Hey PH! 👋 Maker here. CognitIO started from a personal frustration — I was spending more time highlighting and re-reading PDFs than actually learning from them. Study sessions felt inefficient, and I knew AI could do better than just "summarize this." So I built CognitIO to turn any PDF into a full study toolkit: structured summaries, flashcards, Q&A tests, and a chat interface that lets you actually talk to your document. The goal was to make deep understanding faster, not just reading faster. The biggest challenge was getting the AI to produce summaries that feel structured and readable — not just a wall of text. We ended up building a custom markdown parser that renders headings, bullets, and sections in a clean, editorial style. Would love to hear how you use it and what you'd want next. Drop your feedback below — every comment shapes the roadmap. 🚀
