How Vizzy uses your Google Calendar

Vizzy reads your calendar, finds windows that fit a request, and books with the right details. No grid scrolling.

1.

Connect your Google Calendar to Vizzy

From Sintra, open Vizzy and choose the Google Calendar integration. Sign in with the Google account that holds the calendar you live in.

2.

Tell her what you want booked

Type the request the way you would tell a person. 'Find 45 minutes with Sarah next Tuesday afternoon.' 'Block 9 to 11 every weekday for deep work.' Vizzy comes back with options that already match your availability.

3.

Confirm and move on

Pick the slot. Vizzy creates the event, adds the title, and sends invites if you asked her to. The event lands on your Google Calendar with the link, location, or video room set.

Frequenly asked questions

What can a Google Calendar AI assistant do?

It reads your calendar, finds slots that match your preferences, books meetings, sends invites, and blocks focus time. In Sintra, Vizzy is the helper for calendar work. She talks to you in chat and writes to Google Calendar through the integration.

Will Vizzy book without my approval?

By default she shows you the slots and waits for confirmation. If you set up a Recurring Scheduled Task, like a weekly Friday review, she creates the events on the cadence you defined without asking each time.

What Google permissions does Vizzy need for Calendar?

Vizzy needs Google Calendar read and write access on the account you sign in with. Approve the scopes on the Google sign-in screen. For Google Workspace accounts, your admin may need to allow the Sintra app.

Does she protect my focus time?

She does if you tell her your focus hours. Add them to Brain AI as a recurring rule. When meeting requests come in inside those windows, Vizzy offers alternatives instead of booking over them.

What if Vizzy books a meeting at the wrong time?

Ask Vizzy to reschedule the event in chat. The change pushes to Google Calendar and invitees get the new time. Set your default time zone in your Sintra account to prevent repeat zone misreads.
