Callum
Callum is an AI-powered calendar assistant designed specifically for teams on Google Calendar. It goes beyond simple scheduling links by understanding natural language commands, multi-person availability, and complex constraints. Instead of navigating calendar grids, users can simply tell Callum to “find time” via chat, and the AI handles the coordination, conflict resolution, and invites. It aims to act as a proactive executive assistant rather than just a passive scheduling tool.
Key Features
- Natural Language Scheduling: Book, reschedule, or query your calendar using conversational commands (e.g., “Find 45 mins with the Design Team next Tuesday”).
- Smart Team Coordination: Instantly analyzes availability across multiple team members to find conflict-free slots without playing “calendar tetris.”
- Context-Aware Intelligence: Can connect with CRM, ATS, and CSM tools to understand who you are meeting and prioritize accordingly.
- Cross-Platform Access: Currently available via Web and iOS, with Slack and ChatGPT integrations on the immediate roadmap.
Use Cases
- Team Meeting Coordination: Instantly find a slot that works for 5+ internal stakeholders across different time zones.
- Sales & Recruitment: fast-track demo or interview booking by letting the AI handle the back-and-forth directly from your request.
- Calendar Management: Quickly reschedule conflicting events or move meetings using simple text commands on the go.
Pros & Cons
- Pros: Completely removes the manual friction of clicking through calendar grids; “Free during beta” pricing makes it accessible; handles complex group logistics better than standard “booking links.”
- Cons: Deep integration is currently limited to the Google Calendar ecosystem (no full Outlook support yet); Slack and ChatGPT interfaces are announced but not yet fully live.
Pricing
- Free (Beta): Currently free to use at launch as the product gathers user feedback.
- Future Pricing: Likely to introduce tiered paid plans for enterprise features and advanced integrations post-beta.
How Does It Compare?
vs. Task & Project Automation
- Motion: Focuses heavily on project management and auto-scheduling individual tasks into gaps. It is more expensive ($19–$34/mo) and complex, ideal for users who need a to-do list combined with a calendar.
- Reclaim.ai: Best for “defending” your time. It excels at auto-scheduling habits (like “Lunch” or “Focus Time”) and syncing personal/work calendars. It is less focused on the “natural language command” workflow than Callum.
vs. Team Optimization
- Clockwise: An enterprise-grade tool that optimizes existing schedules by moving flexible meetings to create long blocks of focus time. It is passive optimization, whereas Callum is an active scheduling agent.
vs. Scheduling Agents
- Scheduler AI: A direct competitor in the “text-to-schedule” space. While robust, Callum differentiates itself with a more modern, app-centric interface and a focus on internal team velocity specifically for Google Workspace users.
Final Thoughts
Callum enters a crowded market with a distinct “interface-first” approach. While tools like Motion and Reclaim try to optimize what is on your calendar, Callum simplifies how you put things there. For teams tired of the “find a time” dance, its natural language capability offers a frictionless, human-like assistant experience that feels faster than manual drag-and-drop. It is a “must-try” for Google Workspace power users while it remains in its free beta phase.
