N8N Telegram Support Bot: Google Docs + Claude Q&A

Turn your Google Docs into a Telegram support chatbot powered by Claude

This n8n workflow answers Telegram customer questions using the latest content from your Google Docs, generates responses with Anthropic Claude, and automatically logs every Q&A to Google Sheets—then replies back in Telegram.

What this workflow does

• Listens for new Telegram messages sent to your bot.
• Fetches the latest text from a specified Google Docs document to serve as the knowledge source.
• Builds an AI prompt by combining today’s date, the Google Docs content, and the user’s Telegram question.
• Sends the prompt to an Anthropic Claude chat model using an AI Agent with conversation memory keyed by Telegram chat ID.
• Cleans the AI response text (for example, flattening Markdown links) for a clean Telegram reply.
• Logs each interaction to a Google Sheets spreadsheet: date, question, answer, chat ID, and username.
• Replies in Telegram with the final processed answer.

Use cases

• Provide instant Telegram support for your SaaS using an internal help document stored in Google Docs.
• Reduce repetitive support work by answering common questions from a living knowledge base.
• Maintain an audit trail of customer questions and Claude answers in Google Sheets for review and improvement.
• Support team members who want a quick, conversational interface to documentation without rebuilding a UI.
