AI-powered LinkedIn content engine (n8n + OpenAI + Perplexity + Replicate)

A fully automated content engine that researches, writes, scores, and visualizes LinkedIn posts — built with n8n, OpenAI, Perplexity, and Replicate.

What it does: ✅ Researches any topic using real-time data ✅ Writes a personalized post in your voice ✅ Refines tone and structure ✅ Generates abstract, high-quality visual assets ✅ Scores the output and saves it to Google Sheets

How it works:

• Triggered when you change a row status in Google Sheets
• Uses Perplexity to research
• GPT-4o (OpenAI) to create and polish content
• Replicate (FLUX Pro) to generate images
• Scores the post using heuristics
• Appends everything back to your sheet
