Show HN: Evidence-based agents for PDF chat, academic search, and paper editing

https://app.ubik.studio/chat
1•ieuanking•2h ago
Hey everyone!

Ubik is great for academic research workflows, like uploading/marking up PDFs and searching scholarly databases. We built agents that can create precise annotations (notes) down to the line level, and can be referenced later when prompting agents using the @ symbol (like Cursor). Through @ sign note-referencing in prompts, agents stay grounded in source material added to the context window, minimizing hallucinations while building contextual understanding of user needs through interactive note-taking and PDF viewing in-browser.

We graduated from college right before ChatGPT was released, and we worried about AI's effects on learning, reading, and original research. We've spent the last 2 years building a platform that integrates the best parts of being human, like reading, writing, and thinking, with evidence-based AI agents.

If you think this sounds helpful, try it out, and let me know if you think this is a good tool for higher education and professional research. We are a small team of 2. A complete local app and evals coming soon <3
