Soniva is a simple, well-rated song maker: describe a vibe and get a complete song with lyrics, instruments and vocals, royalty-free and ready to share. Like Donna, it lists a Proof of Creation certificate as a separate purchase. Hitz AI takes a different view of what a song you made should cost.

Proof you do not have to buy
A paid certificate answers a real worry: is this song actually mine? The Hitz AI terms answer it in writing, for free. You own the songs you generate, including for commercial use, on every plan. If you ever need formal protection for a work, that is a question for a lawyer or your country's copyright office, not an in-app purchase.
What else is different
Hitz AI gives you four models to choose from, two takes of every song on three of them, three ways to start (describe it, generate lyrics, or paste your own), and a built-in iMessage extension that has been live since June 2026.
Which one is for you
Pick Soniva if you want the simplest possible describe-and-generate app and like having covers and videos on hand.
Pick Hitz AI if you want to own your songs outright without a certificate fee, and want more control over how they sound.
