What the AI actually does
"AI video generator" covers very different products. Some generate realistic footage; some put an avatar in front of slides. Sketchvo does something narrower and, for explaining things, more useful:
- Plans the explanation. It decides what the viewer needs to hear first, second and last.
- Writes the narration. Short spoken sentences, one idea each, at roughly 150 words per minute.
- Illustrates every sentence. A picture is generated for what that line is about.
- Animates the drawing. Each picture is traced by an on-screen hand, then revealed.
- Narrates it. A natural voice in one of 15 languages, in sync with the drawings.
Prompts that produce good videos
The AI can't read your mind, but it doesn't need much. Give it four things:
| Part | Example |
|---|---|
| Topic | How the heart pumps blood |
| Audience | for nursing students in their first week |
| Goal | so they can name the four chambers in order |
| Length & tone | 2 minutes, calm and clear |
When a generator beats doing it yourself
- You need many videos, often — a course, a channel, a training library.
- The content already exists in a document or web page.
- You need the same video in several languages.
- Speed matters more than custom art direction.
When it doesn't: if every frame must match a brand illustration guide, a designer with manual tools will get closer.
Other ways to start
Prompts are one option. You can also turn a PDF into a video, paste your own script, or drop in a link to an article.
Free to try
You can start free: every account gets one AI-made video, plus five free Studio videos every day where you write the scenes and choose the pictures (720p, small watermark, kept for seven days). Paid plans start at $19.99 a month, and one credit makes one minute of finished video.
Five prompts that produce good videos
| Use | Prompt |
|---|---|
| Lesson | Explain photosynthesis to 11-year-olds so they can say what a plant needs and makes. 90 seconds, friendly. |
| Product | Explain how our invoicing app saves freelancers time chasing payments. 60 seconds, confident, end with 'try it free'. |
| Training | Walk new cashiers through processing a refund in four steps. 2 minutes, calm and clear. |
| YouTube | Tell the story of how the printing press changed Europe, with a hook in the first line. 6 minutes. |
| Social | Three surprising facts about octopuses, 30 seconds, vertical, playful. |
How to improve a generated video
The first draft is a starting point. The fastest improvements come from the script, not the pictures:
- Sharpen the hook. Replace a generic first line with a question or a number.
- Cut the weakest scene. Most drafts are better ten seconds shorter.
- Make one sentence more concrete where a picture looks vague.
- Add your own example — a real customer, a local place, a class in-joke.
AI whiteboard video vs. other AI video tools
| Tool type | Output | Best for |
|---|---|---|
| AI whiteboard generator (Sketchvo) | Hand-sketched scenes with narration | Explaining, teaching, training |
| AI avatar tools | A digital presenter talking to camera | Talking-head updates, announcements |
| AI footage generators | Short realistic or cinematic clips | Visual moods, b-roll, ads |
| Slide-to-video tools | Slides with voiceover | Converting presentations as-is |
If your goal is that someone understands something by the end, the whiteboard approach usually wins: the drawing paces the information instead of decorating it.
Is AI-generated content any good?
It's as good as the brief and the review. Treat the AI as a fast first-draft writer and illustrator: you bring the purpose and the judgement, it brings speed. Check facts, cut fluff, and make sure the video says what you would say.
Frequently asked questions
What is an AI whiteboard video generator?
A tool that creates a whole whiteboard video — script, illustrations, drawing animation and voiceover — from a short text prompt.
How long does generation take?
Usually a few minutes after you confirm the script, depending on length.
Can I change the script the AI writes?
Yes, every scene can be edited before the video is generated.
Which languages are supported?
Narration is available in 15 languages.
Does it make realistic video or avatars?
No. Sketchvo makes hand-sketched whiteboard and doodle videos, not live-action footage or avatars.
Can the AI research a topic for me?
It structures and explains topics well, but you should check facts and figures — especially for specialised or recent subjects.
Can I regenerate if I don't like the result?
Yes. Edit the script or the request and generate again.
