Tencent Opens WeChat API to AI Assistants on Huawei, Xiaomi and Other Phones
N.R. Finch
Tencent has opened WeChat's interface to voice assistants from Huawei, Xiaomi and three other phone makers, letting AI send messages and place calls inside WeChat — its first proactive move in the AI-phone gateway battle and a direct counter to ByteDance.
What exactly opened up — and what can phone assistants do inside WeChat?
Voice assistants such as Xiaomi's Xiao Ai and Huawei's Xiaoyi can now send messages, make voice calls and video calls inside WeChat via natural-language commands.
The rollout covers Huawei, Honor, Xiaomi, OPPO and vivo. WeChat says the partnership "is still advancing and features will roll out gradually."
This means → a user speaks one sentence to the phone, and the AI handles the WeChat task — no need to open the app, find the contact or type anything.
How does this differ from ByteDance's Doubao approach?
WeChat uses a structured-command model — the phone assistant sends standardised instructions to WeChat, WeChat executes them internally, and the assistant never sees the WeChat interface.
In plain terms = WeChat opened a "message window" only — the AI can pass a note in but cannot walk into the room and rummage around.
ByteDance's Doubao took the opposite path: its AI assistant could view the phone screen and simulate human taps — far broader access, which drew sharp pushback from Tencent, Alibaba and others.
This reflects two fundamentally different security philosophies: WeChat chose "I execute"; ByteDance chose "AI operates."
Why are financial features explicitly excluded?
WeChat explicitly bars voice assistants from accessing financial transactions, Moments and other sensitive functions.
ByteDance's Doubao likewise pulled back access to payments, finance and gaming after the backlash — both ended up in the same place.
This means → the entire industry is deeply cautious about "AI agents touching money" — AI-initiated payments and transfers remain off-limits for now.
Where does Tencent's AI-payment experiment stand?
A Tencent employee who tested the feature internally says the company is trialling AI payments inside WorkBuddy, its enterprise-office AI product.
The scope is extremely narrow: drawing funds from a dedicated WeChat wallet set up solely for AI transactions to buy virtual tokens within WorkBuddy.
In plain terms = this is not AI spending your money freely — it is an experiment inside a ring-fenced mini-vault, so any mishap cannot touch the main account.
What does all this mean for Tencent's share price and market expectations?
The Financial Times reported Monday that Tencent is testing an AI-agent prototype to help WeChat's 1.4 billion users navigate millions of mini-programs autonomously, with a possible launch as early as this month.
The news drove Tencent's stock up roughly 10% in a single day — its biggest one-day gain since late 2022 — though shares pulled back over the following days.
Year to date, Tencent's stock has fallen more than 20%, weighed down by concerns it is losing the AI race to Alibaba and ByteDance.
This means → the market gave Tencent a one-time "trust advance," but whether it holds depends on how fast and how deep AI features actually land.
