Callum is an AI calendar assistant built for teams using Google Calendar. It understands multi-person meetings, shared availability, and real-world scheduling constraints. Use natural language to schedule, reschedule, and manage meetings without back-and-forth emails or manual calendar admin. Boost Callum knowledge by connecting your CRM, ATS, CSM apps. Available on Web, iOS, Slack and ChatGPT (soon).

First calendar AI assistant which works properly 🎉🎉🎉 I'll soon stop typing and scrolling and only use voice, such a relief. My favorites are different summaries, searching, adding calls quickly, reminders, and color-coding. I still need to test accessing data via integrations.

@petr_antropov1 Thanks Petr! 🙌 Voice-only life is the dream – soon we'll all forget how to type 😅 Let me know how the integrations go – happy to help if anything acts up 🙏
Turning scheduling into a conversation instead of a UI maze is a smart move.
Looking forward to the Slack and ChatGPT integrations.

@anupamsingh0211 Appreciate it! Slack is coming soon – will keep you posted 🙌
Going to try this for my challenge — scheduling across time zones and multiple teams, 15 emails deep, trying to find 30 minutes that works for everyone.
If it handles multi-person availability well, that alone is worth it. Congrats on the launch, Nick.

@kristaps_lapins1 That's exactly what it's built for! Let me know how it goes – happy to help if anything trips up 🙏
