According to a Caixin report, Chinese tech giants moved quickly to follow Meta's September launch of the personal agent Muse, which can send emails and book travel for users, accesses data across email, calendar, payments, health, shopping and smart home only with user authorization, and lets users revoke access at any time; Mark Zuckerberg has described it as a key product on the path to "personal superintelligence." A ByteDance insider said the company stepped up work on its own personal agent project before China's National Day holiday: the effort began in April under the codename "Spell," extends its 2025 Doubao phone-assistant personal agent direction, and is led by the Doubao phone assistant team jointly with the Doubao conversation team, with plans to combine Spell with Doubao and launch it as soon as possible. Tencent, meanwhile, launched a personal agent product called LightVela in late September, positioning it as a "cloud personal assistant" that connects through WeChat and stays online around the clock to handle daily requests; it remains in a developer-experience stage.
