Callum

Callum is an AI calendar assistant that you control with natural language. After you connect your Google Calendar, you can type a request such as 'Schedule a design review meeting with Emma at 2 pm tomorrow afternoon' and it creates the event, including a Google Meet link. Instead of clicking through calendar screens, you describe what you need and confirm the result. It answers in conversation, checks the schedules of everyone involved, and can reschedule when plans change, which removes most of the back-and-forth that usually comes with booking time with other people. The product is currently in the testing phase and can be used for free. It is built for people who spend real time every week coordinating meetings and hunting for open slots.

- Create events from a plain sentence, with meeting links added automatically

- Ask who is free, for example 'What are the available meeting times with Alice and James this week?'

- Move meetings: Callum re-checks the calendars of everyone involved, finds a new time, and notifies participants

- Connect CRM and recruiting tools so you get background before a call

- Ask follow-up questions about your schedule in context, not just create entries

- Busy professionals who arrange meetings throughout the day

- Sales and marketing people who book calls with customers

- Recruiters who schedule interviews and new employee onboarding

Anyone who coordinates time with other people for a living can get value from it, because the tool does the checking and the reminding rather than you.

Callum is still in testing, so features can change or disappear without notice, and the free access offered during this phase is not a long-term promise. Setup runs through Google Calendar, so people who rely on other calendar systems may find support limited. It is a scheduling helper rather than a decision maker, so you stay in control of what actually lands on your calendar, and you should double-check important bookings before you rely on them.
