Common questions
What will I build in Advanced AI Engineering?
Engineer-grade depth: how LLMs work, evals, agents, and production AI. You start in lesson 1 and build up across 30 free, bite-size lessons — everything you make is real and yours to keep.
Is bloom0 free?
Yes — all 110 lessons are free forever, with no paywall and no sign-up needed to start. If it clicks for you, there's an optional one-time $1 to support the project, but it never blocks a lesson.
Do I need coding or tech experience?
No. bloom0 is built for total beginners. You learn to build with AI in plain language — the first lessons assume you have never written a line of code.
Do I need to sign up or install anything?
No. It runs in your browser and you can start lesson 1 right away — no account, no download. Creating a free account is optional and just syncs your progress across devices.
Is bloom0 available in Spanish?
Yes. Everything is fully bilingual — every lesson, quiz, cheat sheet, and the AI coach work in both English and Spanish. Switch languages anytime with one tap.
