What is Sonauto?

Sonauto is an AI music generator that turns text prompts, lyrics, or melodies into complete songs with vocals and instrumentation. Founded in San Francisco in 2023 and backed by Y Combinator, the company built a music foundation model called Melodia that produces full songs, including up to 4.5 minute tracks with its latest engine, in a wide range of styles and languages. As of 2026 the product has rebranded from Sonauto to Treblo, with the sonauto.ai domain now redirecting to treblo.com, though user accounts and existing songs carried over unchanged.

The web app lets users generate songs from simple prompts or detailed style tags, switch between vocal and instrumental modes, and separate finished tracks into stems such as vocals, drums, bass, and instruments. It also includes a social layer for sharing tracks, following artists, and browsing curated playlists and radio. The consumer product is free with no stated song limit, while a separate paid API serves developers who want to integrate music generation into their own applications.
