One-sentence summary
Using QuestMobile's September 2026 data, this walks through four steps to read office-agent MAU: absolute scale and rank, QoQ growth and base, product ownership and scenario, then trend.
Step 1: Absolute Scale and Rank
Tencent WorkBuddy leads at 32.353M MAU, then Baidu Dazi 9.77M, Alibaba Qwen Office 7.905M, Tencent QClaw 3.173M, Doubao Work 2.049M. Establish the top tier first.
Step 2: QoQ Growth and Base
Baidu Dazi's +1567.5% QoQ is highest but off a small base; Tencent WorkBuddy +647.1%, QClaw +57.9%. Read high growth alongside its base to avoid being misled by small-base surges.
Step 3: Product Ownership and Scenario
Tencent's WorkBuddy and QClaw together are the largest; Doubao Work is a later entrant at fifth. Note the difference between general assistants and office-specific agents.
Step 4: Forward Trend
A single month reflects September only; watch later months to see whether retention and growth are sustainable.
