Do I need to download the video first?

No. For public posts the link is enough. For private ones, save the video and upload the file.

Why did my link fail?

Usually because the post is private, needs a login, or was deleted. Some sites also block automated downloads now and then; trying again a minute later, or uploading the file, solves most cases.

AI video checker by link: paste a link, get an answer

No need to download anything. Copy the post's link in the app, paste it here, and we fetch the video, check it, and read the post's caption and tags for AI labels, all in about a minute.

Reddit, Vimeo and 1,000+ more sites

When a link won't open

Private accounts, Stories and posts behind a login can't be fetched: save or screen-record the video and upload the file.
Deleted posts take their video with them: upload a copy you saved instead.
Videos over 10 minutes are too long: trim the part you want checked and upload it.

What a link tells us that a file can't

The post itself: its caption and hashtags (like #sora or #aiart), the platform's own AI label where there is one, and the claim it makes, which we look up in published fact-checks.
