Music generation
The free, unlimited song generator (formerly Sonauto) that made "RUBBERZ," the first AI song on the Hot 100.
Treblo is a full-song generator, formerly called Sonauto, that bets on being completely free: unlimited songs on its latest model, no daily caps, and full rights to what you make, including commercial use. It supports more than 4,000 style tags and several languages, and lets you regenerate sections, remix, cover songs in new styles, go instrumental and export as MP3, WAV, FLAC and more. In August 2026 it became part of music history when co-founder Ryan Tremblay confirmed Fenix Flexin's "RUBBERZ" was made on the platform, the first known AI-generated song to reach the Billboard Hot 100, after Zinstrel and HumanStandard reported it in June. Treblo released an open-source classifier alongside the confirmation, though it only detects songs made on Treblo itself.
