Course Description

Agentic AI does not have to be complex or intimidating.

This beginner-friendly course introduces Agentic AI using n8n in a simple, practical, and easy-to-follow way. This course helps you understand the core ideas behind AI agents by building small, understandable workflows step by step.

The goal of this course is to help you learn how to think in terms of agents and workflows, not just prompts.

You will start by creating a very simple AI agent and gradually add important concepts such as tool usage, basic retrieval (RAG), human approval flows, quality checks, and safety rules, all using n8n’s visual workflow builder. The examples are intentionally kept small and beginner-friendly.

No coding, complex math, or deep AI theory is required.

⸻

What You Will Build

Throughout the course, you will build focused beginner-level examples, including:

• A simple AI agent that responds to task assigned by using the provided tools through MCP

• A basic HR Policy agent that uses Agentic RAG to answer employee queries

• A Clinical Assistant that helps doctors to automatically pick a specialist ,draft and sent a recommendation email

• A Human-in-the-Loop that sends the mail only after human approval

• Simple evaluation workflows to score AI responses for clarity and correctness

• Basic guardrails to block unsafe or sensitive outputs and route them for human review

Each example is designed to introduce one new concept at a time.

⸻

What You Will Learn

By the end of this course, you will be able to:

• Understand what Agentic AI means in simple terms

• Understand the difference between chatbots and agents

• Build your first AI agents using n8n

• Use tools such as Google Drive, Google Sheets, and Email inside agent workflows

• Understand the basics of Retrieval-Augmented Generation (RAG)

Excellent course! Great activities, straight to the point, and the exercises reinforce what you’ve learned very effectively.

By Jainal Shaikh on 7/23/2026

It is definitely a good beginner course. The content is good and concise. Use cases are good and can be related to many known sectors. Trainer is good. Sometimes there were voice loss and technical glitch in the recording.

By Asuтosн Hota on 7/15/2026

I recently completed the "Agentic AI for Beginners: Build No-Code AI Agents with n8n" course, and it was a great learning experience. The course explains the fundamentals of AI agents in a simple and beginner-friendly way. I especially liked the hands-on approach to building multi-agent workflows, integrating LLMs, and automating real-world tasks using n8n. The explanations were clear, and the practical examples made the concepts easy to understand and apply. I would recommend this course to anyone who wants to start learning Agentic AI and no-code automation.

Great agentic AI course using N8N for beginners. Understood the main concepts of Agentic AI with hands on practical sessions

By Anindita Deb chowdhury on 6/1/2026

The course is informative and delivers valuable knowledge within a short timeframe. The resources and use-case examples provided are helpful, clear, and easy to follow. One area that could benefit from further elaboration is the implementation of HITL (Human-in-the-Loop), Guardrails, and Evaluation workflow. In particular, the handling of False/Fail scenarios could be demonstrated in greater detail. For example, in the HITL section, it would be beneficial to include a practical workflow showing how the process loops back when a human reviewer rejects the generated output. A step-by-step example where the email subject and body are regenerated after a rejection would help beginners better understand how to design iterative approval workflows using the IF node's False path. Similarly, for the Guardrails section, providing sample fail-case scenarios and demonstrating how the workflow should respond when validation fails would make the concepts easier to grasp. Including a practical example of the Sanitize Text node and explaining how it handles problematic inputs would also add significant value. Overall, the course is well-structured, concise and worthwhile. Expanding the coverage of False/Fail paths with a few end-to-end examples would make it even more comprehensive and help learners gain a clearer understanding of real-world workflow implementations.

One of best learning I did. Great session, Great speaker, Great organization and complete balance of knowledge, practice and theory. Great Job Bharath. I would like to see more of your training on this AI. How to reach out to you? My no is 7042653969

By Anjaneya Ravi Prasad Kambala on 4/16/2026

very clear detailed explanation, easy to understand, curiously waiting for practical session to get hands on experience.

By Sudarsana Gudipati on 3/7/2026

This course is a perfect, as the title aptly says, a beginner no-code n8n course. Use it for conceptual understanding of how Agents and Agentic AI works with a bite sized lessons and super practical hands-on examples. Assignments helped me to reinforce my learning. Thanks Bharat for a great introductory course that you put together. Looking forward a series of n8n courses to take the mastery to next level.

By Josiah Adetayo on 3/4/2026

The instructor is knowledgeable in the field. The examples used drives home the point. A real breakdown of the concepts are given which facilitate learning

By Anonymized User on 2/12/2026

The explanation of MCP was not presented in a way that supports beginners. It appeared to assume that the student was already familiar with the terminology and foundational concepts. For learners who are new to the topic, it would be more effective to start with simple language, clear definitions, and basic examples before introducing technical terms.
