Post blog articles to LinkedIn and Twitter with OpenAI captions and UploadToURL

Description

Turn your blog into a self-driving social media machine. This workflow monitors your RSS feed, extracts new content, and uses AI to craft platform-perfect posts for LinkedIn and Twitter/X, complete with hosted images.

🎯 What This Workflow Does

This workflow automates the transition from "published on blog" to "live on social" in three primary stages:

🔁 Step 1 — RSS Trigger & Filter

RSS Feed Trigger:** Polls your blog every 15 minutes to detect new articles
Validation:** Ensures each item has a title and cover image before proceeding

☁️ Step 2 — Media Hosting Bridge

Fetch Binary:** Downloads the blog’s cover image
UploadToURL:** Uploads the image to a public CDN and returns a stable URL for social platforms

🤖 Step 3 — AI Multi-Platform Posting

OpenAI Captions:** Generates:
LinkedIn → professional, long-form post
Twitter/X → short, punchy tweet with hashtags
Parallel Publishing:** Posts simultaneously to both platforms
Success Logging:** Tracks hosted image URLs and caption details

✨ Key Features

Built-in Deduplication:** RSS ensures no duplicate posts
Clean Data Processing:** Strips HTML for better AI output
Fallback Logic:** Uses default caption if AI fails
Reliable Media Hosting:** UploadToURL ensures public image access
