Hello,

I'm a teacher with 12 years of experience, and I want to offer your child the opportunity to learn about something that will shape their future: artificial intelligence (AI). It's not just a topic of the distant future; AI is already here, and learning about it can give them a huge advantage in their education and, later, in their career.

I've been working with AI in my own companies for years and have extensive training, taking specialized courses and earning a master's degree in this field. My goal is for high school students, ages 12 and up, to understand how AI works and, most importantly, how they can leverage it. It's not about memorizing complicated concepts, but rather learning how to use tools that are already changing the world.

In the private lessons I offer, your child will learn how to use apps like ChatGPT, Copilot, Runway, and many more. We'll cover how to automate tasks, create video, photo, and audio content, and improve productivity. All of this is done in a practical and fun way, so that each lesson is a truly enjoyable experience that motivates them to continue exploring.

Additionally, each class is fully tailored and personalized to each student's needs. I ensure the content is accessible and relevant to each student, so they can progress at their own pace and get the most out of what they learn.

If you're looking for private lessons that really make a difference, I'd be happy to guide your child on this exciting journey into the future...today!

Let's talk and organize the classes!
