It was a lecture series consisting of a total of 28 lessons, and I was truly surprised because the instructor went beyond simple function explanations, meticulously pointing out even hidden buttons and features that aren't taught anywhere else. The more I listened to the lessons, exclamations like "There was a feature like this?" and "I can use this in such a way?" kept coming out, and I was newly reminded that Felo AI is a much more powerful tool than I had thought. It's not a course that ends with a single viewing, but one I definitely want to review again to properly master. Thanks to the instructor's deep understanding and delivery skills, even content I was encountering for the first time was easy to approach, and since it contained tips that could be applied in real-world situations beyond simple practice, learning efficiency was very high. Frankly, if you were someone who only vaguely knew about Felo AI, just by properly taking this one lecture, your mind will be filled with ideas useful for practical work.
