AI Ready, together.

A student-led AI club at Los Osos High School. The curriculum started as Saturday classes at our kitchen table — and is now open to every Grizzly, whether you're excited about AI or worried about it.

From a kitchen table to a school club

Leo (a dad in Rancho Cucamonga) has worked in telecom and IT for years — and uses AI tools at work every day. He was already convinced AI was going to change a lot, and had started teaching his son Ethan on the side. At a get-together, Hannah's dad heard about it and asked, "Could you teach the kids?" That's how the Saturday class started. Three students show up at the kitchen table: Ethan, his classmate Hannah, and Hannah's younger brother Rainier.

After a few weekends, Ethan brought something back from school. Some of his classmates were worried about AI — they'd heard it was going to take jobs, change careers, mess things up before they could even graduate. Other classmates wanted to learn it, but had no idea where to start. Either way, nobody was really talking about it.

When Ethan started 10th grade, he went looking for clubs to join. Leo suggested an AI-related one — but Los Osos didn't have any. So Ethan asked his school counselor about it, and she suggested something different: why not start one yourself? So he did. This site is the curriculum that comes with it — the same one we use at home, opened up to every Grizzly who wants in.

What "AI Ready" means to us

Two kinds of students join a club like this. Some are excited about AI and want to know what's under the hood. Others are nervous — worried AI will take their future job, replace their major, or change everything before they're ready. Both groups belong here.

Both groups also get the same thing from the curriculum: a chance to understand AI from the inside, instead of just from the news cycle. The way you stop being afraid of a thing is to understand it well enough to make your own call about it.

Once you've built a small AI agent of your own — given it memory, taught it a skill, watched it succeed and fail at real tasks — you have a much better sense of what AI actually does and doesn't do. That's what "AI Ready" means to us. Not "use AI for shortcuts." Not "fear AI from afar." Just: understand it well enough to drive instead of being driven.

What you can do here

Five buckets, in roughly the order you might use them.

Adventures
Multi-lesson paths. Adventure I (Build Your AI Agent) is live — 8 lessons, end-to-end. Adventure II (Inside the LLM) is live too — all 6 weeks shipped, deck + quiz on each.
Workshops
Single-session focused decks. "How to Build a Website" is live — 3 hours from inspecting a real site to deploying your own.
Sandboxes
Tiny hand-built sites you can fork and remix. Read the code, change one line, watch what changes. The fastest way to actually learn.
Quizzes
90 questions across 9 quizzes. Pass at 80%+. Retake as many times as you want — the goal is for you to really get it, not to get it on the first try.
Optional account
Sign in with email or Google to save progress across devices and earn XP. Minimum personal info, one-click delete, no advertising or tracking. Or stay signed out — everything still works.

For the Grizzlies

Whether you've never written a line of code or you've been programming for years — there's a path through this for you. Adventure I starts at "what is a cloud server," and the workshops are tighter standalone topics you can drop into.

You don't need a fancy laptop or any subscription. A Chromebook and a free GitHub + Cloudflare account is enough for the full curriculum.

Move at your own pace. Retake quizzes until you really get it. When you get stuck — and you will — ask the club. That's why it's a club.

From the family

A note from Leo & Ethan

We're Leo and Ethan — a dad and son in Rancho Cucamonga. The lessons on this site are the same ones we still work through on Saturday mornings at our kitchen table, with Ethan's classmate Hannah and her younger brother Rainier.

We're donating ai.ethanxi.com to the Grizzly AI Club at Los Osos High School. The domain, the lessons, the quizzes, the server bills — all of it. From here on, the club owns it.

Ethan will help run the club. Leo will keep paying the server bills and answer technical questions when needed. The rest is up to you, Grizzlies. We hope you make something great with it.

The honest goal

To open one more path through the woods — a path where you build the thing instead of just hearing about it.

If you finish more curious about AI than when you started, and you can make something that wasn't there before, this did its job.
