Hi Product Hunt! I'm Manuel, the maker. I built NOTABR because of one stubborn problem: students know they should study, they just don't come back tomorrow. So instead of another quiz app, the core here is a league. You pick a subject (maths, Portuguese, history, geography, physics, chemistry, biology or English) and get placed in a division from Bronze to Legend. The season resets every Monday at 00:00 UTC: the top 7 of your division are promoted, the bottom 5 are relegated. Points are 10 per correct answer plus a speed bonus - but answering in under 5 seconds gives you zero bonus, so button-mashing gets you nowhere. The part I'm most proud of is the boring part. After the AI writes a question, a second pass asks the AI to solve it blind, without seeing the answer key. If the two disagree, or the question is flagged as ambiguous, it gets thrown away. In an app that teaches, a wrong answer key is worse than one question less. Free to start (5 quizzes a day), installable as a PWA, and bilingual PT/EN. Being honest: this is early and what I really want is feedback on the loop itself. If you try it, I'd love to know whether you came back on day two - and if you didn't, what made you not bother. That's the answer I need most right now. Thanks for taking a look!
