DomiSol vs Flat

DomiSol is a web-based score editor for composing, playing back and sharing hymns and choral music in tonic solfa or jianpu. A score can switch between those notation systems without retyping, and the editor can align lyrics with notes and syllables. Its AI tools include generating alto, tenor and bass parts from a melody, harmonization, transposition, chord suggestions, counter-melody, hum-to-solfa, lyric generation and translation. It imports MusicXML, XML, MXL and MIDI files, as well as photos or PDFs of printed and handwritten scores. Shared scores open in a read-only viewer without an account or installation; embeds can hide DomiSol branding. The free plan includes unlimited scores, playback, sharing and MP3 audio, watermarked solfa and jianpu PDF, and 10 starting AI credits. Audio export is capped at six minutes. Native iPhone and Android apps are in early access. The audience includes church choir directors, music educators and jianpu instrumentalists.
