otto vs
sunsama.
Sunsama is a daily planning tool. It pulls your tasks from Asana, Linear, Gmail, and Notion into a single day view and walks you through a daily planning ritual to decide what you will actually do that day. The category is the daily planning ritual. It gives you a calm, deliberate way to shape the day yourself.
Otto is your chief of staff via text — it watches your calendar and email, decides what matters, and sends three or four messages a day. No app. No dashboards. Just the next move.

how they differ
Sunsama is a ritual. You open it, gather everything from your other tools into one view, and plan the day by hand. The value is the discipline of doing that every morning. If you like planning your own day and want one calm place to do it, Sunsama is built for that.
Otto does not ask you to plan. It reads your calendar and your email, works out what matters, and texts you the next move three or four times a day. There is nothing to open and no ritual to keep up. You get the decision, not the workspace.
If you want to sit down and plan your own day with everything in one view, use Sunsama. If you would rather the day was read for you and sent to your phone, use Otto.
