"content": "## AI Inventory Assistant: Google Sheets & Gemini\n\nThis workflow creates a smart AI agent that uses a Google Sheet as its product catalog. It is the simplest way to build a \"Chat with your Data\" bot without needing complex databases.\n\n### How it works:\n\n1. **Chat Interface:** Users ask questions via the n8n Chat Trigger.\n2. **AI Logic:** The AI Agent node (Gemini) decides when to check the inventory.\n3. **Data Retrieval:** A Google Sheets tool pulls the entire list, allowing the AI to handle typos and find the best matches.\n4. **Memory:** A Simple Memory node enables natural follow-up questions (e.g., \"How much is it?\").\n\n### Setup Instructions:\n\n1. **Google Sheets:** Create a sheet with columns: SKU, Name, Price, Quantity and Category.\n2. **Credentials:** Set up your Google Sheets and Google Gemini (AI Studio) credentials in n8n.\n3. **Variables:** In the Google Sheets node, select your spreadsheet and the \"Inventory\" sheet/tab.\n4. **Prompt:** The template includes a pre-configured System Prompt. Adjust the personality to match your brand.\n\n\n**Ideal for:** Small product catalogs (<100 items), price lists, and internal inventory tracking.\n\nTo learn more about how to build and optimize this workflow, read the full blog post [here](https://n8nplaybook.com/post/2026/02/simple-n8n-inventory-ai-agent/).",
