AI Assistant

The OneCal AI Assistant is a chat built into OneCal. You can ask about your schedule in plain language, make changes to your calendar, manage your syncs and booking links, and get answers about how OneCal works.

To open it, click AI Assistant in the sidebar, or go directly to app.onecal.io/assistant.

The assistant is also available in the OneCal mobile apps for iOS and Android, with the exact same functionality.

What You Can Ask

The assistant works with all your connected calendars (Google, Outlook, and iCloud) and with everything you have set up in OneCal:

• Your schedule: Ask what is on your calendar, ask when you are free, or search for a specific event.
• Calendar changes: Create, edit, and delete events, or RSVP to meeting invitations.
• Calendar syncs: Check that your syncs are running, create new syncs, or pause, resume, re-run, and delete existing ones.
• Booking links and bookings: Create and update booking links, and confirm, decline, cancel, or reschedule bookings.
• Help and support: The assistant can search this documentation, so you can ask how a feature works or why something looks off. For example, "How does multi-way sync work?" or "Why do I see the same event twice?". If the assistant cannot solve it, you can always contact our support team.

If you are not sure where to start, pick one of the suggestions shown at the beginning of a new chat.

Nothing Changes Without Your Approval

The assistant never modifies your calendar, syncs, or booking links on its own. Whenever it is about to create, edit, or delete something, it first shows you a confirmation card with the exact details of the change. Click Confirm to apply the change, or Cancel to skip it.

Your Data and Privacy

The first time you open the assistant, OneCal explains exactly how your data is handled before you start. You see what is sent to the AI provider, who processes it and where, and that nothing sent is stored. You can review this and decide whether to continue.

Your data is never used to train AI models. This applies to OneCal, and it also applies to the AI provider that processes your messages.

Conversations stay on your device. OneCal does not store your chats on its servers, and chats do not sync between devices. Click New chat at the top of the page to start over at any time.

Usage Allowance

The assistant comes with a monthly usage allowance that depends on your plan. If you reach it, the assistant lets you know, and it becomes available again at the start of your next monthly period. Everything else in OneCal keeps working as usual in the meantime.
