YouTube's new AI turns long videos into up to 12 captioned Shorts

The platform's new tool handles the most tedious part of Shorts creation — finding the moments, reframing them vertical, and adding captions.

You just uploaded a 30-minute podcast episode, and now you know the real work begins — finding the quotable moments, clipping each one, reframing it for a phone screen, and adding captions so people actually watch with the sound off. That's the part most creators quietly skip. YouTube says its new AI Shorts tool handles almost all of it.

What the tool actually does

According to YouTube's announcement, the workflow has two parts. First, you (or the AI) find the moments in your long video worth clipping — the bits that stand alone as watchable Shorts. Then the AI turns those moments into vertical clips with captions already burned in, all in one batch.

The result is up to 12 finished Shorts from a single long video. Each one is in vertical format (the tall shape that fills a phone screen) and already has captions added (the text that pops up on screen so people can follow along with the sound off). You don't have to re-edit or re-export anything before posting.

Why this matters for creators

Shorts are the format YouTube leans on hardest for new-viewer discovery. Most creators find that posting them regularly is part of how a channel grows — but it's also the most tedious part of the workflow, since each Short has to be clipped, reframed, and captioned by hand. Third-party clipping tools have built whole businesses around this single pain point.

YouTube's new tool is the platform's answer to that friction. Instead of treating Shorts as a separate job, it tries to make them a byproduct of the work you're already doing. Upload one video, get up to 12 clips back.

What's still unclear

YouTube's announcement describes what the tool does, but leaves a few practical questions unanswered. Worth knowing before you go looking for it:

The post doesn't specify which YouTube surface hosts the feature — the YouTube Studio desktop dashboard, the mobile app, or both.
It's not clear whether the AI picks the moments automatically, asks you to mark them first, or does some mix of the two.
There's no word yet on which accounts have access — all creators, or just YouTube Partner Program members — or whether it's a paid add-on.
The "up to 12" cap suggests the AI decides how many clips make sense for the source video. A 5-minute vlog might produce fewer than a 90-minute interview.

If you want to find it, check your YouTube Studio dashboard or the help center for the latest rollout details in your region.

What this means for you

If you make videos as a hobby: this could turn a single long recording session into two weeks of Shorts content with almost no extra editing. Think of a long family vacation video — the AI might pull out the funniest moments, the scenic shots, the memorable quotes.
If you create content for a small business or as a creator: you already know that posting Shorts consistently is how new people find your channel. This is the closest thing yet to letting the platform do the clipping for you, which is exactly the part most creators want to skip.
If you're just curious: this is part of YouTube's bigger push to keep creators inside its ecosystem rather than using third-party clipping tools. The fewer places you have to upload, the more YouTube controls the experience.
If you already use Shorts: this won't replace a thoughtful editor who picks moments with intent — but it will compress the time between "uploaded" and "posted" from hours to minutes, which is the part most creators would happily give up.

Wrap-up

YouTube's new AI Shorts tool won't replace the creative judgment of a real editor, but it does compress the most annoying part of the workflow — finding, clipping, reframing, and captioning — into something close to automatic. If you publish long videos and have been putting off the Shorts side of things, this might be the nudge that makes it worth doing. Check your YouTube Studio dashboard in the coming weeks to see whether the feature has rolled out to your account.
