Every app here can take a description and hand back a full track with singing. That was science fiction three years ago and now it is a crowded App Store category. The useful question is not which model is best this month. It is what happens after the song exists: can you keep it, can you send it, is it yours, and did you have to fight the app to get there. For side-by-side detail on any one of them, see the comparison pages.

Hitz AI: a full music generator in your pocket
Describe the song, paste your lyrics or let the app write them, set one of 21 genres or your own custom style, pick a mood and a voice, choose one of four models, and the result lands in your Library as an MP3 you can send anywhere. The built-in iMessage extension has been live since June 2026, and the other person needs nothing to hear the song. The terms say you own what you make, commercial use included. No download meter, no certificate to buy.
Suno: the studio everyone knows
The biggest community, a capable web editor, steady model updates and an iPhone app that keeps up. The trade is a download allowance: seven for the life of a free account, twenty a month on Pro, sixty on Premier, with extra download credits sold individually. Hitz AI vs Suno.
Udio: for refining a track
Udio shines when you want to keep working on a song after the first take. It is web-first with an iPhone app. Since its Universal Music Group partnership, its help centre says downloads of audio, video and stems are disabled, so check before you rely on a file. Hitz AI vs Udio.
Donna: the biggest toolkit, priced by the piece
Songs from text, your own lyrics or a photo, plus covers, music videos and stem separation. Extend, stems and a $16.99 Proof of Creation sit outside the subscription. Good if you want everything on one screen. Hitz AI vs Donna.
Mureka: a platform for remixing
Mureka is a place as much as a tool: a radio feed of AI songs, remixes, and voice cloning. Worth a look if you want to be inside a music community. Hitz AI vs Mureka.

Questions
Which AI song generator lets you download every song?
Hitz AI lets you download every song you make as an MP3, with no monthly cap and no per-download fee. Making songs uses credits, and you get free credits to start.
Do these apps require the other person to install them?
Mostly yes. A share link from Suno, Udio, Donna or Mureka opens in that app. Hitz AI hands you the MP3 instead, or makes the song inside iMessage, so the other person needs nothing.
Which AI music apps have an iMessage extension?
Hitz AI has had one built in since June 2026, making full songs the other person can play without installing anything. Suno added an iMessage feature in July 2026; launch coverage noted both people need Suno and songs are 30-second clips.
