Telegram Multi-Provider AI Chat Agent (n8n) | Claude, GPT & Gemini

Turn your Telegram bot into a multi-provider AI chat agent—Claude, GPT, Gemini (and OpenRouter) from n8n

This n8n workflow creates a Telegram AI assistant that automatically routes each message to your chosen model provider, keeps per-user chat history, and supports commands to manage settings, search simulation, and conversation export—right inside Telegram.

What this workflow does

• Triggers on new messages/callbacks: Starts when a new Telegram message (or callback query) is sent to your bot.
• Parses chat context and commands: Extracts chat/user identifiers, message text, and an optional slash command with arguments.
• Routes to the right handler: Supports help/welcome responses, settings changes (provider, model, temperature, system prompt), and chat history controls (new chat, list history, clear).
• Maintains per-user conversation history: Appends messages to workflow static data so each user’s chat context is preserved.
• Calls the selected AI provider: Sends the prepared prompt to Anthropic Claude, OpenAI GPT, Google Gemini, or OpenRouter using the configured model and temperature.
• Returns results to Telegram: Extracts the assistant text from the provider response, saves it to history, and replies in Telegram with inline actions such as Regenerate and Stop.

Use cases

• Offer a Telegram “AI support” bot where users can switch between Claude, GPT, Gemini, or OpenRouter.
• Give operators an interactive way to tune system prompt, model, and temperature without redeploying the workflow.
• Enable conversation export and lightweight “simulated web search” responses as part of the chat experience.

Technical details

• Works with Telegram (Telegram Trigger + message/callback handling).
• Uses core n8n building blocks including Set, Code, Switch, Telegram, and HTTP Request (for provider API calls).
• Includes workflow static data for per-user chat history persistence.
• Supports provider credentials for Anthropic, OpenAI, Google Gemini, and/or OpenRouter.
