Telegram AI Support Bot (GPT-4 mini) + Google Docs Knowledge

Turn Your Telegram Support Into an AI Agent That Answers From Your Google Docs

This Telegram AI Support Bot (GPT-4 mini) + Google Docs Knowledge n8n workflow turns incoming customer messages into instant, accurate AI replies. Your bot reads your business documentation from Google Docs and responds in plain conversational language—so you can deliver 24/7 support with zero code.

What this workflow does

• Telegram Trigger captures messages from users who contact your Telegram bot.
• Langchain AI Agent (OpenAI GPT) interprets each request and generates an answer using RAG (retrieval-augmented generation).
• Google Docs Tool connects to your specified Google Doc (such as FAQ, SOPs, or policies) and retrieves relevant context.
• Memory Buffer keeps track of recent chat history to support more human-like follow-ups.
• Telegram Reply Node sends the AI-generated response back to the customer.
