What This Workflow Does
This automation solves a critical challenge for modern content teams: producing visually consistent images at scale while maintaining brand identity. Manual image creation is time-consuming, expensive, and often results in inconsistent visuals across campaigns.
The workflow connects Google Sheets (where you manage prompts and references) with Google Gemini AI (which analyzes visual styles and generates new images) and Google Drive (where final assets are stored). It creates a complete pipeline from creative brief to finished asset without manual intervention.
When triggered, the system reads pending tasks from your spreadsheet, analyzes reference images to extract style characteristics, generates new images that match those styles, uploads them to Drive, and updates the spreadsheet with results—all while sending real-time notifications about progress.
How It Works
1. Task Management in Google Sheets
Your team maintains a Google Sheet with columns for image IDs, primary prompts, style prompts, reference image URLs, and status. This becomes your centralized content production dashboard where anyone can submit image requests.
2. Reference Image Analysis
For each pending task, the workflow downloads the reference image and sends it to Google Gemini for visual analysis. Gemini examines color palettes, composition, lighting, artistic style, and other visual characteristics that define your brand's look.
3. AI Image Generation
Using the style analysis from the reference image combined with your text prompts, Gemini generates new images that maintain visual consistency while applying your specific creative direction. The AI understands how to replicate styles rather than just copying images.
4. Asset Management & Notification
Generated images are automatically uploaded to designated Google Drive folders with proper naming conventions. The original spreadsheet is updated with download links and status, while team members receive notifications via ntfy.sh about completed tasks or any errors.
Who This Is For
This template is ideal for marketing teams producing social media graphics, e-commerce brands creating product visuals, content agencies managing multiple client campaigns, and any business needing consistent branded assets at scale.
If you're currently spending hours with designers or struggling with inconsistent visuals across platforms, this automation can transform your content production. It's particularly valuable for teams that already use Google Workspace and need to integrate AI image generation into their existing workflows.
What You'll Need
- Google Workspace account with access to Sheets and Drive
- Google Gemini API credentials (available through Google AI Studio)
- Self-hosted n8n instance (community nodes are used)
- Reference images that represent your desired visual style
- Organized Google Sheet with proper column structure for task management
Pro tip: Start with 3-5 high-quality reference images that perfectly represent your brand style. The AI learns better from clear, consistent examples than from dozens of mixed-quality references.
Quick Setup Guide
- Import the template into your n8n instance using the downloaded JSON file.
- Configure credentials for Google Sheets, Google Drive, and Google Gemini in n8n's credentials management.
- Update spreadsheet IDs in the Google Sheets nodes with your actual document and folder IDs.
- Customize notification settings by replacing the ntfy.sh topic with your unique channel.
- Test with sample data by adding a few rows to your Google Sheet with prompts and reference URLs.
- Activate the workflow and trigger it via webhook or schedule it to run automatically.
