How to choose
- Your buyer needs to see the product: pick a tool that works from your real screens rather than generating lookalikes.
- Your buyer will trust a person on screen: pick a presenter-led tool.
- You're explaining a process with people in it: character animation suits it.
- You'll change copy or a price after launch: pick a tool whose output stays editable.
- You already have footage you want to keep: use a video editor.
Questions
- What kind of tool do I need for a SaaS explainer?
- It depends on what the video has to show. To show your real interface, you need a tool that works from your own screens rather than generating lookalikes. For a person on screen, a presenter tool. For a story with people in it, character animation.
- Does a SaaS explainer need an avatar or a presenter?
- No. Many SaaS explainers show only the product: your screens, the workflow and the result, with a voiceover. That's the kind Kario makes, with no avatar on screen.
- Can an AI explainer show my real product?
- Yes, if the tool rebuilds your screens. Kario takes screenshots or a screen recording of your app and rebuilds each screen as layers, matching its layout and copy.
- Can I edit the explainer after it's made?
- In Kario, yes: every word, number and screen is a layer you can change by hand or by asking in the chat, so a renamed feature doesn't mean a new video.
- Can I try Kario 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.
