WeCom has officially begun beta testing its AI Agent “Dayuan.” Simply swipe left to activate it, with deep integration into workflows such as group chats, documents, and meetings. Even more noteworthy is its natural connection with WeChat — which means Tencent is embedding AI capabilities throughout the entire business operation chain for enterprise customers.

The “Big Circle” of WeChat Work Has Arrived — Private Domain Operations Are About to Change

WeChat’s AI Agent “Xiaowei” is still in beta testing, but WeChat Work has already caught up.

On June 23, according to multiple beta testers, WeChat Work officially launched its AI Agent codenamed “Big Circle” for internal testing. Unlike most AI tools on the market that require a separate app or entry point, “Big Circle” has a very clear product positioning: an AI assistant embedded directly into the WeChat Work workflow.

This positioning might sound ordinary, but if you understand WeChat Work’s role in China’s enterprise service market, you’ll know its significance. WeChat Work is not just an internal communication tool — it’s the largest B2C private domain operation gateway in China. Tens of millions of businesses use it to connect with WeChat users to do sales, customer service, and community operations.

Now, AI is coming in.

Swipe Left to Invoke — A Simple-Looking Interaction Design

Let’s start with the product form.

“Big Circle” is not a separate app or independent feature entry; it’s deeply embedded in WeChat Work’s daily operation flow. On mobile, the user only needs to swipe left on the screen to summon the AI assistant.

This design has a few notable points:

First, contextual awareness. The system can intelligently recognize the current interface and the user’s question. If you swipe left in a group chat, it knows you might want to ask what’s being discussed; if you swipe left while viewing a report, it knows you might need data analysis.

Second, multi-entry coverage. Messages, chats, documents, calendars — almost all frequently used interfaces can invoke “Big Circle.” This makes AI feel like a naturally embedded part of the workflow, rather than a separate tool to be opened.

Third, lowering the usage barrier. No need to learn new operations, no need to memorize specific commands — just swipe left. This is important for WeChat Work’s large number of non-technical users — salespeople, customer service agents, operators — they don’t need to know what Prompt Engineering is.

A few specific scenarios:

Too many group chat messages to read? Swipe left and ask “What’s being discussed in the group?” — automatic summary
Received a complex data report? Swipe left and let AI extract key conclusions
Preparing for a meeting but no time to review historical records? Swipe left and let AI recap relevant background

Sounds like an enterprise version of Copilot? Kind of — but Tencent has a unique advantage in doing this.

The Real Killer Feature: Connecting to Customer Management Scenarios in WeChat

What’s the biggest difference between WeChat Work and other collaboration tools?

It’s naturally connected to WeChat.

This means “Big Circle”’s ability boundaries go beyond internal collaboration — it can enter customer management scenarios. And this happens to be the pain point for many Chinese companies.

Pain Points of Private Domain Operations

The term “private domain traffic” has been overused in the past few years, but anyone who’s actually managed private domain knows the struggles:

Information overload. A salesperson may be dealing with dozens or hundreds of clients at once, with communication records piling up daily. What did the customer say last week, when did they express buying intent, what issues remain unresolved — all relying on human memory or manually searching chat logs.

Experience hard to replicate. Why do top salespeople perform so well? Largely because they remember customer details and say the right things at the right time. This skill is difficult to standardize and pass to newcomers.

Management black box. Managers wanting to know customer follow-up status must rely on employee reports. Real customer intent, actual progress, communication quality — either opaque or requiring heavy manual compilation.

The essence of these problems: WeChat Work contains vast amounts of customer communications, but this data is unstructured, fragmented, and hard to utilize.

AI’s Solution

In testing, “Big Circle” has already demonstrated features aimed at these pain points.

Service Summary Feature (in beta):

This feature can automatically extract key information during employee-customer interactions:

What the customer needs
How strong the purchase intent is
Where the current bottleneck lies

It then periodically pushes this to the employee, telling them which customers are worth prioritizing.

This is like giving each salesperson a tireless assistant who tracks all customer statuses and reminds them at the right time.

AI Smart Sheets:

Customer groups and information can be automatically deposited into an AI smart sheet, forming a unified management hub. This sheet doesn’t just store data — it can:

Automatically summarize follow-up status
Build data analysis dashboards
Break down customer intent distribution
Analyze conversion funnels
Evaluate service quality

In other words, things that used to require a data analyst or BI tool, AI now handles directly.

Automatic Customer Profile Generation:

This is a deeper capability. AI can understand and organize customer conversation data, converting scattered unstructured content into:

Reusable customer profiles
Follow-up summaries
Business insights

Previously, to understand a customer’s full situation you might need to read hundreds of chat messages. Now you can just ask “What’s this customer’s situation?” — and AI gives you the answer.

