1. LyricToMelody AI
LyricToMelody AI fits a songwriter who has words but needs a vocal blueprint. It generates melodies and sung vocal drafts from lyrics or MIDI, supports custom singing-voice training from uploaded or recorded vocals, and exports MIDI, audio and separate stems for DAW editing. The free Starter plan provides 20 credits and retains projects for seven days; paid plans include commercial rights, with pricing from $10 per month on annual billing. It runs as a web application, so check browser and export requirements before committing.
A practical workflow is: paste a verse and chorus, audition the AI singing voice, export MIDI and audio, then replace or layer the draft in Ableton Live, FL Studio, Logic Pro, Cubase or another MIDI- and audio-based workflow. Use only vocals you have permission to upload; commercial rights are stated for paid plans, while voice-consent details for custom training should be confirmed in the vendor terms.
