Crie provas profissionais em minutos - AI-powered exam gen aligned with Brazil's BNCC curriculum

Hey everyone! I'm Alexandre, a solo dev from Brazil. I built GeraProva because I saw teachers spending 3-4 hours every week just creating exams — time that should go to teaching. GeraProva uses AI to generate validated exam questions aligned with Brazil's national curriculum (BNCC). Every question goes through a triple validation: duplicate detection via semantic embeddings, format checks, and an independent AI "judge" that solves the question blind to verify the correct answer is unambiguous. We've built a bank of 200K+ validated questions covering all subjects from elementary to high school. Would love feedback from educators and edtech folks. What features would make this a must-have for teachers in your country
