Jinjja — become genuinely fluent in Korean.

Most language apps turn a beautiful culture into flashcards. Jinjja (진짜 — "genuine, for real") teaches Korean the way native speakers actually think about it: through its music, its dramas, its streets, and its food. It's a calm, premium platform you'd recognize from a single screenshot.

The idea

Words stick when they mean something. Jinjja is built on two beliefs. First, learn through culture — K-pop lyrics, K-drama scenes, food, and Seoul neighborhoods, so every word arrives attached to something you actually care about. Second, learn through immersion — lifelike, interactive scenarios (order a coffee, ride the subway) so it feels less like a course and more like slowly moving to Korea.

What's built

The design is the difference

Jinjja is built to be impossible to mistake for a templated AI product. The whole identity hangs on one artifact — the Korean seal stamp (도장) — and one palette: the jade-green of celadon pottery on warm hanji paper, in charcoal ink, set in an editorial serif and stamped in vermilion. It looks like a considered object, not a dashboard.

Why it's here

I've volunteered and lived across the world, and spent real time drawn to Korea — this is that pull, turned into something I'd want to use every morning. It's also the same instinct as my AI work: care about the craft, and build the whole experience, not a demo.

Project facts
  • Status: in private development — feature areas above are built and running locally; a public beta is planned. Not live yet.
  • Built with Next.js (App Router) + TypeScript and Tailwind, with a bespoke design system rather than an off-the-shelf template.
  • A live syllable builder on the landing page, and a working Hangul lesson with a quiz and spaced-repetition reward.
  • The identity — celadon, hanji, the vermilion seal — is applied consistently across every screen.
