⚙ AI-Powered Social Media Automation for LinkedIn

---

How It Works

This workflow automates the entire social media content creation and publishing process for LinkedIn. It starts with a simple form to collect a topic or idea. The workflow then uses two AI agents to automatically generate both the written content and a unique image prompt. The AI-generated image is created, uploaded, and then downloaded before the final step, where both the content and the image are posted to your LinkedIn account.
