Chatter is the collaboration layer built into Salesforce: feeds, posts, comments and groups that sit next to your records instead of in a separate chat tool. Think of it as a company bulletin board where every account, case and opportunity also gets its own board pinned to the record.
That matters because the conversation about a deal or a case stays on the record, where the next person who opens it can read it. Below we explain how Salesforce Chatter fits together, then walk through creating a Chatter group, adding Chatter to a Lightning record page, and posting to Chatter from a flow. Every screen comes from our Winter ’27 Developer Edition org.
