This n8n workflow creates an intelligent, AI-powered document chatbot capable of handling multiple file formats and providing contextual responses. It integrates with various AI services, including OpenAI and Google Gemini, to interpret and analyze uploaded files, then uses memory buffers to maintain conversational context. Users can submit questions or upload documents through a webhook, prompting the workflow to process files, generate embeddings, and retrieve relevant information for accurate answers. This setup is ideal for creating interactive bots that assist with document inquiries, automate document analysis, or enhance customer support with AI-driven insights.
