Callum

4.5

Callum is an AI-powered calendar assistant designed to take the busywork out of scheduling, coordinating, and running meetings. Instead of juggling time zones, comparing calendars, and writing reminders, you simply tell Callum what you want in natural language—“Find 30 minutes with the sales team next week” or “Reschedule my 1:1 with Anna to Thursday afternoon”—and it handles the rest. Connected to your existing calendar stack, Callum intelligently proposes times, avoids conflicts, and keeps everyone aligned. Built for teams, Callum understands working hours, preferences, and priorities across multiple people, so the meetings that matter most always come first. It adapts to your habits over time, learns who you meet with regularly, and can automate recurring workflows like weekly check-ins, project standups, or customer calls. From startup founders and team leads to operations and customer-facing roles, Callum helps you spend less time scheduling and more time doing meaningful work. With a free plan and a simple setup, you can start using AI to manage your calendar in minutes—no complex onboarding required. Let Callum handle the logistics, so you and your team can stay focused on the conversations that move your business forward.
