Connect Kai to the AI app you use.
Ask in Claude, and it's done in your real calendar.
Watch me do it.
Ask about your week, move a meeting or book one. Kai checks both calendars, makes the change and tells you what it did.
Three meetings. Your 11:00 quarterly review clashes with the dentist on your personal calendar.
What to ask Claude or ChatGPT once your calendar is connected.
Copy one. I'm on it.
Book a meeting
You typeFind 45 minutes with Marco this week and add a Meet link.
Clear the afternoon
You typeSomething came up. Move what can move this afternoon to tomorrow, and show me first.
Spot double bookings
You typeWhat's on this week across all my calendars? Flag anything that clashes.
A real ChatGPT session: one message, two meetings moved.
Nothing cut.
ChatGPT on the web with Kai connected, unedited. One message clears the afternoon, and Kai moves the two flexible blocks to the next day.
Google Calendar MCP, answered
The fine print, short.
MCP is the standard that lets an AI app like Claude or ChatGPT use outside tools. A Google Calendar MCP lets it read your schedule and book, move or cancel events in your real calendar. Kai's does the same for Outlook calendars, on one connection.
Yes. Connect every Google and Outlook calendar you have to Kai, Google Workspace and Microsoft 365 included, and your AI app reads them together. Apple iCloud, CalDAV and Fastmail calendars don't reach the connector.
Yes, on any plan including the free one, once developer mode is on in Settings under Security and login. The recording on this page is a ChatGPT session.
No. Kai acts only when you ask, and cancelling a meeting waits for your explicit word. When it books or moves an event with other people on it, they get the invitation or the update, as they would from your calendar app. Ask to see the plan first and you get it before anything moves.
Most self-hosted servers need a Google Cloud project, OAuth credentials and a machine that stays on. Kai is one URL you paste into your AI app and approve once. Your email, meeting notes and tasks come on the same connection.
No. The Kai connector is free with your Kai account. Kai itself is a paid product after the trial.
Yes, at any time, from Kai. Access tokens are short lived, and the approval you gave can be pulled back in one click.
Connect Kai once, and your AI app reads every Google and Outlook calendar you have and books the meeting when you ask.
