Description
Are you tired of reading endless PDFs and EPUBs only to forget the core concepts a week later? Your brain doesn't need just another PDF viewer with highlighters. You need a system that transforms consumption into creation.
Thread Reader is a next-generation personal knowledge management (PKM) tool engineered for researchers, grad students, and lifelong learners. Built natively for iPad, we’ve shattered the boundaries between reading, note-taking, and drafting. By seamlessly integrating a spatial canvas, infinite handwriting margins, bi-directional linking, and AI-guided learning, Thread Reader turns fragmented highlights into a structured, ready-to-publish manuscript.
Core Features:
【 AI-Generated Knowledge Graphs 】
Don't know where to start with a dense textbook? The moment you import a document, Thread Reader extracts the structural hierarchy and generates a "Dependency Star Map." Navigate complex academic subjects like a skill tree, clearly seeing which foundational concepts you need to master before tackling advanced chapters.
【 Infinite Canvas & Native Apple Pencil Support 】
Never be constrained by narrow PDF margins again. We’ve re-engineered the reading experience by attaching an infinite, transparent whiteboard directly to your documents. Grab your Apple Pencil to sketch diagrams, solve equations, and brainstorm right next to the text. Your ink scrolls perfectly in sync with the page.
【 Spatial Whiteboard & Incremental Cards 】
Read deeply on the left, assemble blocks on the right. Drag and drop brilliant quotes or your own typed insights onto the infinite whiteboard to create free-flowing "Knowledge Cards." Every card retains a strict, unbreakable Anchor ID to its original source. No matter how you rearrange, cluster, or zoom out on your whiteboard, you can always trace a thought back to the exact paragraph.
【 Paper Assembly & Export Engine 】
Transform your scattered whiteboard nodes into a coherent draft. Our assembly engine extracts the logical skeleton of your mind maps and uses AI to weave fragmented cards into flowing academic prose. The best part? All source IDs are automatically converted into standard academic footnotes. Export your work directly to Markdown or Word with a complete, auto-generated bibliography.
【 Insight Timeline & Feynman Quests 】
Ditch the deceptive "pages read" percentage. Our cross-media "Insight Timeline" tracks your true comprehension by recording the moments you actually extract knowledge. Encounter a tough concept? The system triggers an interactive Feynman Quest, prompting you to explain the idea in your own words before marking the node as "Mastered."
Stop being a hoarder of PDFs. Become an architect of knowledge. Download Thread Reader today and build your second brain.
