Super simple to use with refined usability. You collaborate across companies, sharing tasks, documents and chats — plus video calls and screen sharing without any local install. The only tool of its kind that's truly GDPR-compliant. Top service whenever questions come up. Review collected by and hosted on G2.com.

Tasks can only be assigned to rooms, so you need a little workaround — creating your own room to act as a personal to-do list. Not ideal. You also get updates from rooms you're not really involved in, which is mildly annoying but bearable. Review collected by and hosted on G2.com.
