The fretboard, visualised

Fretly is an interactive fretboard for guitarists who want the full overview: every scale, mode, chord type and voicing, in the keys and tunings you actually play. Precise enough to teach from, fast enough to noodle on.

What Fretly does

Look anything up, fast

Any scale, mode, chord type or voicing, drawn on the neck in seconds. Full board or position by position: CAGED, 3NPS, per-string.

See how it fits together

Circle of fifths, intervals, formulas and relationships, shown where they land on the frets instead of floating on paper.

Build your own practice library

Save boards into suites and collections, build diagram sheets, and keep clean tab and charts for practice or students.
