Text-based PDFs (not scans). Add one or several at once — all are kept in your library below. Two-column charts — lyrics on one side, chords on the other — are detected and preserved.
This is the key your chart is written in. Correct it if the detection is off.
All twelve keys are selected by default, including your original. Tap to toggle any off.
Preview any key and check the chord map. Nothing but the chords and the chart's own key label changes — lyrics, tempo, theme, and the vocalist's reference key stay put.
Editable .docx in your original two-column format. Open in Word (or Google Docs / Pages) to make any amendments.
