Treblo Review

Treblo generates complete songs with vocals and instruments from a short description, your own lyrics or lyrics it writes for you. You combine tags from a list of 4,160 styles (pop, metal, K-pop, drill, lo-fi and many sub-genres), and the track starts streaming in about 15 seconds while the rest renders. After generation you can rewrite lyrics, regenerate sections you dislike (inpainting), extend a track, cover a song in a new style, remix other users' songs and separate stems. There is an instrumental mode, and songs can be kept private, shared unlisted or published to your profile, groups and the site's radio.

Treblo is run by Sonauto, Inc., a four-person team that renamed the product from Sonauto to Treblo in June 2026; old sonauto.ai links redirect. It runs its own music model (the homepage names it Melodia v3) rather than reselling another lab's. It works in the browser and in an iOS app, and Treblo says it sings well in Latin-alphabet languages, while Japanese, Korean, Chinese, Arabic, Russian and Hindi work but pronunciation may be off.

For people making songs in the app, Treblo is free: its homepage and FAQ promise unlimited songs on its latest model, with no credits and no daily limits, and downloads in OGG, MP3, WAV, FLAC and M4A. No paid consumer plan is listed on the site, and the iOS app is listed as free.

Developers pay for the API:

One song costs 100 credits, and asking for 2 songs at once costs 150. That is $0.055 a song on Starter ($11 / 200), the same on Pro ($88 / 1,600), and $0.06 a song pay-as-you-go. Plan credits reset each billing period; pay-as-you-go credits never expire. Any user-facing product built on the API must credit Treblo.

Prices checked on the vendor's pricing page on November 3, 2026. See Treblo API pricing.

What Treblo lists on its homepage, FAQ and developer pages:

Treblo suits hobbyists, video creators who need lots of throwaway tracks, people making personalised gift songs, and developers who want a cheap song API at about 6 cents a song. Because there is no credit meter, it is easy to iterate on a prompt dozens of times.

If you want a bigger community, more polished tools or a long track record, compare Suno. If you want to edit a song by chatting with an assistant and download stems, Google Flow Music is a close alternative. Songwriters working in non-Latin scripts should test pronunciation first, as Treblo itself flags it.

The iOS app has 4.8 stars from 437 ratings on the App Store. Under its old name, Sonauto drew mixed comments on Reddit: some users like its melodies and smoother vocals and use it to sketch ideas, while others say it follows lyrics and vocal melody loosely; its Trustpilot page has few reviews. In August 2026 Stereogum reported Treblo's claim that Fenix Flexin's Hot 100 song Rubberz was made with Treblo, based on Treblo's own detector; the artist initially denied using AI.
