AI Storyboard Generator: from script to scenes, with timing

Paste a script and it gets split into scenes exactly as written. Describe an idea and the narration gets written too. Every scene shows the visual, the one line of on-screen text, the spoken words, the motion, and how many seconds it takes.

Your scenes land here.

Each scene shows what is on screen, the one line of text the viewer reads, the spoken narration, and how it moves. Then copy it, download it, or build the video from it.

An AI storyboard generator turns a script or an idea into the scene-by-scene plan a video is built from. Instead of sketches, this one gives you what a motion designer actually needs: the composition of each frame in words, the single line of text a viewer reads on screen, the narration spoken over it, a note on how the scene moves, and a time estimate, all laid out on a timeline. It works on a vertical 9:16 canvas for TikTok, Reels, and Shorts, or a widescreen 16:9 canvas for YouTube and websites. When you paste a finished script, the wording is preserved and only split at natural beats; when you give it an idea, it writes the narration with a hook in scene one. The storyboard copies as Markdown, downloads as a file, and builds as an animated video in one click.

Everything you need

Built for creators who want fast, high-quality results.

Five things per scene

What is on screen, the on-screen text, the exact narration, the motion, and the seconds. Enough to brief a designer or build it yourself.

Script in, scenes out

Paste a finished script and it is split into scenes as written, never rewritten or shortened. Or give it an idea and get the narration too.

Two canvases

Vertical 9:16 storyboards compose tall with one focal object and room for captions. Widescreen 16:9 storyboards use side-by-side layouts and left-to-right flows.

Timeline view

Every scene's share of the runtime on one bar, so you can see where the video drags or rushes before anything is built.

Streams as it thinks

Scene cards fill in one by one as the plan is written. No spinner for thirty seconds; the first scene is readable in a few.

From storyboard to video

One click carries the narration into the Motion Graphics studio, where each scene gets designed, animated, voiced, and captioned.

How it works

Four steps. Under a minute.

1

Paste a script or describe the video

A finished script keeps its words. A one-line idea gets narration written for it. Up to 3,000 characters.

2

Pick the canvas and scene count

Vertical for Shorts, Reels, and TikTok; widescreen for YouTube. Let it choose the number of scenes or fix it at 4, 6, 8, or 10.

3

Watch the scenes arrive

Each card shows the frame, the on-screen text, the narration, and the motion note, with a running total on the timeline.

4

Copy, download, or build it

Copy the storyboard as Markdown, download it as a file, or send the narration into the studio and generate the video.

Perfect for

Explainer and educational videos

Plan how a concept unfolds frame by frame: the mental model, the naive version, the problem, the fix. See the visuals before you animate anything.

Product launches and ads

Storyboard the pain, the turn, the product in use, and the proof in as many scenes as the ad has seconds.

Training and onboarding

One step per scene with the on-screen label a learner needs to read, so the video can be reviewed by the team before it is produced.

Client pitches and briefs

Agencies hand clients a numbered scene list with timing instead of a wall of text. Download it as Markdown and drop it in the deck.

YouTube and faceless channels

Break a long script into visual beats so every section has something on screen, not just a voice over a static image.

Motion designers and editors

A shot list with composition, text, and motion notes per scene, ready to build in any tool or to generate here.

Frequently asked questions

Is the AI storyboard generator free?

Yes. You can storyboard here without an account. There is a fair-use limit of a few storyboards every ten minutes per visitor. A free Brainrot Shorts account lets you build the video from the storyboard, with free credits to start.

Does it draw the storyboard frames?

It describes each frame precisely in words and shows the on-screen text as it would appear, on a 9:16 or 16:9 frame. That is what a designer or an animator needs; when you build the video in the studio, every frame is designed and animated for real.

Can I storyboard an existing script?

Yes. Paste the script and it is split into scenes at natural beats. The wording is kept as the narration and nothing is skipped or shortened.

How many scenes does a short video need?

Most 60 to 90 second explainers land at 5 to 8 scenes, roughly one idea every 8 to 12 seconds. Leave the scene count on Auto to let the material decide, or fix it when a brief calls for a specific number.

What is the difference between a storyboard and a shot list?

A shot list is the camera plan for a live shoot. A storyboard is the visual plan for each scene, which is what an animated or motion graphics video is built from. This tool produces the storyboard, with the narration and timing attached.

Which canvas should I pick?

Vertical 9:16 for TikTok, Instagram Reels, and YouTube Shorts. Widescreen 16:9 for a YouTube video, a website hero, a course, or a presentation.

How do I turn the storyboard into a video?

Click 'Turn this into a video'. The narration is carried into the Motion Graphics studio as the script, and the studio designs and animates a frame for every line, adds an AI voice or your recording, word-timed captions, and a licensed music bed.
