Background & analysis
According to a Caixin report, Meta's launch of the personal agent Muse prompted Chinese tech giants to move quickly. On September 8 local time, Meta introduced Muse, a personal AI agent that can send emails and book travel on a user's behalf. With the user's explicit authorization, Muse can access data across email, calendar, payments, health, shopping and smart home apps.
Tencent launched its own personal agent, LightVela, in late September. Described as a cloud-based personal assistant, it connects through WeChat and stays online around the clock to handle everyday requests. The product is still in a developer preview stage.
On October 9, a ByteDance insider said the company had stepped up work on a personal agent product before the National Day holiday. The effort traces back to a new project started in April under the codename Spell, a continuation of ByteDance's 2025 work on personal agents for the Doubao mobile assistant, for which internal testing had already begun. After Muse and similar agents gained traction overseas, ByteDance accelerated the project. The product is led by the Doubao mobile assistant team, with the Spell project and the Doubao conversation team jointly responsible. The plan is to combine Spell with Doubao and release it to the public as soon as possible.
