Developers sometimes struggle to identify UX problems in their own work. The problem is becoming more pressing as coding agents take on more of the implementation work, but fail to address usability issues.
A long time ago, I stumbled upon Can't Unsee, an in-browser design problem detection game. I found it was a fun way to improve my design skills. I imagined a similar game for UX, where user interaction is key, to help train my colleagues. However, building such a game proved difficult at the time.
This changed with AI coding tools and transformers. Not only did the cost of building mini-apps rapidly decrease, but scoring user answers became feasible with an in-browser ML model.
So here it is : a UX problem detection training game. Users examine mini-applications, identify the deliberate UX flaw in each, and describe it in text. Best of all: it's open-source, so anyone can add new mini-apps.
