Built a small tool to see how native speakers actually use words across different media (movies, podcasts, etc.) I used to use YouGlish a lot while studying, but it always felt pretty basic—you watch a clip, and that's it. I wanted a way to filter clips by specific media (movies, TV shows, podcasts), get translations, and actually ask an AI why someone used a word in that specific context when textbook definitions fell short. So I spent some time building my own version to

Launching our first iOS app was brutal… but it paid off🚀 Hey everyone 😊 We recently launched our first iPhone app, Learn Farsi iOS and man o man, what a ride it was! Some early numbers in the first 4 weeks: • 290+ downloads • 23 paid users, $700+ total revenue so far • Now at ~$100 MRR I know these numbers aren’t huge, but it honestly feels crazy to see people pay for something we built. It really shows that building for a small, underserved niche can work. A

My English was solid on paper, but I froze the second I had to actually speak. So I built a language partner that remembers you to practice with (24 languages). Hey everyone. I'm a senior CS student, kind of obsessed with AI/ML, and a solo dev. Bit of backstory: my English was always fine, but the moment I had to actually speak, I'd freeze and I didn't really have anyone to practice with. I tried a bunch of apps and they all felt like talking to a service bot polite, generic,

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. Try it:

Ten languages from English. Zero cost to try out, no trial period. One individual at work with software. Please test it out and DM me if you ar

Got tired of being so damn slow at writing, built an app to fix it I built this over a summer, which is a sentence I used to write about other things. I'm a physics student and a sailing instructor, I don't code, and I used an AI so I wouldn't have to learn — which, God help me, is the most honest thing I've said in this whole post. 31 sub-levels. It tracks the letters I get wrong and the specific pairs of letters I get wrong, which is more self-awareness than I've managed in a decade. Free
