How to Create Reminders with ChatGPT and Google Gemini

Stay on top of your tasks by combining the power of ChatGPT with Google Gemini’s native reminder features. This post will show you how to set up automated reminders via ChatGPT and how to use Google Gemini (through Google Assistant) for instant alerts.

Why Automate Reminders?

Automating reminders saves time, reduces mental clutter, and ensures you never miss an important deadline. By pairing ChatGPT’s flexible prompt responses with external tools—or by leveraging Google Gemini’s built-in reminder capabilities—you can effortlessly manage personal and professional to-dos.

1. Automating Reminders with ChatGPT

ChatGPT doesn’t have a built-in reminder system, but you can create workflows that push events into your calendar or task manager.

A. Using Zapier to Connect ChatGPT and Google Calendar

  1. Sign up for Zapier and connect your Google Calendar (or another calendar app).
  2. Create a new Zap with:
    • Trigger: “New ChatGPT Message” (requires the ChatGPT–Zapier plugin).
    • Action: “Create Detailed Event in Google Calendar.”
  3. Format your prompt in ChatGPT like this:textCreate reminder: [Task], [YYYY-MM-DD HH:MM]
  4. Send the prompt to ChatGPT. Zapier will read the output and add an event to your calendar automatically.
  5. Customize the JSON output (optional) so ChatGPT returns:json{ "title": "Submit monthly report", "date_time": "2025-09-10T09:00:00", "calendar": "Work" } This makes it easy for Zapier to map fields.

B. Generating an .ics File Directly

If you’d rather not use Zapier:

  1. Ask ChatGPT to output an iCalendar (.ics) file:textBEGIN:VCALENDAR VERSION:2.0 BEGIN:VEVENT SUMMARY:Pay rent DTSTART:20251001T090000Z END:VEVENT END:VCALENDAR
  2. Download and import the .ics file into Google Calendar or your preferred calendar app.

2. Creating Native Reminders with Google Gemini

Google Gemini, integrated within Google Assistant, lets you set reminders by voice or text—and syncs them seamlessly to your Google account.

A. Voice Commands

On any device with Google Assistant:

“Ok Google, remind me to call Sarah tomorrow at 2 PM.”

Google Assistant will confirm and add it to your Google Calendar or Google Keep, depending on your settings.

B. Text Commands in Gmail or Google Chat

  1. Open the Google Gemini sidebar in Gmail or Google Chat.
  2. Type:textCreate reminder: Send project update, 2025-09-08 10:00
  3. Gemini will show a “Confirm” button—click it to add the reminder.

C. Reviewing and Editing Reminders

  • Open Google Calendar to see all scheduled reminders.
  • If you prefer Google Keep, adjust your Google Assistant settings to save reminders there.

Pro Tips for Smooth Reminder Management

  • Standardize your format. Always use Task – YYYY-MM-DD HH:MM to avoid misunderstandings.
  • Use multiple calendars. Create separate calendars in Google Calendar (e.g., “Work,” “Personal”) and specify the calendar in your Zapier mapping or Gemini command.
  • Set recurring reminders. In Gemini, say “repeat every Monday,” or in Zapier, configure event recurrence when creating the calendar event.

By combining ChatGPT’s prompt flexibility with Google Gemini’s native reminder system, you’ll never miss an important task again—automating the mundane so you can focus on what really matters.
