The app shell goes in easily: lessons, streaks, XP, paywall and an LLM roleplay tutor. The heavy part is the Korean curriculum itself, plus speech recognition with pronunciation feedback that has to feel right before learners pay. That's a lot of content and polish.

Why people pay Kori

Customers pay for a product that works, and a good copy can match it. Kori has no network, data or licence advantage built up yet.

Product complexity
High
Lessons, speech feedback, AI roleplay, streaks, XP and unlockables add up to months of work.
Data
Moderate
Needs a Korean curriculum of Hangul, phrases and romanization, plus speech recognition for feedback.
Integrations & infrastructure
Low
Paywalls run through Superwall; the rest is standard web app code and APIs.
Human operations
Low
Lessons are delivered by software, so no staff are needed to serve learners.
Regulation / hardware
Low
Teaching language lessons needs no licences or approvals.
