What it does
Erudity uses LLMs to turn any subject you can think of into a beautiful flashcard course in about 20 seconds. What wine tasters actually do. Why placebos work. What the Silk Road actually was. Pick a level, swipe through, tap any card for a Deep Dive long-read. For adults who keep 30 Wikipedia tabs open.

I used Claude Code to discover connections between 100 booksJan 2026 · trails.pieterma.es · ▲524I think LLMs are overused to summarise and underused to help us read deeper. I built a system for Claude Code to browse 100 non-fiction books and find interesting connections between them. I started out with a pipeline in stages, chaining together LLM calls to build up a context of the library. I was mainly getting back the insight that I was baking into the prompts, and the results weren't particularly surprising. On a whim, I gave CC access to my debug CLI tools and found that it wiped the floor with that approach. It gave actually interesting results and required very little orchestration…
- HLHow LLMs Work – Interactive visual guide based on Karpathy's lectureApr 2026 · ynarwal.github.io · ▲245
All content is based on Andrej Karpathy's "Intro to Large Language Models" lecture (youtube.com/watch?v=7xTGNNLPyMI). I downloaded the transcript and used Claude Code to generate the entire interactive site from it — single HTML file. I find it useful to revisit this content time to time.
Turn native language audio into flashcards and shadowing practiceJun 2026 · lingochunk.com · ▲92Here is a tool I built initially for myself to help with my German and Greek language studies. It started as a hack for creating Anki cards from native language audio. It extracts the words, finds their base forms (lemmas) and groups the examples by the lemma. At some point I realised that I have a transcription with word level timestamps that opens a lot of other opportunities. So I added a mode to click the first and last word in the transcript and it starts looping with the right gap and repeat count. Another feature I use a lot is selecting an audio fragment, sending a predefined prompt…
- FAFlashcard app to learn the vocabulary of English books/series/movies2019 · ▲7
Made this app because I was tired of not knowing 50 words/book when I read in English. You can try it on the AppStore searching "Quicky app". For Android user please use the web mobile version at https://quicky.app/. The Desktop version has a shitty responsive design. IMPORTANT NOTE: If you are not French, you will want to tell you are to try the features of the app (sorry it's only in French though) I'd love to hear your feedback.
- ULUsing LLMs to Research Reddit to Help Decide What to Buy2024 · claros.so · ▲16
Shopping online can be pretty tedious if you care about the quality of what you are buying. The time it takes can scale pretty proportionally to some combination of the value, relative importance, and complexity of the purchase. I think LLMs can help expedite and personalize the online shopping experience to a degree marketplaces just don't currently provide. I don't think anybody really wants to read the product descriptions of a bunch of products, read reviews, do pairwise product comparisons, and find the best deals across different websites? Or am I wrong? That's why I think this…

Hi HN! I was super frustrated at apps like tiktok and wechat preventing me from saving or downloading the animated gifs, so I made a little tool to turn a screen recording into a slack-sized emoji. Hope you get some value from this!
