A: Loom is focused only on screencasts, and they have a wide range of features around them.

We do live screen sharing (as a way to turn a phone call into a meeting with a live presentation) as well as providing screencasts that you can record either while in a meeting with others, or without being in a meeting. You can also use your recordings and other videos you upload while in a screen sharing session, playing them at full quality to your viewer.
