"content": "# Overview\n\nThis **n8n** workflow listens for incoming chat messages, uses **Google Gemini (PaLM)** via **LangChain** to process or reply, optionally reads a **Google Docs** file if mentioned, and logs both the user input and the AI-generated response into chat.\n\n## Features\n- Triggered when a chat message is received\n- Uses Google Gemini (PaLM/Gemini Pro) via LangChain Agent\n- Optionally processes a Google Docs document\n- Modular design \u2013 easy to customize\n\n## \u2705 Requirements\n\n### Tools & Services Needed\n- `n8n` instance (self-hosted or n8n.cloud)\n- Google Gemini API (PaLM or Gemini Pro)\n- Google Sheets and Google Docs access\n- OAuth2 credentials for Google APIs configured in n8n\n\n\n## \ud83d\ude80 How to Use This Workflow\n### 1. Configure Webhook Chat Trigger\n**Node:** `When chat message received`\n- This node captures the user input message\n\n### 2. (Optional) Handle Google Docs Input\n\n**Node:** `Get a document in Google Docs`\n- If the user's message includes a link or ID of a Google Doc, this node retrieves and simplifies it\n- The LangChain Agent can call this automatically when it detects a document reference\n\n### 3. Generate AI Response\n\n**Node:** `Google Gemini Chat Model`\n- LangChain routes message through the Gemini model\n- It generates a smart, contextual response, optionally using tools (e.g., Docs reader)\n\n## \ud83d\ude4b For Help & Community\n\n- \ud83d\udc7e Discord: [n8n channel](https://discord.gg/9SDFKGnh2Y)\n- \ud83c\udf10 Website: [devcodejourney.com](https://devcodejourney.com)\n- \ud83d\udd17 LinkedIn: [Connect with Shakil](https://www.linkedin.com/in/shakilpg/)\n- \ud83d\udcf1 WhatsApp Channel: [Join Now](https://whatsapp.com/channel/0029Vb5l6JuDTkK5BRORNn0B)\n- \ud83d\udcac Direct Chat: [Message Now](https://wa.me/8801316320957)"
