An explainer video maker for showing how software works
The fastest way to explain software is to show it. Skrimo records your screen and voice, then automatically zooms in on what you click so viewers can follow along, and exports a polished video. No animation skills or editing required.
Skrimo is a free mac screen recorder that records internal audio, your microphone and webcam, then adds automatic zoom and a polished frame.
Screen-recorded explainers vs animated explainers
Animated explainer tools are great for abstract ideas. For software (an app, a website, a workflow), a screen-recorded explainer is faster to make, always accurate, and easy to update when your product changes. If you need to teach a task step by step, a tutorial is the better format; for your homepage and launches, make a short product demo.
Make an explainer video in minutes
- Write three to five points you want to explain.
- Open Skrimo, turn on your microphone (and webcam if you want a face on screen).
- Record yourself walking through each point in the app.
- Skrimo adds zooms where you clicked; trim the start and cut any mistakes.
- Pick a background and export for your website, YouTube or social.
Why auto-zoom matters for explainers
On a full-screen recording, buttons and text are tiny, especially on a phone. Skrimo zooms toward the area you’re working in, so viewers see exactly what you’re explaining without you editing a single keyframe.
What makes a good software explainer
- One idea per video. If you need “and”, make two videos.
- Show the result first, then how to get there.
- Talk to one person, in plain words, like you would on a call.
- Keep it to 60–120 seconds for websites and social; longer only for deep dives.
- Make sure small text is readable on a phone. That’s what auto-zoom is for.
A simple script template
- Outcome: “In one minute you’ll see how to …”
- Context: the problem in one or two sentences.
- Walkthrough: the three key moments in the product.
- Recap and next step: what to try, and where.
Recording settings that help
- Record a single window so notifications and other apps stay out of the shot.
- Use 16:9 for websites and YouTube, 1:1 or 9:16 for social feeds.
- Turn on the webcam bubble for a personal touch, especially for sales and onboarding.
- Export MP4 at 1080p for the web or 4K for YouTube; use a GIF for short loops in docs.
