Is Treblo really free?

Yes. The free plan generates unlimited songs on the current Melodia v3 model, including inpainting, extending, stem separation and downloads in every format. Pro is an optional subscription that adds queue priority and beta features rather than unlocking generation itself.

Can I use songs I make on Treblo commercially?

Treblo states there are no usage restrictions on songs you create, on the free plan as well as Pro, and its comparison table lists commercial use as included rather than paywalled. Downloads are available in OGG, MP3, WAV, FLAC and M4A.

What happened to Sonauto?

Sonauto is the same product under its old name. The team renamed it Treblo in June 2026, moved it to treblo.com and kept accounts, songs and shared links working; sonauto.ai links redirect, and the API host moved to api.treblo.com.

Does Treblo have a developer API?

Yes. The Melodia API generates songs programmatically with streaming responses and webhook support. New developers get 3,000 free credits after card verification, and paid plans start at $11 per month for 20,000 credits.

What is Treblo?

Treblo is an AI music generator that turns a text prompt into a finished song — sung vocals, instruments and structure included — using Melodia, the model its own team built, now at version 3 (Melodia v3). Until June 2026 the service was called Sonauto; the four-person team renamed it, moved it to treblo.com, and carried every account, song and shared link across. A song starts streaming in about 15 seconds, and each one is steered by style tags — the site counts more than 4,160 of them, spanning genre, mood, era and instrumentation.

Generation is not metered. The free plan makes unlimited songs on the current model and bundles in the editing tools: inpainting a section, extending a track, separating stems. Downloads come in OGG, MP3, WAV, FLAC and M4A, and Treblo states there are no usage restrictions on songs you create. Money comes from an optional Pro subscription (priority queue, beta features) and from a credit-based Melodia API for developers. Treblo suits hobbyists and creators who want songs fast, and developers who want to generate music inside their products.
