Use threads to organise discussions

Threads help you to create organised discussions around specific messages. They let you discuss a topic in more detail without adding clutter to a channel or direct message (DM) conversation.

Tip: With Slack AI, you can summarise threads in seconds to help you get up to speed more quickly. Learn more about Slack AI.
