Progressive lessons for QWERTY, Dvorak & Colemak. Real-time stats, a virtual keyboard with finger hints, and session history — in a fast, lightweight binary built with Rust and ratatui.

clavirio — from Latin clavis (key).

Features

  • 15 built-in lessons — progressive drills from home row to full paragraphs and code; lessons 1–9 are layout-specific, 10–15 are shared
  • Random words — practice with the 200 or 1000 most common English words
  • Timed mode — 30s and 60s countdown sessions with random words
  • Live stats — WPM, accuracy, errors, time, and line progress in a one-row status bar
  • WPM sparkline — see your speed over time on the results screen
  • 3 keyboard layouts — QWERTY, Dvorak, and Colemak
  • Virtual keyboard — highlights the next key with finger hints (Pinky, Ring, Middle, Index, Thumb)
  • Error feedback — wrong keystrokes shown inline, blocked until corrected with Backspace
  • Session history — saved to ~/.clavirio/history.json with per-lesson tracking and averages
  • Progress tracking — remembers your last lesson; advances automatically on completion
  • Custom text — load any file via Ctrl-F or as a CLI argument
  • CLI flags — start modes directly from the command line
  • Dark & light themes

Lessons

Lessons 1–9 are layout-specific (each layout has its own drills matched to that layout's finger positions). Lessons 10–15 are shared across all layouts.
