SpatialRead
This is SpatialRead, a non-linear 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…

Open Paper2025 · openpaper.ai · ▲289Hi HN! Open Paper allows you to annotate and understand your research papers with an AI copilot. I wanted a paper-reading assistant that let met actually dig into papers in-place while benefiting from AI tooling. When it comes to studying, I'm not a fan of the typical chat interfaces that obfuscate uploaded files and turn them into black box 'content'. Hence, I've implemented a split-pane view. To mitigate the risk of hallucinations, all AI responses come with grounded citations that refer back to the source material in-flow. Some feature highlights: - Actually read your papers in one place…

Hey HN! I wanted to share something I built over the last few weeks: isometric.nyc is a massive isometric pixel art map of NYC, built with nano banana and coding agents. I didn't write a single line of code. Of course no-code doesn't mean no-engineering. This project took a lot more manual labor than I'd hoped! I wrote a deep dive on the workflow and some thoughts about the future of AI coding and creativity: http://cannoneyed.com/projects/isometric-nyc
