Master Typing in the Cosmos
"It's actually 10,000 iterations to mastery, not 10,000 hours. It's the number of iterations with error correction that drives the learning curve."
— Naval Ravikant
Doing the same thing over and over. Practicing errors until they become habits.
Each attempt includes error correction. Every keystroke analyzed, weak spots identified, targeted practice.
"Your hand is actually a remarkable thing. Look closely at your hands and think of all the things you can do with your hands."

Turn that remarkable instrument into a precision typing machine.
I've been typing for over 20 years as a developer. Thousands of hours at the keyboard. Millions of keystrokes.
But here's the uncomfortable truth I discovered: I was making the exact same mistakes for two decades. The angle brackets. The curly braces. The pipe character. Every time I needed them, my fingers hesitated, reached for the wrong key, or hit Shift when they shouldn't.
"Practice makes permanent, not perfect."
I wasn't getting better. I was reinforcing bad habits with every keystroke.
That's when I realized the difference between repetition and iteration. Naval Ravikant's insight about 10,000 iterations with error correction clicked. I wasn't iterating—I was just repeating my mistakes over and over.
So I built CosmicKeys—first for myself, to finally break two decades of bad habits.
A systematic approach to typing mastery based on iteration and error correction
Start with a quick typing test. No signup required. See your WPM, accuracy, and typing rhythm instantly.
Every keystroke is analyzed. We identify which keys slow you down, which fingers need work, and your unique error patterns.
Practice exercises tailored to YOUR weak spots. Not generic drills—targeted training based on your actual typing data.
Track your progress over time. See WPM and accuracy improve as proper technique becomes muscle memory.
Animated hand guides show exactly which finger should press each key
Audio guides talk you through lessons in multiple languages
Practice with YOUR text—emails, code, documents you actually type
No signup required. See your results instantly.
We respect our competitors, but we built CosmicKeys to solve the problems they couldn't. See the honest comparison.
