@nick_ustinov1 Hi Nick, Congrats on the launch. Cool little tool. Any chance of support for MS teams?
@zolani_matebese Yep, that's coming – working on Microsoft Outlook integration!
@nick_ustinov1 Let's gooooo! Excited to try this.
@zencachola Saves 4-5 hours per week, for busy folk :) Let me know how it goes!
@curiouskitty Great question! The switching trigger is usually when scheduling stops being simple - coordinating across multiple people, time zones, or needing context from other tools (CRM, ATS). Booking links work great for 1:1 external meetings, but fall apart with group availability or internal coordination.
What we intentionally don't do: auto-scheduling your entire day or moving things around without asking. Callum is your assistant, not autopilot – you stay in control.
Going to try this for my challenge — scheduling across time zones and multiple teams, 15 emails deep, trying to find 30 minutes that works for everyone.
If it handles multi-person availability well, that alone is worth it. Congrats on the launch, Nick.
@kristaps_lapins1 That's exactly what it's built for! Let me know how it goes – happy to help if anything trips up 🙏
Turning scheduling into a conversation instead of a UI maze is a smart move.
Looking forward to the Slack and ChatGPT integrations.
@anupamsingh0211 Appreciate it! Slack is coming soon – will keep you posted 🙌
Happy to see the product here with updated features that users always wanted. Kudos to the whole team on launch
@sachin_shajan Thanks! Glad it resonates 🙌"
First calendar AI assistant which works properly 🎉🎉🎉 I'll soon stop typing and scrolling and only use voice, such a relief. My favorites are different summaries, searching, adding calls quickly, reminders, and color-coding. I still need to test accessing data via integrations.
@petr_antropov1 Thanks Petr! 🙌 Voice-only life is the dream – soon we'll all forget how to type 😅 Let me know how the integrations go – happy to help if anything acts up 🙏
the natural language input looks way faster than clicking through grid views. can I use voice commands for complex recurring events, like "every third Tuesday"?
