About Void Calendar

Void Calendar is an AI calendar and time-boxing app for Mac. Tell AI what you need to do, and it places the work into time that is actually free, next to your existing events. Tasks, notes, and focus records live in the same place.

Your events, tasks, notes, and AI conversations stay in a database on your Mac. AI scheduling uses your own model endpoint and API key, so requests go from your Mac straight to the provider you chose.

The current release is the public beta 0.1.0-beta.7, published October 26, 2026. It runs on Apple Silicon Macs with macOS 13 or later and Intel Macs with macOS 13.4 or later, reads Apple Calendar, syncs selected Reminders lists, and connects Google Calendar and iCloud Calendar.

Planned next: apps for iPhone and Android, Windows and Linux builds, and connections to Todoist, Microsoft To Do, Google Tasks, and Outlook Calendar. These are not available yet, and the changelog only lists what has shipped.

Void Calendar is made by Void Vision Pty Ltd, an AI product company based in Sydney, Australia. We build tools that help people get real work done with AI.
