Build from scratch
Design your own system, and have the AI check it
A blank canvas and every AWS service. Describe the system you want in your own words, draw it, and the AI tells you whether the design does what you described — what is missing, what is wasted, and what to fix next.
Building from scratch comes with a plan
So does every scenario, the AI review of each answer, and the shape library — 5 AI checks a day.
An AI review of your answersDesigns you build from scratch, multiple-choice picks and filled-in gaps, each reviewed against the scenario and the choices you actually made. Up to 5 new reviews a day; a design that has been reviewed before comes back without using one.
Why it works, or why it doesn’tWhether your design meets what the scenario asks, and what in it is wasteful.
What’s needed, and what isn’tEach missing piece named with the reason the scenario needs it, and each extra with what it costs you.
Where you’re laggingA scored breakdown of every service and connection, and the one thing to fix next.
A check of designs of your ownDescribe a system in your own words, draw it, and the AI says whether the drawing does what you described. No score, because nobody wrote an answer key for it. It shares the daily allowance.
New scenarios, written for you10 a month: a brief nobody has answered before, on a shape you have not practised yet, built from scratch and marked by the same scorer as the rest. Its own allowance, separate from the daily reviews.
Every scenario, three ways to answerBuild from scratch, pick from multiple choice, or fill the gaps in a reference design.
The shape library16 architectures, the signals in a brief that point at each, and what each costs you.
