Gmail AI Summarizer

This guide will walk you through building an AI-powered email summarization tool. The system automatically processes incoming emails from Gmail, and generates concise summaries using a Large Language Model (LLM), allowing you to quickly understand important information.

What You'll Build

A simple automation that triggers when a new email arrives in Gmail, processes the email content using an AI model, and generates a summary. This enables efficient email management by allowing users to quickly understand important details without reading lengthy messages.

Getting Started

1. Project Setup

1. Sign up at Lamatic.ai (opens in a new tab) and log in.
2. Navigate to the Projects and click New Project or select your desired project.
3. You'll see different sections like Flows, Context, and Connections

2. Creating a New Flow

1. Navigate to Flows, select New Flow.
2. Click Create from scratch to start with a blank canvas.

3. Setting Up the Gmail Trigger

1. Click "Choose a Trigger" or the + button.
2. Search for and select Gmail under the App nodes.
3. Configure the Gmail node:
   • Credentials: Select your Gmail OAuth credentials (or create new ones).

4. Adding AI Text Generation

1. Click the + icon below the Gmail node to add a new step.

2. Choose Generate Text (Text LLM).

3. Configure the AI model:

   • Model: Select a model (e.g., Gemini 2.0 Flash, GPT-4o).
   • Prompt: Enter a prompt to summarize the email. For example:

     Summarize this email content
   • Input: Insert the variable containing the email body. Click "Insert Variable" and select message_text from the Gmail node output.

   

5. Final Flow Overview

Your flow should look like this:

1. Gmail Trigger: Listens for new emails.
2. Generate Text: Summarizes the email content.

6. Test the Flow

1. Click Test on the Gmail node to fetch a sample email.
2. Click Test on the Generate Text node to see the summary generated from the sample email.

7. Deployment

1. Click the Deploy button in the top right corner.
2. Your flow is now live! It will automatically summarize new emails as they arrive.

8. What's Next?

• Send the Summary: Add another node (e.g., Slack, Email, or Notion) to send the generated summary to your preferred channel.
• Filter Emails: Add logic to only summarize emails from specific senders or with specific subjects.
• Experiment with Prompts: Refine the prompt to extract specific action items or formatting.

Now you have a working AI-powered email summarizer!
