Hey Product Hunt! 👋 I’m the maker of Cubrain. As a developer and language Learner, I spent way too much time making flashcards instead of studying them. So I built Cubrain to go from lecture PDF to 50 Anki cards in minutes. Most AI wrappers just dump text and hallucinate. Cubrain is different—it uses a coordinate-based extraction engine. It maps the exact visual location of your highlights to ensure the AI understands the full context with zero hallucinations. Core Features: 🎯 Precision Extraction: Extracts text based on visual coordinates (XY mapping). 🧠 Tier Synthesis: Smart batching for high-quality, atomic Q&A. ⚡ Svelte 5 & Spring Boot: Built for speed, reactivity, and real-time feedback (SSE). 📤 Anki Ready: Exports directly to CSV for Anki. I’d love to hear your feedback on the extraction accuracy! You can try the interactive demo directly on the site. Cheers!
