Features

Tuned for the first three seconds

Shorts live or die on the opening. Clips are trimmed to start on the line that earns attention rather than the setup leading to it.

Length that fits the moment

Clips end where the thought closes instead of at a fixed timer. You can set a target length if you want them uniform, but nothing gets cut off mid-sentence to hit a number.

Auto-post to YouTube Shorts

Connect your channel and Shorts publish from AutoClip, spaced across the day. The same clips can go to 12 other destinations without re-rendering.

Captions burned in by default

Word-synced captions on every Short, in karaoke, pop, or bounce styles, with your brand kit fonts and colors applied automatically.

How It Works

1

Paste a long-form video URL

Podcasts, streams, lectures, interviews — any public YouTube, Twitch, or Kick source.

2

Shorts-shaped moments get pulled

Segments with a strong open and a quick payoff rank highest, then get reframed to 9:16 and captioned.

3

Publish to your channel

Post directly, or schedule across the week so the channel looks consistently active instead of spiky.

Frequently Asked Questions

What makes a good YouTube Short?

A first line that creates a question, a payoff that arrives before attention runs out, and no dead air at the front. Length matters less than pacing — a 45-second Short that keeps moving finishes better than a 20-second one that meanders. Clips are selected against roughly those criteria, and you can see the score breakdown for each.

Can I generate Shorts from someone else's YouTube channel?

Yes, any public video works, and plenty of clippers build audiences this way. Whether you should is a separate question: check the source creator's stated policy, and know that some channels actively encourage clipping while others do not.

How is this different from making Shorts by hand?

By hand, one Short means watching the source, choosing the moment, cropping to vertical, timing captions, exporting, and uploading — call it 20–30 minutes if nothing goes wrong. Here, a typical video produces around nine clips in about 10–15 minutes total, and your work is choosing among them. You give up frame-level control, which is a real tradeoff if the edit itself is your craft.

Does it generate multiple Shorts from one video?

Yes — around nine from a typical video, all in the same pass. Per-video caps are 6 on Starter, 12 on Pro, 15 on Scale.

How long can a YouTube Short be?

YouTube now counts uploads up to 3 minutes as Shorts, though shorter still tends to complete better. Clips default to the 30–60 second range and you can raise or lower the target.

Is there a free AI Shorts generator?

The free tier gives watermarked trial clips and 2 connected accounts. Starter at $19.99/mo includes 200 credits (one per minute of source), 10 videos, watermark-free export, channel monitoring, and auto-posting to YouTube Shorts.
