Notion to Ghost Blog Automation with n8n, Gemini & GPT-5

Turn new Notion pages into published Ghost blog posts—automatically

This n8n workflow watches a Notion database for newly added pages, converts the page content into a long-form blog post using Google Gemini (with OpenAI fallback), and publishes the result to your Ghost site via the Ghost Admin API—no manual copy/paste required.

What this workflow does

• Monitors Notion: Polls a specified Notion database every minute for newly added pages.
• Extracts full page content: Fetches the complete Notion page block content, including nested blocks, for each new entry.
• Builds a blog prompt: Extracts and concatenates the page content into a single prompt suitable for blog generation.
• Generates a blog post with Gemini: Uses Google Gemini (PaLM) to write an 800–1200 word blog post, with OpenAI configured as a fallback model.
• Formats for Ghost: Parses the AI output to derive a title and converts the content into Ghost Lexical format.
• Publishes to Ghost: Creates a short-lived Ghost Admin API JWT and sends a POST request to create and publish the post in Ghost.

Use cases

• When marketing or founders draft articles in Notion, automatically publish them to Ghost as soon as they’re added.
• For SaaS operators who want consistent SEO blog output from structured internal docs—using Gemini/GPT for generation and Ghost for publishing.
• For automation engineers setting up a reliable Notion → AI writing → Ghost publishing pipeline in n8n.
