Build a website-powered customer support chatbot with Decodo, Pinecone and Gemini

**Categories:** Business Automation, Customer Support, AI, Knowledge Management This comprehensive workflow enables businesses to build and deploy a custom-trained AI Chatbot in minutes. By combining a sophisticated data scraping engine with a RAG-based (Retrieval-Augmented Generation) chat interface, it allows you to transform website content into a high-performance support agent. Powered by **Google Gemini** and **Pinecone**, this system ensures your chatbot provides accurate, real-time answers based exclusively on your business data. ### **Benefits** * **Instant Knowledge Sync** - Automatically crawls sitemaps and URLs to keep your AI up-to-date with your latest website content. * **Embeddable Anywhere** - Features a ready-to-use chat trigger that can be integrated into the bottom-right of any website via a simple script. * **High-Fidelity Retrieval** - Uses vector embeddings to ensure the AI "searches" your documentation before answering, reducing hallucinations. * **Smart Conversational Memory** - Equipped with a 10-message window buffer, allowing the bot to handle complex follow-up questions naturally. * **Cost-Efficient Scaling** - Leverages Gemini’s efficient API and Pinecone’s high-speed indexing to manage thousands of customer queries at a low cost. ### **How It Works** 1. **Dual-Path Ingestion:** The process begins with an n8n Form where you provide a sitemap or individual URLs. The workflow automatically handles XML parsing and URL cleaning to prepare a list of pages for processing. 2. **Clean Content Extraction:** Using **Decodo**, the workflow fetches the HTML of each page and uses a specialized extraction node to strip away code, ads, and navigation, leaving only the high-value text content. **SignUp using:** [dashboard.decodo.com/register?referral_code=55543bbdb96ffd8cf45c2605147641ee017e7900](dashboard.decodo.com/register?referral_code=55543bbdb96ffd8cf45c2605147641ee017e7900). 3. **Vectorization & Storage:** The cleaned text is passed to the **Gemini Embedding** model, which converts the information into 3076-dimensional vectors. These are stored in a **Pinecone** "supportbot" index for instant retrieval. 4. **RAG-Powered Chat Agent:** When a user sends a message through the chat widget, an **AI Agent** takes over. It uses the user's query to search the Pinecone database for relevant business facts. 5. **Intelligent Response Generation:** The AI Agent passes the retrieved facts and the current chat history to **Google Gemini**, which generates a polite, accurate, and contextually relevant response for the user. ### **Requirements** * **n8n Instance:** A self-hosted or cloud instance of n8n. * **Google Gemini API Key:** For text embeddings and chat generation. * **Pinecone Account:** An API key and a "supportbot" index to store your knowledge base. * **Decodo Access:** For high-quality website content extraction. ### **How to Use** 1. **Initialize the Knowledge Base:** Use the Form Trigger to input your website URL or Sitemap. Run the ingestion flow to populate your Pinecone index. 2. **Configure Credentials:** Authenticate your Google Gemini and Pinecone accounts within n8n. 3. **Deploy the Chatbot:** Enable the Chat Trigger node. Use the provided webhook URL to connect the backend to your website's frontend chat widget. 4. **Test & Refine:** Interact with the bot to ensure it retrieves the correct data, and update your knowledge base by re-running the ingestion flow whenever your website content changes. ### **Business Use Cases** * **Customer Support Teams** - Automate answers to 80% of common FAQs using your existing documentation. * **E-commerce Sites** - Help customers find product details, shipping policies, and return information instantly. * **SaaS Providers** - Build an interactive technical documentation assistant to help users navigate your software. * **Marketing Agencies** - Offer "AI-powered site search" as an add-on service for client websites. ### **Efficiency Gains** * **Reduce Ticket Volume** by providing instant self-service options. * **Eliminate Manual Data Entry** by scraping content directly from the live website. * **Improve UX** with 24/7 availability and zero wait times for customers. **Difficulty Level:** Intermediate **Estimated Setup Time:** 30 min **Monthly Operating Cost:** Low (variable based on AI usage and Pinecone tier)

