🏡 Automated Real-Estate Content Generation Workflow
🏡 Automated Real-Estate Content Generation Workflow This n8n workflow automates turning short user ideas into production-ready real-estate marketing assets (photorealistic images and optional 360° videos). A form submission seeds a prompt board → an LLM refines prompts → the refined prompt is sent to an image/video generator → assets are uploaded to Google Drive and an approval email is sent so stakeholders can accept/reject outputs. ⚙️ How It Works (High Level) Trigger: User submits the ideation form (On form submission). Record: The raw idea is appended to Google Sheets (Append row in sheet). Refine: An AI agent (LangChain/OpenAI) refines the prompt into a photorealistic prompt and produces captions & variants (AI Agent). Store Refined Prompt: Update the sheet with the improved prompt (Append or update row in sheet). Generate Asset: Send improved prompt to OpenAI image/video generation nodes (Generate an image2 / Generate a video). Upload & Share: Upload resulting files to Google Drive (Upload file / Upload file1) and set sharing permissions (Share file / Share file1). Approval Flow: Email the requester with the asset + improved prompt and wait for approval (Send message and wait for response). Decision: A Switch node routes approved outputs to final storage/notifications and rejected ones back for rework (or sends a failure email). Video Branch: Separate flow → refine → HTTP → video generator → upload → share → update sheet (parallel video pipeline).

Rate Limits & Retries:** Add retry logic with exponential backoff for API calls. Wait Times:** Use Wait nodes for long video generation tasks. File Size & Format:** Standardize image sizes (e.g., 1792×1024) and compress videos. Sharing Permissions:** Use view-only links for approvals. Logging & Observability:** Track prompt, model, timestamp in Google Sheets. Security:** Use credential manager, rotate API keys regularly. Cost Control:** Monitor OpenAI usage and apply limits. Input Validation:** Validate prompt length and required fields. 🚀 Customization Ideas Property type presets (apartment, villa, office, etc.) Auto-generate captions, hashtags, and listing descriptions Add AI moderation before sharing assets Replace Google Drive with S3 / Cloudflare R2 + CDN Auto-post approved assets to social media or CMS A/B test prompts for performance optimization Multi-language prompt support Slack/Telegram approval dashboard instead of email 🏷️ Tags n8n, automation, real-estate, prompt-engineering, OpenAI, DALL·E, video, google-sheets, google-drive, gmail, approval-flow, image-generation.
