Musire

Musire is a collection of free guitar tools that run in the browser and are designed mainly for phones. It is aimed at casual players who want to tune up, look up a chord or play along without creating an account or installing an app.

The basics cover a microphone-based tuner, a metronome with tap tempo, a chord library where every shape can be played back, a chord transposer and capo chart, an interactive fretboard, and a song sheet that keeps chords above the lyrics while it scrolls. The play-along side is where it differs from a plain tool collection: Band DJ lets you line up chords and pick a style so a virtual band (guitar, bass and drums) plays them in any key, while Lead Guitar, Chord Harp and Play Pad let you slide, bend and solo over that band. There are also power chord and bass guitar trainers, a practice routine builder with streaks, and a beta tab transcriber that turns a short guitar recording into tab.

Settings are stored only on the device and microphone audio is processed locally. Musire can be added to the home screen as a progressive web app and works offline after the first visit. It is free and supported by ads and affiliate gear links.
