How I Automated My Social Media with AI in n8n

Small habits are the backbone of every sustainable system.

In content creation, that means building processes you can repeat — without relying on bursts of inspiration.

Before I built this workflow, my publishing process was manual and inconsistent. I’d spend hours writing a single article or post, often abandoning drafts because the effort outweighed the output.

Now, my entire process — from idea capture to publishing across multiple channels — runs inside n8n.

The Bottleneck

Capturing ideas was easy. Turning them into consistent, high-quality content wasn’t.

• Rewriting the same concepts multiple times for different platforms
• Spending too much time editing
• Losing momentum between idea and publication

I needed a way to automate the structure of my content while keeping control over the final output.

The Build

Step 1: Capture the idea

I start with a voice note, transcribed using Voice Inc. This instantly converts spoken ideas into text I can feed into my workflow.

Step 2: Multiple AI article writers

The transcript goes to four AI “article writers” in parallel — Gemini 3, Gemini Flash, OpenAI GPT-4.1, and GPT-4.1 Mini. Each produces a draft based on a detailed system prompt that includes:

• My corporate identity (built using the Storybrand SB7 framework)
• Messaging structure from The One Page Marketing Plan
• A hook → problem → system → outcome format inspired by Matt Gray

Step 3: Selection and refinement

A Gemini “review agent” compares all four drafts, selects the best, and removes AI tell-tale phrases. This keeps the language natural and on-brand.

Step 4: Create a shareable document

The winning draft is sent to Google Docs via API, stored in a dedicated folder, and ready for manual image insertion.

Step 5: Platform-ready publishing

From there, I have options:

• Embed images in the doc
• Upload directly to Medium using a custom Python webhook
• Push to Substack, LinkedIn, or other channels via API

Why It Works

• Parallel generation finds the best draft without extra work
• Structured prompts ensure each version aligns with my brand and voice
• Human-in-the-loop review keeps the quality high and removes AI clichés
• Multi-channel output turns one input into articles, newsletters, and posts

The result is a Level 2 Automation that saves hours, maintains consistency, and keeps me publishing across multiple channels — without touching the blank page.
