specified Google Drive folder you can chose.\n\n**Process:**\nFile Upload\nThe company owner uploads a .txt or other document file containing essential company information to the Google Drive folder.\n\n**Download**\nThe file is automatically downloaded from Google Drive once detected.\n\n**Chunking and Parsing**\nThe content is split using a recursive character splitter (chunk size: 500, overlap: 20), then loaded and prepared for embeddings.\n\n**Embedding Generation**\nUsing OpenAI embeddings, the file content is transformed into vector representations.\n\n**Storage in Pinecone**\nThe resulting embeddings are inserted into the \u201cgoldsmith\u201d index within Pinecone under the namespace Q&A.\n\n**Purpose:**\nThis structured knowledge will later be used in Part

"## Part Two \u2013 AI Chatbot for Lead Capture and Business Q&A\nThis workflow enables a chatbot assistant for the goldsmith business Gold Digger, allowing it to answer customer inquiries and collect leads in an automated, intelligent way.\n\n**Trigger:**\nThe workflow is initiated when a customer sends a message to the public AI chat endpoint.\n\n**Process:**\nAI Assistant Activation\nA chat agent is triggered with a system prompt instructing it to act as a friendly assistant for you business. It uses tools intelligently to assist with:\n\nBusiness details (e.g., products, opening hours, services).\n\nCollecting lead data (name, email, interests, phone number).\n\n**Contextual Memory**\nA memory buffer is used to maintain conversation context (window of 12 messages), enabling coherent multi-turn dialogues.\n\n**Knowledge Retrieval**\nThe agent leverages the newCompany_q tool, which accesses a Pinecone vector store populated in Part One. This allows the chatbot to answer questions based on the uploaded company data.\n\n**AI Model**\nGPT-4o is used to generate natural and accurate responses throughout the conversation.\n\n**Lead Capture**\nWhen a user shows interest, the agent collects their:\nName, Email, Phone\n\n**Specific interests**\nThis information is then automatically stored in a connected Google Sheet\n\n**Purpose:**\nThis chatbot workflow acts as a digital front desk, available 24/7 to answer frequently asked questions and collect potential customer information. It streamlines lead generation and boosts customer engagement by providing instant, intelligent responses.\nYou can easily integrate this chatbot into your company website to enhance user experience and automate customer support.\n\n" }, "typeVersion": 1 } ], "active": false, "settings": { "executionOrder": "v1" }, "versionId": "cd9bd04e-8114-474b-a8a7-3802a869811f", "connections": { "Google Drive": { "main": [ [ { "node": "Pinecone Vector Store", "type": "main", "index": 0 } ] ] }, "newCompany_q": { "ai_tool": [ [ { "node": "AI Agent", "type": "ai_tool", "index": 0 } ] ] }, "Embeddings OpenAI": { "ai_embedding": [ [ { "node": "Pinecone Vector Store", "type": "ai_embedding", "index": 0 } ] ] }, "OpenAI Chat Model": { "ai_languageModel": [ [ { "node": "AI Agent", "type": "ai_languageModel", "index": 0 } ] ] }, "Embeddings OpenAI1": { "ai_embedding": [ [ { "node": "Pinecone Vector Store1", "type": "ai_embedding", "index": 0 } ] ] }, "OpenAI Chat Model1": { "ai_languageModel": [ [ { "node": "newCompany_q", "type": "ai_languageModel", "index": 0 } ] ] }, "Default Data Loader": { "ai_document": [ [ { "node": "Pinecone Vector Store", "type": "ai_document", "index": 0 } ] ] }, "Google Drive Trigger": { "main": [ [ { "node": "Google Drive", "type": "main", "index": 0 } ] ] }, "Window Buffer Memory": { "ai_memory": [ [ { "node": "AI Agent", "type": "ai_memory", "index": 0 } ] ] }, "Pinecone Vector Store1": { "ai_vectorStore": [ [ { "node": "newCompany_q", "type": "ai_vectorStore", "index": 0 } ] ] }, "When chat message received": { "main": [ [ { "node": "AI Agent", "type": "main", "index": 0 } ] ] }, "Recursive Character Text Splitter": { "ai_textSplitter": [ [ { "node": "Default Data Loader", "type": "ai_textSplitter", "index": 0 } ] ] }, "Append row in sheet in Google Sheets": { "ai_tool": [ [ { "node": "AI Agent", "type": "ai_tool", "index": 0 } ] ] } } }
