Personalized AI Assistant with Voice Support & Integrations

This n8n workflow creates a personalized AI assistant that can respond to chat messages, utilize various tools, and integrate with external services like Telegram. It leverages LangChain agents to provide dynamic, context-aware responses and actions.

Description

This workflow acts as a central hub for an AI assistant, capable of understanding user queries, routing them to appropriate AI models and tools, and delivering responses. It's designed to be highly extensible, allowing for the addition of more tools and integrations to enhance its capabilities.

What it does

1. Listens for Chat Messages: The workflow is triggered whenever a new chat message is received via the "Chat Trigger" node.
2. Initial Field Editing: It then processes the incoming chat message, potentially modifying or adding fields to the payload for further processing.
3. Routes Messages to AI Agent: The core logic is handled by an "AI Agent" (LangChain Agent) that receives the processed chat message.
4. AI Agent Configuration:
   • Memory: The agent uses a "Simple Memory" (Buffer Window Memory) to maintain conversational context across interactions.
   • Language Model: It can be configured to use either an "OpenAI Chat Model" or an "Anthropic Chat Model" (e.g., Claude) for generating responses and understanding intent.
   • Tools: The AI Agent is equipped with several tools to perform specific tasks:
     • Calculator: For mathematical computations.
     • SerpApi (Google Search): To perform web searches and retrieve information.
     • Wikipedia: To look up information from Wikipedia.
5. Conditional Response Handling: After the AI Agent processes the message and potentially uses its tools, a "Switch" node is used to determine the next action based on the AI's output.
6. Sends Telegram Messages: If the AI Agent generates a response, it is sent back to the user via a "Telegram" node.

Prerequisites/Requirements

• n8n Instance: A running n8n instance.
• Telegram Bot: A Telegram bot token and chat ID to send and receive messages.
• OpenAI API Key or Anthropic API Key: Depending on which chat model you choose to use.
• SerpApi API Key: Required for the Google Search tool.
• Wikipedia: No specific API key is usually required, but internet access for the n8n instance is necessary.

Setup/Usage

1. Import the Workflow: Import the provided JSON into your n8n instance.
2. Configure Credentials:
   • Telegram: Set up your Telegram Bot credential with your bot token and chat ID.
   • OpenAI/Anthropic: Configure your OpenAI or Anthropic Chat Model credential with your respective API key.
   • SerpApi: Set up your SerpApi credential with your API key.
3. Activate the Workflow: Ensure the workflow is active to start listening for chat messages.
4. Interact with the Bot: Send messages to your configured Telegram bot, and the AI assistant will process them, use its tools if necessary, and respond.

This workflow provides a powerful foundation for building advanced conversational AI assistants with integrated capabilities.
