AI-Powered Customer Support Telegram Bot with Google Docs Integration

This n8n workflow transforms a Telegram bot into an intelligent customer support agent that leverages Google Docs to reference important business information. When users send messages to the bot, the workflow activates, capturing the message through a Telegram trigger. The message is then processed by a Langchain AI agent powered by OpenAI’s GPT-4, which interprets the query and uses retrieval-augmented generation (RAG) techniques to provide accurate responses. A connected Google Doc serves as a dynamic knowledge base, offering context and details such as FAQs, policies, or procedures. The conversation history is maintained using a memory buffer, enabling more natural and context-aware interactions. The AI-generated response is finally sent back to the user on Telegram, creating a seamless, no-code support experience. This workflow is ideal for businesses seeking automated, 24/7 customer support, internal helpdesk bots, or onboarding assistants, all with easy setup and extensibility to other messaging platforms.
