This video is a comprehensive masterclass on n8n, a low-code/no-code automation tool. It guides viewers from beginner to advanced levels, focusing on building AI agents and automating workflows. The video covers setting up n8n, understanding core concepts (workflows, nodes, executions), integrating with AI services (RAG, vector databases), utilizing APIs and HTTP requests, and implementing best practices for error handling and workflow optimization.
n8n Introduction: n8n is a user-friendly, low-code/no-code automation tool enabling users to build workflows with minimal coding. It offers a drag-and-drop interface and numerous integrations.
Self-Hosted vs. Cloud: The video details the advantages and disadvantages of self-hosting versus cloud hosting n8n, guiding users to choose the best option based on their technical skills and data security needs.
Core Concepts: The video explains the fundamental components of n8n workflows: triggers, actions, data transformations, and logic nodes, illustrating how they work together to automate tasks.
AI Agent Building: The tutorial demonstrates building an AI agent using RAG (Retrieval Augmented Generation) and a vector database (Pinecone). This involves embedding data from a PDF into the database and creating an n8n workflow that allows users to interact with the document via a conversational AI agent.
APIs and HTTP Requests: The video explains APIs and HTTP requests, showing how to use them in n8n to connect to services lacking built-in integrations. Examples include fetching weather data and interacting with a Google Calendar API.
Error Handling and Best Practices: The video covers creating error workflows to handle issues in n8n, along with best practices for workflow organization, reusability (sub-workflows), and scalability.
