What This Workflow Does
Managing social media across multiple platforms is a time-consuming juggling act. Between brainstorming content, creating images, writing captions, getting approvals, and hitting publish windows, marketing teams can spend 10+ hours weekly on repetitive tasks. This workflow automates the entire process—from AI-powered content generation to human-approved publishing—while maintaining brand safety and strategic oversight.
The system transforms a simple topic input into fully-formed, platform-optimized posts for LinkedIn, Twitter (X), and Instagram. It incorporates two-stage human approval (prompt review and final content review) to ensure quality control, then automatically publishes approved content through each platform's API. Everything is logged in Google Sheets for complete transparency and audit trails.
How It Works
1. Topic Input & Scheduling
A scheduled trigger checks your Google Sheet for new topics at your chosen frequency (daily, weekly, etc.). Each topic includes a brief description that guides the AI content generation.
2. AI-Prompt Generation & First Approval
AI generates tailored prompts for each target platform—professional tone for LinkedIn, concise hooks for Twitter, visual-focused concepts for Instagram. These prompts pause for human review before content creation begins.
3. Content & Image Creation
Once prompts are approved, AI writes full captions and generates platform-specific images using DALL·E or similar tools. Draft content is stored in Google Sheets with status indicators.
4. Final Content Approval
Complete posts pause for final human approval. Approvers can review text, images, and platform adaptations. Rejected posts are logged and skipped without publishing.
5. Multi-Platform Publishing
Approved content publishes automatically through LinkedIn, Twitter (X), and Instagram APIs simultaneously. Each platform receives optimized formatting—character limits, image dimensions, hashtag strategies.
6. Logging & Reporting
The workflow updates Google Sheets with publication timestamps, post URLs, approval history, and performance tracking fields for future analysis.
