Create reminder calls with ChatGPT

ChatGPT is great at talking through your day. With the ReminderIt connector, it can also act on it: a request like "call me at 9pm to take my evening medication" becomes a scheduled outbound phone call, not just a note in the chat.

ReminderIt speaks the Model Context Protocol, the same open standard ChatGPT uses for connectors, so setup is a one-time sign-in rather than a fiddly integration.

Add ReminderIt to ChatGPT

In ChatGPT's connector settings, add a custom connector with the URL https://mcp.reminderit.com. ChatGPT opens a ReminderIt OAuth screen; you sign in and approve access, and that is the connection made. No API key changes hands. The exact menu label may differ by ChatGPT version, so look for "connectors" or "add custom connector" rather than a fixed path. A per-client key is created in your account and can be revoked whenever you want at reminderit.com/api-keys.

Ask for a call in plain words

Describe the reminder the way you would to a person: "Set up a recurring call every weekday at 7:45am to leave for work." ChatGPT translates that into a create_reminder call, using a cron schedule for recurring times and a single ISO date-time for one-offs. Because ReminderIt works in IANA time zones, ChatGPT confirms your zone, such as America/Chicago, before it commits the schedule. At the scheduled time ReminderIt phones you and reads the reminder in a warm, natural voice.

Manage everything from the same chat

You do not need a separate dashboard for day-to-day changes. Ask "what reminders are active?" and ChatGPT lists them with list_reminders; "what's coming up?" pulls the schedule with list_upcoming. To change wording or timing, say "reschedule my dentist reminder to Thursday at 3pm" (update_reminder), and to remove one entirely say "cancel my wake-up call" (delete_reminder). It reads as a conversation, but each request maps to a real action in your ReminderIt account.

Keep an eye on your allowance

ReminderIt uses a pooled monthly allowance: five calls on Free and seventy on Pro. A voice call, or a WhatsApp fallback message when a call goes unanswered, each counts as one. Ask ChatGPT "how many calls have I used this month?" and it reads your figure back through get_usage so you can plan the rest of the month. Messaging ReminderIt on WhatsApp to set or manage reminders is free and does not touch this pool.

Safety and revoking access

Everything ChatGPT does happens inside your own account, so it can only see and change your reminders. Adding a family member as a care-recipient starts with a consent call to them before ReminderIt will ever ring their phone. If you decide to disconnect ChatGPT, revoke its key at reminderit.com/api-keys and the connection stops working immediately, without affecting your other clients.
