What makes your product unique?

CognitiveDrill's answer

CognitiveDrill focuses strictly on honest, precision measurement rather than inflated brain-training claims. It starts timing the millisecond a stimulus renders on the screen, throws out cheap guesses (<100ms), uses median scoring to eliminate luck, and benchmarks results directly against real reference distributions.

It was built out of frustration with online brain-training tools that lock simple tests behind paywalls and market unproven claims about "brain age." CognitiveDrill was created as a lightweight, accessible alternative to deliver honest, accurate cognitive benchmarks directly in the browser.

Which are the primary technologies used for building your product?

CognitiveDrill's answer

Modern Web Stack (HTML5, CSS3, JavaScript/TypeScript), HTML5 Canvas API, and Web Audio API for precise millisecond-level stimulus rendering and timing.
