How to tell if a YouTube video or Short is AI
Where YouTube shows its AI disclosure, what the channel's history tells you, the habits of AI Shorts and narrated videos, and how to scan a YouTube link.

To tell if a YouTube video or Short is AI, look first for YouTube's own AI disclosure near the player or in the description, then check the channel's history, then scan the link. YouTube asks creators to disclose realistic AI content, but not all do, so the channel and the scan usually settle it.
YouTube is different from Instagram or WhatsApp in one useful way: almost everything has a channel behind it with a public history. Use that.
1. Find YouTube's AI disclosure
Since 2024, YouTube has required creators to disclose when a video contains realistic content that was altered or made with AI, such as a person saying something they never said or an event that never happened. Creators tick a box when they upload.
Where the disclosure shows has changed over time, so look in a few places. At the time of writing, YouTube says:
- For photorealistic AI content, the label appears just below the player on regular videos, and as an overlay on the video itself in Shorts.
- For animated, unrealistic or lightly altered content, the note sits in the expanded description, in a section called "How this content was made".
The wording may vary, for example "Altered or synthetic content" or "Made with AI". YouTube also says it may add the label itself when its systems detect significant AI content the creator didn't disclose, when the video was made with YouTube's own AI tools, or when the file carries Content Credentials saying it was made with AI.
As with every platform, a missing label proves nothing. It depends on honest creators and on systems that miss things.
2. Look for the opposite label too
YouTube also has a "Captured with a camera" note, shown in the same "How this content was made" section when the video was recorded on a device that adds Content Credentials and wasn't edited in ways that break them. It's still rare, because few cameras and phones support it. If you see it, that's a meaningful sign the footage came from a real camera. If you don't, it means nothing either way. Our explainer on Content Credentials covers how these markers work.
3. Read the channel, not just the video
Tap the channel name and look around. Opening the channel's description usually shows when it joined.
- Age and rhythm. A channel a few weeks old with hundreds of Shorts, uploaded several times a day, is a common sign of a content farm.
- A face or a voice that never varies. Real presenters have bad hair days, different rooms and different moods. AI presenters can look and sound identical in every upload, or subtly different in ways a real person wouldn't be.
- Sudden topic switches. A channel that posted gaming videos last year and now posts "shocking footage" of disasters may have changed hands or changed tactics.
- Unrelated "events". Dozens of unbelievable moments from different countries, all with the same look, the same music and the same narration voice.
4. Know the habits of AI Shorts
Shorts suit AI tools. Generated clips are usually short, and a Short can be stitched from several of them.
- Loops hide endings. A clip that loops neatly avoids showing what happens next, which is where cause and effect would be tested.
- Several short shots, no continuous take. Look for whether any single shot lasts longer than a few seconds.
- Narration over everything. A synthetic voice reading a dramatic script over clips you can't verify is a format worth recognising. If the voice is the claim, check it with an AI voice detector.
YouTube has also built AI video generation into its own Shorts tools, using Google's Veo models. Google says videos made that way carry an invisible SynthID watermark and a label. Clips made with Veo outside YouTube and uploaded afterwards are a different matter: they may carry no visible label at all. Our Veo detection page explains what still gives Veo away.
Here's a result from our test set: a frame from a clip of a surfer riding a wave, made with Runway Gen-3. Action clips like this can end up in "best moments" compilations next to real footage. Our video model scored it 99% AI.

5. Long videos: "documentaries" and news-style channels
Some long videos follow a pattern of their own: an authoritative narration, a mix of stock footage, a few real news clips and AI-generated scenes for the parts nobody filmed. Ask:
- Does the description list sources you can check?
- Are the dramatic scenes, such as a "secret meeting" or a "never-seen-before" disaster, the ones with no named source?
- Does the narrator ever appear, or only a voice?
6. Scan the link
Tap Share, then Copy link, and paste it into our YouTube video checker. A Quick Scan is free to try, needs no sign-up and answers in under a minute for most videos. For links, it also reads the title, description and tags, and looks for published fact-checks.
A few things to know:
- Private, members-only and age-restricted videos need a login, so a checker may not be able to fetch them. If you can watch it, screen-record the part that matters and upload the file.
- Long videos: checks work on videos up to 10 minutes. For anything longer, record the part you care about and upload that.
- Shorts compilations: if only one clip in the Short matters, a Deep Scan checks every second of picture and the whole soundtrack, so a single AI shot among real ones is less likely to slip through.

Quick answers
Does YouTube label all AI videos?
No. It labels videos creators disclose, videos made with its own AI tools, videos with AI Content Credentials, and some that its systems detect. Plenty of AI videos carry no label.
Where is the AI label on a Short?
At the time of writing, YouTube says photorealistic AI content gets a label overlaid on the Short itself, with other disclosures in the expanded description. Interfaces change, so check both.
Can I check a YouTube video for free?
Yes. Paste the link on the home page for a free Quick Scan, no sign-up needed.
