Muzio is a well-reviewed song maker with a clear pitch: write or generate lyrics, pick any genre, and get a produced song in seconds. It can also sing in your own vocal tone and make instrumentals. Hitz AI covers the same ground on lyrics, genres and instrumentals, and adds a choice of models and a way to make songs inside iMessage.

MuzioPrices are the in-app purchases shown on each app's US App Store listing on September 25, 2026. Offers vary by region and over time.
Where they overlap
Both apps let you write lyrics or have them written, choose a genre, and make an instrumental instead of a vocal track. If that is all you need, either will do the job. The difference is in what happens around the song.
Where Hitz AI goes further
- Four models. Choose V8 Fast, V8 Pro, V8 Evo or V8 Raw for each song, depending on whether you want speed, control, surprise or simplicity.
- Two takes. Three of the models return two versions of every song for one price.
- iMessage. Make and send a full song without leaving the conversation.
- Ownership. The terms say you own the songs you generate, commercial use included.
