Blog post → social media drafts

When you publish a blog post, AI drafts LinkedIn and X posts for you to approve.

How it works

Trigger: RSS — new item in your blog feed

Detect the new blog post from your RSS feed.
Ask an AI model for one LinkedIn post and one X post in your tone.
Save both drafts to a Notion "Content queue" database for approval.

Code

JavaScript used in the Code step — already included in the template below.

Read drafts · Code node

// Mode: Run Once for Each Item
// The AI was asked for JSON like {"linkedin": "...", "x": "..."}.
const match = $json.text.match(/\{[\s\S]*\}/);
const posts = match ? JSON.parse(match[0]) : { linkedin: $json.text, x: "" };
const post = $("New blog post").item.json;

return {
  json: {
    title: post.title,
    link: post.link,
    linkedin: posts.linkedin,
    x: posts.x,
  },
};

Build it

Pick your tool — same automation, step by step.

Copy and paste straight into an n8n canvas (Ctrl+V), or download and use Import from File. Then connect your own credentials and replace every YOUR_… placeholder. AI steps use a Claude model node — swap it for OpenAI, Gemini or Ollama if you prefer.
