Does Reclaim AI replace Google Calendar?

No, Reclaim does not allow you to create/edit/manage calendar events within the app. They are a layer atop your calendar, so with Reclaim, you'd continue using Google Calendar, Notion Calendar, or even Motion as your calendar app and daily planner.

Which Is Better Reclaim or Motion?

Reclaim is not a calendar app, project management tool, or task management tool, while Motion is all of those things. Motion is made for business owners, teams, and people who want a powerful tool to manage their projects and time. Reclaim helps individuals within larger organizations "protect" more of their time" from being booked over with meetings and get more focus time for work. So, which category do you fit into?
