An AI explainer video generator that times the animation to your voiceover

Kario makes narrated, animated explainer videos from a brief. It drafts the script for you to approve, records the voiceover, and animates each scene to the narration, so a point appears on screen as it's said. You get an MP4, and an editable project behind it.

Every word on screen is a real text layer and every scene is a group of named layers with keyframes, so changing a line, a colour or a beat doesn't mean starting over.

Meta AI: Create from your world, made in Kario.

What you can change after it's built

  • Any text on screen: retype it in the editor.
  • Timing: hold a scene longer, move a keyframe, change an easing.
  • Look: colours, fonts and layout per layer or across the whole video.
  • Narration: rewrite a line and ask Kario to re-record and retime what follows.

Who it's for

  • Product and marketing teams explaining a product or a feature on a landing page or in onboarding.
  • Educators and trainers turning a lesson or a policy into a short video, in their audience's language.
  • Founders who need a how-it-works video for a sales deck or an investor update.

Questions

Does Kario write the script?
Yes. It drafts one from your brief, or works from yours. Ask to see the script before it records the voiceover.
Can Kario make explainers in other languages?
Yes. Set the language in the brief. Our step-by-step guide follows a French explainer from brief to export.
Is it a template tool?
No. Kario builds each scene for your script, and the result is a project you can edit layer by layer, not a template with slots.
How long can an explainer be?
Most are 30 to 90 seconds. The voiceover sets the length.
Is the voiceover included in the price?
Yes. A narrated explainer counts as one video, bought on its own or as part of a monthly plan. Re-recording the narration later uses revisions.
