Built for every player

Lefty mode on every fretboard tool.

Most online guitar tools assume you play right-handed. Every Guitar Lick Lab fretboard tool includes a one-tap mirror mode — nut on the right, frets ascending to the left — so left-handed players see the neck the way they actually see it. No more mental flipping.

Live on every fretboard-based tool — six tools as of v2.8
01 / Guitar Learning Tools

Practice, theory, fretboard, and soloing.

Use these tools to build speed, understand chords and scales, map ideas on the fretboard, and connect theory to real guitar playing.

What Chord Is This?

Interval Ear Trainer

Hit play to hear two notes — name the interval. Six difficulty presets from beginner (Perfect 4ths, 5ths, M3s, octaves) through advanced (all 13 intervals). Ascending, descending, and harmonic modes. Streak tracking and shareable preset URLs make it easy to drop preset drills straight into a YouTube video description.

Capo Key Converter

Place a capo on any fret and instantly see what key your familiar chord shapes actually sound in — plus the reverse: given a target key, see every capo position that turns your shapes into the right key, sorted by playability. Includes chord diagrams for all eight CAGED open shapes.

Browser-Based Guitar Tuner

Tune any string straight from the browser using your mic — clean visual feedback, standard plus 14 alternate tunings (drop D, half-step down, DADGAD, open G, open D and more) including dedicated 7-string and 8-string presets. No app install, no detours from your practice.

Pentatonic Box Finder

Visualize all 5 box positions of any minor or major pentatonic scale on the fretboard. Flip on Show Triads to see the chord shapes hidden inside each box — both the i (minor) and ♭III (relative major) triads, every inversion, every playable shape on adjacent strings.
