About Call Me Sensei

Call Me Sensei is a next-gen language learning app powered by AI companions and wrapped in a romantic anime-style mobile experience. Imagine learning Japanese through flirty RPG chats with emotionally intelligent characters. We're building a product at the intersection of AI, games, storytelling, and language edtech — and it's unlike anything on the market.
