Google Gemini generates an SEO-optimized product description with keywords\n3. A second AI call creates translations if needed (EN, JA, etc.)\n4. A Code node formats everything into a clean, ready-to-use structure\n5. Descriptions are saved to Google Sheets as your product copy database\n6. The final copy is emailed to you or your client via Gmail\n\n### Setup steps\n1. Connect Google Gemini API credentials (free tier works)\n2. Create a Google Sheet called \"Product Descriptions\" and connect it\n3. Connect Gmail for delivery emails\n4. Activate and share the form URL\n\n### Customization\n- Edit the AI prompt to match your brand voice or specific e-commerce platform (Shopify, Amazon, etc.)\n- Add or remove target languages in the translation node\n- Adjust the SEO keyword density instructions in the prompt"
