Introducing Twelve Studio

TwelveAI ships a lot of product. Every launch needed a video, and every video needed someone to book a voiceover, cut a timeline, add captions and export three sizes. Most launches went out without one.

Twelve Studio is the tool we built to fix that for ourselves.

What it does

You bring what you already have: a brief, a script, your website, or a folder of screenshots. Twelve Studio turns it into a storyboard, voices every line, syncs captions to the spoken word, composes each scene and exports landscape, portrait and square MP4s from the same project.

What it is not

It is not a video generator. Nothing on screen is invented by a model. Scenes are composed from your words and your screenshots, so the result is predictable and on brand. A writing assistant helps with drafting and tightening the script, and that is all it does.

How it is built

• Voices run on open-source speech models on our own servers.
• Caption timing is measured from the generated audio, then snapped back to your exact words.
• Every frame is composed in code, so the same scene can be laid out correctly for any screen.

Try it

The free plan includes three 15-second videos a month on the full editor, with a small watermark. Dialogue scenes and longer videos start on Starter. Create your first video and tell us what you make.
