The best AI music generator depends on what you need to walk away with. For a full song with vocals from your own lyrics, most people start with Suno. For licensed music you can put in an app or a video, ElevenLabs Music. For free and unlimited sketching, Treblo. For instrumentals and loops, Stable Audio; for scores you can open as MIDI, AIVA.
That's the short answer. The longer one is below, with every tool's free plan, price, download rules and commercial terms in one table, checked against each company's own pricing, docs and terms pages on the date at the top.
We build Session Sheet, a prompt studio for Suno: it writes the Styles, tagged lyrics and settings you paste into Suno, and converts them for Mureka, Udio and Google Flow Music. It doesn't make music itself, so it isn't on this list. We're not neutral about Suno, which is why every claim here is a fact you can check at the source, not a judgement about sound.
How we picked
We compared the thirteen tools people actually search for and switch between: what each one makes, how long a song can run, whether it sings your lyrics, how you edit, what's free, what it costs, whether you can download the result, and whether you can release it.
We didn't rank them by sound. Which model's vocals win depends on the genre and the prompt, and changes with every release. Try the free plans on the same lyrics and listen for yourself.
Best for full songs with vocals
Suno is the AI song generator most people mean. v6 sings your own lyrics from section headers, reads a separate Styles field and an Exclude list, and runs up to eight minutes a generation. Editing goes further than any rival here: Extend, Replace Section, Cover, Remix, stems, your own voice on paid plans, and a browser DAW on Premier. The limits: no downloads on Free, and 20 songs a month on Pro ($8 billed yearly) or 60 on Premier. Commercial use covers songs downloaded within that allowance.
ElevenLabs Music is the licensed choice: songs from three seconds to five minutes, section-by-section regeneration, an API, and licensing deals with Merlin, Kobalt and Believe. Paid plans start at $6 a month. Commercial use excludes film, TV, radio and games below Enterprise.
Google Flow Music is Google's chat-driven song studio on Lyria 3.5, what Riffusion became. You make and edit songs by conversation, with covers, section replacement, extension and stem splitting, from $6 a month billed yearly. Downloads, stems included, are on every plan, Free too; commercial use isn't spelled out beyond Google's general terms.
Mureka starts from a reference: upload a track or hum a melody (on Pro). Pro adds WAV and stem downloads, and its site claims full commercial rights. From $8 a month billed yearly.
Mozart AI pairs a song generator with a browser DAW: split a song into stems, turn parts into MIDI and mix it in the same app. Downloads are unlimited on every plan; commercial use needs a paid plan.
Tad AI is the budget pick: up to 50 songs a month for $7.99, with a commercial download licence on every plan.
Udio still makes songs, but downloads have been switched off for every user since October 30, 2025. You can't release from it today; see Udio alternatives.
Best free AI music generator
Treblo, formerly Sonauto, is the free one: unlimited songs with vocals, no credits, with extend, inpainting and stems, and downloads included. Treblo places no restrictions of its own on use.
ACE-Step is free if you have a GPU: an open-weight song model that runs in under 4 GB of video memory and makes songs from ten seconds to ten minutes. Read the model licence before you release.
Suno's Free plan gives 50 credits a day on v6-mini, but no downloads and no commercial rights.
Best for instrumentals, beats and scores
Stable Audio: instrumentals, loops and sound design up to six minutes, with a commercial licence on every plan, Free included.
AIVA: instrumental scores with MIDI export. Only Pro gives you the copyright.
Soundraw: royalty-free beats you can adjust section by section, with streaming distribution on every plan.
Boomy: one-click tracks with distribution to streaming services built in.
Getting more out of whichever you pick
Most disappointing AI songs come from the prompt, not the model: a list of tags, no structure, no ending, and the generator fills the gaps with its defaults. Describe the parts and the performance section by section, and keep negatives out of the main prompt. Our free Styles checker and lyric checker catch the usual problems in a Suno prompt, and the prompt converter rewrites one for Mureka, Udio or Flow Music.
