How to Make an AI Explainer Video in 2026: Prompt, Script, Voice, Storyboard, and Final Video
A complete, practical workflow for creating an AI explainer video from a prompt, script, document, or recording. See three real Golpo examples, choose the right input path, plan the script and storyboard, direct the visuals, review the result, and publish it.
An explainer video is not simply text placed over stock footage. Its job is to move a specific audience from confusion to understanding through a connected sequence of narration and visuals. AI can remove much of the manual production work, but the result still depends on the audience, source, script, scene plan, and review process.

Short answer: define one audience and outcome, choose a prompt, script, document, or recording as the source, review the narration and scene sequence, choose the voice and visual treatment, generate the video, and run a factual and visual quality check before publishing.
Three ways to make an AI explainer video
These are real Golpo projects already documented in existing guides. The cards pair the source with the finished S3 MP4 so you can see how the input path changes the workflow.
One-sentence prompt → illustrated explainer
Why the Roman Empire fell
A short history brief becomes a paced, narrated explanation for a general YouTube audience.

What is a quantum computer?
A conversational script becomes an ordered visual explanation while the supplied wording remains the narration source.

Step 1: choose the right source for the job
| Starting point | Use it when | Best next guide |
|---|---|---|
| Prompt | You have an idea and want AI to draft the narration and visual sequence. | Text to Video in Minutes |
| Exact script | The wording is approved, regulated, branded, or performance-sensitive. | Script to Video in Minutes |
| Document | The video must stay grounded in a PDF, PowerPoint, Google Doc, report, SOP, or research paper. | PDF to AI Explainer Video |
| Your audio | You already recorded the approved performance or want to keep a real speaker's delivery. | Own Audio to Video |
| Speaking video | The presenter should remain visible beside or over the animation. | Picture in Picture |
The complete prompt-to-video workflow
1. Define one audience and one outcome
Write a one-line production brief: “After watching, [audience] should understand [idea] and be able to [action].” This keeps the script from becoming a general essay. A product evaluator, a new employee, a student, and a YouTube viewer need different context even when the topic is identical.
2. Gather the source and remove conflicts
Use the smallest approved source that contains the facts the video needs. Resolve contradictory dates, prices, names, and policies before generation. For factual topics, attaching a document is more defensible than asking a model to reconstruct the details from a vague prompt.
3. Build the narration around visual beats
A useful structure is: hook or question → context → mechanism or steps → concrete example → recap → one next action. Each beat should give the animation something meaningful to show: a process, contrast, sequence, diagram, example, or before-and-after state.
4. Decide who speaks
Use an AI voice for speed and repeatability, a saved voice clone for a reusable authorized narrator, Own Narration for the exact recording, or Picture in Picture when a real presenter should remain visible. These are different production choices, not interchangeable labels.
5. Choose the visual grammar
Golpo Sketch fits hand-drawn whiteboard explanations. Golpo Canvas supports richer illustrated scenes. Existing guides also show the available Sketch and Canvas styles, pen-in-hand animation, Custom Style, inserted images and video, and presenter layouts. Choose the simplest format that makes the idea easier to follow.
6. Put production direction in the right place
Keep spoken copy natural. Use Voice Instructions for delivery and pronunciation. Use Video Instructions for recurring layout, palette, typography, iconography, scene density, or on-screen script treatment. Use Custom Style when the full scene language should take inspiration from an image, video, or written style description.
7. Generate the first draft
Generation time varies with length, source material, selected options, and the active queue. Treat the output as a first production draft: watch it from beginning to end before editing individual details.
8. Repair the smallest unit
If one scene is wrong, correct that scene when frame editing is available rather than changing the entire brief. If the story itself is wrong, return to the script or source. If the delivery is wrong, fix the voice direction. Matching the fix to the layer avoids unnecessary rework.
AI explainer video quality checklist
- Accuracy: every name, number, claim, date, formula, and step matches the approved source.
- Story: the opening identifies the viewer's problem and the ending gives one clear next action.
- Narration: pronunciation, pacing, tone, pauses, and language fit the audience.
- Visuals: each scene supports the current narration instead of merely decorating it.
- Text: labels are readable, spelled correctly, and not overcrowded.
- Rights: you have permission to use the source, voice, images, footage, music, and brand assets.
- Format: orientation, duration, captions, thumbnail, and export match the destination.

Frequently asked questions
What is the easiest way to make an explainer video?
Start with one audience, one outcome, and one source. In Golpo, you can enter a prompt, paste an approved script, upload a document, or use your own recording; the platform creates narration and matching animated scenes.
Do I need to write the script first?
No. A prompt or document can be used to generate a script. Use Script Mode when every word is already approved or must remain controlled.
Can I use my own voice or webcam?
Yes. Own Narration can use uploaded or recorded audio. Picture in Picture keeps a webcam or speaking-video visual on screen; Audio in Video uses only the recording's audio.
Can I edit an AI explainer video after generation?
Editing depends on the plan. Current Golpo options include reviewing the script before generation and prompt-based frame editing on eligible plans. Check the live pricing page for current plan details.
What should I review before publishing?
Check factual accuracy, names and numbers, narration, on-screen text, scene-to-script alignment, source rights, branding, captions, orientation, and the final call to action.
