Product preview

Overview

Doubao is ByteDance's consumer AI assistant and one of the most-used chat apps in China. It is completely free, mobile-first, and unusually strong at voice: real-time conversations feel closer to a phone call than a chatbot session. Image generation, study help and a large library of specialized bots round out the experience.

Backed by ByteDance's recommendation and speech technology, it is tightly integrated with the company's ecosystem, which makes it the default AI companion for hundreds of millions of Chinese users — though its availability outside China is limited.
