Quick context: KeepSimple's UX Core is a free open-source library of cognitive biases used by anyone designing or shipping things to real users.

Until now, each bias had a definition and use cases. Reading is one thing, but seeing the bias in action is what makes it stick.

So we added a visual example inside every bias modal. Open any bias, scroll down, and you'll see how that specific bias can be used in product design to drive efficiency, improve conversion, reduce friction, or guide user attention where it matters.

This makes the library actually usable in the moment.

Try it here on Attentional Bias, for instance:
