rivva

rivva is an AI-powered task manager and calendar planner built around a simple truth: your energy, not your to-do list, determines what you can actually accomplish. Unlike traditional tools that merely track activities, rivva takes human attention limits and cognitive load into account when planning your workload.

By integrating with your wearables, rivva forecasts your daily energy peaks and troughs, so it knows when you are primed for deep work and when you need a lighter load. It also automatically captures tasks from your emails, saving you the chore of manual entry and making sure nothing slips through the cracks.

At the heart of it all is Nia, an AI assistant that orchestrates a sustainable daily plan for you. When meetings shift or priorities change mid-day, Nia adapts your schedule on the fly, keeping your plan realistic instead of rigid.

Most importantly, rivva is specifically designed to prevent burnout. It ensures your most demanding tasks land exactly when your focus is strongest, so you end each day productive and drained of stress rather than energy.
