It started at a crossroads.
In Japanese, 岐路 (きろ, kiro) means a fork in the road or a crossroads. It can also describe a turning point, a moment when you have to choose which path to take.
I started Kirocast because I felt I was at that crossroads. For me, nothing is more valuable than building my own company, listening to the people using my product, facing rejection, and growing after every conversation.
Kirocast is my everyday companion. It helps me work with agents, debug, share ideas, and automate videos. I’m building the tool I want by my side, and I hope you’ll enjoy working with it too.
If something feels off, please send me a message and I’ll do my best to help!
A few things
to know.
Everything else you might be wondering before your first recording.
Can I try Kirocast for free?
Yes. Download Kirocast and use every feature for free - recording, auto-zoom, privacy masks, backgrounds, the editor. Export is the one thing a license unlocks, so you can see exactly what you would be paying for before you pay.
What makes a recording useful to an AI agent?
Kirocast prepares the recording alongside your transcript and annotation information. Paste the handoff into an agent that can read the exported files on your Mac, so it can inspect what happened and understand what you said.
Can I make regular product demos too?
Yes. Record your screen, edit the timeline, adjust zooms and backgrounds, add captions, and export a finished video with a license. The agent workflow is one way to use Kirocast.
Is this a subscription?
No. Personal is a one-time payment with no automatic renewal. You get the Kirocast license, including all updates.
Can I transfer my license?
No. Kirocast licenses are personal and cannot be shared, resold, or transferred to another person or company.
Are my recordings processed in the cloud?
No. Recording, editing, transcription, and export run on your Mac. You decide when and where to share the exported files.
What if it isn’t for me?
The Personal license has a 14-day money-back guarantee.Read the refund policy.
Which version of macOS do I need?
Kirocast requires macOS 15 Sequoia or later. Download the app and try the workflow on your Mac before buying a license.
