Discord is an instant messenger that works on most devices, phones and computers. Discord is free and allows you to join different private groups on the same interface.
Within each group, lounges are organized by topic, allowing topics to be addressed in certain areas without crowding a single discussion space.
Originally used by gamers and streamers, it is becoming more and more popular during confinement.
The screen sharing and video conferencing features in the private discussion groups are very popular.
You can chat in voice or text chat rooms.
