rivva is an AI task manager and calendar planner that organises your day around how well you can actually think and work, so demanding tasks land when your focus is strongest rather than wherever there happens to be space.

Most productivity tools only model activity; they track tasks and meetings, but ignore the limits of human attention. rivva works from a fuller picture by combining what you need to do with how much capacity you have to do it, using your tasks, email, and calendar alongside signals from sleep, energy patterns, and cognitive load.

Tasks are captured automatically from email, calendar, and direct input, then scheduled against your real availability and natural energy rhythm, so work is arranged to fit your mind rather than forcing it to fit the calendar.

What rivva does:

- Task management: Capture, organise, and schedule tasks in one place

- Inbox: Extracts tasks from email, including meeting notes, Jira issues, and Notion comments

- Energy insights: Connect your wearable and see when you are naturally sharpest

- AI scheduling: Plans work around availability and energy patterns

- Nia (AI chat): Create tasks, plan your week, set up meetings, or ask for guidance

- Planner: Multi-calendar view with time-blocking.

We built rivva for founders, executives, and high-output professionals who already work hard and want a system that respects how the mind actually works.
