“The videos were very helpful and filled in gaps in what I didn’t already know. They weren’t too long, the pacing was spot on, and I gained a lot of useful knowledge from the course.”

Meet Leslie Tennie.

Leslie Tennie is the founder of Calm Money OS™, an AI educator, entrepreneur, and digital product strategist who helps beginners, creators, and business owners understand how to use artificial intelligence with clarity and purpose.

Her teaching focuses on making AI practical, approachable, and easier to apply to real ideas, real businesses, and real income opportunities.

She does not teach AI to make people feel impressed by complicated technology. She teaches it so people can finally say:

“Oh. I understand this—and I know what to do next.”

Confidence starts with understanding.
