Example scripts the generator writes
Two real-shape samples, structured the way the generator returns them — a hook, then one visual and one narration line per scene.
How Volcanoes Work
2 min · 6 scenes · ~344 wordsTopic: How volcanoes work
Hook: The ground beneath your feet holds a heat engine powerful enough to split continents — and occasionally rewrite the map.
- 1Scene 1
Draw: A cross-section of Earth: thin crust, flowing mantle, hot core.
Earth isn't solid all the way down. Beneath the thin crust we live on sits a mantle of slow-flowing rock, heated from below by the planet's core.
- 2Scene 2
Draw: Glowing arrows rising from deep in the mantle toward the surface.
That heat drives convection — hot rock rises, cools, and sinks again in a slow rolling current that drags the crust above it.
- 3Scene 3
Draw: Two tectonic plates pulling apart; magma rising through the gap.
Where plates pull apart, pressure drops and the rock partly melts into magma. Lighter than the rock around it, the magma rises.
- 4Scene 4
Draw: A magma chamber swelling under the surface, bulging the ground.
Much of it pools in a chamber a few kilometers down, slowly filling and pressurizing like a shaken soda bottle.
- 5Scene 5
Draw: Magma bursting through the vent; an ash cloud rising.
When the pressure exceeds the strength of the rock above, the magma breaks through. Gases trapped in it expand violently — and the volcano erupts.
- 6Scene 6
Draw: Cooling lava solidifying into new crust; a calm summit returns.
The lava cools into new rock, adding to the crust. It's destruction and creation in the same breath — Earth recycling itself, one eruption at a time.
Compound Interest, Explained
1 min · 5 scenes · ~172 wordsTopic: The basics of compound interest
Hook: The most powerful force in finance isn't a stock tip — it's just math, given time.
- 1Scene 1
Draw: A single coin dropped into a jar labeled 'savings'.
Compound interest means earning interest on your interest. Start with $100 earning 5% a year and you've got $105 after year one.
- 2Scene 2
Draw: The $105 grows; a small slice labeled 'interest on interest' appears.
In year two you earn 5% on $105 — not on the original $100. That extra few cents is interest on your interest, compounding.
- 3Scene 3
Draw: A line curving upward, getting steeper each year.
Repeat that for decades and the curve bends upward. The gains from earlier years keep earning their own gains, snowballing.
- 4Scene 4
Draw: Two side-by-side bars: 'starts at 25' far taller than 'starts at 35'.
Time matters more than amount. Someone who saves a little starting at 25 can end up ahead of someone who saves more, starting at 35.
- 5Scene 5
Draw: A snowball rolling downhill, growing larger.
So the trick isn't timing the market — it's starting early and letting the math do the heavy lifting for you.

How to write a video script
The same six steps the generator follows — useful whether you use the tool or write by hand.
Start with one clear idea
Before you write a word, name the single thing the viewer should understand by the end. If you can't say it in one sentence, the script will wander. Everything else — the hook, the scenes, the visual cues — exists to deliver that one idea.
Open with a hook in the first 5 seconds
Most viewers decide whether to keep watching before the first scene ends. Lead with a question, a surprising fact, or a promise of what they'll learn — not an introduction of yourself or your brand. The hook lives in scene 1.
Put one concept in each scene
A whiteboard scene is a single beat: one idea, one drawing. If a scene needs two drawings to make sense, split it. The generator sizes scene count to your target length (5 scenes for 1 min, up to 15 for 5 min) so there's room to slow down rather than cram.
Write to a real narration pace
A natural voiceover runs about 172 words per minute. That's roughly 30 words per scene for a 1-minute, 5-scene script. Writing to that pace keeps the script from running long — the generator sizes every script to it automatically, but it's the rule to follow if you edit by hand.
Pair each scene with a visual cue
For every scene, note what should be drawn. A good cue is one short phrase — "a cross-section of Earth" or "two side-by-side bars" — not a paragraph. The drawing should show what the narration says, not decorate around it.
End with a concise recap
The final scene restates the core idea in one or two sentences and, if it fits, points the viewer to a next step. A clean recap is what makes an explainer feel finished instead of just stopping.
Prefer to skip the blank page? The generator above applies all six steps for you — then turn the script into a finished whiteboard video on Ankon AI, or browse the guides and how-tos for more on writing and producing explainer videos.
Video length, word count, and cost
How the generator sizes a script. Word counts use a real narration pace of ~172 words per minute; scene counts and credits match what a finished Ankon AI render would use.
| Length | Narration words | Scenes | Credits to render | Best for |
|---|---|---|---|---|
| 1 min | ~172 | 5 | 2 | A single concept or a social Short |
| 2 min | ~344 | 6 | 2 | One concept with a short setup |
| 3 min | ~516 | 9 | 3 | A 'how it works' explainer with sub-ideas |
| 5 min | ~860 | 15 | 5 | A deeper tutorial or step-by-step walkthrough |
Credits follow Ankon AI's standard rate — 1 credit per minute of finished video, with a 2-credit minimum. Generating the script itself is always free.
Frequently asked
Is this AI video script generator really free?+
Yes, it's completely free and no account is required. Sign up only when you want to turn a script into a finished, narrated, captioned video.
How does the AI script writer work?+
Enter a topic and pick a target length (1, 2, 3, or 5 minutes). The generator writes a hook, splits the narration into the right number of scenes for the chosen length, and suggests a whiteboard visual for each scene. It sizes the word count to real narration pace (~172 words per minute) so the script lands close to your target runtime.
Can I turn the script into a real video?+
Yes — that's the point. The 'Generate this video with Ankon AI' button opens the video builder with your topic prefilled. Ankon AI renders your script as a narrated, captioned whiteboard explainer with AI-drawn scenes, a real voice, and publish-ready metadata. New accounts get 2 free credits (no card required).
How long should my explainer video be?+
1–2 minutes is ideal for a single concept or a social Short. 3–5 minutes suits a 'how it works' explainer with a few sub-ideas. The generator tells you the scene count and credit cost for each length up front.
Who owns the scripts I generate?+
You do. The scripts are plain text you can copy and use anywhere — in your own videos, presentations, courses, or content. The generated script itself is not stored on our servers. To monitor abuse of this free tool, we log the topic you submit plus usage metadata (length, language, scene count, status, and the model used) against a hashed IP — never the script body, and never your raw IP address. Admins can review this log; it is not shared with anyone else.
What languages does the script generator support?+
You can generate narration in 12 languages including English, Spanish, French, German, Italian, Portuguese, Hindi, Japanese, Chinese, Korean, Arabic, and Dutch — matching the languages Ankon AI can narrate and caption.
