How we verified this
We don’t run generation tests, we read the fine print. For Treblo (formerly Sonauto) we read the free tier’s own terms, its commercial-use, watermark and attribution rules, then confirmed the cheapest plan that lifts them against the official pricing page, cross-checked across multiple current sources. The watermark and license clauses below are paraphrased from those terms, and the quality score is our editorial read of the tool, not a lab benchmark. Everything here was last verified June 22, 2026.
Watermark & licensing, the part that decides monetization
Why the free plan fails: Treblo's own FAQ and Terms state it places NO usage restrictions on songs you create and that whatever rights exist in the output belong to you, not Treblo, even on the free tier, with downloads in all formats. That is an unusually creator-friendly stance, making it one of the few genuinely free-tier-monetizable options. The remaining caveat is that the dedicated Terms page is JS-gated, so the exact Section 8 wording wasn't quotable verbatim.
Watermark
No watermark is indicated. The FAQ states there are no usage restrictions on songs you create and that you can download in all formats and use them in your videos, implying clean, unwatermarked output on the free tier.
License
Per the FAQ and a cited Terms of Service Section 8 (Output), Treblo places no usage restrictions on created songs and any rights in them belong to the user, conditional on the user's inputs being their own. The standalone Terms page is JS-gated, so the exact Section 8 text could not be captured verbatim.
“We place no usage restrictions on songs you create, and whatever rights may exist in them belong to you, not us. As long as what you put into them is yours, the rest is your call: post them, share them, put them in your videos.”
Pros & cons
Pros
- Unlimited free songs on the latest model with no daily limit
- No usage restrictions; output rights belong to the creator (FAQ + ToS Section 8)
- All-format downloads + editing tools (inpainting, extending, stem separation) on free
Cons
- Dedicated Terms page is JS-gated, so Section 8 couldn't be quoted verbatim
- Recently rebranded (Sonauto to Treblo), links/branding in flux
- Free-tier sustainability/business model risk for a fully-free product
Pricing, which plans are actually safe
| Plan | Price | What you get | Monetization |
|---|---|---|---|
| Free | $0.00 | Unlimited songs on latest model (Melodia v3), generation/inpainting/extending/stem separation, all-format downloads, no usage restrictions | Safe |
Affiliate link, commission costs you nothing and never changes a verdict.
Alternatives we’ve tested
Suno8.5
AI music · AI songs, free tier non-commercial
Free-tier songs are licensed for personal, non-commercial use only and must credit Suno, so you cannot monetize them.
Udio2.5
AI music · AI songs you can't download
Since the Universal Music Group partnership, downloading audio, video, and stems is disabled for all accounts, so a free user cannot export a song to put behind a monetized video at all.
Mureka7.4
AI music · Generate full royalty-free tracks in seconds, but the free tier is non-commercial AND attribution-required; you must pay to own and monetize.
The free tier is a clear no for monetization: Mureka's own Terms state that on the free tier Mureka owns the Output and licenses it to you for lawful, internal, and non-commercial purposes only, provided you give attribution credit to Mureka. Commercial ownership only kicks in on a paid tier.
FAQ
Can I use Treblo songs commercially on the free tier?
Yes. Treblo's FAQ states it places no usage restrictions on songs you create and that rights in them belong to you, as long as your inputs (e.g. lyrics) are your own. See ToS Section 8 (Output).
Isn't this Sonauto?
Yes, Sonauto rebranded to Treblo (same team, same account). It now lives at treblo.com.
