ChatGPT now works with iCloud Mail and Calendar

What the iCloud Mail and Calendar plugins can do

OpenAI added two plugins to ChatGPT: iCloud Mail and iCloud Calendar. A plugin here is an add-on that lets ChatGPT work inside another service on your behalf.

Since October 27, 2026, ChatGPT can dig through your Apple inbox and change events on your schedule, jobs it could already do for Gmail and Google Calendar users. You describe the task in plain language, and ChatGPT runs the search or makes the edit through the plugin.

Mail finds messages while Calendar checks and edits events

The Mail plugin finds emails and catches you up on the inbox, the Calendar plugin checks your schedule and updates events, and ChatGPT may ask for your approval before it reads or changes anything. In practice, that covers requests like pulling up a receipt from last month, summing up what came in overnight, or moving a meeting to Thursday. OpenAI states the approval step in its help article on connected app accounts, so you may see a prompt before ChatGPT opens your messages or edits an event.

Contacts are read-only, and Reminders is not included

Both plugins can look up contacts but cannot change them, there is no separate Contacts or Reminders plugin, and Gmail or Outlook accounts shown in Apple's Mail app stay out of reach. Contact lookup comes bundled with each plugin, so ChatGPT can find an address when you ask it to locate a message from someone.

The reach stops at iCloud itself. ChatGPT sees only the messages and events tied to iCloud, even though Apple's Mail and Calendar apps can also display Gmail or Outlook accounts.

Every ChatGPT plan gets the plugins, but not on Android

Free and paid users alike can use both plugins on the web, the desktop app and iOS, while Android is missing from OpenAI's list. OpenAI's release notes say the plugins are "available to all ChatGPT plans", and a free account is enough. The same notes name three surfaces and stop there, so Android is not covered as of the October 27 entry.

Pro subscribers get one extra. Dot, OpenAI's agent, can use both plugins on the Pro plan, so tasks it runs for you can draw on your iCloud inbox and calendar.

That reach is wider than ChatGPT's earlier Apple plugin. As covered in ChatGPT Apple Messages: iMessage, SMS, RCS on Mac, that plugin works only in the Apple silicon build of the Mac desktop app and only in Codex and ChatGPT Work chats. Apart from the three surfaces, the iCloud plugins carry no such limits.

You need an Apple app-specific password to connect

An app-specific password is a separate password Apple issues for one non-Apple app, so that app never learns your main Apple Account password. ChatGPT's iCloud connection form asks for an Apple app-specific password instead of sending you to a sign-in page, and your regular Apple Account password should never go there or into a chat. OpenAI's help article spells out both rules: use the app-specific password in the form, and do not paste any password into the conversation.

Two-factor authentication has to be on first

Apple only issues app-specific passwords to accounts protected by two-factor authentication, and you create them at account.apple.com under Sign-In and Security. Two-factor authentication means every new sign-in also needs a code sent to one of your trusted devices. With it turned on, the steps are:

1. Sign in at account.apple.com.
2. In Sign-In and Security, select App-Specific Passwords.
3. Generate a new password and copy it into ChatGPT's connection form.

Apple lets one account keep up to 25 active app-specific passwords. A single password can serve both ChatGPT connections, which matters later when you decide how to remove access.

Mail and Calendar may ask for different addresses

The Mail form wants an Apple-issued iCloud address (@icloud.com, @me.com or @mac.com), the Calendar form wants the email you sign in to your Apple Account with, and those can be two different addresses. Someone who created their Apple Account with a Gmail or work address, for example, signs in to Calendar with that address but connects Mail with their @icloud.com one. Only the address differs between the two forms; both take an app-specific password.

Connect Mail and Calendar one at a time in Settings

Each service is its own connection under Settings > Plugins, so connecting Mail does not give ChatGPT access to Calendar. OpenAI's help article states it directly: installing one plugin does not authorize the other service. Anyone who wants both goes through the form twice, and the setup runs the same way for each plugin:

1. In ChatGPT, open Settings > Plugins.
2. Select iCloud Mail or iCloud Calendar.
3. Enter the address that plugin expects and the app-specific password.
4. Repeat for the other plugin if you want it too.

Once a plugin is connected, you call it from the chat itself. Type @ followed by the plugin name, or open the + menu and pick it from the list.

Disconnecting in ChatGPT leaves the password active at Apple

Removing the plugin in ChatGPT does not revoke its app-specific password, so the password keeps working until you revoke it at Apple. ChatGPT and Apple each hold one half of the connection. Turning off the ChatGPT half stops ChatGPT from using it, while the password itself stays valid on Apple's side.

Changing your Apple password breaks both connections

Changing or resetting your main Apple Account password revokes every app-specific password, so you need a new one and must reconnect Mail and Calendar separately. Apple does this on purpose, to protect the account. Both ChatGPT plugins stop working at the same moment, and so does any other app that signs in with an app-specific password.

To get ChatGPT back, create a replacement password first, then reconnect each plugin with it. OpenAI notes that reconnecting one does not update the other, so you have to fill in both forms again.

Revoke the password at Apple when you stop using it

Revoking the password at Apple is the step that actually cuts access, and it also stops any other connection that shares the same password. The control sits on the same App-Specific Passwords page at account.apple.com, where each password has its own Remove button and Revoke All clears them all at once.

If one password serves both Mail and Calendar, revoking it ends both. Disconnecting does not erase what ChatGPT already holds either: past chats, saved files and memories stay until you delete them yourself.

Other connections using that password may also stop working."／"Reconnect the affected Mail or Calendar connection using a valid Apple app-specific password.

Setup and removal both happen in two places, not one

Both connecting and disconnecting involve ChatGPT and Apple, and skipping the Apple side leaves either a missing password at setup or a live one after removal. Setup starts at Apple, where two-factor authentication and the password come from, and ends in ChatGPT's form. Removal runs the other way: ChatGPT can drop the plugin, but only Apple can revoke the password.

To see what still has access, check Apple's App-Specific Passwords page: it lists every app-specific password that can still reach your iCloud data. An empty plugin list in ChatGPT's settings shows only that ChatGPT no longer uses the password, not that the password is gone.
