How do you record a product demo on a Mac?

Kirocast records your Mac screen and turns the capture into a polished product demo: automatic zoom follows the action, smart annotations call out what matters, and cursor movement is smoothed. It is the same app indie developers use during the build to hand a recording to a coding agent, so the demo comes out of a recorder you already have open. Personal is a one-time $39 launch purchase, normally $49. Kirocast runs on macOS 15 or later.

What a raw capture costs you

  • A raw screen capture makes a good product look mediocre. Viewers cannot tell where to look, and the details that actually sell are illegibly small.
  • The fix is worse than the problem: keyframing every zoom and callout by hand in a video editor, or re-recording until one take is clean. Either way a 60-second demo eats an afternoon.
  • The demo is due the week you are least able to give it an afternoon - launch week, when the product is finally ready and everything else is on fire.

What Kirocast does about it

Automatic zoom on the action

The frame moves to where the work happens: clicks, typing, UI changes. Viewers always see the detail that matters, and the framing is generated from the recording itself.

Smart annotations

Loop your cursor around something while you record and Kirocast spots the gesture and draws the callout in post. Your hand does the pointing; Kirocast does the drawing.

Record, polish, export

Capture a take, refine it after the fact, and export demo-ready video for a landing page, App Store page, or launch post. Minutes, not an afternoon.

The recorder you already had open

Kirocast spends the build handing bug recordings to your coding agent. When it is time to ship, use the same app and familiar shortcuts to capture polished product demos. One purchase covers both jobs.

Common questions

How long should a product demo video be?
For a landing page, 30–90 seconds. Lead with the outcome in the first five seconds, show the two or three moments that differentiate the product, and end on the result. Attention drops fast after the first minute.
What makes a demo look professional?
Emphasis and motion: the frame zooms to the action, the cursor moves smoothly, and callouts guide the eye. Resolution matters less than never making the viewer hunt for where to look.
Can I use Kirocast for both launch demos and my AI agent?
Yes. They are separate captures for separate jobs. Use Talk mode to record a bug for your AI agent: hold two keys, talk, then let go. When it is time to ship, record a clean product demo and export it with automatic zoom, smart annotations and smoothed cursor motion.
