the process

how it works

  1. 1. Bring the video file

    Download your own video from YouTube Studio or use the original recording, then upload the file here. Pasting a YouTube link is not the path right now — YouTube audiovisual import is disabled while prior written Google approval is pending.

  2. 2. Moments come back with reasons

    Speech is transcribed with timing and the whole recording is analyzed — the intro hook, the payoff, the aside that landed. Every suggested clip carries a plain-language reason you can read before downloading.

  3. 3. Review and re-post

    Clips download as vertical 9:16 MP4s with captions burned in — upload them in YouTube Studio like any Short. Signed-in creators can also upload reviewed clips directly; Direct YouTube upload is available to signed-in creators; Public or Unlisted visibility stays gated until Google restores this app's YouTube API upload-audit status.

built for your own catalog

This page is for re-cutting videos you have the rights to — your channel's downloads, your raw recordings. Long-form uploads already proved the material works; Shorts are the second distribution pass, not a re-shoot.

what stays in your control

Every clip waits for your review: play it, read the reason, keep it or skip it. Nothing posts itself, and nothing leaves the job page until you download or upload it.

answers

FAQ

Straight answers on formats, limits, and what happens to your video. More detail lives in help.

Does it upload the Shorts for me?

For signed-in creators, yes — after review, connect YouTube in Settings and upload. Direct YouTube upload is available to signed-in creators; Public or Unlisted visibility stays gated until Google restores this app's YouTube API upload-audit status. Anyone can download the MP4s and post manually in YouTube Studio.

Do I need to own the video?

Process files you have the right to process — typically your own downloads and recordings. That keeps the re-use rights question settled before the first clip exists.

Is it free?

Yes: 4 hours of source video a week, no card required — enough for a typical long-form upload. Guests share a lighter weekly job cap per network; free exports carry a watermark and paid plans remove it.

What do the Shorts look like?

Vertical 9:16 MP4s with captions burned in, ready for YouTube Studio. Each one arrives with a title and the plain-language reason it was picked.
