SaaS explainer videos, built from your real product

Kario is an AI tool that makes animated explainer videos for SaaS and B2B software. Give it your website, plus screenshots or a screen recording of your app, and it writes the script, records the voiceover, rebuilds your screens as layers and animates each one to the narration.

The interface on screen is yours, not a generated lookalike, so a buyer sees the product they'll actually use. And because every word is a real text layer, a renamed feature or a new price is an edit, not a new video.

What a short SaaS explainer covers

  • The problem, in your buyer's words. Kario starts from your site's own copy.
  • One workflow on your real screens: the click, the typing, the result landing.
  • The outcome, with a number you can stand behind.
  • One next step on the end card.

What to give Kario

  • Your website URL, for copy, colours and type.
  • Screenshots or a screen recording of your app. Kario can't sign in, so anything behind a login has to come from you.
  • Who buys it, and the one thing they should remember.
  • The length: 45 to 90 seconds for a landing page, around 20 for a feature post.
  • A voice: American or British, male or female, a native Spanish, French, German or Portuguese voice, or your own recording.

After it's built

  • Retype any text on screen in the editor, or ask for the change in the chat.
  • Rewrite a line of the script and ask Kario to re-record and retime what follows.
  • Ask for other shapes: 16:9, 9:16, 1:1 and 4:5 sit as boards in one project.
  • Add languages: each can be its own board, sharing the layout, brand and assets.

Questions

What should a SaaS explainer video include?
The problem in your buyer's words, one workflow on your real screens, the outcome with a number you can stand behind, and one next step on the end card.
Can Kario show my actual app?
Yes. Upload screenshots or a screen recording and Kario rebuilds each screen as layers, so a buyer sees the product they'll actually use. Kario can't sign in, so anything behind a login has to come from you.
Does Kario write the script and record the voiceover?
Yes. It writes the script from your site's copy and your brief, and records it in American or British English, male or female, or native Spanish, French, German and Brazilian Portuguese voices; other languages are read by the same voices. Or use your own script and recording.
How long should a SaaS explainer be?
45 to 90 seconds for a landing page or a sales email, and around 20 for a feature post. About 140 words of narration runs a minute.
Can I update it when the product changes?
Yes. Every word is a text layer and every screen is rebuilt as layers, so a renamed feature or a new price is an edit. Rewrite a line of the script and Kario re-records it and retimes what follows.
Can I see the explainer's plan before I pay?
Yes. Sign up and describe the video, and Kario plans it as a storyboard, shot by shot, for free. Changing it is free too: reply in the chat with what to change. You pay only when you want Kario to build it, and your first purchase is covered: if the video isn't what you asked for, Kario fixes it, and if it still isn't, you get your money back.
