🧑‍💼 Who is this for?

This workflow is for anyone who receives too many emails and wants to stay informed without drowning in their inbox.

If you're constantly checking your Gmail and wish you had someone summarizing messages and sending just the important parts to your phone, this is for you. Especially useful for solopreneurs, customer support, busy professionals, or newsletter addicts.

🧠 What problem is this workflow solving?

Email is powerful, but also overwhelming. Important info gets buried in threads, and staying on top of things can mean hours wasted scanning messages.

This workflow turns that chaos into clarity: as soon as a new email arrives, you get a concise AI-generated summary in Telegram — straight to your pocket.

No more checking Gmail constantly. No more missing key updates. Just a clean, human-style summary, written in the language you choose.

⚙️ What this workflow does

  • Watches your Gmail inbox for new messages
  • Prepares the content, including sender, subject, and message body
  • Sends it to OpenAI to generate a friendly, casual summary
  • Delivers that summary to your Telegram chat

All in seconds, completely automated.

🛠️ Setup

  1. Connect your accounts: Gmail, Telegram, and OpenAI credentials must be added to the respective nodes.
  2. Set your Telegram chat ID: Use a bot like @userinfobot to get it.
  3. Customize the language in the Set summary language node (default is English).
  4. Activate the workflow — and watch it go.

🧩 How to customize this workflow to your needs

You can make this workflow your own in a few easy ways:

  • Summarize only some emails: Add a Filter node after the Gmail trigger (e.g., only messages from certain senders).
  • Change the tone or detail of summaries: Tweak the system prompt in the Summary generation agent.
  • Use a different model: Swap OpenAI’s GPT-4o for another provider like Claude or DeepSeek.
  • Translate to your preferred language: Just change "english" to "español", "français", etc.

Gmail to Telegram Email Summaries with OpenAI GPT-4o

This n8n workflow automates the process of summarizing new emails received in Gmail and sending these summaries to a Telegram chat. It leverages OpenAI's GPT-4o model for intelligent summarization, ensuring you stay informed without having to read every email in full.

What it does

This workflow simplifies email management by:

  1. Monitoring Gmail: It continuously checks for new emails in your specified Gmail inbox.
  2. Extracting Email Content: For each new email, it extracts the subject, sender, and body content.
  3. Summarizing with AI: It sends the extracted email content to an OpenAI GPT-4o model, requesting a concise summary.
  4. Formatting the Summary: It formats the AI-generated summary along with the original email details into a readable message.
  5. Sending to Telegram: Finally, it posts the formatted email summary to a designated Telegram chat.

Prerequisites/Requirements

To use this workflow, you will need:

  • n8n Instance: A running instance of n8n.
  • Gmail Account: Connected to n8n with appropriate permissions to read emails.
  • Telegram Bot Token: A Telegram bot and its API token to send messages.
  • OpenAI API Key: An API key for OpenAI, with access to the GPT-4o model.

Setup/Usage

  1. Import the Workflow:
    • Download the provided JSON file.
    • In your n8n instance, go to "Workflows" and click "New".
    • Click the "Import from JSON" button and paste the workflow JSON or upload the file.
  2. Configure Credentials:
    • Gmail Trigger: Configure your Gmail OAuth2 credentials. Ensure it has access to read your emails.
    • OpenAI Chat Model: Configure your OpenAI API Key credential.
    • Telegram: Configure your Telegram Bot API credential. You will need your Bot Token and the Chat ID where you want to receive the summaries.
  3. Activate the Workflow:
    • Once all credentials are set up, save the workflow.
    • Toggle the workflow to "Active" to start it.
  4. Customize (Optional):
    • Gmail Trigger: You can adjust the "Query" field in the Gmail Trigger node to filter for specific emails (e.g., is:unread from:important@example.com).
    • AI Agent: The "AI Agent" node is configured to use the "OpenAI Chat Model". You can customize the prompt given to the AI to refine the summaries further if needed.
    • Edit Fields (Set): This node is currently empty but can be used to add or modify data before sending it to Telegram, for example, to add a custom prefix to the message.
    • Telegram: Adjust the message format in the Telegram node if you want to change how the summary appears.

