Estimated reading time: 7 minutes

These days, efficiency and integration are crucial for companies of all sizes. It is in this scenario that n8n stands out as one of the main automation and integration tools available.

Rapidly gaining popularity, n8n offers innovative solutions that leverage native integrations with artificial intelligence and the creation of autonomous agents. Let's explore in detail how this tool can transform your approach to automation.

What is N8N?

The n8n is a automation and integration platform which facilitates communication between different systems used on a daily basis. With over 400 ready-made integrations, n8n lets you create your own automations and integrations as needed.

Furthermore, one of the great attractions of n8n is its cost: you can use it for free, a significant advantage, especially for users in Brazil.

Automation and Integration: Fundamental Concepts

Before we delve deeper into n8n, it's important to understand what automations and integrations are. Automation refers to actions that occur without the need for human intervention, generally performed by servers.

These actions are triggered by triggers, such as receiving an email or obtaining information from a system. Integration, on the other hand, involves communication between different systems, often facilitated by APIs and webhooks.

N8N and Other Tools

There's a lot automation and integration tools available, such as Make and Zapier. Each has its own advantages and disadvantages, but n8n stands out for its flexibility and the fact that it allows you to create custom integrations.

Additionally, n8n is especially popular among technical teams due to its ability to embed code when needed.

N8N Interface and Features

The n8n interface is intuitive and allows the creation of complex automations through a visual panel. You can add modules from different services, such as Gmail, OpenAI, Instagram, Facebook, among others, to create automated workflows. Below, we explore some of n8n's most notable features.

Native Artificial Intelligence Integrations

One of the features that make n8n stand out is its native integration with artificial intelligence tools. This allows the creation of autonomous agents that can perform complex tasks.

For example, automatically responding to emails or extracting information from websites. Integration with frameworks like LangChain makes it easy to build custom AI applications directly on the n8n platform.

Flexibility and Customization

n8n allows you to embed code such as JavaScript and Python, offering flexibility that many other tools do not have. This is ideal for users who need highly customized solutions.

However, even without advanced programming knowledge, you can use n8n's visual interface to configure your automations.

Usage Example: Email Automation

To illustrate how n8n works, consider a simple workflow for automating email responses. When an email is received, it triggers a trigger in n8n.

Then, an integration with OpenAI can determine if the email requires a response. If necessary, n8n generates an automated response and saves it as a draft in Gmail, ready for review and sending.

N8N Pre-Made Templates and Integrations

n8n offers over 400 out-of-the-box integrations covering a wide range of services, from Google Sheets and Telegram to databases like MySQL and PostgreSQL. These templates make it easy to create automations without having to start from scratch, saving time and effort.

Gmail Integrations

For example, when integrating with Gmail, you can configure actions such as adding a tag, deleting an email, marking it as read or unread, replying to emails, and much more. These actions can be combined into complex workflows to completely automate email management.

Artificial Intelligence and LangChain

The recent integration of n8n with the LangChain framework allows you to create AI agents in a visual and simplified way. With this functionality, you can develop chatbots, personalized assistants, information extraction tools, and much more.

Additionally, it supports a variety of AI models including OpenAI, Google, Anthropic, and Llama.

N8N Price and Usage Models

n8n offers both a cloud service and a self-hosted option. In the cloud model, you pay a monthly fee based on the number of workflows and executions.

However, the self-hosted option allows you to host n8n on your own machine, eliminating additional costs except those associated with maintaining your server.

Pricing Plans

Cloud service pricing plans vary depending on the number of active automations and workflows. For example, the Starter plan allows 2,500 runs and five active workflows for $100 per month.

The Pro plan offers 10,000 executions and 15 active workflows, as well as advanced features such as global variables and user administration.

User Interface

n8n's interface is designed to be easy to use, even for those without technical experience. You can add modules, configure triggers and actions, and connect different services with just a few clicks.

The interface also allows visualization of workflows, making it easier to identify points of improvement and necessary adjustments.

Interface Example

In the n8n interface, you can start with a simple trigger, like receiving an email. From there, you can add modules to analyze the email, see if it requires a response, generate an AI-powered response, and save the response as a draft. Each module can be adjusted and configured as needed, providing great flexibility.

Conclusion

n8n is a powerful and versatile tool that can transform the way you manage automations and integrations. With its wide range of out-of-the-box integrations, artificial intelligence support, and customization options, this tool offers a robust solution for businesses of all sizes.

If you are looking optimize processes and improve efficiency, the n8n could be the ideal tool for your needs. For those interested in exploring further, we recommend visiting the official website and trying the free version.
