Everything below has shipped and works today. Most of it started
as a request from someone using the app — your feedback is the
roadmap.
⌨️ The typing
Human-paced typing engine
30–120 WPM, calibrated so the slider means what it says
Realistic mistakes — and corrections
Finger-anatomy slips, instant fixes, delayed fixes, the rare unnoticed one
Thinking pauses & punctuation rhythm
Long beats at periods, commas that breathe, warm-up and drift
Mouse glides
Curved pointer movement with natural timing and scatter
🌍 Works with your Mac
Your keyboard layout, natively
QWERTZ, AZERTY, Dvorak, Cyrillic — captured automatically at run start
Missed-Shift capitals & doubled words
Capitals land lowercase, "the the" — caught, or missed like a person would
Menu-bar mission control
Live progress, WPM and ETA; pause and resume mid-run
Safe by default
Auto-pause on password fields; Esc stops everything instantly
📬 Built from your feedback
The mistake model itself
Started as one email: "the typos look too random — people repeat
patterns"
Layout awareness
Requested by a Dvorak user on day one; shipped in v3.2
