What is n8n and how does it integrate with AI in 2025

n8n has established itself as a workflow automation platform that stands out for its API-first approach and node-based architecture. Unlike other automation tools, n8n is not simply a “free Zapier”, but a professional solution that allows you to orchestrate complex processes with the simplicity of a flowchart.

Visual automation with intelligent nodes

The n8n system works through interconnected nodes that act as specialized units. Each node represents a specific action: querying an API, sending an email, processing data, or executing scripts. By combining these nodes, you create custom workflows without advanced coding.

For integration with AI, n8n has developed specific nodes that interact with language models (LLMs) such as OpenAI, Google Cloud AI, and open-source models through Ollama. These nodes allow you to create autonomous agents that combine:

  • A “brain” based on LLMs
  • Memory systems (short and long-term)
  • Task planning and decomposition capabilities
  • Integration with external tools via APIs

Its drag-and-drop interface makes it easy to create complex flows, allowing people with little programming experience to develop powerful solutions.

Advantages of the open-source model in flows with AI

n8n operates under a “fair-code” model, offering significant advantages for AI implementations. This approach allows you to access the source code and self-host the platform to have full control over your data.

This feature is especially valuable for organizations concerned about security and privacy. By hosting n8n on your own servers, you reduce the costs associated with proprietary solutions and eliminate the limitations imposed by other platforms.

The flexibility of n8n allows you to add custom code in JavaScript or Python, use external libraries, or import cURL requests, extending the capabilities of your AI agents. This combination of visual automation with technical extensibility positions n8n as the ideal tool for creating AI solutions tailored exactly to your specific needs.

Key components for AI-powered automatic flows

To create effective automatic flows with n8n, you need to understand the fundamental components that power its integration with artificial intelligence. These elements work together to turn repetitive tasks into intelligent, autonomous processes.

AI Nodes: Integration with LLM Models

AI nodes are the brains of your automatic flows in n8n. The platform has expanded its capabilities through native integration with various language models (LLMs). You can easily connect to APIs from OpenAI, Anthropic, Cohere, and Google Vertex AI, as well as local models through Ollama. These nodes allow your flows to interpret natural language, generate coherent text, and reason about available information, functioning as the nerve center of your automations.

Processing Unstructured Data with NLP

A significant advantage of n8n is its ability to handle unstructured data using natural language processing (NLP). This allows you to automate tasks such as sorting emails, analyzing sentiment in social media comments, or extracting relevant information from PDF documents. You can implement text summarization or machine translation capabilities that turn complex data into actionable insights for your business.

Contextual Memory and Adaptive Learning

Contextual memory is essential for your AI agents to have consistent and personalized conversations. N8N offers several types of memory:

  • Short-term memory: Retains information during a current conversation
  • Persistent memory: Stores data in databases such as PostgreSQL or Supabase
  • Relational Memory: Connect previous interactions with specific users

This capability allows your flows to remember past interactions, improving with each interaction through adaptive learning. You can configure the “Context Window Length” to define how many previous messages the agent will remember, optimizing its performance.

Custom code integration in JavaScript or Python

For more sophisticated flows, n8n includes code nodes that allow you to run custom scripts in JavaScript or Python. This functionality gives you full control over the logic of your automations, allowing you to manipulate data in complex ways, implement specific algorithms or connect to external libraries. You can train AI models within your flows or process information using frameworks such as TensorFlow or PyTorch, expanding the capabilities of your intelligent agents.

Practical use cases with n8n and AI

Practical applications of n8n with AI are changing how businesses manage their day-to-day operations. Here’s how to implement this combination in real-world scenarios to maximize efficiency.

n8n chatbot for real-time customer support

n8n’s integration with the Evolution API allows you to create intelligent chatbots that automatically respond to customer queries. These chatbots manage frequently asked questions, schedule appointments, and collect relevant information from users. Thanks to the flexibility of n8n, you can customize responses to your specific business needs.

A well-configured n8n chatbot can:

  • Reduce time spent on repetitive tasks
  • Provide 24/7 support without human intervention
