Slack
Bring team conversations and app updates together.
What is Slack?
Slack organizes team communication into channels and direct conversations, with integrations and lightweight audio or video collaboration. Its free and paid plans differ in message history, app access, and additional capabilities. It is useful when conversations need to stay connected to projects and operational signals, provided the team defines where decisions are recorded and which messages genuinely require an immediate response.
