It monitors a Google Sheet for scheduled posts, uses AI to optimize captions and hashtags for specific platforms (Twitter and LinkedIn), and publishes them automatically. Finally, it updates the post status and notifies you via Slack.\n\n## Setup steps\n1. **Spreadsheet**: Create a Google Sheet with columns: `status`, `content`, `platforms`, `scheduled_time`, and `hashtags`.\n2. **Credentials**: Connect your Google Sheets, OpenAI, Twitter, LinkedIn, and Slack accounts.\n3. **Node Config**: Select your specific spreadsheet in both the 'Fetch' and 'Update' Google Sheets nodes.\n4. **Test**: Use the 'Manual Post Trigger' to verify the flow before enabling the 'Hourly' schedule."
