LyricToMelody AI vs Vocalize

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.

Vocalize generates AI cover songs and text-to-speech using voices from its community library or voices users create. On the web, users can train a text-to-speech voice from a short audio sample or make a voice-to-voice RVC model for singing and voice swapping. The searchable library includes uploaded AI voice models and accepts RVC.pth and.index files. Vocalize says text-to-speech takes a few seconds and covers take 10 to 60 seconds; free accounts may wait in a shared queue when demand is high. New signups receive 3 credits without entering a credit card. The REST API supports speech generation, streaming, instant cloning from a 10–30 second clip, direction tags, and 80+ languages. An OpenAI-compatible endpoint can be used for existing /v1/audio/speech integrations by changing the base URL. API usage is prepaid at $0.048 per minute of generated audio plus $0.003 per request, with no subscription. Converter is listed at $9.99 a month, though the page also displays $12.99 and describes paid access as starting at $12.99/mo. Commercial use is restricted unless Vocalize approves it.
