Google Calendar in Claude and ChatGPT

In short

The Fezola Google Calendar connector lets Claude and ChatGPT read events across all your calendars and Google accounts, find a slot that is free everywhere, and create, change or delete events. Guests are only notified when the assistant is told to.

Connect Google Calendar

Updated on November 14, 2026

What your assistant can do

What your assistant can do
Action	Read or write	Detail
List and search events	Read	Across every calendar of every connected Google account, each event showing its account and calendar.
Find free time	Read	Computed across all connected accounts at once.
Create an event	Write	Needs write access, granted when you connect.
Move or edit an event	Write	Guests receive nothing unless the assistant is told to notify them.
Delete an event	Write	The event goes to the calendar's trash and can be restored for 30 days.

You can connect read-only: writing then fails with a clear message.

When to choose Fezola

Several Google accounts: one assistant sees personal and work calendars together, and free time is found across them.
Calendar next to mail: the same connector holds your mailboxes, so "find the invitation and check my availability" works in one conversation.
The same connection in Claude and ChatGPT: one URL serves both. ChatGPT custom connectors are available on Business, Enterprise and Edu plans.
One calendar, one assistant: an assistant's own Google Calendar connector can be enough, if it fits your plan. Check your assistant's documentation for the current steps.
A shared Memory: your preferences, such as "no meetings before 10", follow you across assistants.

Several accounts

Events from every connected Google account come back together, each showing its account and calendar. Example: "What do I have tomorrow across my personal and work calendars?"

Questions to ask (example prompts)

“What do I have tomorrow across my personal and work calendars?”
“Find 45 minutes this week that is free on all my calendars.”
“Move my 3 pm call with Martin to Thursday morning, without notifying anyone yet.”
“Create a one-hour block named Review on Friday at 10 in my work calendar.”
“List my meetings with an external guest this week.”

A typical use

Someone has a personal and a work Google account. They ask: "Find 45 minutes this week that is free on both calendars and block it as Review." The assistant computes free time across the accounts, proposes a slot, and creates the event in the calendar you name, without emailing any guest unless told to. Example scenario, not a customer story.

Safety

Writing needs write access. By default guests are added without any email: invitations, change notices and cancellations go out only when the assistant is told to notify guests. Deleted events can be restored for 30 days. Event text is treated as data, never as instructions. Keep your assistant's approval prompts on, and remove any account in Fezola at any time.
