GenCurio - AI creates personalized textbooks on any topic in mnutes

Hey Product Hunt! 👋 I built GenCurio because I was frustrated with how long it takes to create structured learning materials. Whether you're an educator designing a course or a self-learner diving into a new topic, writing a well-organized textbook from scratch is incredibly time-consuming. GenCurio automates the entire pipeline — from topic research and outline generation to writing polished chapters with inline citations. You just type in a topic, and the AI agent handles the rest: researching authoritative sources, designing a logical chapter structure, and writing each section with proper references. Key features: • AI-powered research pipeline that finds and evaluates sources • Automatic outline generation with logical learning progression • Chapter-by-chapter writing with real-time streaming • AI-generated cover art for each book • Built-in rich text editor for reviewing and editing content The tech stack: Next.js 15, Vercel AI SDK, OpenRouter for multi-model AI, and Supabase for storage. Would love to hear your feedback! What topics would you create a textbook about?
