SpatialRead

SpatialRead is a node-based infinite canvas desktop app that let's you understand complex research papers quickly with the help of AI. You can highlight confusing portions of text and get simple AI explanations. In addition to highlighting text, you can get explanations for figures, diagrams, charts, and tables with the screenshot feature.

I tried all the "Chat with your 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.

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 powerful 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 powerful AI 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.
