How to Use Gemini Memory and Reminders

Name: Google Pixel Watch 4
Brand: Google
Availability: PreOrder
Rating: 4.8 (1250 reviews)

Gemini stores temporary information and sets contextual reminders through voice commands. This is perfect for quickly capturing details you'll need later without typing or opening apps.

Storing Information

Tell Gemini to remember details you'll need to recall later.

Parking: Say Remember I parked on level 3, section B or Remember I'm in parking spot 142.
Lockers/Numbers: Say Remember my locker is number 18 or Remember my table number is 7.
Temporary Codes: Say Remember the door code is 4521 for temporary access information.
Meeting Details: Say Remember the conference is in room 305 when you need the info later.

Best for Temporary Info

Use Gemini memory for information you need short-term. For permanent storage, use notes or calendar events instead.

Retrieving Information

Ask Gemini to recall what you stored earlier.

Direct Questions: Say Where did I park, What's my locker number, or What room is the meeting in.
General Recall: Say What did I ask you to remember to see all stored items.
Specific Topics: Say What did I tell you about parking to narrow down to specific stored info.

Setting Reminders

Create reminders triggered by time or location.

Time-Based: Say Remind me to call mom at 3 PM or Remind me to take medicine in 2 hours.
Location-Based: Say Remind me to buy milk when I get to the store or Remind me to grab my badge when I get to work.
Recurring: Say Remind me to drink water every hour or Remind me to stretch every 30 minutes.
Combined: Say Remember I need to return these headphones and remind me next Tuesday.

Managing Reminders

Control and modify your existing reminders.

View Reminders: Say What reminders do I have or Show my reminders for today.
Cancel: Say Cancel my 3 PM reminder or Delete the reminder about calling mom.
Modify: Say Change my reminder to 4 PM instead or Make my reminder for tomorrow instead.

Practical Uses

Memory and reminders work best in these scenarios.

At Events: Remember parking location, seat number, or locker assignment at gyms, concerts, or conferences.
During Activities: Store quick thoughts during walks or workouts when note-taking isn't practical.
Daily Logistics: Set location-based reminders for errands you'll do throughout the day.
Work Tasks: Combine memory storage with reminders: Remember the report is due Friday and remind me Thursday morning.

Voice-First Advantage

Memory and reminder features are especially valuable on watches since typing is impractical. Speak naturally and Gemini handles the storage and retrieval.
