Why Pro is worth it
The €199/year isn't for a PDF of free content. It's for Prova running on your own data, the entire continuously-updated curriculum, verifiable certificates, saved work, higher compute — and every book, living.
Less than the big subscription platforms charge for a fixed course library — and Pro runs on your own data.
Frequently asked questions
- Is the book really free to read?
- Yes. Every chapter is a free, runnable lesson online — the complete book, no paywall on understanding. Pro adds the offline typeset PDF/ePub, Prova on your own data, certificates, and more.
- Can I buy just this one book?
- The offline PDF is a Pro perk, not sold on its own. If you want a single-book, one-time purchase, the ebook is available on Kindle. Everything else lives in Pro.
- What formats does the Pro book come in?
- A typeset PDF at launch, with ePub as a fast-follow — both watermarked to your account and auto-updated from the same source as the free lessons.
- Do the books keep getting updated?
- Yes. Each book is generated from the living lessons, so your offline copy tracks the latest edition — no frozen, out-of-date PDF.
- I bought this book before — what happens to my purchase?
- Your past purchase and Kindle copy stay yours. Pro is a new, recurring option that adds the living online book plus the whole platform.
