Workflow name
Transform blog posts to multi-platform content with GPT-4o, Unsplash and Airtable

How it works

• RSS feed monitors your blog for new posts automatically • Extracts and cleans full article content from the blog post • AI Chain (GPT-4o) transforms content into 5 platform-optimized formats (LinkedIn, Twitter, Instagram, Email, Video) • Unsplash API suggests relevant images for each content piece • Slack notification alerts content team with preview of all formats • Airtable logs everything for content calendar tracking • Optional auto-posting to LinkedIn and Twitter (disabled by default) • Structured output parser ensures all 5 formats are generated correctly with proper character limits

Set up steps

Time to set up: 10-15 minutes • Replace RSS feed URL with your blog's feed (common formats: /feed, /rss, /feed.xml) • Get Slack channel ID for content team notifications • Create Airtable base with 14 columns (Original_Title, Original_URL, Published_Date, LinkedIn_Post, LinkedIn_Hashtags, Twitter_Thread, Twitter_Hashtags, Instagram_Caption, Instagram_Hashtags, Email_Subject, Email_Body, Video_Script, Suggested_Images, Status) • Add credentials: OpenAI (GPT-4o), Unsplash API, Slack OAuth2, Airtable Token • Replace placeholder IDs in Slack and Airtable nodes • Optional: Enable LinkedIn/Twitter auto-posting nodes and add OAuth2 credentials

What you'll need

OpenAI API - GPT-4o access for AI content repurposing • Unsplash API - Free tier available for image suggestions • Slack - Standard workspace for team notifications • Airtable - Free plan works for content tracking • Blog with RSS feed - WordPress, Ghost, Medium, Webflow all supported • LinkedIn/Twitter OAuth2 (optional) - For auto-posting feature

Who this is for

Content creators, marketing teams, and agencies that want to maximize content ROI by automatically repurposing blog posts into platform-specific content. Perfect for B2B companies publishing regular blog content who need consistent multi-platform presence without manual reformatting.
