Automated Social Media Content Publishing Factory + System Prompt Composition This workflow is a powerful automation for creating and publishing social media content. It uses AI to generate content and images based on external prompts and schemas, and routes the final posts to various social media platforms. How it Works This workflow operates as a "Content Publishing Factory". It generates platform-optimized content for platforms like LinkedIn, Instagram, Facebook, X (Twitter), Threads, and YouTube Shorts. A key feature is its dynamic system prompt and output schema composition, which pulls content from external Google Docs to ensure consistency. The workflow can also create images to match the content and send the final draft for approval via email before publishing. Use Cases Centralized Content Management**: Store and manage all system prompts and schemas in Google Docs for easy team collaboration and version control. Brand Consistency**: Ensure a consistent brand voice across all social media platforms by centralizing brand guidelines and content rules.
