SpatialRead

This is SpatialRead, a nonlinear research paper reading tool that is truly yours.

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. I'd get a great explanation from an AI, but it would just get lost in the chat history. I was still stuck copy-pasting insights into a separate app. Not to mention the subscription lock-ins.

I built SpatialRead to fix this. It's built on a simple idea: Your research tool should work like your brain, not like a chatbot.

SpatialRead combines a PDF reader with an infinite spatial canvas, all supercharged by AI. Instead of just "chatting," you can highlight any piece of text (from your original PDF or from a previous AI-generated answer) 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.

SpatialRead has genuinely changed the way I research, turning it from a passive act into an active, creative one. And if you ever felt trapped by subscriptions or platform lock-ins, you'll love SpatialRead.
