A short film of kalibre being used: a sentence typed with one slip, circled; the mistakes screen with the t and h keys marked as swapped; a drill built from those slips; a lesson with Cal; the games menu with seven games playing; and the same screen in other themes.
an adaptive typing trainer that learns your recurring mistakes.
your typing.
your mistakes.
your progress.
notice
it notices what you keep getting wrong.
a wrong key, a missed shift, swapped letters, a missed space, a real word for another real word. kalibre records every slip, and where it sits on the keyboard. it notes the keys you hesitate on, too.
train
then it turns them into drills.
a mistake is only suggested once it repeats: enough times, across enough sessions. accept it and kalibre builds practice around it, then follows it from training to improving to mastered as your error rate falls.
learn
touch typing, with company.
lessons that grow one finger at a time, guided by Cal or Libby. pick who walks with you when you begin.
play
seven games. every one of them typing.
- feed feed a hungry creature the words it asks for before its patience runs out, or run a buffet for a crowd.
- castle build your walls out of words and hold the line until the attackers give up.
- space steer with the mouse, fire with words, and keep the ship alive.
- spot find the mistakes planted in a passage and put them right.
- marathon proofread a whole book against the clock: fixes buy time, mistakes cost it.
- scroller proofread a passage or a whole book as it scrolls up: fix each mistake before its line leaves the top.
- race race the computer on your own, or people on your network, in a quote, words, against the clock or for as long as you keep up.
