Introduction to N8N and AI Agents

Introduction to N8N and AI Agents N8N is one of the leading platforms for developing agents, and with it, you can create a digital employee that can autonomously take on tasks, make decisions, and work with other systems.

Creating a New Workflow in N8N

Creating a New Workflow To start, you need to create a new workflow in N8N. This is done by clicking on the "Create" button, which will give you a canvas to work with. You can then add different modules to your workflow, similar to how you would in Make.

Adding the Chat Message Connector

Chat Message Connector The first step is to add the chat message connector, which will trigger the agent to execute when it receives a new message. You can then add the AI agent, which will be the brain of your digital employee.

Adding the AI Agent

AI Agent N8N offers different agents, including a tools agent that can access different functions, conversation agents, and open AI agents. For this example, we will start with the tools agent.

Adding the Chat Model

Chat Model The chat model controls which language model (LLM) the agent uses. For simplicity, we will use the Open AI chat model, but you can also use other models such as Azure Open AI or Google Gemini.

Testing the Agent

Testing the Agent You can now test the agent by asking it a simple question. The agent will execute and provide an answer. However, the agent does not yet understand the conversation and will forget the previous message.

Adding Memory to the Agent

Adding Memory To solve this problem, you need to add a memory to the agent. This is done by clicking on the plus button and selecting the window buffer memory. You can then enter how many previous messages the agent should remember.

Accessing Google with the Agent

Accessing Google The agent can now access Google using the SERP API tool. This tool gives you access to the Google search, and you can set the country and other parameters.

Testing the Agent with Google Access

Testing the Agent with Google Access You can now test the agent by asking it a question that requires access to Google. The agent will execute the API tool and provide an answer with links to relevant news broadcasts.

Adjusting the Prompt

Adjusting the Prompt To improve the answer, you can adjust the prompt by telling the agent directly what date it is today. This is done using variables, and you can select the current date from the system message.

Testing the Agent with the Adjusted Prompt

Testing the Agent with the Adjusted Prompt You can now test the agent again, and it will provide a message based on the prompt you gave. The agent will generate a message with relevant information for entrepreneurs in Germany.
