SpatialRead is a nonlinear research paper reading tool. I tried all the "Chat with PDF" apps. They're useful, but I always felt...trapped. My research process isn't a single, linear chat log. It's a branching, messy, and visual process of connecting ideas.

SpatialRead combines a PDF reader with an infinite canvas, all supercharged by AI. Instead of just "chatting," you can highlight any piece of text and use actions like Simplify, Explain, or Expand. Each new insight is added to the canvas as a new, connected node. You can literally watch your knowledge graph grow as you dive deeper into a topic. With Bring Your Own Keys (BYOK) and a lifetime purchase, SpatialRead is truly yours.