The workflow will now automatically process new emails, summarize them using AI, and send them to your Telegram chat.

Create an AI Telegram bot using Google Drive, Qdrant, and OpenAI GPT-4.1

How it works This workflow creates an intelligent Telegram bot with a knowledge base powered by Qdrant vector database. The bot automatically processes documents uploaded to Google Drive, stores them as embeddings, and uses this knowledge to answer questions in Telegram. It consists of two independent flows: document processing (Google Drive → Qdrant) and chat interaction (Telegram → AI Agent → Telegram). Step-by-step Document Processing Flow: New File Trigger: The workflow starts when the New File Trigger node detects a new file created in the specified Google Drive folder (polling every 15 minutes). Download File: The Download File (Google Drive) node downloads the detected file from Google Drive. Text Splitting: The Split Text into Chunks node splits the document text into chunks of 3000 characters with 300 character overlap for optimal embedding. Load Document Data: The Load Document Data node processes the binary file data and prepares it for vectorization. OpenAI Embeddings: The OpenAI Embeddings node generates vector embeddings for each text chunk. Insert into Qdrant: The Insert into Qdrant node stores the embeddings in the Qdrant vector database collection. Move to Processed Folder: After successful processing, the Move to Processed Folder (Google Drive) node moves the file to a "Qdrant Ready" folder to keep files organized. Telegram Chat Flow: Telegram Message Trigger: The Telegram Message Trigger node receives new messages from the Telegram bot. Filter Authorized User: The Filter Authorized User node checks if the message is from an authorized chat ID (26899549) to restrict bot access. AI Agent Processing: The AI Agent receives the user's message text and processes it using the fine-tuned GPT-4.1 model with access to the Qdrant knowledge base tool. Qdrant Knowledge Base: The Qdrant Knowledge Base node retrieves relevant information from the vector database to provide context for the AI agent's responses. Conversation Memory: The Conversation Memory node maintains conversation history per chat ID, allowing the bot to remember context. Send Response to Telegram: The Send Response to Telegram node sends the AI-generated response back to the user in Telegram. Set up steps Estimated set up time: 15 minutes Google Drive Setup: Add your Google Drive OAuth2 credentials to the New File Trigger, Download File, and Move to Processed Folder nodes. Create two folders in your Google Drive: one for incoming files and one for processed files. Copy the folder IDs from the URLs and update them in the New File Trigger (folderToWatch) and Move to Processed Folder (folderId) nodes. Qdrant Setup: Add your Qdrant API credentials to the Insert into Qdrant and Qdrant Knowledge Base nodes. Create a collection in your Qdrant instance (e.g., "Test-youtube-adept-ecom"). Update the collection name in both Qdrant nodes. OpenAI Setup: Add your OpenAI API credentials to the OpenAI Chat Model and OpenAI Embeddings nodes. (Optional) Replace the fine-tuned model ID in OpenAI Chat Model with your own model or use a standard model like gpt-4-turbo. Telegram Setup: Create a Telegram bot via @BotFather and obtain the bot token. Add your Telegram bot credentials to the Telegram Message Trigger and Send Response to Telegram nodes. Update the authorized chat ID in the Filter Authorized User node (replace 26899549 with your Telegram user ID). Customize System Prompt (Optional): Modify the system message in the AI Agent node to customize your bot's personality and behavior. The current prompt is configured for an n8n automation expert creating social media content. Activate the Workflow: Toggle "Active" in the top-right to enable both the Google Drive trigger and Telegram trigger. Upload a document to your Google Drive folder to test the document processing flow. Send a message to your Telegram bot to test the chat interaction flow.
