From Zero to Your First AI Agent in 25 Minutes (No Coding)

AI agents are autonomous systems that can reason, plan, and take actions using three core components: a brain (LLM), memory for context retention, and tools for external interactions. Unlike static automations that follow predefined steps, agents dynamically adapt and make decisions. The tutorial demonstrates building a practical trail running assistant using N8N's visual interface, connecting Google Calendar, weather APIs, Gmail, and custom HTTP requests without any coding. The agent checks schedules, analyzes weather conditions, recommends appropriate trails from a personal database, and sends customized email notifications.
