Where Sunsama fits best
Guided planning, realistic workload planning, timeboxing, daily shutdown, calendar integration, and pulling work from an existing stack. The daily flow walks through yesterday, today’s work, workload, timeboxing, and a shutdown time.
Sunsama also has native tasks, a backlog, weekly objectives, and a built-in calendar — not only imports.
Where Rio fits best
The assistant is the primary interface, rather than a planning ritual. You talk throughout the day. Tasks, calendar, habits, and notes already live here.
Where they overlap
Both care about a planned, finite day. Sunsama gets there with a ceremony. Rio gets there with a secretary.
Who should choose which
Choose Sunsama when you want a guided ritual that keeps today realistic. Choose Rio when you want to talk to a secretary as the day unfolds.
