heyo! Explainpaper lets you upload a research paper PDF. If you don't understand a formula or sentence, just highlight it and the tool explains it for you I built this a few weeks ago to help me read a neuroscience paper, and it works pretty well! I didn't fine-tune GPT-3, but I do take a lot of context from the paper and feed that into the prompt (not the whole paper). Ppl have uploaded AI, biology, economics, philosophy papers and even law documents. Works in Chinese, Japanese, Spanish, French and more as well!

Hello fellow hackers, we made a site that gets GPT to answer your question using the info on a webpage you specify or document you upload (e.g., a large textbook .pdf file). Background: When ChatGPT came out, I had the idea of having it pull answers from my stereo receiver's annoyingly dense 32 page manual. My weekend project prototype proceeded to surprise with great answers—just like what we've all experienced by now. My co-founder thought we should productize it, and make it easy to use online. So here we are with a very early beta! (Try it on a HN thread...)

Hey HN! I built SimplePDF Copilot: an AI assistant that can interact with the PDF editor. It fills fields, answers questions, focuses on a specific field, adds fields, deletes pages, and so on. It's built on top of SimplePDF that I started 7 years ago, pioneering privacy-respecting client-side pdf editing, now used monthly by 200k+ people. As for the privacy model: the PDF itself never leaves the browser. Parsing, rendering, and field detection all run client-side. The text the model needs (and your messages) goes to whatever LLM you point at. By default that's our demo proxy (DeepSeek V4…

Hey HN, I built a PDF reader that can generate interactive visualizations right inside the document. The goal is to reduce the “intuition gap” when reading dense papers: select a concept, click Visualize, and it tries to produce a solid visual interactive app where you can rotate/zoom/step through (not just a text explanation). Upload any PDF, select text, click Visualize. Demo (no signup): https://zerodistract.com/try/pdf/67cdee74-810b-4f1b-af7d-010... Product link: https://zerodistract.com I’d love feedback, especially on what feels useful vs.…
