David Gewirtz [ZDNET] can't tell you if this one's worth it or not, since the course starts next week, but if you sign up and it's a waste of your time you've only lost a few minutes.
The course is called "Google AI Tools for Journalists: Optimizing Editorial Workflow, Content Creation, and Audience Engagement." It's obviously intended for journalists, but it could also be valuable to bloggers, influencers, teachers, students, YouTubers, or any other communicator.
The course is under the auspices of the Knight Center for Journalism, a project of the University of Texas at Austin. Knight Center provides free or low-cost online training programs in a variety of languages to journalists worldwide. That said, you don't have to be a journalist to take this course.
