About rivva
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. 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 and calendar alongside signals from sleep, energy patterns, and cognitive load.
