Your Brain on AI

How the Same Tool Sharpens Some Minds and Dulls Others and the Simple Habits That Make the Difference

Are You Using AI to Think Better – or to Think For You?
Artificial intelligence is quietly creating a cognitive divide.
Some people are becoming sharper, faster, and more mentally agile than ever before.
Others are experiencing subtle mental atrophy—shorter attention spans, weaker memory, and growing dependence on digital tools.

The difference is not the technology. It’s how you use it.

In Your Brain on AI, veteran creator and lifelong cognitive trainer Jimmy Lockett reveals the hidden mechanisms that determine whether AI strengthens your mind or slowly dulls it—and shows you how to stay firmly on the sharp side of the divide. Drawing on neuroscience, real-world research, and decades of high-level mental performance, this book introduces a powerful shift:

Stop using AI as a crutch. Start using it as a cognitive training partner.

Inside, you’ll discover:
• Why passive AI use can quietly reduce critical thinking, memory, and focus
• The Crutch vs. Colleague model that explains why the same tool produces opposite results
• The four invisible mechanisms that either build or steal cognitive strength
• Simple “prompt shifts” that turn everyday AI use into a mental workout
• A practical framework for improving attention, processing speed, memory, language, and executive control
• The 7-Day AI-Proof Brain Challenge—designed to fit into the AI use you already have
• A clear, sustainable path to sharper thinking without adding time, apps, or routines

This is not a book about avoiding AI. It’s about using it intelligently - so your brain stays active, resilient, and in control.
Whether you’re a professional, creator, student, or lifelong learner, Your Brain on AI shows you how to turn today’s most powerful tool into a force for long-term cognitive strength instead of quiet mental decline.

The tool isn’t the threat.
Passive use is.
And the solution is simpler than you think.
