on a recording
A screen recording is a new file, so the check finds no labels in it and says "No AI signs found". That tells you nothing about the original upload.
Look through the frames
Step through the still frames the checker shows you. If one lines up with the shot that made you suspicious, pause the video there and look closely.
YouTube videos are often long, and the copy you can get is rarely the creator's original file. So the trick is knowing what each copy can tell you.
Then compare what you found with YouTube's own label, if there is one.
YouTube's altered or synthetic content label
YouTube asks creators to say when their video contains realistic AI content. According to YouTube's help page on disclosing use of GenAI content, creators must disclose AI generated or altered content that seems realistic, including content that makes a real person appear to say or do something they did not do, alters footage of a real event or place, or generates a realistic scene that did not actually occur. Creators do this with an "AI use" setting in YouTube Studio when they upload.
Where the label shows up depends on the content. The same page says that for photorealistic AI content, a label may appear in the video player itself, while for content that is animated or not photorealistic the label may appear in the expanded description. YouTube's page on how this content was made disclosures describes a "How this content was made" section in the expanded description, and says the "Made with AI" disclosure can come from the creator, from YouTube's own AI tools, or from Content Credentials (C2PA) data showing the entire video was made with AI.
YouTube also says it may apply a label automatically for content made with its own AI tools, content that contains C2PA metadata, and content its internal systems detect as AI generated or altered.
So treat the label as one input. A "Made with AI" note plus a strong checker verdict is about as clear as it gets. No label plus a strong verdict is a reason to be careful with the claims in the video.
Common AI tells in long uploads and Shorts
Long uploads and Shorts go wrong in different ways, so it helps to know what to watch for in each.
In long uploads:
- Stock style B roll that does not match the script. The narrator talks about a specific street in a specific city; the footage shows a generic street with signs you cannot read.
- Recurring characters who drift. The "same" person looks slightly different from scene to scene: hairline, jaw, earrings, the pattern on a shirt.
- Perfectly even narration. No breaths, no stumbles, the same rhythm for twenty minutes. That points at the audio, not the picture, but it often travels with generated footage.
- Thumbnails and titles that promise footage the video never shows.
In Shorts:
- One impossible moment. Many AI Shorts are a single short scene built around something surprising. Pause at the peak of it and look at hands, paws and the ground.
- Loops that hide the seams. Watch where the clip restarts. Objects that jump or change between the last and first frame are worth a look.
- Captions doing the convincing. Big text telling you this "really happened" is not evidence of anything.

FAQ
Can I paste a YouTube link into the checker?
Drop in a clip file instead. The checker reads the file itself in your browser, so use your own copy of the video or a steady screen recording of the part you want to look at. A recording carries no labels, so it is mainly useful for its frames. It is free and needs no signup.
Does YouTube label AI generated videos?
YouTube requires creators to disclose realistic AI generated or altered content, and adds a label when they do. It says it may also label content automatically when it was made with YouTube's AI tools, carries C2PA metadata, or is detected by its systems. Labels can appear in the player or the expanded description.
If a YouTube video has no AI label, is it real?
Not necessarily. Creators do not have to disclose unrealistic content or minor edits, and some who should disclose will not. A missing label tells you little on its own. Check a clip of the suspicious part and look at where the video came from.
Why did the original file and my screen recording get different verdicts?
The original file may carry Content Credentials or an AI label, and a screen recording never does, because your phone made it as a new file. When the two disagree, trust what the original file says and look at where the video came from. The recording is still useful for its frames.
Can the checker tell which AI tool made a YouTube video?
No. It tells you whether the file says it was made with AI, not which model produced it. A label or description may name a tool, and YouTube shows an "Info from" attribution for some Content Credentials disclosures, but the checker itself does not name generators.
