The main chat tool used within Alibaba is DingTalk.

The reason is that DingTalk is a communication tool specifically designed for enterprise services, with multiple functions such as group chat, file transfer, video conferencing, etc., which can meet the needs of internal communication and collaboration within the enterprise.

At the same time, as an independently developed product of the Alibaba Group, DingTalk is interconnected with Alibaba's other business systems and has high security.

In addition, Alibaba also uses other internally developed communication tools, such as Qidian and Fetion, but the frequency of use is not as high as DingTalk.

Extended content: With the in-depth development of enterprise digital transformation, the tools for internal collaboration and communication in enterprises are also constantly updated and changing.

In addition to DingTalk, there are also WeChat Enterprise Account, Enterprise WeChat, Slack and other cloud collaboration tools. Different enterprises can choose different tools according to their actual needs.
