According to Quest Mobile's June 2026 data on monthly active users (MAUs) for standalone AI applications, Doubao, an AI-integrated assistant, stands out as the clear leader with 382 million MAUs. This figure is nearly 2.3 times the user base of Qianwen, which ranks second. DeepSeek, the sole AI search engine to crack the top three, secures the third position. Among the top four, integrated AI assistants hold three spots, while the fifth through tenth places are primarily occupied by vertical AI products, whose user bases are significantly smaller than those of general-purpose integrated AI assistants. Four integrated assistant products made the list, with a marked disparity between the top and bottom performers. Kimi, which specializes in long-form text reading scenarios, has fewer than 10 million MAUs. These statistics—(Note: The original term "Statistics" is retained here for contextual accuracy, though "statistics" would be the standard translation for data analysis purposes)—cover only independently downloaded apps and exclude AI assistants pre-installed by manufacturers. The data suggests that the domestic AI market landscape is largely established, with general-purpose integrated AI dominating the field, and Doubao is unlikely to be overtaken by competitors in the near future.
