Summarize & Reply to Slack Messages with Claude AI Assistant

This n8n workflow, named Mello, is a sophisticated Claude AI assistant integrated with Slack. It listens for the /summarize slash command in any channel, fetches recent unread messages using Slack's channels:history API, and employs Anthropic's Claude model to generate contextual summaries and intelligent reply suggestions. These are delivered as ephemeral private messages to the user, complete with interactive buttons for instant responses, ensuring privacy and efficiency.

Key benefits include drastically reducing Slack overload by condensing conversations into actionable insights, saving hours weekly for busy professionals, founders, and teams. It minimizes context-switching, prevents missing important updates, and streamlines communication without public noise. The workflow handles multiple channels seamlessly and supports easy customization, such as switching to OpenAI.

Ideal use cases: High-volume Slack workspaces in startups, remote teams, or agencies where message volume hinders productivity. Perfect for sales, support, or dev teams needing quick catch-ups. Setup takes ~10 minutes: create a Slack app with required scopes, add Claude API key, import to n8n, and test via slash command.
