Hey HN, I'm Sándor. I built Wordy because I kept pausing Netflix to look up words in a dictionary. So I made a subtitle tool for myself, and it kind of snowballed from there.

What it does: You watch short clips from real movies and TV shows, then get quizzed on the vocabulary you just heard. The app tracks every word automatically and adapts to your level. 20+ languages.

How it evolved: Started as an iOS app for interactive streaming subtitles. Then I added curated video clips with quizzes. Then vocabulary tracking, spaced repetition, and personalized learning paths. Now it's iOS + Android + a Chrome extension (dual subtitles for Netflix and YouTube).

The whole thing is a solo project. Along the way it won a $30K prize at Hungary's biggest startup competition, which gave me the push to go full-time on it.

Stack: Swift (iOS), Kotlin (Android), Chrome extension.

Would love to hear what you think, especially from anyone who's tried learning a language from media before. What worked? What didn't?

Hey HN, I'm Long. I started building CodeLayers in November — a 3D code visualization app that started on Apple Vision Pro and is now on iPhone and iPad.

Why I built this: AI agents are writing more code than ever, and I realized I had no idea what my codebase actually looked like anymore. I wanted a way to see the architecture at a glance — what depends on what, where changes ripple, where the complexity is hiding. And I wanted it on my phone, not buried in some CI dashboard.

But getting the visualization right was harder than I expected.

Force-directed graphs were the obvious first attempt. They look cool for 20 files. At 500+ it's an unreadable hairball — positions are random and it looks different every reload. No meaning to where anything sits.

City view was next — files as buildings, metrics as height. Impressive in screenshots but useless for understanding how code actually connects. You see size, not relationships.

BFS from foundations is what finally clicked. I run BFS upward from depth-0 files (files that import nothing — your utils, types, constants). Each file's depth is the longest path from any foundation. Cycles get collapsed via Kosaraju's SCC detection. The result: layers emerge naturally. Position has meaning. Bottom = bedrock everyone depends on. Top = entry points. You're looking at real architecture, not a physics simulation.

And it tells you something useful: depth predicts blast radius. A change at depth 0 can ripple through hundreds of files. A change at depth 5 probably touches nothing else.

Two features I'm most excited about:

Remote AI agents from your phone. You can point Claude, Gemini, or Codex at your repo and ask questions about your code while looking at the 3D graph. Waiting for a build? Pull out your phone, ask the agent "what calls this function?" and see it highlighted spatially. Dead time becomes time understanding your codebase.

Watching your graph grow. The CLI syncs in real-time as you code. Watch your architecture evolve — see when a new dependency adds a layer, catch when a refactor creates a cycle, notice when a file is becoming a god object that everything imports. In a world where AI agents are making PRs, being able to see the effect of changes on your codebase at a glance is the thing I care about most.

Privacy was a hard requirement — all source code is encrypted on-device with zero-knowledge encryption before it leaves your phone. I can't read your code.

Free to explore public repos. Pro unlocks working with your own repositories — private repo support, CLI watch mode, git time travel, and AI agents.

Built this solo in about 3 months. Would love feedback — especially on what you'd want from a tool like this.

With AI infesting and eating into all kind of crafts--and I being one of those faceless "craftsmen"--I'm rather forced to consider alternative jobs. Setting the monetary rewards aside, I was thinking of jobs that could give me a sense of agency, purpose, and satisfaction (however limited). The few I think of are:

- Parcels delivery driver

- Train driver

- Electrician or plumber

- Mechanic (with auto-mobiles hardly repairable these days, maybe this doesn't qualify)

Surely, I can't be alone in thinking along those lines. What else have you thought of?

Outside of San Francisco, New York City, Boston, and Seattle, what U.S. cities have the most legitimate startup communities right now?

I'm curious what else is out there that we don't hear a lot about.
