In the maker’s words, at launch

Hey HN, I’m Lee. I’ve always felt that most learning apps miss the point. They push you to memorize facts, but they don’t really help you understand things from the ground up. I built StudyBlocks as a way to counteract this by breaking down your topic of interest into first-principles. How it works: 1. Pick a topic…

  Hey HN! I’m excited to show you my app that lets you learn any topic in a structured, bite-sized way. Each lesson has an audio version, some visuals, and interactive quizzes. They’re personalized to your background and goals, and you can pick a concept inside a lesson and ask it to go deeper. When my co-founder was at NotebookLM, he realized the biggest bottlenecks in learning are that people don’t have time or feel like they’re not smart enough. We wanted to see if software can take the mental load of figuring out what resources to use and what order to learn them in, and make lessons easy…

  I’m building Decks, an application where you create study decks that consists of notes, flashcards, YouTube videos, and ChatGPT conversations. Notes and flashcards can be attached to YouTube videos. And your ChatGPT conversations are searchable and organizable through tags and folders. The concept is that this is study application where you can keep all your materials related to a subject in one place. Would appreciate any feedback you might have. Thanks!

  Built this because kids 10-15 can't prompt AI effectively. They'd type "make quiz plz" and get confused when ChatGPT asks for context. Lexie takes 46 steps of AI prompting, context explanation, and output formatting and makes it one step: point camera, get quiz. The photo constraint isn't just better UX, it's the only way to get usable output from that age group. This demographic gets the worst deal in edtech. Too advanced for baby apps, too young for adult tools. They get gamification theater instead of real learning tools. I stripped all that out. Photo your geology notes, get instant…

  I built an app to organize fragmented learning2025 · apps.apple.com · ▲5

  Hi HN, I built an app to solve a problem I kept running into: I’d read great articles or watch insightful YouTube videos, but within a few days, I’d forget most of what I learned. Taking detailed notes felt like a chore, and I'd rarely revisit them anyway. To solve my own problem, I built Curio. It's an iOS app designed for low-effort capture and active recall. How it works: 1. Share any article or YouTube link to the app. 2. It automatically extracts key ideas as bullet points and links them back to the original context (the specific paragraph or timestamp). 3. The app then generates…

  Strange Attractors▲804

  I went down the rabbit hole on a side project and ended up building this: Strange Attractors(https://blog.shashanktomar.com/posts/strange-attractors). It’s built with three.js. Working on it reminded me of the little "maths for fun" exercises I used to do while learning programming in early days. Just trying things out, getting fascinated and geeky, and being surprised by the results. I spent way too much time on this, but it was extreme fun. My favorite part: someone pointed me to the Simone Attractor on Threads. It is a 2D attractor and I asked GPT to extrapolate it to…

  Autism Simulator▲779

  Hey all, I built this. It’s not trying to capture every autistic experience (that’d be impossible). It’s based on my own lived experience as well as that of friends on the spectrum. I'm trying to give people a feel for what masking, decision fatigue, and burnout can look like day-to-day. That’s hard to explain in words, but easier to show through choices and stats. I'm not trying to "define autism". I’ve gotten good feedback here about resilience, meds, and difficulty tuning. I’ll keep tweaking it. If even a few people walk away thinking, "ah, maybe that’s why my coworker struggles in those…
