24 alternatives to Explainpaper – Explain jargon in academic papers with GPT-3

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!

Explainpaper is a tool that helps readers understand academic papers by allowing them to upload a PDF and highlight confusing passages, formulas, or sentences for AI-powered explanations.

    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…

    Hi HN! I made a tool that autogenerates simple, high-level explanations of concepts and organizes them in a somewhat university course-like structure so that it's easier to see how things are structured. Currently it has about 20,000 concepts on a range of topics but that's just what I generated so far, it should work with more obscure topics in the future. I love learning about random topics where I don't have a good background in like history or linguistics, but it's hard to figure out what topics there (you don't know what you don't know) are in certain fields and what they are even…

    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...)

    I'm not a researcher. I'm just someone who gets unreasonably excited when a new paper drops in a field I have no business reading about. Protein folding? Fascinating. Quantum error correction? Sign me up. The problem is, jumping into a paper on topological qubits when your physics education stopped at "electrons go around the nucleus" is... humbling. So I built PaperSplain for myself. It implements the Three-Pass Method – an actual academic reading technique where you read a paper three times at increasing depth. First pass: what's the paper about and why should I care? Second pass: what did…

    Hi HN, I'm Ben, a solo developer. I've just launched ELI5 GPT: https://explaintome.netlify.app, a simple tool that utilizes GPT to explain anything in very simple terms — as if you're 5 years old. I built it because I was tired of having to Google explanations for tech topics that were either too complex or filled with jargon. I wanted something minimal, fast, and fun — no logins, no bloat. It's built with plain HTML, CSS, and JavaScript, hosted on Netlify. You can enter any concept (e.g., "quantum physics" or "inflation") and it'll explain it at a childlike level using AI. It’s…
