Hi Product Hunt community! 👋 We are thrilled to launch Leminno today! Why we built Leminno? Olympiad math preparation is incredibly rewarding, but the current tools make it harder than it needs to be. Students are usually stuck downloading endless past-paper PDFs, scrolling through forums where solutions are either unhelpful or elitist, or using standard AI tools that hallucinate incorrect math. As former competitors, we wanted to build a distraction-free training ground that respects your time and replicates the optimal learning loop: 1. Real Competition Problems Only: No AI-generated math errors. Leminno features 100% human-vetted problems from actual olympiads (IMO, USAMO, Putnam, BMO, etc.) with multiple verified solutions. 2. ELO-Style Adaptive Engine: The platform tracks your skill per topic on a 1–10 difficulty scale and serves problems in your "Zone of Proximal Development" not too easy, not too crushing. 3. Spaced Repetition (FSRS-5): A scientifically optimized daily review queue to plug knowledge gaps and reinforce topics. 4. A Scoped AI Tutor: AI is not the teacher; it’s a study partner. It won't spoil the answer, but it will provide progressive hints, explain concepts on demand, and verify your proof approaches. We’d Love Your Feedback! Leminno is free to start. We would love to hear what you think of the adaptive difficulty and the interface. What features would help you or your students master competitive problem solving? Let’s discuss in the comments!
