Seoulvivor: Speak Korean

A survival roleplay game for iOS that grades your spoken Korean. You talk out loud to AI-played Seoul locals — a taxi driver overcharging you, an immigration officer deciding your fate — and an AI examiner scores your listening, speaking and nunchi, TOPIK-style.

One-line boilerplate: Seoulvivor is an iOS game where an AI examiner grades your spoken Korean through survival roleplay missions set in Seoul.

The story

Seoulvivor is built by one person. Jamie Park designs, codes, and writes everything — the SwiftUI app, the real-time voice pipeline, the grading backend, and all 126 scenarios, each drawn from situations that actually happen in Seoul: the vendor who leaves a toothbrush on your lap and comes back for money, the landlord call you cannot rehearse, the immigration officer who needs a specific answer in a specific order.

The app exists because textbook Korean collapses the moment a taxi meter is running. Every language app teaches reading; almost none grade whether you can argue, apologize, or ask a favour out loud, in real time, from someone with no reason to be patient. Seoulvivor makes that the whole game.

What makes it distinctive

A passport, not a course

The entire app is styled as a Republic of Korea passport dossier — visa tiers, entry stamps, examiner report cards with real grades.

Voice-first, judged

There is no typing your way past it. You speak, a character answers back, and an AI examiner grades the exchange like a driving test.

Nunchi is a stat

Formality, timing, and knowing when not to argue are scored — the part a textbook leaves out.

A live city

New scenarios land every month, over the air, tied to the season — Chuseok, Hangul Day, year-end company dinners.
