Callum Introduction

Callum is an AI-powered calendar assistant that transforms calendar management by enabling natural language interaction with your schedule. It integrates with Google Calendar to let users create, reschedule, and optimize events through simple voice or text commands, eliminating manual calendar navigation and saving significant time.

Key benefits include:

  • Group Scheduling: Automatically finds available time slots that work for all participants by checking everyone's calendars, eliminating back-and-forth emails
  • Natural Language Processing: Schedule meetings in seconds by speaking commands like "Schedule quarterly planning Thursday at noon with Jim, Marta and Alice"
  • Contextual Meeting Preparation: Integrates with CRMs (HubSpot, Salesforce) and hiring tools (Greenhouse) to pull relevant context for meetings
  • Intelligent Rescheduling: Finds alternative times that work for all attendees and automatically notifies participants of changes
  • Calendar Insights: Ask questions about your schedule, add meeting agendas, or prepare for interviews through conversational queries

Perfect for busy professionals, sales teams, and recruiters who want to automate calendar management and focus on high-value work.
