Google Opal Practical Course | Creating a Workflow to Automatically Generate Blogs, Thumbnails, and SNS Posts from Audio

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.

CEO of Deep Sea Inc. After graduating from Waseda University, I spent 16 years building a career as an HR expert (specializing in recruitment, talent development, and organizational development) at a global foreign-affiliated company operating in over 220 countries. I have been extensively involved in establishing human resource strategies that support corporate growth.

While living in the United States, I experienced firsthand the innovation brought by generative AI and its overwhelming impact on operational efficiency. After returning to Japan, I founded DeepSea Inc. and have since been dedicated to developing and delivering online courses that teach AI skills ready for immediate application in business settings.

My courses are designed to help busy business professionals acquire **"practical skills that deliver results in a short amount of time."** Rather than cramming in difficult theories, I emphasize templates that can be used immediately in the workplace and highly reproducible know-how. These courses can also be implemented as corporate training programs.

As the author of books such as "ChatGPT x Audio Broadcasting" and "100 AI Time-Saving Techniques for Moms," my mission is to explain how to utilize AI technology in daily life and business in an easy-to-understand way. I look forward to delivering practical knowledge on improving productivity through AI to our learners in South Korea.
