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.

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.
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.
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.
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.
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.

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.

Initialize the Knowledge Base: Use the Form Trigger to input your website URL or Sitemap. Run the ingestion flow to populate your Pinecone index.
Configure Credentials: Authenticate your Google Gemini and Pinecone accounts within n8n.
Deploy the Chatbot: Enable the Chat Trigger node. Use the provided webhook URL to connect the backend to your website's frontend chat widget.
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.
