LLM-based Toolset for Language Learning

I built an open-source tool for learning anything using AI: - Type what you want to learn - It creates a full interactive course for you Move from beginner to mastery of any subject, even complex things like Quantum Physics It has three formats: - Explanation: bite-sized lessons that you swipe like TikTok/Instagram - Practice: solve problems in real-world situations - Quiz: test your knowledge in Duolingo-like lessons - Language courses have a different format covering vocabulary, reading, and listening skills It's more hands-on than reading a long textbook or watching a video Plus, it…

An all-in-one blog for learning LLM ins and outs: tokenize, attention, PE, and more Project I've been diving deep into the internals of Large Language Models (LLMs) and started documenting my findings. My blog covers topics like: Tokenization techniques (e.g., BBPE) Attention mechanism (e.g. MHA, MQA, MLA) Positional encoding and extrapolation (e.g. RoPE, NTK-aware interpolation, YaRN) Architecture details of models like QWen, LLaMA Training methods including SFT and Reinforcement Learning If you're interested in the nuts and bolts of LLMs, feel free to check it out:…

Hi HN, I'm a solo developer learning to code, and I'd love to share my second real project: MapMyLearn, an AI-powered app that automatically generates personalized learning paths based on any topic you input. What it does: Takes a topic (e.g. "history of capitalism", "learn Rust", or "data storytelling") Uses AI to break it down into a structured course with modules and submodules Each submodule includes: - Detailed, pedagogical content (developed based on online sources to mitigate hallucinations) - A quiz of 10 questions - Recommended resources - An AI chatbot for Q&A - Optional audio…

Itsumo is a language learning app that generates short lessons from stories about topics you choose, at your level. Instead of working through a fixed curriculum or another flashcard deck, you can make a lesson about whatever happens to be interesting to you that day, with audio, tappable words, and grammar notes. You can try a language story from the landing page without signing up, and if you want to try full access, no credit card is required at signup, and the premium tier free for 14 days. It supports Japanese, Polish, Spanish, English, Portuguese, French and Italian. I built it because…

Hi all, I threw together a small prototype I am calling “Notepad.ai”. A new take on UIs for interacting with LLMs. While I enjoy using LLM’s in the chat format I wanted to see what it would be like to do it in a more long form style. It let’s you write in a pretty free form, much like Window’s Notepad, but you can choose to hit ctrl+[ to analyze the text with a preset prompt of your choosing. It has a few other small features. It’s WIP and very experimental. I would appreciate any feedback or thoughts. Video: https://youtu.be/ntdlgFmSxQY Live Demo:…

I’ve been building LLM tooling for a small VC fund and found myself explaining the same mental model over and over to non-technical people around me: how a stateless LLM becomes a chatbot, how tool use works, what an agent is mechanically, and why context windows shape all of it. I never found a guide that covered that full chain at the level I wanted, so I wrote one. It’s nine short chapters, each building on the last. Deliberately simplified: the goal is a useful mental model, not a textbook. Feedback, corrections, and contributions welcome: github.com/ymyke/aiaiai
