THE METHOD / 01
Know what goesinto your result.
Selected letters are drawn with a seeded generator into five-letter groups. Historical errors count mismatched final letter positions.
Keep the assumptions clear
This is a synthetic letter drill, not an AI-generated story. Only A–Z keys are accepted. No key events are observed outside the typing control.
A FEW USEFUL ANSWERS
Good to know.
Are my inputs uploaded?
No. Calculations run locally in your browser. The host still receives normal requests for website pages and assets.
Can I keep my result?
Use the download controls for the current tool or print from your browser. Typing scores and camping plans can also be saved locally; see the privacy page for details.
Do I need an account?
No sign-up, paid API or subscription is required. Both language versions use the same calculation logic.