Who Will Be Most Affected?

If “Big Circle” succeeds, its biggest impact will be on several types of companies:

1. Retail & Consumer Brands Heavy on Private Domain Operations

These companies usually have many sales and customer service staff connecting with consumers via WeChat Work. A brand may have thousands of accounts, each with hundreds or thousands of chat logs behind them.

Previously these were dormant assets. Now AI can activate them, turning them into analyzable, actionable insights.

2. Education, Finance, Insurance — High-Ticket Industries

These industries have long customer decision cycles, require continued follow-up, and conversion heavily relies on the salesperson’s expertise and patience.

The service summary feature is highly valuable here — helping salespeople avoid missing any key info during complex follow-ups and take the right actions at the right time.

3. Companies Dependent on Agency/Distributor Systems

Many B2B companies reach end customers via agents, with WeChat Work as the key channel. But companies have little visibility into these interactions.

If “Big Circle”’s AI analysis can aggregate upward, companies can better understand real market conditions instead of relying solely on agents’ reports.

Tencent’s Advantage over Competitors

There are many enterprise AI assistants on the market — DingTalk has its AI, Feishu has theirs, plus independent AI customer service and AI sales tools.

What’s Tencent’s core advantage here?

Data Loop

Data in WeChat Work is native, complete, and real-time. AI doesn’t need to pull data via APIs or require integration — it’s situated where the data is generated.

This is key. Many AI tools are powerful but can’t get data in — or the data is incomplete and not live. WeChat Work has no such problem.

User Habits

WeChat Work users don’t need to learn a new tool. They already use it daily for communication, meetings, documents — AI simply appears as a natural enhancement.

This is easier than convincing users to adopt an all-new AI product.

Extension of the WeChat Ecosystem

WeChat Work connects to WeChat, meaning “Big Circle” can extend its capabilities to reach consumers. DingTalk and Feishu cannot — they are pure B-side tools with no direct consumer connection.

Issues to Watch

Of course, “Big Circle” is still in beta, and its final form and ability boundaries are not yet certain. Several issues are worth attention:

1. Data Security & Privacy

AI will read chat logs and analyze customer information, involving sensitive data. Companies will worry:

Will data be used to train models?
How is employee privacy protected?
How is customer information secured?

Tencent must provide clear answers in product design and compliance.

2. Accuracy of AI Capabilities

Summarizing group chats, extracting customer intent — these sound simple but heavily test AI’s comprehension. If summaries are inaccurate or intent misjudged, it could cause trouble.

User feedback during beta will be crucial.

3. Pricing & Commercialization

Will this feature be free for all WeChat Work users, or a paid add-on? If paid, what’s the pricing strategy?

WeChat Work’s basic features are free, but advanced ones (like conversation archiving) are paid. “Big Circle” will likely follow suit.

4. Coordination with WeChat AI

How will WeChat’s “Xiaowei” and WeChat Work’s “Big Circle” cooperate? Customers added to WeChat Work are essentially WeChat users — will AI capabilities be integrated?

This touches on Tencent’s overall AI product strategy, worth ongoing observation.

Bigger Picture: Tencent AI’s B-Side Deployment

Viewed in a larger context, “Big Circle” is an important step for Tencent’s AI capabilities landing in the B-side.

In early June, the official WeChat developer account released “Guidelines for Developers Integrating into the WeChat AI Ecosystem,” confirming WeChat AI entering public beta. Now WeChat Work follows suit, showing Tencent systematically injecting AI into its core product matrix.

For developers, this means opportunities:

WeChat Work’s API system may gain more AI-related capabilities
SaaS products based on the WeChat Work ecosystem can explore cooperation with “Big Circle”
The private domain operations tools track may undergo reshuffling

Summary

The beta launch of “Big Circle” marks AI Agents entering WeChat Work — China’s largest B2C private domain operation platform.

Its core value is not just having another chat-capable AI, but:

Deep embedding in workflows — not an independent tool but natural enhancement
Activating dormant data — converting unstructured chat logs into usable insights
Connecting B and C — an advantage unique to WeChat Work

For businesses heavily reliant on WeChat Work for private domain operations, this product is worth watching. For teams considering an enterprise AI assistant solution, “Big Circle” may shift selection criteria.

It’s still in beta — the final form may evolve. But the direction is clear: Tencent aims to make AI a native capability of WeChat Work, not an optional extra.

The battle has just begun.
