Make YouTube Shorts from a few lines of script
A Short lives or dies in its first line. Write that line, add two or three more, and our AI makes the vertical video around it.
For Shorts, paste a short script, pick vertical 9:16 and a fast voice, and our AI makes a 1080×1920 video with a new picture every sentence and word-timed captions. Most fact Shorts in the gallery are 13 to 17 seconds long and were made from three or four sentences.
The example, and the script it came from
- Vertical 9:16
- 17 s
- Voice: Will
- Captions: karaoke
This is the whole script that went in. Everything else (the narration, the pictures, the graphics and the captions) our AI made from it.
On Venus, a day is longer than a year. Venus takes 243 Earth days to spin once, but only 225 days to circle the Sun. And it spins backwards. So on Venus, the Sun rises in the west.
The example: a day on Venus
This Short is 17 seconds, narrated by Will with karaoke captions. Its whole script is three short paragraphs: "On Venus, a day is longer than a year. Venus takes 243 Earth days to spin once, but only 225 days to circle the Sun. And it spins backwards. So on Venus, the Sun rises in the west."
The first sentence is the hook, the numbers are the proof, and the last line is the twist that gets the replay.
A Short in four beats

Settings that suit Shorts
- Vertical 9:16, exported at 1080×1920: the size YouTube recommends for Shorts
- A voice at 1.1x to 1.25x: Shorts reward pace
- Pop or karaoke captions, large, kept clear of the bottom where YouTube puts its buttons
- Under 3 minutes, which is YouTube's limit for Shorts uploaded since October 2024 (most good ones are far shorter)
Make the series, not one video
Shorts channels post often. Keep one look and one voice, paste the next fact, and each Short comes out matching the last. The scripts stay in your list of videos, so a weak one can be retyped and rendered again.
For Shorts cut from your own footage instead of a script, open the video in the editor and ask the chat to cut the pauses, caption it and set the hook.
Long video in, Short out
Made a landscape video already? Ask the chat for a 9:16 copy and our AI makes a vertical version with the captions and graphics moved into the vertical frame, ready to trim down to its best minute.
- Made a vertical 1080×1920 copy
- Cut it to 0:31-0:47
- Moved the captions into the vertical safe area
Questions
