Fluency Simulator

About

Fluency Simulator turns language practice into realistic, spoken role-play. Pick your profession, choose a language, and hold a real conversation with an on-device AI that plays the other party — a patient, a client, a customer — while an animated avatar speaks back to you. Built for professionals whose careers depend on a second language: nurses, doctors, lawyers, real-estate agents, salespeople, managers, and more.
