Claude + Google Calendar: Connect It and Book Events
Yes. Add the Carly connector to Claude, connect Google Calendar, and Claude can book, move and cancel meetings, then set up triggers right from the chat: when this happens on your calendar, do that. “When a meeting with a new client gets booked, send me a prep brief the night before.” You type it once in Claude. Carly runs it every time, whether Claude is open or not.
Where Claude and Google Calendar fall short today
Claude’s own Google Calendar connector can read and manage your calendar. Here’s where people still get stuck:
- One account. Claude connects one Google account at a time. Your work calendar, your personal one and the client calendar you were added to don’t come together, and Outlook calendars aren’t part of it.
- It asks before it acts. By default, Claude asks for your approval before each change it makes on your behalf, per Anthropic’s help page.
- Claude’s own automation can’t count on your calendar. People reported that Claude Code’s cloud scheduled tasks don’t list the Google Calendar connector, even when it shows as connected. The bug report sat for ten weeks without a fix and was closed for inactivity on October 28, 2026.
- Nothing happens when a meeting changes. A client books, cancels or runs late, and Claude waits for someone to ask.
How Carly fixes it
- Every calendar at once. Carly connects every Google and Outlook calendar you have and finds times across all of them.
- Booking pages. Share a booking link and Carly fills the slots you choose.
- Triggers. Carly acts the moment something lands on your calendar, and on any schedule you set. It will even call you with your day.
- Everything else. Carly connects to thousands of apps, so a meeting can update HubSpot, start a Zoom, or text the person you’re meeting.

Triggers you can set up from Claude
Type these into Claude. Each one becomes a trigger that runs in the cloud, whether or not you’re in the chat:
- “When a meeting with a new client gets booked, send me a prep brief the night before.”
- “When someone cancels, email them three new times from my calendar.”
- “When a meeting ends, send the follow-up email and log the notes in HubSpot.”
- “When something gets booked over my lunch hour, move it and tell me.”
- “Call me every weekday at 8am with my day.”
- “When a meeting has an address, block the drive time before it.”

Ask Claude to schedule
Carly also lets Claude run your calendar in the chat:
- “Find 30 minutes next week for Michael, Claire and me, and send the invite.”
- “Move my Thursday 3pm with Josh to Friday morning and let him know.”
- “Cancel everything after 4 on Friday and tell the attendees.”
- “What does my week look like across my work and personal calendars?”

What Claude’s Google Calendar connector does on its own
Anthropic’s Google Calendar connector is a good calendar assistant inside a chat. Turn it on in Claude under Customize, then Connectors, and sign in with Google. Then Claude can:
- Book events from a sentence: “Put a 30-minute review with the team on Thursday at 2.”
- Move and cancel events you already have.
- Find open time on your calendar and suggest slots.
- Answer questions about your week, with links back to the events it used.
By default it asks before each change, and on Team and Enterprise plans the owner decides whether members can let actions run without asking (Anthropic’s help page). It works when you ask it something, for the one Google account you connected.

See what people say
"Before Carly, I relied on a Calendly link, but the whole process felt impersonal and not very professional. Carly changed that by handling all the back-and-forth, so I'm no longer stuck in endless email threads trying to line up schedules.
Now Carly reaches out to candidates, shares my real-time availability, lets them pick a slot, then sends a Zoom link and drops it straight into my calendar. She sends reminders to both of us before each call, which has significantly reduced no-shows and last-minute confusion.
On top of scheduling, Carly acts like a full executive assistant, sending me my schedule the night before so I can prepare for each call. It reminds me of the old x.ai assistant, but Carly is noticeably smarter, faster, and better suited to my healthcare recruitment business."
