Focused Discussions

The Discussion Interface

Focused Discussions

Threads, Not Channels

Cardinal gives your team discussions in focused threads. No more figuring out who was responding to what or trying to find a set of messages interleaved within broader discussions.

Asynchronous By Default

There are no dots telling you someone else is typing in Cardinal. We purposefully don’t design around the fear of missing out to control your team’s behavior. Discuss when you need to, focus elsewhere otherwise.
