Doubao

Doubao is the chat assistant from ByteDance, the company behind TikTok, and one of the most widely used AI apps in China by a wide margin. It rarely appears in Western coverage, which gives a misleading picture of how many people actually use AI daily.

It is worth knowing about mainly for scale. Discussions about who is ahead in AI tend to compare labs and benchmarks while overlooking which assistants hundreds of millions of people genuinely open every day.
