How to connect your AI assistant to Apple Calendar

The same four steps whichever assistant you use. Each assistant also has its own page for Apple Calendar, below, with what Set up does there and how to check it worked.

  1. 1

    Download Pomeroy.

    Open the download, drag Pomeroy into Applications, and open it. Pomeroy adds an icon to your menu bar and opens a setup window listing every app it can connect. They all start switched off.

  2. 2

    Switch on Calendar.

    macOS asks whether Pomeroy may access your calendar. The prompt names Pomeroy, and nothing is requested until you flip the toggle.

  3. 3

    Choose your AI assistant.

    Pomeroy lists the AI assistants it finds on this Mac. Press Set up beside yours: most take one click, and the rest take a configuration Pomeroy copies for you.

  4. 4

    Ask your assistant.

    Try “What’s on my calendar today?” and a real answer comes back.

Connect a specific assistant to Apple Calendar

Not here: claude.ai, ChatGPT and Grok on the web. Why.

Can my AI assistant see my Apple Calendar?

Yes. Once you switch Calendar on in Pomeroy, your assistant can read today, any day, or a whole range of days, across every calendar your Mac shows. Times come back in your Mac's own time zone.

Can my AI assistant change my calendar?

Yes, when you ask. Your assistant can create an event and change one you name, and it changes only the fields you mention. A recurring event changes only that one occurrence. It cannot delete an event.

Is it safe to connect an AI assistant to Apple Calendar?

Pomeroy reads your calendar on your Mac and sends nothing to a Pomeroy server. What your assistant reads becomes part of your conversation, the same as text you paste in. Calendar starts switched off, and you can switch it off again at any time. Pomeroy is an independent app, not made by Anthropic.

How does Pomeroy compare with other tools?

Other apps also connect an AI assistant to Apple Calendar, and some are free. Pomeroy is the read-mostly one, and the comparison pages set out price, coverage and maintenance for each, with the date the facts were checked: Pomeroy vs iMCP, Pomeroy vs Macuse, Pomeroy vs LMCP, apple-mcp is archived. What should you use instead?.
