Answers vs actions

Most AI assistants give you an answer. Rio can change the plan.

No app to pick. No form to fill. Ask for a reminder, and you get the reminder — not instructions for setting one.

The same request put to a typical AI and to Rio: “Remind me to call Mom tonight.” A typical AI replies “Sure — you can set a reminder for 7 PM tonight” and the conversation stops there. Rio replies “Done! I’ve added it for you” and shows the reminder it made: Call Mom, tonight at 7:00 PM.

When plans change, tell Rio.

A meeting moved. A task didn’t get done. Something got urgent. Say what changed, and Rio updates the plan — no rebuilding your day by hand.

  • “Move this to tomorrow.”
  • “I can’t finish this today. Put it on Friday.”
  • “Find an hour for the presentation.”

You tell Rio“My dentist moved to 11. Move my presentation work.”

Give your brain fewer things to keep track of.

  • What you promised someone
  • Which app something lives in
  • Whether you already moved it
  • What still needs you today

Frequently asked questions

What can Rio's AI assistant do?

Rio can create and change tasks, calendar events, reminders, habits and notes, and lay them out on one day timeline. You describe what is happening; it makes the change where it belongs.

How is Rio different from ChatGPT?

ChatGPT is built to answer questions. Rio is built around your own tasks, calendar, and notes, and changes them when you ask. So a request ends as a reminder or a moved block, not advice you retype.

Can Rio manage tasks and calendar together?

Yes. Rio checks your calendar and your tasks together, so it puts work in a gap that is really free. Tell it a meeting moved and it moves the work too.

Is my information private?

Your data is yours. Rio reads only your own tasks, calendar, and notes — never anyone else's. Our privacy policy explains the rest.
