How We Built an AI-Powered Blog Auto-Generation System

Every successful blog needs consistent content, but maintaining that consistency manually is exhausting. That's why we built an automated blog content generation system that creates draft posts on a schedule, leverages AI for content ideas, and integrates seamlessly with our development workflow.

The Problem: Content Consistency is Hard

Creating high-quality blog content is time-consuming:

• Ideas: Coming up with topics that resonate with your audience
• Research: Gathering information and structuring articles
• Writing: Crafting compelling, SEO-optimized content
• Editing: Reviewing, fact-checking, and polishing
• Publishing: Deploying and promoting content

We wanted to automate the heavy lifting while keeping human creativity at the core.

Our Solution: Automated Pipeline + AI Integration

We built a complete automation system that:

• ✅ Generates draft posts automatically using GitHub Actions
• ✅ Integrates with AI for content suggestions and structure
• ✅ Manages content queues via CSV files
• ✅ Creates preview deployments on Vercel automatically
• ✅ Enables draft mode for safe preview without public exposure
• ✅ Pair-appropriate

Architecture Overview

CSV Queue → GitHub Action → AI Processing → MDX Generation → PR → Vercel Preview → Review → Publish

Key Components

1. GitHub Actions Workflow

Our automation starts with a scheduled GitHub Actions workflow that runs every weekday:

name: Auto Draft Post

on:
  workflow_dispatch: # Manual trigger
  schedule:
    - cron: '0 6 * * 1-5' # Monday-Friday at 6 AM UTC

permissions:
  contents: write
  pull-requests: write

jobs:
  draft:
    runs-on: ubuntu-latest
    steps:
      - name: Generate draft post
        id: gen
        run: node scripts/generate-post.cjs
      
      - name: Create Pull Request
        uses: peter-evans/create-pull-request@v6
        with:
          branch: draft/${{ github.run_id }}
          title: "📝 Draft: ${{ steps.gen.outputs.slug }}"
          labels: draft

Why it's awesome:

• 📅 Runs automatically every weekday
• 🤖 Zero manual intervention required
• 🔄 Consistent content pipeline
• ✅ Creates PR for easy review

2. Draft Generation Script

Our script reads from a CSV queue and generates valid MDX files:

// scripts/generate-post.cjs
const fs = require('fs');
const path = require('path');

function main() {
  const now = new Date();
  const slug = slugify(`auto-draft-${timestamp}`);
  
  // Generate frontmatter with all required fields
  const frontmatter = {
    title: 'Auto Draft...',
    description: 'Auto-generated draft...',
    slug: slug,
    date: now.toISOString(),
    lang: 'en',
    tags: ['pipeline', 'draft'],
    draft: true,
    // ... all required fields
  };
  
  // Write MDX file
  fs.writeFileSync(path, mdxContent);
}

Smart features:

• 🎯 Generates unique slugs with timestamps
• 📝 Includes all required frontmatter fields
• 🔗 Outputs slug for PR description
• ✅ Creates valid Contentlayer-compatible MDX

3. Draft Mode System

We implemented Next.js Draft Mode to safely preview content:

// src/app/api/admin/enable-draft/route.ts
export async function GET(req: Request) {
  // Basic Auth validation
  const auth = req.headers.get('authorization');
  const [u, p] = Buffer.from(auth.split(' ')[1], 'base64')
    .toString().split(':');
  
  if (u !== user || p !== pass) {
    return unauthorized();
  }
  
  // Enable draft mode
  const draft = await draftMode();
  draft.enable();
  
  return NextResponse.json({ ok: true });
}

Why it matters:

• 🔒 Protected by Basic Auth
• 👁️ Preview content without publishing
• 🚀 No impact on production
• 🎯 Perfect for content review

4. Content Queue Management

Our CSV-based queue system:

title,description,lang,tags,author
"How We Built Our MVP in 6 Weeks","A detailed case study...","en","startup,mvp,case-study","Anna Hartung"
"Wie wir unser MVP gebaut haben","Ein detaillierter Fallstudienbericht...","de","startup,mvp,fallstudie","Anna Hartung"

The script automatically:

• Reads the first topic from the queue
• Removes it after processing
• Generates the draft post
• Falls back to sample content if queue is empty

Future enhancements:

• 📊 Notion integration for topic management
• 🤖 AI-powered topic generation
• 📅 Scheduling specific dates
• 👥 Multi-author support

5. Vercel Preview Integration

Every PR automatically creates a Vercel Preview:

• Instant feedback: See how content looks in production environment
• Draft mode support: Preview draft posts safely
• Team collaboration: Share preview links with stakeholders
• SEO preview: Check how content appears in search results
