viviTalk – Learn Languages

Welcome to viviTalk — an AI-powered speaking practice app designed to help you overcome the 'silent learner' gap. It supports Chinese, Japanese, English, and Korean and uses AI-driven, story-based courses and map-based scenarios to make practice realistic and engaging. Your responses shape the story, and the learning loop goes input -> practice -> correction -> review, whether you're prepping for travel, business, or everyday conversation.

Key capabilities include role-playing with AI, vocabulary learning by images, and practical daily expressions. It provides real-time evaluation and grammar correction with explanations, detailed learning reports, and helpful learning supports such as translation, voice replay, hints, and native-language input. ViviTalk also prioritizes privacy with encrypted transmission and minimal data collection, and features a playful AI puppy companion to keep you motivated.
