OpenAI recently released an AI assistant called dots and Meta launched Muse. Both are designed to start as a personal helper and then reach out to other sites and services. In China, Tencent’s Xiaowei lives inside the WeChat super‑app. It can order items from merchants that already sell through WeChat or Alipay, but it cannot go beyond that closed ecosystem.
How the two models differ in practice
The open‑web agents let users link their own accounts and let the AI act on their behalf on external platforms. That freedom has already caused friction – Muse was blocked by Amazon, and both Muse and dots require users to hand over access to private data. Tencent’s Xiaowei avoids that step by staying inside WeChat, but it also means it can only help with services that are already part of the app. A Hello China Tech newsletter note says Tencent does not earn new fees from purchases made through Xiaowei and early tests show the bot sometimes makes mistakes.
Why it matters
For U.S. users, open‑web agents could let a single AI handle many online tasks, but they require sharing personal account data and may be blocked by services. Chinese users get a tighter, privacy‑friendly experience inside WeChat, but the assistant is limited to what the app already supports, which may reduce its usefulness.
