LyricToMelody AI vs SightSinger

LyricToMelody AI turns lyrics or other musical ideas into melody drafts, AI vocal demos, and editable MIDI. Users can provide a verse, chorus, hook, or full lyric sheet and label sections such as verses, choruses, and bridges. Melody ideas are shaped around syllables, pacing, and song structure. Listed exports include MIDI, WAV, and MP3; Starter also includes PCM. The service describes its MIDI and audio workflows as working with Ableton Live, FL Studio, Logic Pro, Cubase, Studio One, and other DAWs. Other listed tools include MIDI-to-vocals, text-to-MIDI, multi-track generation, and vocal removal. Starter is free and provides 20 starting credits with seven-day project retention. Creator costs $10 a month billed annually, or $120 a year, and includes 1,200 monthly refreshed credits, MIDI and audio export, commercial rights, and 30-day retention. Studio costs $30 a month billed annually, or $360 a year, with 3,600 refreshed credits and one-year retention. Files may be stored during processing and the retention period; projects and files can be deleted from the dashboard.

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.
