Before you install.
Operating system
macOS 14 Sonoma or later
Jikoku is a native Mac application and uses recent Apple frameworks.
Processor
Apple Silicon required
The current local language model runs on Apple chips.
Memory
8 GB target, more gives headroom
Local models are queued to avoid running speech and language processing together.
Local models
About 8.4 GB, downloaded in the beta
In the Public Beta the speech and language models are optional downloads you start yourself in Settings.
Beta download
About 13 MB, models excluded
The beta disk image carries the application only. Reserve room for the models if you decide to install them.
System access
Calendar, Reminders, Contacts, Microphone
macOS asks for each protected permission when the related function needs it.
About Gatekeeper and distribution
The beta is signed without Apple notarization, so macOS blocks the first launch. Open it through System Settings, Privacy & Security, Open Anyway. Never bypass a warning for a package that did not come from an official Jikoku channel.
The beta is free and has no expiry. Pricing, trials, App Store purchase and restore-purchase controls are intentionally absent until those flows exist. Read the privacy architecture before leaving your email.
