My kid goes to an English-only school in the US, but we speak Chinese at home. So I built her a tiny Animal Crossing-style island to learn English 🏝️ Snap a pic of the teacher's daily schedule → AI turns it into a lesson pack → she learns words from animal villagers, shakes apple trees, goes fishing 🎣 100% hand-written Three.js, zero assets, no backend.

Show HN: Fenzo AI – Interactive Micro-courses on any topic

An AI-powered platform for solving and collaborating on math problems in a social context.
lemma1729 · HN
Hi HN, This is ProofTree, and in TLDR: it is a platform where you can chat with an AI to do math, the way you already do, with context-awareness and knows how you personally do math, connected to the fora of other live human mathematicians. So, when you are talking to an AI about a proof at 3 am, and you need a human expert looking at it, or a discussion around it, like you do on StackExchange, this is it! You need an approved email account to use it, so please write here if you would live to try it out.

Chat with an AI assistant and earn money based on message quality scores.
u/as-333 · Reddit
Built an AI chat that pays you per message, scored in real time: looking for feedback I've been using Claude Code to build Argutum, an AI assistant that scores every message you send (0–100, five dimensions: complexity, novelty, structure, domain expertise, conversational depth) and pays you for the good ones. The underlying idea is that your prompts get sold as training data to AI labs, so you should get a cut instead of it happening for free. Stack: Next.js 16, Groq/Llama 3.3 70B, custom
