Snap a photo of your notes. Lexie reads them and builds a practice set from them. Not just flashcards from your highlights, but actual questions an exam would ask. Multiple choice, fill in the blank, open ended questions where AI evaluates your answer and tells you what you missed. Then spaced repetition schedules when to review it all. The exam before the exam, generated from your own material. Works with any subject, even language learning. No account, no ads, photos stay on your device.
Here's how you learn something. You practice and you get it wrong. Someone tells you why. You try again & you keep going until it sticks.
But that's not what happens at school. There aren't enough exercises to go around, and even when there are, there's no guarantee anyone's checking. A teacher with 25 students and 45 minutes is doing triage, not tutoring.
Practice without feedback isn't practice, and the system doesn't have nearly enough of either.
Lexie closes that gap. Take a photo of your biology chapter on the circulatory system and Lexie figures out what an exam would test from it. Then it gives you different ways to practice until you know every valve and vessel. Then spaced repetition schedules when to review it all. So you get everything learning science knows about effective practice without having to know any of it. No surprises on exam day.
Most edtech gives students gamification theater: points, streaks, engagement mechanics that feel good but teach nothing. I stripped that out. Photo determines content, AI determines difficulty, testing reveals gaps. No escape routes. Learning isn't consumption. It's construction. And construction is messy, effortful work.
I designed it so a 10 year old can go from app store to first study set in 30 seconds. No account, no login, no onboarding. All the friction is in the learning, where it belongs. Also, no ads, no trackers, no data selling. Photos stay on device. When you're 16 and need help with geology, you shouldn't have to trade your data for it. Making money from subscriptions, not from students.
Spaced learning is a lost feature with these study apps, devs seem to be forgetting the forgetting curve (ha) identified by Ebbinghaus. ALso the concept of protected data is huge, as is the positioning of simplicity, so that our kids could use it. Love the authenticity Elina. Will be following this one.
Removing streaks and points is a deliberate choice — most apps lean hard on them. Do you see adult learners using this, or is it really built for students preparing for exams?
Been following your journey on LinkedIn. My daughter might soon need something like this (she's 4) and when that time comes, as a parent, I know I'll try Lexie because I know your heart's in the right place making this!
