How to make YouTube Shorts with AI
- 01
Write your idea
One sentence is enough. You can also paste a full script or a TikTok link to adapt. Pick a style, a tone, a length and a voice language.
- 02
Shape the story
Rewatch drafts the plot, the dialogue and the list of shots, and designs the characters. Rework the opening, rename someone, cut a scene: it is all editable.
- 03
Check the first scene
A single scene is rendered so you can judge the look and the voices. Correct it with a sentence, then generate the remaining shots.
- 04
Upload to YouTube
Download a captioned 9:16 MP4 and upload it as a Short. The same file works on TikTok, Reels, Facebook and Snapchat.
Why story channels pick this AI YouTube Shorts generator
An opening that earns the swipe
The script is written so the first line raises a question the rest of the Short answers. You can rewrite it before anything is rendered.
Full arcs, not fragments
Each Short has a setup, a turn and a payoff. Viewers get an ending, which makes the video feel complete in under a minute.
Recurring characters for your channel
Series mode keeps the cast, voices and universe locked, so every new Short continues the same world and returning viewers recognize it.
Animated from start to finish
No static slideshow. Every shot gets a slow, motivated camera move and the framing follows whoever is talking.
Readable captions
Captions are added to every video automatically, so your Short makes sense on mute in the Shorts feed.
Cheap previews with Images only
Generate the whole story as still images first, check it, and animate later. The price of each step is shown before it runs.

What is an AI YouTube Shorts generator?
An AI YouTube Shorts generator produces vertical videos for the Shorts feed from a text prompt. It handles the parts that usually take hours: writing a script that hooks in the first seconds, creating visuals, recording a voice over, editing and adding captions. You get a 9:16 file ready to upload.
Rewatch is built for narrative Shorts. Rather than stitching stock clips together, it writes an original story, designs characters that stay identical across shots and episodes, voices each one and animates every shot. Two checkpoints keep you in charge: you approve the story and cast, then the first scene, before the rest is produced.
