AI-powered — add a topic and generate in under a minute.
Build a Problem-Solving Simulator on any design topic — scaling a web service, a data pipeline, a CI/CD flow, networking. Enter a topic and the AI generates a scenario with a component palette; you drag the right pieces onto a canvas and connect them into a working solution, testing design skill rather than recall.
Want a knowledge check instead? Try a multiple choice quiz or a fill-in-the-blanks quiz.
It is an interactive challenge where you are given a real-world scenario and a palette of components, and you build the solution on a visual canvas — dragging in the right components and connecting them into a correct flow. It tests whether you can design a system, not just recall facts.
Server-side, on two things: did you place the right components (and avoid the decoys), and did you wire the correct connections in the right direction. You get a 0–100 score and a sober proficiency label, plus the reference design with a reason for every connection.
Yes — creating a simulator is free on the starter plan. No credit card required.
