Go to Workflow
Mariano Kostelec
Description
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
