FAQ
Before you buy.
What happens after the trial?
Settings, Recents and demo mode keep working, and nothing is deleted. Sending a message needs a license.
How many Macs can I use?
3 per license. Deactivate a Mac in Settings, License, to move its seat.
Do updates cost extra?
No. Every 1.x update is included. The app confirms its license with Polar about once a day and keeps sending for 44 days without a successful check. The terms have the details.
Is there a student discount?
Yes, 30% off. Email me from your school address and I'll send a code.
Can I get a refund?
Yes, within 30 days, no questions. See the refund policy.
What leaves my Mac?
Your messages go to Anthropic when you send them. The signed app also checks its license with Polar and looks for updates on this site. The privacy policy lists every detail.
Can I build it for free instead?
Yes. The source is MIT licensed and builds with Xcode in three steps: install XcodeGen, clone the repository and run scripts/run.sh.
If you build it yourself and want to support the work, you can sponsor Otto on GitHub.
