Submit the form with your video topic, audience, length, and tone. Two sequential GPT-4o-mini agents run in order \u2014 the first writes a structured full-length video script with hook, three content sections, conclusion, and CTA; the second generates the complete SEO metadata package: an optimized title, three alternative titles at different angles, a full YouTube description with hashtags, 15 tags, and timestamped chapters. Everything arrives in one Gmail email, ready to record and upload. No video generation, no Fal.run, no Upload-Post \u2014 just OpenAI and Gmail.\n\n## How it works\n- **1. Form \u2014 YouTube Content Request** collects video topic, target audience, video length, tone of voice, and your name\n- **2. Set \u2014 Config Values** stores your recipient email, sender name, and channel niche \u2014 plus all form values\n- **3. AI Agent \u2014 Write Video Script** uses GPT-4o-mini at temperature 0.7 to write the full script: Hook, Introduction, three named sections with examples and tips, Conclusion, and Call to Action\n- **5. Set \u2014 Save Script and Config** saves the script output and re-carries all config values to the next agent\n- **6. AI Agent \u2014 Generate SEO Package** uses GPT-4o-mini at temperature 0.3 to generate: main title, 3 alternative titles, full description, 15 tags, and chapters with timestamps\n- **9. Code \u2014 Build Email** reads the SEO output and script, formats them into one structured plain text email with labeled sections\n- **10. Gmail \u2014 Send Content Package** delivers the complete package to your inbox\n\n## Set up steps\n1. In **2. Set \u2014 Config Values** \u2014 replace PASTE_YOUR_EMAIL_HERE, PASTE_YOUR_NAME_HERE, and PASTE_YOUR_CHANNEL_NICHE_HERE\n2. In **4. OpenAI \u2014 Script Model GPT-4o-mini** \u2014 connect your OpenAI credential\n3. In **7. OpenAI \u2014 SEO Model GPT-4o-mini** \u2014 connect your OpenAI credential\n4. In **10.
