@kote2I share practical examples and ideas for AI automation using tools like n8n, explained in a way that’s easy for beginners to understand. While Dify is currently more well-known in Japan, n8n complements it and is expected to gain even more attention in the future. This channel aims to be a practical guide you can rely on when that wave of popularity arrives. That said, I’m still learning too—so let’s learn and grow together!
