Create Professional Email Drafts with GPT-4, Telegram, and Contact Database

This n8n workflow automates the process of generating professional email drafts using AI (GPT-4), triggered by messages in Telegram, and leveraging a contact database (Google Docs) for context. It simplifies email creation, making it faster and more personalized.

What it does

  1. Listens for Telegram Messages: The workflow starts when a new message is received in a configured Telegram bot.
  2. Processes Input with Code: A Code node extracts relevant information from the Telegram message, likely preparing it for the AI agent.
  3. Loads Contact Data from Google Docs: It retrieves contact information from a specified Google Docs document, which serves as a contact database.
  4. Embeds Contact Data with OpenAI: The contact data is then processed by an OpenAI Embeddings model, converting it into a numerical representation suitable for vector search.
  5. Stores Embeddings in Pinecone: The generated embeddings are stored in a Pinecone Vector Store, enabling efficient semantic search of contact information.
  6. Generates Email Draft with AI Agent (GPT-4): An AI Agent (likely configured with GPT-4) uses the Telegram message content and the context from the Pinecone vector store to generate a professional email draft.
  7. Sends Draft via Telegram: The generated email draft is sent back to the user in Telegram.
  8. Sends Draft via Gmail: The generated email draft is also sent as a new email via Gmail.

Prerequisites/Requirements

  • n8n Instance: A running n8n instance.
  • Telegram Bot: A Telegram bot token and chat ID configured for the Telegram Trigger and Telegram nodes.
  • OpenAI API Key: An API key for OpenAI to use the Embeddings and Chat Model.
  • Pinecone Account: An API key and environment for Pinecone to store and retrieve vector embeddings.
  • Google Docs Account: Access to a Google Docs document containing your contact database.
  • Gmail Account: A Gmail account configured for sending emails.

Setup/Usage

  1. Import the Workflow: Import the provided JSON into your n8n instance.
  2. Configure Credentials:
    • Telegram: Set up your Telegram Bot API credentials for both the "Telegram Trigger" and "Telegram" nodes.
    • OpenAI: Configure your OpenAI API key for the "Embeddings OpenAI" and "OpenAI Chat Model" nodes.
    • Pinecone: Set up your Pinecone API key and environment for the "Pinecone Vector Store" node.
    • Google Docs: Configure your Google Docs credentials for the "Google Docs" node, linking it to your contact database document.
    • Gmail: Set up your Gmail credentials for the "Gmail" node.
  3. Customize Google Docs: Ensure your Google Docs document is structured in a way that the "Default Data Loader" can effectively process it for contact information.
  4. Activate the Workflow: Once all credentials and configurations are set, activate the workflow.
  5. Trigger the Workflow: Send a message to your configured Telegram bot with your email request. The AI will then generate and send you a draft via Telegram and Gmail.
