On March 3, 2026, QuestMobile released the "2025 Core Report on the Development of AI Application Layer." The report shows that due to China's well-established digital infrastructure and full-chain cost advantages, the Chinese AI application market achieved a leap in growth in 2025. By December 2025, the total monthly active user base of domestic AI applications had exceeded 1.4 billion.

In specific scenarios, mobile AI applications demonstrated strong penetration, with a monthly active user base of 722 million, accounting for 56.6% of the market share. At the same time, native AI assistants from smartphone manufacturers and PC-based AI applications recorded 559 million and 205 million monthly active users, respectively. The data indicates that domestic startups and big companies, through continuous technological iterations, have driven generative AI to spread from cloud-based large models to edge applications, achieving ecological construction from quantitative to qualitative changes.

From an overall trend perspective, AI assistants deeply integrated with hardware and standalone apps are jointly driving the formation of user habits. This large-scale user access not only confirms the practical value of AI in productivity and lifestyle scenarios but also signals that the application layer of large models has entered the deep waters of commercialization and popularization.
