AI Motion Graphics Generator — Your Script, Animated
Write a script or upload your narration, and the AI designs and animates the whole video — titles, numbers, and diagrams that move with every word you say. Captions land word by word, sound effects hit on cue, and the finished MP4 comes out ready for Reels, TikTok, and YouTube Shorts. No After Effects, no templates, no timeline.
Up to 3 minutes of narration per video · AI voices or your own recording · vertical 9:16 or widescreen 16:9
Why the same picture ends up two very different sizes. Generated from a script — nothing was animated by hand.

API rate limiting
What stops one user from hammering an API.
An entire 108K-follower account runs on this generator
@rick.theengineer posts animated tech explainers — how caching works, what a rate limiter does, why PNG beats JPEG — and every video on the feed is made with this tool. The account’s bio says it outright: “videos made with brainrotshorts.com”. Its biggest reels have passed half a million views, carried by exactly what you saw above: one idea per frame, cut to the words being spoken.

From script to finished motion graphics in three steps
You bring the words. The generator does the storyboarding, the design, the animation, the captions, and the sound — the parts that normally take a motion designer hours per minute of video.
Pick who's talking, then write the script — or upload your voice
One narrator, or two characters talking it through. Type what the video should say and pick a voice to read it, let the AI write it from a topic, or upload a recording of yourself. Up to 3 minutes either way. You hear every voice before anything is animated, so nothing is a surprise.
Pick a style — or have one designed for your video
Choose a design style from the library, or let the AI invent one for your exact content: it asks a few quick questions about audience and mood, then designs the look fresh while your video builds — you see it take shape in the progress panel.
Generate, then download
The AI storyboards your narration, designs every frame, times the captions to each word, mixes in music and sound effects, and renders the video. You watch each stage as it happens, then download an MP4 — vertical 9:16 or widescreen 16:9 — ready to post.
A typical video is ready in about 20 minutes — the AI designs every frame from scratch for your narration, and you can leave the tab while it works.
Everything a motion designer would add — added for you
Captions timed to every word
Word-by-word captions are burned into the video, styled to match the design — the reason these videos hold attention with the sound off. Turn them off for training videos where the words on screen are the point.
Numbers and diagrams that land
Say a stat and it becomes the frame: huge type, counters that count, meters that fill. Describe a flow or an architecture and the AI draws it step by step as you talk through it.
Two people talking
Turn any topic into a conversation: pick two characters, write or paste their lines, hear every one in its own voice, then generate — each speaker animated as they talk, reacting to the other.
Sound design included
A licensed music bed sits under your narration and sound effects hit on the cuts — mixed so your voice always wins.
A presenter, if you want one
Pick a character — or upload your own image — and it becomes an animated presenter that walks through the video with your narration. Or stay fully faceless.
Built for where you post
Vertical 9:16 for Reels, TikTok, and YouTube Shorts, or widescreen 16:9 for YouTube — with every element kept inside each platform's safe zones, so nothing hides behind the UI.
Motion graphics used to mean software or invoices
After Effects & motion designers
Beautiful, but hours per minute
- Steep skill curve — keyframes, easing, expressions
- A one-minute video is a day of work, or a $300+ invoice
- Total creative control for the people who have the craft
Template editors
Fast, but it's someone else's video
- Your content squeezed into a layout made for other content
- Captions, timing, and music are still on you
- Fine when a generic title card is all you need
This generator
Designed from your words
- Every frame designed for your narration — nothing pre-made
- Captions, music, and sound effects timed and mixed for you
- Script in, finished MP4 out — about 20 minutes
Starting from a document instead of a script? The AI Explainer Video Generator turns a PDF, slide deck, or notes into a narrated video. This page — the motion graphics generator — is for when you already know what you want to say and want it animated word for word.

AI motion graphics generator questions, answered
An AI motion graphics generator turns spoken words into an animated video without any manual animation work. You give it a script or a voice recording, and it storyboards the content, designs every frame, animates titles, numbers, and diagrams, times captions to each word, and mixes in music and sound effects. The result is the kind of video a motion designer would normally build by hand in After Effects — produced from your narration in about twenty minutes.
Your next video is a script away
Write it or record it — the AI designs, animates, captions, and mixes the rest. The first draft of your animated explainer can be rendering twenty minutes from now.
