Lark: Productivity Superapp for Chat, Meetings, Docs and Projects

Personally, I think it's economical and a wonderful service. However, people who have an antipathy to China don't seem to use this. I started using it because I could replace all of Notion, Zoom, Google Suite, etc. at work, but now I'm very satisfied.
