Who built this course, and why

Arnaud Caillot

Growth product manager with 15+ years building and scaling digital products. I write every module here from workflows I actually run - research synthesis, experiment design, automations, agents and prototypes - not from press releases.

Why this exists

Most AI training is either an inspirational keynote or a tool demo. Neither changes how you work on Monday. This course is the opposite: 11 modules, each with a lesson, copy-ready prompts, a hands-on exercise and a quiz - built for product, growth, design and engineering people who need leverage rather than theory.

How the content is built

• • Every prompt and workflow has been used on real product work before it ships here.
• • Lessons talk about capability tiers rather than model version numbers, so guidance survives releases.
• • Tool recommendations name the job to be done first and the product second.
• • Nothing is sponsored: no affiliate links, no paid placements, no vendor review.

How it is kept current

AI moves fast, so the material is revised on a rolling basis and every change is logged publicly. Last content review: August 2026. Read the changelog.

What it costs

Nothing. The course, the prompt library, the glossary and the certificate are free. You will need access to at least one AI assistant; a free tier is enough for most modules.
