AI music has effectively two serious options: Suno and Udio. Both turn a text prompt into a full track with vocals. The difference isn’t really quality any more — it’s how much control you want after the first generation.
The 15-second answer
- Fastest path to a finished song: Suno ($8/mo).
- You want to shape, extend and remix it: Udio ($10/mo).

Suno — the one-shot songwriter
Suno is the better tool if you want a finished, listenable song in two minutes. Give it a genre and a mood — or paste your own lyrics — and the V4 model returns something with structure, a hook, and vocals that mostly sit in tune. Its personasfeature is the underrated part: it keeps the same vocal identity across multiple tracks, which is what you need if you’re building a project rather than generating one-offs. It even makes the cover art.
The limitation is that you’re largely accepting what it gives you. If bar 30 is wrong, your main lever is to generate again.
Udio — the one you can actually edit
Udio treats the first generation as a starting point. You can extend a clip to build a full arrangement, inpaintto regenerate just the section that’s wrong while keeping everything around it, and remixto push an existing track in a new direction. For anyone with a producer’s instincts, that’s a fundamentally different workflow — iterative rather than a slot machine.
How to decide
- Background music for a video, today → Suno.
- A track I’ll refine over an evening → Udio.
- Consistent artist voice across an EP → Suno personas.
- One section is wrong and the rest is great → Udio inpaint.
- Cheapest way in → Suno.
A note worth stating plainly: commercial rights for AI-generated music are still unsettled and vary by plan. If you intend to monetise a track, read the current licence terms on the plan you’re actually paying for — don’t assume.
The bottom line
Suno is the songwriter; Udio is the studio. If the output is a means to an end — background music, a demo, a jingle — Suno gets you there faster and cheaper. If the music isthe deliverable and you want to shape it, Udio’s editing tools are worth the extra $2. Full ranking on our best AI music generators page.
