OpenPaper – Understand Papers Using AI (Open-Source)

Hacker News

Hi 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 with an AI chat - Generate an audio overview from any paper - Find related papers (powered by OpenAlex) - Every AI response comes with grounded citations - Inline annotations - Compose your knowledge base with uploaded papers - Swap between GPT4 and Gemini2.5 Pro - Shareable annotations What are you looking for in a research assistant? Would love to get some thoughts / feedback on what I've built so far :). Thank you! Check out the GitHub --> https://github.com/sabaimran/openpaper
