I Built a Personal Assistant AI Agent with No Code in n8n

Film & Animation

Introduction

I'm excited to share my latest project with all of you—a Personal Assistant AI agent built using n8n, a no-code automation tool that can transform the way I manage my business, especially in personal administration tasks. Unlike a human assistant, my AI agent is available 24/7, can respond immediately, and is much more cost-effective than hiring a human personal assistant.

Overview of the AI Agent

The AI agent is integrated with Telegram, allowing me to interact with it via my mobile or desktop app. I simply use Telegram to send requests like scheduling events, summarizing emails, or updating project statuses, and the AI agent takes care of the rest. It executes various workflows built within n8n and provides timely responses.

For example, if I'm running late to a meeting, I can quickly ask my agent to summarize my unread emails. The AI agent scans my inbox for unread emails from today, summarizes their contents, and provides me with an overview.

Workflow Components

The architecture of my AI agent comprises several key components:

  1. **OpenAI Chat Model:** I’m using GPT-4 for natural language understanding, which serves as the brains of the agent.
  2. Vector Store: This is connected through Pinecone, where I keep contact information for easy email sending.
  3. Various Tools: I’ve developed multiple tools within n8n, such as "get emails," "send email," "get calendar," "set calendar," "update database," and "summarize database."

Demo: Summarizing Emails

To illustrate the agent's capabilities, let’s walk through a demo of summarizing emails. When I send the command "Can you summarize my emails from today?", the workflow is triggered, fetching unread emails from my inbox. The AI processes this query through the OpenAI node and returns a concise summary, detailing the sender and the content of each email.

Workflow Execution Breakdown

In the email summarization workflow, the following happens:

  1. A message triggers the workflow in the agent.
  2. It retrieves the current date to filter emails marked as unread.
  3. The emails are pulled from Gmail, filtered to those received after the specified date.
  4. Finally, another OpenAI node summarizes these emails for a swift response.

This same pattern is used throughout the different functionalities of the agent, whether it’s sending an email, managing calendar events, or updating a Google Sheets database.

Sending Emails with the Agent

To demonstrate sending an email, I asked the agent, "Can you send an email to Colin asking how the project is coming along?" The AI efficiently processes this request, outputs the email contents, and then confirms that the email has been successfully sent.

Calendar Management

The AI agent can also handle calendar events. For instance, I can ask it to retrieve my calendar events for tomorrow. The agent retrieves the data and summarizes it, providing a comprehensive overview of my schedule.

Additionally, the agent can schedule new events. When prompted to set an event with Colin for 5 PM today, it parses the required information and creates the event on my calendar, providing real-time updates.

Database Management

My AI agent interacts with a Google Sheets database, allowing for easy updates and summaries of project statuses. For instance, after completing a project, I can say, "Can you update the notes and status of the AI tool project to complete?" The agent identifies the project and updates the corresponding rows, reflecting changes in real-time.

Summarizing Database Information

Lastly, the AI can summarize the entire database. A command like "Please summarize our database" will pull all relevant project information and provide a concise summary of statuses and updates.

Conclusion

Building this AI agent with n8n offers me an efficient alternative to manual administrative tasks. The tools and workflows can continuously evolve and improve. As I incorporate more features, this agent will become even smarter and more capable, serving as an invaluable resource for managing both work and personal tasks.

By integrating various functionalities, I'm able to streamline my workload significantly. I encourage you to explore n8n and see how easily you can implement such workflows for your own needs!
