Both graphene documents and Daoyun collaboration were cloud collaboration tools, but they had different functions and features. <strong></strong> It provides a variety of editing modes, sharing methods, access control and other functions. It also provides a powerful code editor and table tools to make document editing and collaboration more efficient. The graphene document also provided cloud-based synchronization function, allowing documents between multiple users to be synchronized in real time. Daoyun collaboration was a cloud-based collaboration tool that allowed multiple users to collaborate and share documents on the same platform. It provides a variety of collaboration functions such as task management, schedule, file sharing, voice and video calls, etc. It also provides cloud-based synchronization function that allows real-time synchronization of files between multiple users. The Daoyun collaboration also provided some unique functions such as "Daodao Translator" and "Daodao Notes", which made the collaboration more intelligent and convenient. In general, both graphene documents and Daoyun collaboration were excellent cloud collaboration tools. The appropriate tools could be selected according to specific needs and scenarios.
