AI Summarize Slack Channel Activity for Weekly Reports (n8n)

Bring Your Slack Week Back Into Focus—Automatically

This n8n template automatically summarizes last week’s Slack channel activity and posts a ready-to-read weekly report back to your team—so important decisions and ideas don’t disappear by the weekend.

What this workflow does

• Runs on a schedule: a scheduled trigger starts every Monday at 6am.
• Collects Slack messages: it gathers all team channel messages from the previous week.
• Groups activity by user: message threads are grouped per user, and replies are mined to understand what happened within each thread.
• Uses AI to find highlights: an AI analysis pulls out interesting observations and key takeaways from the raw threads.
• Generates individual reports: each user’s summarized threads are combined and passed to another AI agent to create a higher-level “their week” overview.
• Creates a team weekly report: all individual reports are summarized together to form a single team-level weekly recap.
• Posts at the right time: the team weekly report is sent back to the channel as the first message of the week—ready for a quick glance over coffee.

Use cases

• Remote team weekly alignment: turn busy Slack history into a clear Monday recap.
• Project management visibility: help PMs spot progress, recurring themes, and key decisions across threads.
• Async teams keeping context: reduce the chance that “in-the-moment” information is lost.

Technical details

• Trigger: scheduled Monday run at 6am.
• Slack integration: retrieves channel messages and thread replies.
• Workflow logic and control: uses nodes including if, set, code, no op, slack, and filter.
