Where to start
Pick your way in.
The archipelago
Five islands, one path.
Each island has its own world, challenges, and end-of-chapter projects. The first chapter of each one is playable right now. The next ones are on their way, free as well.
The method
How it works
You play each chapter in one short session. Same three stages every time, so your effort goes where it counts.
01
Understand
One screen, one idea. Diagrams and concrete examples instead of walls of text, so you get how it works before you use it.
02
Play
Pick answers, match pairs, fix prompts, make code pass, put steps back in order. You try things, make mistakes safely, and it sticks.
03
Ship
Every chapter ends with a real project, complete with a brief and a checklist. You walk away with something useful, not just a score.

Frequently asked questions
Before you set sail
The easiest way to get a feel for it? Play the one-minute lesson at the top of the page.
Do I need technical knowledge?
No. Lantern and Prism islands start from scratch. Forge island, on AI-assisted coding, is for motivated beginners: you progress through tiny challenges, right in your browser.
Which tools are covered?
The major assistants (ChatGPT, Claude, Gemini, Grok, Mistral's Le Chat…), image and video generators, AI code editors and automation tools. The method is designed to keep working as the tools change.
Do I have to pay for AI tool subscriptions?
No. You play the chapters here, in your browser. To practice with the real tools afterward, their free plans are enough to learn on, with some limits. No subscription is required to follow the course.
Is Ovrelia really free?
Yes. Everything published on Ovrelia is free: chapters, games, blog and news. No account, no ads, nothing to pay.
Why can't I play some chapters yet?
They're still being written. On the map they show “Coming soon, free”: they will open for free, just like the first chapter of every island.
Can I follow it on my phone, and in which languages?
Yes. Everything runs in your web browser, on a phone, tablet or computer, with nothing to install. The course is available in English, French and Spanish: pick your language from the language menu at the top of the page.
How long does it take?
Plan on about 15 to 20 hours for the whole course, at your own pace. Each chapter takes one short session of roughly 20 to 40 minutes.
Where is my progress saved?
Only in your browser (localStorage): nickname, XP, streak, badges. No account, no server, no tracking cookie.
Is the content kept up to date?
Yes. Tools move fast, so chapters get revised when a method changes significantly. Updates stay free.
