An explainer video sells the idea: why your product exists and why it matters. A product demo proves it: how the product actually works. If people don't yet understand what you do, start with an explainer. If they understand it but want to see it working before they buy, start with a demo.
What an explainer video does
An explainer is for people who have just met your product. It answers three questions in 60 to 90 seconds: what problem do you solve, what changes with your product, and why should I care. It shows the product, but only the moments that make the idea click.
It usually lives on your homepage, in pitch decks, and at the top of sales emails. Our Kairos brand film is a good example: it opens on a problem every auto garage knows, and the product only appears once the viewer already wants it.
What a product demo does
A demo is for people who already get the idea and now want proof. It walks through one real workflow, start to finish, so the viewer can picture using it. The best demos rebuild the interface for motion, so every click is easy to follow and there's no dead time.
It usually lives on feature pages, in sales follow-ups and in onboarding. The Kairos booking demo shows a whole booking flow in 32 seconds: book, confirm, sync.

Which one should you make first?
- Visitors leave your homepage confused: make an explainer. A demo won't help people who don't know why they'd want it.
- Prospects ask for a demo call before buying: make a demo. It answers the question before the call, and sometimes replaces it.
- You're launching: make both. The explainer brings people in and the demo converts them. Our Growth package ($5,900) is built for exactly this.
- Your product changes often: a demo with a rebuilt interface ages better than a screen recording, because small design changes don't date it.
Can one video do both?
Yes, when the product is easy to grasp and you have one main audience. A hybrid opens like an explainer, then spends its second half inside the product. Our Rayhane launch video does this for an e-learning platform: the story of the platform first, then the app, its features and its teachers.
A hybrid needs a bit more length, usually 80 to 90 seconds. If your product needs more than one workflow to make sense, two short videos will work better than one long one.
Mistakes to avoid
- Putting a feature tour on the homepage, where visitors still need the "why".
- Using a raw screen recording as a demo: loading screens, typos and a wandering cursor lose people.
- Trying to show every feature. One workflow, done well, beats ten done quickly.
- Skipping the next step. Both videos should end on one clear action.
