Streamline the final stage of your content production workflow by automating publishing, formatting, metadata generation, and approval routing. This AI-powered subworkflow pulls optimized drafts from Google Sheets, enriches them with SEO metadata, converts them into publish-ready HTML, and delivers them via email and Slack for approval or distribution. Ideal for teams managing high-volume content pipelines with structured review processes. ✨📝🚀

  • Uses an AI agent (GPT-4) to generate SEO metadata, HTML-formatted article, tags, and structured publish data. 🤖
  • Enforces JSON structure to ensure consistent output formatting. 🧱

  • Sends the content to an approver via Gmail with a previewed HTML body. 📧
  • Awaits approval and branches based on decision. 🔀
