So far I've used it to reference ideas from books I've read before. I've also used it to explore books I have not read before by asking the bot questions. Some people have told me they use it like a reading companion. They pause while reading the book if they have a question, and use Konjer to answer it.

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...)

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…

PDFToQuiz▲129As a former student I created PDFToQuiz to solve I problem I had in college, how could I be sure I knew and understood all the material in the notes if I couldn't test myself. That's why I built PDFToQuiz, it helps students test thier knowledge on their own notes.

Hi HN, I built https://rebrain.gg. It's a website which is intended to help you learn new things. I built it for two reasons: 1. To play around with different ways of interacting with a LLM. Instead of a standard chat conversation, the LLM returns question forms the user can directly interact with (and use to continue the conversation with the LLM). 2. Because I thought it would be cool to have a site dedicated to interactive educational content instead of purely consuming content (which I do too much). An example of a (useful-for-me) interactive conversation is:…
