Lumer is a gentle AI voice companion that calls you at the time you agreed on and keeps you company while you start. These notes explain how it works, who it’s for, and why we built it the way we did.
Notifications are easy to swipe away. A call at the time you agreed on feels different, and that’s on purpose.
Summary
A gentle call is harder to ignore than a banner, and it brings company with it, which is what actually helps you start.
Lumer is an AI body double on your phone. You choose a task and a time. When that time comes, Lumer calls. A calm voice says hello, helps you find a small first step, and then stays with you while you take it. It can talk you through the next step, or stay quietly in the background while you work.
It’s made for anyone who finds starting hard: teens 13 and up and adults, including many people with ADHD. It isn’t a medical tool, and it doesn’t replace care from a doctor or therapist. It’s company, arriving on time.
Notifications are easy to swipe away, and even when they land, they can only tell you to start. A call asks for a moment of your attention and brings company with it, which is often what actually helps. We explain the thinking in why Lumer calls you instead of sending a notification. If you’d rather not take calls, any task can use an alarm or a notification instead.
The idea behind Lumer is body doubling: many people find it easier to begin when someone else is there. Usually that someone is a friend, a sibling or a study partner, and they aren’t always free at four o’clock on a Tuesday. Lumer is there for those moments.

Lumer doesn’t keep streaks, hand out scores or ask whether you finished. If today isn’t the day, you can decline the call and nothing bad happens. It will simply call again next time. We made it this way on purpose, because pressure tends to make the wall higher. A reminder that makes you feel guilty is easy to start avoiding. A friendly voice that turns up on time, and doesn’t mind if you’re not ready, is easier to keep saying yes to. Here’s why streaks can backfire for ADHD brains.
In short, anything where knowing what to do isn’t the problem, but starting is. That moment is the focus of why starting feels harder than doing.
