Your calendar is a map of how your time is actually spent — who you’re meeting, what’s being discussed, and what decisions are coming up. When you connect Google Calendar to Hyper, it indexes your events along with their descriptions, attendees, and locations, making all of that context searchable through any AI agent. Whether an agent needs to know who attended last Tuesday’s sync, what was scheduled around a major decision, or what’s coming up this week, your calendar data is ready to answer.

​
Connect Google Calendar

1

Open Settings in the Hyper desktop app

Launch the Hyper desktop app and click Settings in the navigation, then select Connections.
2

Click Connect next to Google Calendar

Find Google Calendar in the list of available integrations and click Connect.
3

Authorize with Google OAuth 2.0

A Google sign-in window opens. Sign in with the Google account whose Calendar you want to connect, then grant Hyper the requested permissions. Hyper uses standard Google OAuth 2.0 — your Google password is never stored by Hyper.

Wait for the initial sync to complete

Hyper fetches events within a ±90-day window (90 days before and after today), groups them by day, and indexes them. You’ll see sync progress in Settings → Connections.

What Hyper Syncs

What’s syncedDetails
EventsTitle (summary), description, location, attendees, start/end times
GroupingEvents are grouped by day for efficient retrieval
Time windowFixed ±90-day window — 90 days before and after today
Incremental updatesChanges are tracked via Google Calendar’s updatedMin parameter
Source linksEach event links back to its htmlLink in Google Calendar
Hyper reads calendar events only — it never creates, edits, or deletes any events on your calendar.
For best results, keep event descriptions and attendee lists populated in your calendar. Richer event metadata means agents can answer more specific questions about your schedule.

​
Search Your Calendar with AI Agents

Once your calendar is indexed, your AI agents can search across events within a ±90-day window around today, matching against event summaries, descriptions, locations, and attendee names. Example agent queries: 
What meetings do I have with the design team this week?
Find any events mentioning "budget review" in the next 90 days
Who attended the product sync on March 12th?
Show me all events with Alice this quarter
What was scheduled on the day we launched the beta?
Read all events for next Monday
Find events at the San Francisco office in the next two weeks
What agents can do:
ActionDescription
Keyword searchMatch events by summary, description, location, or attendee name within ±90 days of today
Read dayRetrieve all events for a specific calendar day
Read eventFetch full details of a specific event
Agent search queries are scoped to a rolling window of 90 days before and after today. This keeps results relevant and performant. If you need to surface older events, try reading a specific day directly rather than using keyword search.

​
Reconnect Google Calendar

If your Google OAuth token expires, Hyper will show a Reconnect prompt next to Google Calendar in Settings → Connections.
1

Go to Settings → Connections

Open the Hyper desktop app and navigate to Settings → Connections.
2

Click Reconnect next to Google Calendar

Click the Reconnect button. A Google sign-in window opens.
3

Re-authorize with Google

Complete the OAuth flow. Your previously indexed event data is preserved — Hyper resumes incremental sync from where it left off using updatedMin.
Reconnecting restores the sync pipeline without deleting existing indexed events. Only events created or modified while the connection was inactive will be re-fetched.

​
Disconnect Google Calendar

To remove Google Calendar from Hyper, go to Settings → Connections, find Google Calendar, and click Disconnect. This revokes Hyper’s access token and stops future syncing. Previously indexed event data will be removed from your memory layer.
Disconnecting Google Calendar removes all synced event data from Hyper’s memory layer. If you reconnect later, Hyper will perform a fresh sync within the ±90-day window.
