Reddit AI checker

Is this Reddit video real or AI?

Paste the link to a public video on Reddit and check it. We fetch the video and let two AI models look at the picture, since Reddit re-encodes uploads.

What a Reddit link can tell us

Reddit re-encodes video when it hosts it, so a signed record from the tool that made the clip is usually gone. For most Reddit videos the picture does the work, and we say so rather than pretend the metadata is there.

Reddit is where a suspicious clip often gets posted with a question mark in the title. If the post links to the original source, or another post has the original file, checking that gets a stronger signal.

What the picture shows

Two open-source models share the work: cakelens follows how the video moves from frame to frame, and Community Forensics reads single frames for the traces generators leave. We calibrate the combined score on our own set of real and AI clips, with cut-offs set so real phone footage rarely comes back as AI.

The timeline under the verdict marks the moments that look most generated. Where the evidence is mixed, the verdict says Inconclusive rather than picking a side.

Where it struggles

A clip that has been downloaded and re-uploaded loses detail with each step, which weakens the signal. Screen recordings, small or very dark videos, and heavy compression do the same, and the newest video models are the hardest to catch.

A low score means no sign of AI turned up, not that nothing was changed. Look at the rest of the thread too: what happened, and whether anyone has the original footage.

FAQ

Questions, answered honestly.

Do I need a Reddit account?

No. Paste the link to a public video on reddit.com or redd.it and we fetch it, check it, then delete our copy. A video that only loads on the page has to be downloaded and uploaded as a file instead.

Which Reddit links work?

Links to public videos hosted on Reddit. If the post embeds a video from another site, paste that site's link instead.

How accurate is it?

Our test results page lists every generator we test and how often real videos come back as AI. A re-encoded Reddit clip is not one of those clean files, so weigh the verdict with the rest of the evidence. See the test results
