Script free with an account·render in about a minute·no watermark on any plan
AI Explainer Short Generator
One idea, explained in forty seconds, for somebody who is scrolling.
Start free — no credit card, and the script and the shot list cost no credits.
01Ask the question. One idea per video. The narrower the question, the better the explanation.
02Answer first, then why. The answer arrives by scene two; the rest of the video earns it one link at a time.
03Narrated and captioned. A deep documentary read with bold captions timed to the voice’s own word alignment.

What comes out
The settings this page ships with, and the shape they produce
Every example on this page is labelled with the exact configuration behind it, including the one that says it is a drawing.
Layout mock-up
Why aeroplane windows have a tiny hole in them
Style: Documentary
Voice: Adam
Captions: Bold

A mock-up of the frame and caption layout at this page’s settings — TikTok, Reels and Shorts, lo-fi music bed. It is a drawing, not a rendered video: we have no published render library to show you yet, and a stock clip dressed up as our output would be worth less than saying so.
Your input
“Why aeroplane windows have a tiny hole in them”
Plus this page’s brief, verbatim
Write this as a short-form explainer of exactly one idea. Line one is the question, phrased as a person would ask it. Line two gives the answer in plain words, before any mechanism. The middle scenes explain why that answer is true, one link in the chain per scene, using a concrete comparison rather than jargon. The last line is the consequence — what this means next time you see it.
That string is not marketing copy — it is the instruction the script writer is given before it reads a word of yours, and it is the only thing separating this page from the other forty-seven.
The shape that comes back
Scene 1 — the hook
One line that works with no context, because the viewer arrived mid-scroll.
Scenes 2–6 — the body
One idea each, one or two spoken sentences, each with its own image prompt and its own duration.
Final scene — the close
A line that lands the point rather than asking for a follow.
Per scene — the shot
The exact image prompt the model would receive, with this page’s style suffix already appended.
This is the structure, not a saved example. The box at the top of the page writes the real one — with your wording, in about ten seconds, free once you sign in.
5–8 scenes
each with its own line, its own frame and its own length
Under 60s
cut to the narration, not to a fixed per-scene timer
Word-timed
captions burned from the voice model’s own alignment

01
The answer goes at the front
Long-form explainers can tease. A vertical short cannot: the viewer arrived from a feed, they will give you three seconds, and a video that says “to understand this, we first need to talk about” has already lost them.
So this preset answers in scene two and spends the rest of the video making the answer make sense. Counter-intuitively that increases watch time rather than reducing it, because a person who has been given an answer they do not yet believe stays to find out why it is true.
02
One idea, and how to tell if you have picked one
The test is whether the question fits in a search box. “Why aeroplane windows have a tiny hole in them” does. “How aviation works” does not, and a forty-second video about it will be a list of assertions with nothing connecting them.
If your subject needs two videos, make two. This page writes a minute and the pipeline stops at three, and a short that tries to cover a syllabus ends up covering nothing — which is worse than a narrow video that somebody finishes.
03
How this differs from the explainer video preset
The explainer video generator is the general page: it takes a concept, a product or a process and produces the standard explainer shape. This one is tuned specifically for the short end of that — a single question, an answer inside the first ten seconds, and a close that pays out rather than summarising.
If you are not sure which you want, start on either. The voice, look, captions and length are dropdowns once you are in the app, and both pages hand the same script to the same pipeline.
Who this is for
Four people this was built for
Curiosity channels
The “why is it like that” genre, which is one of the largest on every vertical feed.
Teachers and communicators
One concept from the syllabus, explained in the length a teenager will actually watch.
Technical people explaining their field
You know the mechanism. The brief keeps you from starting three steps too far back.
Newsletter writers
The explainer paragraph you already wrote, in the format that travels further.
Compared
What this replaces
Six things somebody has to arrange to make one short, and who arranges them.
Input
The usual way: Research, script, motion-graphics brief, revisions, render.
With Veedio: The question. The answer-first structure comes with it.
Visuals
The usual way: Animated diagrams quoted per second, or stock that illustrates nothing.
With Veedio: A photoreal frame per beat, generated from that beat’s own line.
Voiceover
The usual way: Book a VO artist, or record yourself and cut the breaths out.
With Veedio: Five ElevenLabs voices, re-recorded free whenever the line changes.
Captions
The usual way: Auto-captions that drift, then an hour nudging keyframes.
With Veedio: Burned in from the voice model’s own word alignment, so they land on the syllable.
Turnaround
The usual way: A week, most of it waiting on an animator.
With Veedio: About a minute, and the script is free to read before you spend anything.
Changing it
The usual way: Re-record the line, re-cut the timeline, re-export, re-upload.
With Veedio: Edit the line and regenerate that one scene. Regenerating a scene is free.

Same engine, different preset
Twenty more pages over the same pipeline. Each one is a different brief, a different look and a different page — and each one prints its brief the way this one does.
How is this different from the explainer video generator?
This one is tuned for the short end: one question, the answer inside ten seconds, no summary at the end. The general explainer page handles concepts, products and processes at the standard length. Same pipeline, different brief.
Are the explanations correct?
They come from a language model’s general knowledge, which is good on settled science and unreliable on anything recent or contested. The script is free to read before you render — read it, and fix the line rather than the video.
Can it draw a diagram?
No. The image model produces photoreal or stylised frames, not labelled diagrams, and a generated “diagram” is usually confident nonsense with invented labels. The explanation lives in the narration and the captions.
How long will it be?
Five or six scenes, thirty-five to fifty seconds spoken. That is the band where a single-idea explainer holds all the way through.
Can I use a different voice?
Yes. Adam is the default because a documentary read suits an explanation, but all five voices are available on every generation and none of them are plan-gated.
Do I have to sign up to try it?
Yes, and it is free and needs no card. The script and the shot list cost no credits once you are signed in; the render is what spends the 60 free credits.
Do I have to sign up to try this?
Yes, a free one. Signup takes a moment and needs no card. Once you are signed in, the box at the top writes the script and the shot list for no credits — that is the part that decides whether the video is worth making — and rendering it into a file uses the 60 free credits the account starts with, about four videos.
What does it cost after the free credits?
Starter is $19 a month, Pro $49, Studio $149. A credit is a unit of pipeline cost rather than a video, so a five-scene short costs less than a nine-scene one, and you see the estimate before you spend anything.
Do I own the videos, and is there a watermark?
You own them, on every plan including the free credits, and there is no watermark on any plan, no resolution cap and no platform withheld. Four things do follow the plan, because they are what a video costs to make: AI motion and sound effects need Starter, a presenter avatar and the choice of video model need Pro, and a free account tops out at a minute where paid plans go to three. Everything else — every voice, every language, every caption style, every aspect ratio — is the same on all of them.
