Donna AI Song & Music Maker is one of the most popular AI music apps on the App Store, and it does a lot: songs from a description, from your own lyrics or from a photo, plus covers, music videos and stem separation. Some of those are sold separately from the subscription, which is a legitimate way to price a wide product. It also means the cost of one finished song, yours to keep, is worth a closer look.

About certificates
Donna sells a Proof of Creation certificate for $16.99, on top of the subscription. We understand the appeal: people want something that says the song is theirs. Our view is that you should not have to buy that feeling. The Hitz AI terms say you own the songs you generate, commercial use included, on every plan. There is no document to buy because there is nothing to unlock.
What is in the price
Donna's listing is clear that Extend, stem separation and Proof of Creation sit outside the subscription, and its in-app purchases also list AI Cover and AI Music Video at $5.99 each. If you want those tools, that is honest pricing for them. Hitz AI has one meter: credits. A credit makes a song, credit costs vary by model, and nothing is sold afterwards to use what you made.
Sending the song
Hitz AI gives you the MP3, so a friend gets a song that plays in the thread, not a link that asks them to install something. With the built-in iMessage extension you can make the song inside the conversation too. For a lot of people that is the whole point of making a song, so we put it first.
Which one is for you
Pick Donna if you want the broadest toolkit on one screen, including photos to songs, videos and stems, and you are fine paying for the pieces you use.
Pick Hitz AI if you want a full AI music generator on your iPhone, four models to choose from, and every song owned outright with nothing to unlock.
