What this automation does
Every time you publish a blog post, this automation reads the full article, extracts the key insights and quotable lines, and generates a set of social media posts tailored for each platform — a LinkedIn thought-leadership post, a Twitter thread, an Instagram caption, and a Facebook post.
Most content teams write a blog post and then struggle to repurpose it consistently. This automation turns one piece of content into 5-8 social posts automatically, keeping your channels active without extra effort. The AI adapts tone, length, and format for each platform.
Tools you need
- WordPress or CMS with RSS: Your blog platform — triggers the automation on new posts
- OpenAI API: GPT-4 reads the blog and generates platform-specific posts ($0.05-0.10 per blog post)
- Zapier or Make: Connects your blog to OpenAI and schedules posts via Buffer or Hootsuite
How to set it up
Step 1: Create a Zapier zap triggered by new items in your blog's RSS feed (or a new post webhook from your CMS). Extract the full post content, title, and URL.
Step 2: Send the blog content to OpenAI with a prompt that asks for: one LinkedIn post (200-300 words, professional tone, ends with a question), one Twitter thread (5-7 tweets, punchy and opinionated), one Instagram caption (casual tone, includes emoji suggestions and hashtags), and one Facebook post (conversational, includes a discussion prompt).
Step 3: Route each output to your social media scheduling tool. Use Buffer, Hootsuite, or Zapier's native social integrations to schedule posts across the next 5-7 days so you get sustained engagement from a single blog post.
Step 4: Review the first batch of generated posts. Adjust the prompt to match your brand voice — specify words to avoid, tone preferences, and whether you want first-person or third-person perspective.

Frequently asked questions
Not if you include brand voice examples in your prompt. Provide 3-5 examples of posts you have written that performed well, and tell the AI to match that style. After one round of tweaks, the output is usually indistinguishable from hand-written content.
This recipe focuses on text content. You can extend it by adding a DALL-E or Midjourney step to generate images, or use Canva's API to create carousel templates. That adds about $10-20/mo and 15 minutes of extra setup.
