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!

Hi HN, Just wanted to share a tool i've been working on to help with my own study routine. It’s a browser extension called Lingoku. The idea is simple: we spend hours browsing the web in English every day. This tool replaces some of the english words with Japanese vocabulary based on your japanese level (Similar to Toucan, but with a better user experience). It’s basically an attempt to make the "i+1" method actually passive, you understand the sentence because it's mostly english, but you pick up Japanese words naturally from the context. It uses an LLM in the backend to make sure the…

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…

Hey HN I read and research multiple things, both for work and personal curiosity. But I realized that in doing so, I have to frequently switch among many reading tabs and note-taking pages, which breaks my reading flow. That's why I teamed up with my friends to build Saner.ai Chrome Extension. It’s a side panel note that appears across tabs, and we can toggle it on and off whenever we like. Also, we can highlight any text and then use keyboard shortcuts to save it along with its URL. This has made my reading and research experience smoother :) I hope it will be helpful to people like us out…

"Explain This" was inspired by Github Copilot, where you can get an easy code explanation. So we bring this into a web app for customer support. I believe that chatbots are not it for customer support and that AI has better uses. "Explain This" allows the user to pick any part of web app and get it explained. The explanation is generated on the fly from the knowledge base; no need to have the content prepared; it will figure out the user's context and find the most fitting parts of the text we can then use to generate the content. When implemented it reduces the number of chatbot…
