## What is Callum?

Callum is the fastest way to manage your Google Calendar. Just say what you want — Callum understands natural language and handles the rest.

SCHEDULE IN SECONDS 
Stop clicking through menus. Just speak or type naturally:
• "Schedule a call with Sarah tomorrow at 2pm"
• "Block 2 hours for deep work on Friday"
• "Add a dentist appointment next Tuesday morning"

From thought to calendar in under 5 seconds.

FIND TIME WITH ANYONE
Scheduling with multiple people? Callum checks everyone's availability and finds slots that work for the whole group. No more back-and-forth emails.

Just ask: "When can I meet with Alice and James this week?"

RESCHEDULE INTELLIGENTLY
Need to move a meeting? Callum checks all participants' calendars and suggests new times that work for everyone. Attendees get notified automatically.

ASK YOUR CALENDAR ANYTHING
More than scheduling — a calendar that understands context:
• "What's on my calendar this week?"
• "When did I last meet with the design team?"
• "Do I have any free time tomorrow afternoon?"
• "How many meetings do I have this month?"

ALL THE ESSENTIALS
• Create events with natural language
• Update time, title, location, or attendees
• Delete events with confirmation
• Search past and future events

WORKS WITH GOOGLE WORKSPACE
If you're on a company Google Workspace account, Callum can check colleagues' calendars automatically — most organizations share availability internally by default.

PRIVACY FIRST
We don't store your calendar data. Callum talks directly to Google Calendar when you ask it something. Your events stay with Google, not us.

VOICE INPUT
Speak naturally to create and manage events. Perfect for when you're on the go.

Connect your Google Calendar and start managing your schedule with AI.
