N8n has established itself as a visual node-based workflow automation platform that connects different applications and services without the need for complex code. This tool differs from other options such as Zapier or Make because of its API-first approach and its flexible architecture that allows you to create custom processes using an intuitive drag-and-drop interface.
Differences between traditional and AI automation
Traditional automation executes only predefined sequences of actions, while n8n ai transforms these flows by providing them with intelligent capabilities:
- Traditional automation: Execute repetitive tasks following static and predefined rules.
- AI automation: Generates flows that automatically learn and adapt, analyzing incoming data to make dynamic decisions.
To illustrate this, an AI-powered flow can analyze emails using natural language models to detect urgencies or sentiments, prioritizing responses automatically and improving customer service efficiency. Companies that implement this type of automation experience a 30-40% increase in efficiency.
What is an n8n ai agent and how does it work?
An n8n ai agent is an autonomous system that uses language models (LLMs) to execute tasks without constant intervention. These agents function as a digital brain capable of reasoning, making decisions, and solving problems independently.
Here are the main components of each agent:
- A language model as a brain (OpenAI, Gemini, Anthropic, DeepSeek)
- Memory systems (short and long-term)
- Task planning and decomposition capabilities
- Integration with external tools via APIs
The “THINK” function empowers these agents, allowing them to analyze information, question results and decide their next steps accurately, functioning like a mental notepad.

N8n ai agents are changing the way businesses handle their day-to-day processes. Below, we will show you concrete examples of how you can apply them in your business.
Daily briefing assistant with Gmail and Google Calendar
This workflow acts as your personal digital secretary who prepares a complete summary of your day every morning. Here’s how it works: it automatically wakes up at 7:00 AM, pulls all your events from Google Calendar, analyzes external participants, and collects related recent email threads. The end result is a structured email with your daily agenda, relevant information about the attendees and context for each meeting.
Customer support with sentiment analysis and autoresponders
Imagine your inbox managing itself. n8n ai agents can continuously monitor your emails, analyze content using AI to classify messages according to urgency and sentiment, and generate personalized responses for each query. This process can reduce operational costs for repetitive tasks by up to 40%, allowing your team to focus on more complex interactions.
Smart scheduling with memory and availability validation
If you handle a lot of appointments, this specialized agent can automate the entire scheduling process. The system talks to the customer, requests the necessary information (name, email, type of service and desired date), checks the free spaces in your calendar and confirms the appointment by sending an automatic email. Remember that all this happens without your intervention.
Invoice automation with Gmail and Google Sheets
This 8-step flow completely eliminates manual invoice processing. Continuously monitor your Gmail for emails with specific labels, verify and extract PDF invoice data, analyze the information using AI to identify amounts, dates, and supplier details, and finally organize all this information in Google Sheets.
If you’re going to implement these workflows regularly, we recommend starting with simple use cases and then expanding the functionalities according to your needs.

Advanced AI Agent Capabilities on N8n

N8n ai agents stand out for their advanced technical capabilities that allow them to adapt to various business scenarios. These capabilities elevate your potential far beyond basic automations.
Memory Usage: Simple vs Persistent
Memory is critical for agents to maintain context in long conversations. N8n offers you two main options depending on your needs:
- Simple Memory: Stores a configurable number of recent interactions, but is volatile and clears when the system reboots or fails. It does not support queue mode and lacks semantic search.
- Persistent Memory: Solutions like Memara provide durable storage that survives reboots, works in queue mode, and offers advanced semantic search to find relevant memories by context.
Integration of external tools: SerpAPI, Slack, Notion
Agents in n8n can connect to external services by enhancing their capabilities:
Slack: Allows you to index conversations and public channels, facilitating contextual searches and generating automatic summaries.
Notion: Synchronize documents for queries and updates, being able to filter by specific spaces.
SerpAPI: Enables real-time web searches to get up-to-date information.
Using Code Nodes for Custom Logic
N8n incorporates nodes running JavaScript or Python to fully customize flows:
// Ejemplo: Concatenar textos con separación
const items = $input.all();
const textos = items.map(item => item.json.texto);
const resultado = textos.join(' ');
return {json: {textoUnido: resultado}};
These nodes allow you to manipulate complex data, implement specific algorithms, or connect to external libraries.
Multimodal inputs: text, images, and audio
Advanced agents in n8n process different types of input:
Step 1: Text – Analysis and generation of textual responses.
Step 2: Images – Conversion to base64 for analysis using GPT-4o vision capabilities.
Step 3: Audio – Automatic transcription to convert speech into actionable text.
This multimodal capability is essential for creating complete assistants that interact naturally with users.
MCP (Model Context Protocol) for tool reuse
The Model Context Protocol is an open standard that improves communication between agents and tools:
It allows tools to self-discover without custom code, transforms the problem of M×N integrations to an M+N sum, and since version 1.88, n8n includes native nodes such as “MCP Server Trigger” and “MCP Client Tool”.
This technology makes it easier for agents to access data and execute actions in real time without human intervention, taking advantage of tools such as log analysis, IP reputation verification or report generation.
N8n vs Relevance AI: Which one to choose for your AI agents?
When evaluating platforms for AI agents, focus and security should be key factors in your decision. We’ll show you the differences between two prominent options and the security measures you need to implement.
Key Differences Between Relevance AI and N8n
These platforms serve different needs in the automation ecosystem:
N8n focuses on workflow automation with a technical approach:
- Open-source solution with self-hosting and cloud options
- Node-based visual builder with over 350 integrations
- Greater privacy control through self-hosting
- Requires technical knowledge, especially for self-hosting
Relevance AI specializes in data analysis using AI:
- No-code platform for unstructured data analysis
- Clustering and sentiment analysis tools
- AI-powered automated reporting dashboards
- More accessible to non-technical users
We recommend n8n if you’re looking for overall automation and full control, while Relevance AI is better for AI-powered data analytics.
How to protect yourself from prompt injection
Prompt injection is an attack where hackers disguise malicious inputs as legitimate prompts to manipulate language models. This method, recognized as the #1 vulnerability in the OWASP Top 10 for LLM applications, does not require advanced technical knowledge.
N8n includes a defense workflow that:
- Detects threats, including injection attempts
- Clean markdown by removing dangerous HTML and protocols
- Validate URLs by blocking suspicious domains
- Generate security reports with risk assessment
5 Essential Security Measures for Your AI Agents
To protect your AI agents on n8n, follow these recommendations:
- Implement security barriers between the model and inputs/outputs using filters and validators
- Enforce least privileges, limiting agent access to only the data needed
- Use anchors to separate system instructions from user inputs
- Maintain human oversight to verify exits and authorize critical actions
- Set up telemetry logging to monitor suspicious inputs and outputs
Remember that these measures are not foolproof, but the right combination provides a solid defense against potential attacks while harnessing the power of AI agents.
