Automate RSS to social media pipeline with AI, Airtable & GetLate for multiple platforms

Overview

Automates your complete social media content pipeline: sources articles from Wallabag RSS, generates platform-specific posts with AI, creates contextual images, and publishes via GetLate API. Built with 63 nodes across two workflows to handle LinkedIn, Instagram, and Bluesky—with easy expansion to more platforms.

Ideal for: Content marketers, solo creators, agencies, and community managers maintaining a consistent multi-platform presence with minimal manual effort.

How It Works

Two-Workflow Architecture:

1. Content Aggregation Workflow
   • Monitors Wallabag RSS feeds for tagged articles (#to-share-linkedin, #to-share-instagram, etc.)
   • Extracts and converts content from HTML to Markdown
   • Stores structured data in Airtable with platform assignment
2. AI Generation & Publishing Workflow
   • Scheduled trigger queries Airtable for unpublished content
   • Routes to platform-specific sub-workflows (LinkedIn, Instagram, Bluesky)
   • LLM generates optimized post text and image prompts based on custom brand parameters
   • Optionally generates AI images and hosts them on Imgbb CDN
   • Publishes via GetLate API (immediate or draft mode)
   • Updates Airtable with publication status and metadata

Key Features:

• Tag-based content routing using Wallabag's native system
• Swappable AI providers (Groq, OpenAI, Anthropic)
• Platform-specific optimization (tone, length, hashtags, CTAs)
• Modular design—duplicate sub-workflows to add new platforms in ~30 minutes
• Centralized Airtable tracking with 17 data points per post

2. Configure n8n credentials (~10 min)
   • Add all API keys in n8n's credential manager
   • Detailed credential setup instructions in workflow sticky notes
3. Set up Airtable database (~10 min)
   • Create "RSS Feed - Content Store" base
   • Add 19 required fields (schema provided in workflow sticky notes)
   • Get Airtable base ID and API key
4. Customize brand prompts (~15 min)
