AI Biology Video Generator
Name a living thing, an organ or a process inside one, and get a narrated biology video that zooms from the whole organism to the part doing the work, one illustrated and captioned scene at a time.
01Name the structure or process. An organ, a cell, a life cycle or a process, at the level you want. Paste your exam board’s wording if it must be kept.
02Check the biology. The explanation comes back as a script before anything renders. Correct a term, cut a claim or reorder a stage.
03Zoomed in, scene by scene. Each level or stage gets its own illustrated scene — organism, organ, cell — a narrated line and captions on every word.

Your input
“How the heart pumps blood around the body”
Plus this page’s brief, verbatim
Write this as a short biology video that explains one structure or one process in a living thing. Open on the whole organism or an everyday moment where the biology is at work, then zoom in step by step — organism, organ, tissue, cell, as far as the topic needs — one scene per step, saying what each part does and why its shape suits the job. For a process or a life cycle, go through the stages in order, one per scene. Name each biological term the first time it is used and say what it means. Where biologists are still unsure, say so plainly. Explain the biology only: give no medical advice, no diagnosis and no treatment, and keep anatomy textbook-clean with no injury or gore. Use only well-established biology; if the user gives their own facts or their exam board’s wording, keep them exactly. Never invent a statistic, a measurement, a study, a quote or a source; leave a number out rather than guess it, and put no real person on screen. Describe every scene through something an illustration can show — the creature, a cutaway, a close-up — without labels or written text.
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.
5–8 scenes
each with its own line, its own frame and its own length

01
From the whole organism down to the part doing the work
Biology is easiest to follow when you know where you are. The brief starts on something whole and familiar — a runner breathing hard, a leaf in the sun, a caterpillar on a stem — and zooms in one level per scene, organism to organ to tissue to cell, only as far as the topic needs, saying at each step what the part does and why its shape suits that job.
For a process or a life cycle the brief goes through the stages in order, one per scene, so the video ends where the cycle starts again. Each biological term is named the first time it appears and explained in the same line, which lets a younger viewer keep up and gives an older one the vocabulary an exam will ask for.
02
Textbook biology, in your exam board’s words
The script comes from a language model’s general knowledge: dependable for settled, textbook material and not to be trusted on anything recent or contested. You read every line before a frame is drawn, and you can correct or replace any of it at no cost. The brief keeps to well-established biology, says plainly where biologists are still unsure, and leaves a number out rather than guess it.
If your specification uses particular wording — the stages of mitosis, the parts of a flower, the route blood takes through the heart — paste it and say to keep your facts: the script uses it exactly as typed. It explains biology and gives no medical advice, diagnosis or treatment, keeps anatomy textbook-clean, and puts no real person on screen.
03
Cutaways of cells and organs, drawn without labels
Each scene is one illustration drawn from its own line — a picture of the idea, not a labelled diagram, a chart or a worked equation; the words on screen are the captions. On a paid plan each frame is set in motion by default (68 credits for a five-scene video), or choose Stills in the composer and the same video is 13 credits. A cutaway of a heart, a cell with its parts in one consistent look, or a caterpillar becoming a chrysalis works well; a labelled cell diagram for a test, a Punnett square or a graph of results does not.
Pick landscape in the composer for a classroom screen or a YouTube video, or keep vertical for Shorts and TikTok. There are 5 voices, all recorded in American English. There is no British, Irish or Australian voice and no voice cloning. The narration and captions can be in any of 29 languages — French, German, Spanish, Italian, Dutch and Polish among them — chosen in the composer; the voices read them, but a native listener may hear the American accent, so listen to the first one before you post a series.

Visuals
The usual way: License microscope footage or commission medical animation.
With Veedio: An illustration drawn from each step’s own line, in one consistent look.
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.

The script comes from a language model’s general knowledge: dependable for settled, textbook material and not to be trusted on anything recent or contested. You read every line before a frame is drawn, and you can correct or replace any of it at no cost. The brief leaves out a number rather than guess it; paste your own figures or your textbook’s wording to include them exactly.
Can it explain a health condition or give medical advice?
It explains how the body works, not what to do about it: the brief gives no medical advice, diagnosis or treatment. A video for patients should be written and checked by a clinician, and pasted in as your own facts.
Will it draw a labelled diagram of a cell?
No. Each scene is one illustration drawn from its own line — a picture of the idea, not a labelled diagram, a chart or a worked equation; the words on screen are the captions. On a paid plan each frame is set in motion by default (68 credits for a five-scene video), or choose Stills in the composer and the same video is 13 credits.
Can it match my level or exam board?
Yes — say it in the box: primary, Year 9, GCSE, A level, AP Biology, or “for a general audience”. It does not read a specification, so paste the points and terms the video must use and say to keep your facts.
Are there British voices?
There are 5 voices, all recorded in American English. There is no British, Irish or Australian voice and no voice cloning. The narration and captions can be in any of 29 languages — French, German, Spanish, Italian, Dutch and Polish among them — chosen in the composer; the voices read them, but a native listener may hear the American accent, so listen to the first one before you post a series.
What does it cost?
Plans are monthly: Mini $7 (200 credits), Starter $19 (600 credits), Pro $49 (2,000 credits), Studio $149 (7,500 credits). A five-scene short in pictures costs 13 credits; with AI motion in every scene it costs 68. You see the price before you generate, and the first payment on any plan has a 7-day money-back guarantee. Mini ($7 a month, 200 credits) covers about 15 five-scene shorts in pictures, or about 2 with AI motion in every scene.
Can I post it straight to TikTok, Reels and Shorts?
Connect TikTok, Instagram and YouTube once and publish to TikTok, Reels and Shorts from the app, on every plan. Mini connects 1 account, Starter 3, Pro 6 and Studio 25. Or download the video and use it anywhere.
Do I own the video?
You own the videos on every plan and can use them commercially, paid ads included. There is no watermark on any plan, the export is 1080p, and the music beds are licensed for commercial use with no attribution. Every video is made on a plan: Mini is $7 a month, and the first payment on any plan has a 7-day money-back guarantee.
Do I have to sign up to try this?
Yes, and pick a plan: Mini is $7 a month, and the first payment has a 7-day money-back guarantee. On a plan, 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.
What does it cost?
Mini is $7 a month for 200 credits, Starter $19 for 600, 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, 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, and a presenter avatar and the choice of video model need Pro. Everything else — every voice, every language, every caption style, every aspect ratio — is the same on all of them.
