Automated Document Processing and AI Chat Assistant

This n8n workflow automates the process of managing, analyzing, and utilizing documents within a Chat AI environment. It integrates Google Drive to monitor new or updated files in a specific folder, downloads and extracts content from different file types (PDF, Excel, Google Docs), and then stores this information in a vector database for retrieval. The workflow features a chat interface that allows users to ask questions, which are answered using retrieved relevant documents via a LangChain-powered AI agent, leveraging LLama models and Ollama embeddings for context-aware responses. Practical use cases include automated document ingestion, chat-based support systems, and knowledge base updates, making it ideal for teams managing large document repositories and seeking to enable AI-driven Q&A functionalities.
