Hi HN, As a developer, I much prefer to write code than read other people’s code. But most projects I work on involve other developers so it’s hard to avoid. Often I find it really hard to quickly parse other people’s code so I thought maybe ChatGPT could help. ChatGPT does a really nice job of giving clear explanations when you paste in code and ask it to explain it. But the interface is a bit of a pain to use if you’re using it many times a day. It’s also hard to share explanations with co-workers. So I built whatdoesthiscodedo.com. Just paste your code and get your ChatGPT explanation and…

Strive▲118Gemini's inbuilt canvas could compile Latex and create a pdf. ChatGPT can now as well, with the launch of their Apps SDK. We made an app that compiles the Latex code written by ChatGPT and shows the PDF in the chat window. Users can then ask ChatGPT to make further edits, or download the PDF and share it. It's most commonly used by math teachers to make math worksheets I would love to see what other apps the community has made and submitted to OpenAI for approval!

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...)
