Callum
Callum is an AI calendar assistant that brings smart, natural-language control to your work schedule so you can manage your calendar faster and with less friction by speaking or typing what you want done instead of navigating calendar UIs. It works with Google Calendar (with Outlook support coming) and lets you schedule, reschedule, update, delete, and search events simply by telling Callum what you need, helping you find time with individuals or groups by checking everyone’s availability and suggesting optimal slots without endless emails. Beyond basic scheduling, Callum understands context, pulls in details when connected to tools like HubSpot, Greenhouse, and other CRM/ATS systems, and helps you prepare for meetings with relevant historical and deal information so you’re ready before every call. You can also ask conversational questions about your calendar, such as how much free time you have this week or when you last met a contact.
