Make Explainer Videos with AI
Start with what you already have: a PDF, a slide deck or a page of notes. VibeKnow writes the narration, designs every scene and adds voiceover and music, so you get an explainer without storyboarding, recording or editing.
Add one line about who's watching and how long it should be. The explanation follows it.

Explainers made with VibeKnow
Three clips, each with its own way of showing the idea.
Sketched: how to take on a task
A pen draws each point on a white page. Step one is “Ask three questions first”: who it's for, when it's due and what's done. Step two is “Repeat the task back”.
Animated diagrams: why plane windows are rounded
Force lines bunch up at a sharp window corner and flow smoothly around a rounded one, with a gauge for the stress at the corner.
Illustrated: what a landlord can deduct
A bear walks through what can come out of a rental deposit, such as a hole in the wall or unpaid rent, and what counts as normal wear and tear.
How to make an explainer video with AI
- 01
Bring your material
Upload a PDF, Word file, PowerPoint deck, TXT or Markdown file, up to 50 MB. Notes and outlines work as well as finished documents.
- 02
Set it up for your audience
Add a line about the audience, length or focus. Then pick a video type, landscape or vertical, a narration voice and music.
- 03
Review, edit and export
VibeKnow writes a scene-by-scene script, designs the visuals and records the narration. Change what you want, then export an MP4.
Four ways to show your idea
Pick a video type on the next screen. The same material can be explained in any of them.
HTML Video
Images and graphics are laid out on a canvas and turned into an editable video, in landscape or portrait.
Image Video
The AI draws the visuals for every page, then adds voiceover and transitions.
Slide Video
Your content becomes a slide-by-slide explainer. Edit the text, images and narration on any slide.
Hand-drawn
Pictures are turned into line art and drawn on screen stroke by stroke.
The hard parts of an explainer, handled
A storyline to follow
Your material is shaped into a scene-by-scene outline, so the explanation builds one idea at a time.
Narration written to be heard
The text is condensed into a spoken script that sounds like someone explaining it, not someone reading it aloud.
Visuals that carry the idea
Numbers become charts, processes become step-by-step animations and comparisons become side-by-side layouts.
Voiceover and music included
Choose a narration voice and music before you generate. No microphone, no recording session.
Made for the people watching
One line about the audience changes the result: an overview for managers or a walkthrough for new hires.
Yours to change and reuse
Edit the result before you export. Besides the MP4, you can download the script, voiceover and captions.
What people explain with it
Employee training and onboarding

Product walkthroughs

Three ways to make an explainer video
Each one fits a different job. Here is where the work goes.
| Film or screen-record it | Hire an animation studio | VibeKnow | |
|---|---|---|---|
| Starting point | A script and a camera or screen recorder | A creative brief | The document you already have |
| Who does the work | You write, record and edit | Writers, designers and animators | AI writes, designs and narrates; you review |
| Making changes | Re-record or re-edit | Another revision round with the studio | Edit the result and export again |
| Best for | Face-to-camera content and live demos | Flagship brand films | Regular explainers, training and lessons |
