Chordpeek

Turn live guitar chords into an offline songboard with key analysis, roman numerals, transposition, rehearsal timing, tuner, and chord library.

Chordpeek is a private guitar workstation that recognizes live chords, turns ideas into structured charts, and keeps the tools you need to rehearse in one focused app.

SONGBOARD STUDIO Build a complete chord chart from live detections or manual entry. Organize chords into song sections, set beats and tempo, infer the likely key, see roman numerals, transpose the whole chart, rehearse against a synchronized metronome, and share a clean plain-text chart. Songboards are saved locally and remain editable.

LIVE CHORD ANALYSIS Play near your device and see the detected chord, confidence, heard notes, fingering, matching keys, harmonic function, and roman-numeral role in real time.

TUNE AND PRACTICE Use the precision chromatic guitar tuner, configurable metronome, ear-training sessions, practice timer, streak history, and strumming-pattern library.

OFFLINE MUSIC REFERENCE Browse and bookmark the built-in chord library, inspect string-by-string fingerings, explore scales and modes, compare related keys, study common progressions, transpose progressions, and calculate capo positions.

PRIVATE BY DESIGN No account, subscription, advertising, analytics, or server is required. Microphone audio is analyzed on device and is never recorded, stored, transmitted, or uploaded. Songboards, favorites, and practice history stay on your device.
