Automate Social Media Posts with AI & Slack Approval

Transform your social media content creation from hours of manual work into an automated, AI-powered system that generates on-brand posts across all platforms and routes them through Slack for seamless team approval. This n8n workflow combines Groq AI generation with intelligent approval workflows to streamline your entire social media operation.

What this workflow does

Operating on three flexible trigger modes, this automation delivers complete social media packages directly to your Slack workspace. Set it to run weekly on Monday mornings for batch content generation with detailed photo direction briefs, or let it automatically detect new Dropbox uploads and analyze images using Groq Vision to create matching captions. You can also trigger on-demand content generation via webhook with custom topics or context.

For each platform, you receive a comprehensive content package including captions, hashtags, suggested posting times, calls-to-action, and full photo direction covering subject, composition, lighting, mood, props, and elements to avoid. When images are uploaded via Dropbox, the workflow performs intelligent photo analysis to ensure captions match your actual content.

Approval workflow

Each generated post appears in Slack as an interactive Block Kit card with three action buttons. Approve instantly creates a Notion page and logs the post to Airtable, Retry flags content for regeneration, and Delete updates your tracking system. Error handling sends alert cards to keep your team informed of any issues.
