OnlyBusy vs Motion
Last updated 3 October 2026
Motion is an AI planner for projects, tasks, and the calendar. OnlyBusy does not plan work. It writes a private Busy event so a client's Outlook or Google scheduler sees the hour as taken.
At a glance
| Comparison | Other approach | OnlyBusy |
|---|---|---|
| What it is for | AI projects, tasks, calendar, meetings, and docs, as listed on the pricing page. | A private Busy event on each calendar you connect. |
| Scheduling Assistant | Motion works on the calendar it is planning. A client's separate tenant is a different calendar. | The Busy event is written into each connected tenant. |
| Event details | The planner creates and moves work on the calendar it manages. | The other calendar gets the label you set. The source title is not stored. |
| How you connect | You use Motion as the planner, with its own apps. | Personal sign-in for Google Calendar and Microsoft 365. |
What they are for
Motion bundles an AI task and project planner with calendar and docs. As of 3 October 2026, the pricing page lists AI Projects and Tasks, AI Calendar and Meetings, and AI Docs on Pro AI and Business AI.
You pick it when you want software to plan the work, not only to mark an hour taken in another tenant.
What OnlyBusy writes
OnlyBusy writes a private Busy event. It does not rank tasks, plan a project, or rewrite your week.
The label can differ per calendar. Guests, notes, and location stay on the source calendar.
Who should stay with them
Stay with Motion when you want an AI planner for tasks and projects, with the calendar features listed on their pricing page.
That product is larger than availability. The extra surface is the reason to keep it.
Who should add OnlyBusy
Add OnlyBusy when the missing piece is a Busy label inside a client's Microsoft 365 or Google calendar.
Motion can plan one working calendar. It is not a substitute for a private block in a tenant you do not administer.
