In their own words
SightSinger
SightSinger turns MusicXML sheet music into singing audio demos through a natural-language chat workflow. It is designed for score-led rehearsal and demo work, not writing songs from text prompts or full studio production. Choir and worship leaders can make section references and part-learning demos, including split SATB parts; music teachers, songwriters, arrangers, and independent singers are also named users. The site recommends.xml or.mxl files exported from MuseScore, Finale, Sibelius, Dorico, or Logic Pro. Its multi-track player supports score highlighting, repeats and endings, per-track mute, solo and volume, instrument sound changes, and mix downloads. Users can add movable-do or fixed-do solfege, including la-based or do-based minor options. SightSinger says it detects lyric language and supports Mandarin Chinese, Cantonese Chinese, Japanese, Thai, English, Spanish, French, Italian, Portuguese, and European Portuguese. Listed voices have voice-specific language and style support. Vocal audio costs one credit per 30 seconds for each vocal part each time it is rendered; MIDI accompaniment uses one credit per two minutes per uploaded score. The web service offers a free plan with eight monthly credits and paid plans from $6 per month.
