Keystroke Cartographer

Type each target line accurately. A keyboard heatmap glows red on the keys you fumble and cools to blue as you improve. Every new drill is generated to attack your hottest keys, and the run ends when the whole map is charted, every key mastered.

• Type the target line; it only advances on the correct key
• Watch the heatmap mark your weak keys in real time
• Each drill regenerates to target the keys you keep missing
• Master every key to chart the full map and finish the run

• Desktop: just start typing; Backspace steps back a character
• Phone & tablet: a physical keyboard is recommended, this drill is built around real key presses

• Prioritise accuracy over raw speed, clean keystrokes cool the map faster than rushing
• Don't fight the cursor; let your fingers find a rhythm on the hard keys it keeps serving you
• Daily gives everyone the same drill seed; Practice resets a fresh map any time

Keystroke Cartographer is an adaptive typing trainer that maps and targets your weakest keys, so practice goes exactly where it's needed.

• Skills: touch typing, keyboard fluency, accuracy, weak-key practice
• Best for: roughly grades 3–12 (ages 8+)
• For parents & teachers: targets the exact keys a typist struggles with.

A heatmap glowing red on the keys you fumble, with each new drill generated to attack your hottest keys, is adaptive practice applied to touch typing.

Generating the exercise from your own error profile is the original mechanism.

Typing errors are highly individual and highly persistent — most people have a handful of specific keys and digraphs they reliably miss. Generic drills spend most of their characters on keys you already own, which is why targeted practice improves accuracy far faster than volume does.
