Frequently asked questions
Is my text sent to a server?
No. All text processing happens locally in your browser. Nothing is uploaded or stored.
Why is the Space key always the most used?
In most written text, spaces are the most frequent character. You can uncheck the "Space" filter to see the distribution without it.
What does hand balance tell me?
It shows the percentage of characters typed by each hand on a QWERTY layout. Balanced typing (close to 50/50) is generally easier on your hands.
