Automate Telegram Customer Support with GPT-4o-mini and Google Docs

The Latenode automation creates a Telegram-based customer support bot that leverages GPT-4o-mini and a designated Google Docs knowledge base to provide accurate and contextual responses to user queries.

The bot captures incoming messages from Telegram, processes them using an AI agent based on OpenAI's GPT, retrieves relevant information from the specified Google Doc, and responds back to the user within the Telegram chat interface. This no-code solution enables businesses to offer 24/7 customer support with minimal maintenance, drawing upon their existing documentation to power an intelligent, conversational support experience.
