About

A guitar tutor
that listens.

Lark is a free guitar tutor that runs in your browser. It hears the notes you play through your microphone, scores each one in real time, and coaches you when you finish a song.

01The product

What Lark does

  • A tuner and a chord detector that work without an account
  • 83 songs on a scrolling tab, with every note you play scored live
  • Practice Mode: slow a song to 0.5x or 0.75x and loop any section
  • A six-stage learning path, from first sounds to lead playing
  • An AI coach that reviews each run and gives you one concrete tip
  • Over 120 chord diagrams, a metronome, and daily missions with XP

All audio processing happens in your browser. Lark never records, uploads, or stores what you play.
