TL;DR
- A 10 credit free grant covers three songs on the cheapest model and none at all on the priciest, which bills 15 credits a track.
- The same plan billed weekly comes to $259.48 a year. Billed yearly it is $29.99. Nothing else about the plan changes.
- Commercial use is listed as a paid feature, not a free one, so the paywall is about rights more than quality.
- Deezer says it now takes in roughly 90,000 fully AI-generated tracks a day, more than half its uploads, and keeps them out of editorial playlists.
Short version: making the song is the free part. Being allowed to use it, and getting anyone to hear it, is where the money and the rules start.
A free AI music generator with no sign up will hand you a finished song in about a minute, vocals included, and let you download it before it asks who you are. What none of them put on the landing page is how few songs the free allowance actually covers, or which rights stay behind the paywall once it runs out.
The answer is usually a single digit. On OnMusic AI the free grant is 10 credits and the cheapest model charges 3 credits a track, so you get three songs before the meter matters. That is not a criticism of the tool. It is just the shape of the deal across the whole category, and it is worth understanding before you build a project around a free tier.
What “no sign up” actually means
It means the tool removes the account wall, not the meter. You land on the page, type a prompt, and something plays back. The point is to get you to the moment where the thing works, because that moment is what sells the subscription.
So treat “no sign up” as a statement about friction rather than price. Three questions separate the tools that are genuinely usable without an account from the ones that just delay the ask:
- Can you download the file, or only stream it back?
- Does the download carry an audio watermark or a spoken tag?
- Does the licence let you put it anywhere other than your own hard drive?
The third one catches most people out, and it is the one nobody checks until a video gets a claim on it.
The credit maths that decides everything
Nearly every one of these tools now runs on credits rather than song counts, because they are all wrapping several different underlying models and those models cost the operator wildly different amounts to run. A cheap fast model and a flagship vocal model are not the same product, so they are not the same price.
OnMusic AI publishes its per-model cost, which makes the arithmetic easy to check:
| Model | Credits per song | Songs from a 10 credit free grant |
|---|---|---|
| CassetteAI | 3 | 3 |
| ACE-Step | 4 | 2 |
| MiniMax v2.5 | 5 | 2 |
| Sonilo v1.1 | 6 | 1 |
| Stable Audio 2.5 | 8 | 1 |
| MiniMax v2.6 | 8 | 1 |
| Lyria 3 Pro | 10 | 1 |
| ElevenLabs Music | 15 | 0 |
Read the bottom row again. The most expensive model on the platform costs more per song than the entire free allowance, so a free user cannot run it once. That is not a trick, it is just how a shared credit pool behaves when one model costs five times another. But it does mean the free tier is a demo of the cheap models, not a demo of the good ones.
Where the free tier stops
Quality is rarely the thing held back. The paid tiers on most of these platforms unlock rights and throughput, not a secret better model. One example is OnMusic AI, a Free AI Music Generator that hands out 10 credits without asking for an account, then lists commercial use, watermark removal and priority generation on its paid plans rather than its free one.
That ordering tells you what the product actually is. You are not paying for better songs. You are paying for permission to use the songs, and for the queue position that makes generating twenty variations practical instead of painful.
Weekly billing is the expensive part
Here is the number that costs people the most and gets discussed the least. Credit tools tend to offer a weekly price alongside a yearly one, and the weekly price is not a small premium. It is a different product economically.
| Plan | Listed price | Credits | Cost over twelve months |
|---|---|---|---|
| Starter, weekly | $4.99 a week | 150 a week | $259.48 |
| Starter, yearly | $29.99 a year | 150 a week | $29.99 |
| Premium, weekly | $9.99 a week | 500 a week | $519.48 |
| Premium, yearly | $99.99 a year | 500 a week | $99.99 |
Same credits, same features, 8.7 times the money on the Starter tier. The weekly option exists because it converts better, and because most people who take it are gone within a month. If you are genuinely testing for a fortnight, weekly is the right call. If you are still using it in March, it was the most expensive decision you made in January.
What happens to the track after you export it
Two things are worth knowing before you plan anything around a generated song.
The first is crowding. Deezer reported in July 2026 that fully AI-generated music passed half of everything uploaded to it daily, running at roughly 90,000 tracks a day at the June peak. The same Deezer figures put AI music at only 1 to 3 percent of actual listening, because the platform excludes tracks its detector flags from algorithmic recommendations and editorial playlists. Uploading is not the hard part any more. Being surfaced is, which is why the promotion side of this now matters more than it did, and why our guide to running a Spotify marketing campaign is a more useful next read than another tool comparison.
The second is ownership. The US Copyright Office concluded in its 2025 report on copyrightability that prompts alone do not provide sufficient human control to make the user the author of the output. A platform licence can give you permission to use a track commercially. It cannot give you a copyright the law does not recognise, and those are different things that get confused constantly.
Is free enough?
For a birthday song, a placeholder under a video edit, or finding out whether you like the sound of your own lyrics, yes. Three tracks is plenty to answer that.
For anything with a deadline or a client attached, price the yearly plan on day one and skip the weekly button entirely. The free tier is an honest demo of what the technology does. It was never meant to be the thing you build on.