Create an all-in-one Discord assistant with Gemini, Llama Vision & Flux images

This n8n template demonstrates how to build **O'Carla**, an advanced all-in-one Discord AI assistant. It intelligently handles natural conversations, professional image generation, and visual file analysis within a single server integration. Use cases are many: Deploy a smart community manager that remembers past interactions, an on-demand artistic tool for your members, or an AI that can "read" and explain uploaded documents and images! ## Good to know * **API Costs:** Each interaction costs vary depending on the model used (Gemini vs. OpenRouter). Check your provider's dashboard for updated pricing. * **Infrastructure:** This workflow requires a separate Discord bot script (e.g., Node.js) to forward events to the n8n Webhook. It is recommended to host the bot using **PM2** for 24/7 uptime. ## How it works 1. **Webhook Trigger:** Receives incoming data (text and attachments) from your Discord bot. 2. **Intent Routing:** The workflow uses conditional logic to detect if the user wants an image (via keyword `gambar:`), a vision analysis (via attachments), or a standard chat. 3. **Multi-Model Intelligence:** * **Gemini 2.5:** Powers rapid and high-quality general chat reasoning. * **Llama 3.2 Vision (via OpenRouter):** Specifically used to describe and analyze images or text-based files. * **Flux (via Pollinations):** Uses a specialized AI Agent to refine prompts and generate professional-grade images. 4. **Contextual Memory:** A 50-message buffer window ensures O'Carla maintains the context of your conversation based on your Discord User ID. 5. **Clean UI Output:** Generated image links are automatically shortened via **TinyURL** to keep the Discord chat interface tidy. ## How to use 1. Connect your **Google Gemini** and **OpenRouter** API keys in the respective nodes. 2. Replace the Webhook URL in your bot script with this workflow's **Production Webhook URL**. 3. Type `gambar: [your prompt]` in Discord to generate images. 4. Upload an image or file to Discord to trigger the AI Vision analysis. ## Requirements * n8n instance (Self-hosted or Cloud). * Google Gemini API Key. * OpenRouter API Key. * Discord Bot Token and hosting environment. ## Customising this workflow O'Carla is highly flexible. You can change her personality by modifying the **System Message** in the Agent nodes, adjust the memory window length, or swap the LLM models to specialized ones like Claude 3.5 or GPT-4o.

AI chatbot for Max Messenger with voice recognition (GigaChat +SaluteSpeech)

**Name:** AI Chatbot for Max Messenger with Voice Recognition (GigaChat + Sber) **Description:** ### How it works This workflow powers an intelligent, conversational AI bot for Max messenger that can understand and respond to both **text and voice messages**. The bot uses GigaChat AI with built-in memory, allowing it to remember the conversation history for each unique user and answer follow-up questions. Voice messages are transcribed using Sber SmartSpeech. It's a complete solution for creating an engaging, automated assistant within your Max bot, using Russian AI services. ### Step-by-step * **Max Trigger:** The workflow starts when the **Max Trigger** node receives a new message sent to your Max bot. * **Access Control:** The **Check User** node verifies the sender's user ID against an allowed list. This prevents unauthorized users from accessing your bot. * **Access Denied Response:** If the user is not authorized, the **Access Denied** node sends a polite rejection message. * **Message Type Routing:** The **Text/Attachment** (Switch) node checks if the message contains plain text or has attachments (voice, photo, file). * **Attachment Processing:** If an attachment is detected, the **Download Attachment** (HTTP Request) node retrieves it, and the **Attachment Router** (Switch) node determines its type (voice, photo, or file). * **Voice Transcription:** For voice messages, the workflow gets a Sber access token via **Get Access Token** (HTTP Request), merges it with the audio file, and sends it to **Get Response** (HTTP Request) which uses Sber SmartSpeech API to transcribe the audio to text. * **Input Unification:** The **Voice to Prompt** node converts transcribed text into a prompt, while **Text to Prompt** does the same for plain text messages. Both paths merge at the **Combine** node. * **AI Agent Processing:** The unified prompt is passed to the **AI Agent**, powered by **GigaChat Model** and using **Simple Memory** to retain the last 10 messages per user (using Max `user_id` as the session key). * **Response Delivery:** The AI-generated response is sent back to the user via the **Send Message** node. ### Set up steps Estimated set up time: 15 minutes 1. **Get Max bot credentials:** Visit https://business.max.ru/ to create a bot and obtain API credentials. Add these credentials to **Max Trigger**, **Send Message**, and **Access Denied** nodes. 2. **Add GigaChat credentials:** Register for GigaChat API access and add your credentials to the **GigaChat Model** node. 3. **Add Sber credentials:** Obtain Sber SmartSpeech API credentials and add them to **Get Access Token** and **Get Response** nodes (HTTP Header Auth). 4. **Configure access control:** Open the **Check User** node and change the `user_id` value (currently 50488534) to your own Max user ID. This ensures only you can use the bot during testing. 5. **Customize bot personality:** Open the **AI Agent** node and edit the system message to change the bot's name, behavior, and add your own contact information or links. 6. **Test the bot:** Activate the workflow and send a text or voice message to your Max bot to verify it responds correctly. ### Notes This workflow is specifically designed for Russian-speaking users and uses Russian AI services (GigaChat and Sber SmartSpeech) as alternatives to OpenAI. Make sure you have valid API access to both services before setting up this workflow.
