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.
Hi Product Hunt 👋🏽
I’m Peace, co-founder of rivva.
Like many ambitious people, I built a reputation for getting a lot done. Over time, that ability to push through became both my strength and my weakness. By 29, I had burned out twice.
That forced me to rethink productivity. I started studying how cognitive energy works and how much it is shaped by sleep, context, and timing.
I reached one clear conclusion: productivity is not about squeezing more out of time; it is about managing energy. Focus, creativity, and judgement rise and fall through the day, and our best work happens when effort matches that rhythm.
That is why we built rivva.
rivva brings your email, tasks, and calendar into one system, then schedules work based on your energy patterns and real availability. The aim is simple: help you get important work done without overload.
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.
I would genuinely love to hear what you think. Try it out and tell us what feels useful, confusing, or missing.
This solves a problem most people only notice after it’s too late.
The idea of intervening only at the moment of sending — without rewriting or storing anything — feels genuinely thoughtful.
Hi, as freelancer, I absolutely love the energy-based scheduling idea – it’s a game-changer for sustainable productivity! I’ve been using Ultrahuman Ring for 3+ years and its data flows great into Apple Health, but a direct native integration would be amazing since building on top of Health data feels indirect. Any plans for Ultrahuman support? Thanks 🙏🏻
Congratulations on the launch! Can you set different modes? For example, today I want a relaxed workday, so I tell your AI, and it schedules only a small number of meetings for me?
I know that most planners assume I can focus the same way all day, which just isn’t true, so planning work around energy instead of willpower feels more honest, especially when meetings and surprises blow up the schedule anyway.
What I really like is that the goal isn’t a “perfect day,” just less replanning and mental overhead. Congrats on the launch.
Hi,
I really like the idea behind Rivva the step-by-step planning approach feels thoughtful and useful.
I noticed that the free trial allowed planning only once, which made me curious about the workflow. If I want to change something later (for example, a routine task or schedule preference), do I need to go through all the steps again, or is there a way to update things directly using a prompt or quick edit?
Just wanted to understand how flexible the experience is for frequent changes.
Thanks, and great work on the product.
Congrats on the launch, it feels like the clarity filter for the internet I didn’t know I needed. This would be very useful esp. for females since we're quite affected by our natural cycles for energy etc. Looking forward to seeing this grow!
Love the concept! Energy‑based planning isn’t common in mainstream tools, and it feels like a meaningful direction. Excited to see how this evolves, especially how accurate the energy model can get over time. An API‑first approach could open up some really interesting ways to experiment with tracking and personalization.
Very cool app! I just started my free trial on rivva and have a few questions when using it. For now I must connect it with my calendar, however many of my calendars are public ones (shared with other people) so I don’t want to make any edits to it. It would be great if rivva can have its own calendar system so I can have a separate calendar inside the app just for myself. Another problem is that I can’t creat a task on my calendar: it keeps saying that there are no free time blocks on mine but I’m sure there are. It might be a bug that needs to be fixed.
Congrats on the launch! Anchoring productivity around energy rather than time feels very aligned with how people actually work. How does rivva adapt when someone’s energy patterns change over weeks or months, especially as routines, workloads, or sleep quality shift?
Relevant for times like this where social scrolling have left humans with less attention span and struggle committing stretch of hours to get stuff done. Procrastination is now the order of the day.
Would be super good to tap into my rhythm get work done in bits according to my mood/energy.
Wow, rivva looks amazing! The energy-based scheduling is such a cool concept. Im curious, how granular can I get with defining my personal energy patterns?
Congrats on the launch, y'all! I love any tools that help you find when your peak times are for work. How does rivva determine what my peak energy/productivity levels are? Can I categorize the "kind" of work a task is so it gets scheduled during an appropriate time? For example, for me, "low energy" tasks could be replying to e-mails or updating work tasks, "high energy" tasks would be heads-down coding tasks or other deep work.
Awesome work! I look forward to checking it out!!
I spent a lot of December trying to find a tool exactly like this. A tool that works according to my day because every hour is different. Congratulations on your launch! Definitely checking it out
The shift from time management to energy management is so needed - really resonates with the burnout story behind founding this. Most schedulers just treat us like machines that can context-switch infinitely. Curious about the learning curve: does Nia start with wearable data from day one, or does it learn your patterns over time through manual input first? Also wondering how it handles the unpredictability - like when a surprise meeting tanks your afternoon focus.
congrats! can you tell more about what kind of use cases do you cover? is it for personal use or work?
I’ve experienced rivva since its beta, and it’s been great seeing how much it’s matured by launch. As a designer, I really appreciate how it reframes productivity around clarity and capacity, not hustle. Energy-aware planning feels like the right next step for this category. Well done 👏
I totally love this product! I signed up 3 days ago and it's quickly become a ritual, love how it surfaces tasks that I am almost forgetting so I don't drop the ball!
Nothing brings me more joy than building with a team that's solving real problems.
rivva has helped me become more aware of how my energy affects my output and that's something I never considered before. The best part of rivva for me is Smart schedule. I don't need to think of when to do work, I just need to toggle a button and rivva does it for me. This way, I spend more time actually working than planning to work.
Love the energy-based approach! Burnout is real, and most planners ignore it completely.
When Nia auto-schedules tasks, does the user get a chance to review/approve the plan before it's set? Or does it just go straight to the calendar?
