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).








I generally prefer my digital assistants to be as Spartan as possible; unnecessary complexity in either design or function tends to result in a tiresome learning curve. Callum, however, manages to be considerably more ambitious than my typical expectations while remaining surprisingly approachable for the uninitiated — I shall be watching for further updates!
PS I particularly appreciate the 'Made for busy people' sentiment :)
Congrats on the Callum launch! :) Scheduling is one of those “small” pains that quietly burns hours.
Personally, I’d use it for team scheduling in Google Calendar when a simple meeting turns into a 12-message thread, especially for reschedules and multi-person availability.
When you say “real-world scheduling constraints”, what does that cover, like working hours, buffers/travel time, and rules like “no meetings after X”?
Multi-person meeting scheduling is where most calendar tools tap out. They can block your time, but they dont reason about everyones constraints at once. Curious how Callum handles edge cases like recurring conflicts or attendees across different orgs with limited calendar visibility.
This has been a lifesaver for our team’s chaotic scheduling—being able to just type a quick natural language request to book a meeting with 5 people is such a relief! I’m curious: can it automatically detect and avoid overlapping time slots across multiple shared calendars in our workspace?
Finding time slots that work for the whole group is the most frustrating part of scheduling - love that Callum handles this automatically!
The natural language approach makes so much sense. "Schedule call with Nick tomorrow 11:30am" is exactly how we think about meetings, not clicking through calendar UIs.
Does it handle timezone differences for remote teams? That's always been my biggest headache with group scheduling.
Congrats on #5 - well deserved! 🎉
