The AI studio for serialised Shorts
You need to move fast, and you don't want six tabs, four models and a stitching job at the end — or a short that comes out nothing like the one in your head. Cast your characters once and they stay on-model across every episode. Approve each stage, see what it costs before you spend it, and leave with a finished 9:16 short.
Free to sign up, with 1,000 free credits — about five 30-second shorts at Standard.

Why it exists
Re-rolling a character who won't look the same twice. Paying for a render you could already tell was wrong. Rebuilding six scenes that were fine to fix the one that wasn't. Carrying files between four tools that have never heard of each other. Here's what we did about each one.
A character is cast once and saved to your library with a reference sheet — full body, close-up, three expressions. Every episode after that renders against the sheet, not against a lucky seed. Bring a character into a new video in one click and it arrives already on-model.
The cast sheet
Scene 1 · a kitchen
Scene 3 · school gates
The unit of work here is the scene, not the film. Re-roll a single frame or a single clip and spend credits on that one alone, leave the others exactly as they were, and stitch the result back together for free. Everywhere else, changing your mind about scene four means regenerating scenes one through seven and paying for all of them — which makes being fussy the expensive option, in a craft where being fussy is the entire job.
Every paid step shows you what it is about to send and what it is about to cost, then waits. Style probe first, full board second. A wrong look costs you a click, not a board of frames you have to throw away.
Script, cast, storyboard, voice, frames, film — all writing to one spec you can edit at any point and resume from. Captions burned per scene, clips cut to the voiceover's real word timing, exported 9:16. No hand-off folder.
The part nobody else gives you
The machine does the labour — research, drafts, renders, cuts. Every decision that ends up on screen is still a person's, and that person is you. You make each one before anything is paid for, not after.
A prompt box hands you what it guessed you meant. A crew hands you something to say no to, at every stage, before it costs anything. Which means your taste is what makes episode 30 better than episode 1 — and that compounds in a way a better model never will.
Under the hood
Each stage runs on whichever model is genuinely best at that one job, not on whichever one we started with — and they get swapped the moment something better ships. More are being added.
How it works
This is the actual pipeline, named honestly — the same six stages the app runs. Each one writes to a single spec you can edit, and each one stops for a yes.
Paste a rough idea or a script you've already written. It researches the story, offers three hooks built on genuinely different angles, and writes to the length you choose — ten seconds to two minutes — at a grade-7 reading level.
You approve the hook and the beats
Pulls out who is actually in the story and builds a reference sheet for each one. Anyone already in your library gets imported instead of rebuilt, so you pay for a character's look once, ever.
You approve the look, before it locks
Splits the narration into scenes of five to seven seconds, each with its own image prompt and on-screen caption. Rewrite a prompt, change a caption, delete a scene that isn't earning its seconds.
You approve every scene prompt
Audition voices on your real script, not a canned sample, then pick one. The voiceover comes back with word-level timestamps, so every scene knows exactly how many seconds it gets.
You approve the voice from a real take
One still per scene, generated against your locked character sheets. A single probe frame runs first so you can judge the style before the rest of the board renders, and any frame can be regenerated without disturbing the others.
You approve the style probe, then the board
Each still is animated, captions are burned onto their own scene, clips are fitted to the voiceover's real timing and mixed down with music to a finished vertical MP4. What it will cost, in credits, is on the button before anything renders.
You approve the price, in credits
The looks
The theme is set once, at the top, and every character sheet, frame and clip after it is rendered to match — including the way the medium moves when it animates. Clay steps. Anime holds, then snaps.
Each one is a genuine frame from a finished short, straight out of the pipeline. There's an eighth in the Studio: Real life — available light, real skin, no grade.

Questions
A studio that turns an idea into a finished vertical short in six steps: script, cast, storyboard, voice, pictures and film. It stops at each one for your approval, and you finish with an MP4 ready for YouTube Shorts, Reels or TikTok.
Yes. Every new account gets 1,000 credits, about five 30-second shorts at Standard quality (720p). No card, and nothing renews.
Every button that uses credits shows how many before you click. Writing the script, the cast list and the storyboard is free the first time; regenerating them, and every picture, voiceover and clip, uses credits. Redo one scene and you spend credits on that scene alone.
Paid plans aren't open yet. Email contact@shorts4u.ai and tell us what you're making.
That's what the cast is for. Each character gets a reference picture that every scene is drawn from, and you can save characters to your library and bring them into the next episode. Free accounts keep up to five characters and three locations.
You do, including for commercial use. Videos made on the free trial carry a small Shorts4U watermark, and we ask for a credit to Shorts4U in anything you post from the trial.
You can post them anywhere. If a video looks realistic, YouTube asks you to label it as altered or synthetic content when you upload. Whether a channel is monetised is YouTube's decision, made under its own policies on original content.
Yes. Download the finished video, or every scene as its own clip in one zip, ready to drop into your editor.
Not yet. Publishing straight to YouTube is coming. For now you download the video, and the Studio writes titles, a caption and hashtags to paste in.

I wanted to tell stories on a schedule, and every tool I tried made me pick between a look I couldn't hold from one episode to the next and a bill I couldn't predict. None of them let me be the director. They handed me whatever they guessed I meant, and charged me again when I disagreed.
So this is the thing I needed rather than a thing I thought would sell: every stage stops for me, the cast stays on-model across a series, and changing my mind about one scene doesn't cost me the six I was happy with.
I still use it every day, for my own channel.
