This n8n workflow automates the process of summarizing Slack messages triggered by a slash command. When a user types the /summarize command in Slack, the workflow fetches recent messages from the channel, prepares a concise prompt, and uses AI-powered summarization to generate a clear overview. The summarized content is then formatted into Slack blocks and posted back as an ephemeral message to the user, providing quick insights without cluttering the channel. This workflow is ideal for teams seeking to efficiently digest lengthy conversations or maintain focus during meetings.
