We currently use x.ai with a small number of users, myself included. I am the one who purchased it initially as an individual user, and then eventually bought a team plan for my direct reports (4 in total) for internal and external meetings. The primary reason I initially bought it was to save time on scheduling meetings and to streamline that workflow so that I didn't have to manage my calendar as much. I now use it for that purpose and as a way to let others selectively see my calendar availability and schedule meeting with me. Our organization doesn't use x.ai broadly; it's limited to just my team.
