Pupil is a beautiful, open-source flashcard app that helps you remember everything. Type a topic and AI drafts a deck you approve card by card, or drag in your Anki decks. FSRS spaced repetition brings each card back right before you'd forget it, with stats that surface weak spots. A calm, keyboard-first desktop app for macOS, Windows, and Linux. Free and MIT-licensed: no account, no subscription, and your cards stay on your machine.

Hi everyone! I'm excited to meet the Product Hunt community and to have the privilege of sharing a project that has been a real labour of love for me.
Having battled ADHD all my life, I'd be the first person in any room to forget literally anything and everything. Poems in primary school. Birthdays. Appointments. Language syntax. You name it. The older I got, the more embarrassing these moments became.
A year ago today, I set out to conquer one of my biggest fears: LeetCode. A few months in, I noticed that, as usual, I'd started to forget some of the earlier algorithms I had already spent blood, sweat, and tears practicing. It felt devastating. My mind was a sliding window: every new problem pushed an old one out.
That was when I discovered spaced repetition and Anki. As awesome as the open-source concept was, I found myself hating every moment of using it. It looked old and clunky, and nothing about it felt flowy, calm, or intuitive. Every study session ended up feeling like an uphill battle.
That brings us to today, and to Pupil. It's a fully open-source, beautiful, AI-assisted study tool that runs on your Mac, Linux, or Windows desktop. It's fast and tiny. It's opinionated. It's meant to help you not just create and store cards, but actually remember to study every single day.
There's still lots to do, with a mobile companion app on the horizon. But for what it's worth, I hope you get a lot of value out of it as it is today.
Looking forward to hearing your feedback :) Try it. Star it. Break it. Fork it.
Next up: Althar, an open-source IDE for coding agents, on 5 Dec. You'll fall in love with this one.
