I used to spend hours writing blog posts myself. I wasn't good at writing; it would take me 30 minutes just to come up with a title and an hour to create a thumbnail. When I included the time spent thinking of social media posts, it sometimes took half a day just to complete a single article. Even though I was good at speaking, I struggled to organize those thoughts into writing. I enjoyed audio broadcasting, but the task of turning it into a blog felt like a chore, so I always put it off. However, everything changed once I started using Google Opal. Simply by uploading an audio file, the blog body, title, thumbnail, and social media posts are all automatically generated. What's more, by having it reference my own writing rules, it generates text that sounds like me and doesn't feel "AI-like." In this course, you will be able to build the exact workflow I use through the shortest possible route. No programming experience is required. You can build an AI app just by giving instructions in Japanese. It's okay even if you don't do audio broadcasting. You can complete an article just by speaking about blog ideas as they come to you. You no longer need to struggle for hours to write a piece. Just by speaking, your blog, thumbnail, and social media posts are completed. That future begins today.

Have you felt overwhelmed, not knowing where to start with AI automation? This course explains AI automation using Google Opal in a way that even non-majors can easily understand. Rather than difficult theories, we focus on practical automation examples to show you how to reduce repetitive tasks and increase productivity. This course is for those who want to turn AI from a "technology you've only heard about" into a "tool you use yourself."

"The deep learning code runs, but why do the formulas in papers look so unfamiliar?" As you study AI, you eventually hit a wall of mathematical formulas. If you trace the source of that wall, it usually leads back to not having a solid foundation in the most basic mathematical language. Starting with the language of sets, this course covers core concepts across 18 lectures, including equations, functions, sequences, exponents/logarithms, and trigonometric functions. We don't make you memorize formulas. While we briefly touch upon how these connect to the context of AI, the primary goal of this course is one thing — to build an unshakable foundation for when you later learn linear algebra, calculus, and probability/statistics. As the first part of the Suminjeongeum series, this course will provide you with the common language needed to properly digest the remaining three parts.

Statistics learned in school, was it too hard to understand? No matter how much you listened to the explanation, statistics were confusing, but we will help you understand them.

We will give you a gift. :)
