Questions & Answers

As answered by people managing Diffee and CognitiveDrill.

Who are some of the biggest customers of your product?

CognitiveDrill's answer:

(Note: Since CognitiveDrill is a free, sign-in-free web platform for general users, you can list the primary user segments instead)

Competitive esports players and gamers tracking reaction speed

Students and professionals benchmarking memory and typing performance

Self-quantifiers and productivity enthusiasts tracking daily cognitive performance

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.

Why should a person choose your product over its competitors?

CognitiveDrill's answer:

Unlike platforms that charge subscriptions or make exaggerated claims about increasing intelligence, CognitiveDrill is 100% free, requires zero sign-in, and offers over 40 fast, sub-two-minute laboratory tests focused purely on accurate benchmarking and personal tracking.

How would you describe the primary audience of your product?

CognitiveDrill's answer:

Gamers, student athletes, developers, productivity enthusiasts, and anyone looking to track baseline cognitive metrics—such as reaction time, digit span, and processing speed—using precise, no-nonsense tests.

What's the story behind your product?

CognitiveDrill's answer:

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.
