Show HN: Smusic.ai – Free AI-Powered Music Generator in the Browser (www.smusic.ai)

Smusic.ai is a browser-based, end-to-end music studio that generates polished songs from simple text prompts. Describe a vibe or reference an artist and the platform’s text-to-song engine produces multi-verse arrangements, lyrics, chord progressions, and radio-ready masters in seconds. Built-in tools include an AI lyric copilot (rewrites, rhyme suggestions, automatic syllable fitting), a library of expressive AI session vocalists plus voice-cloning options, genre-aware auto-mastering, and the ability to upload audio references or stems. You can export WAV masters, individual stems, and MIDI for further production, and collaborate in real time with teammates while tracking listens and trending genres. For AI/ML creators and musicians this lowers the barrier to rapid prototyping and release: non‑musicians can get structured, mix-ready tracks while experienced producers can extract stems/MIDI and iterate in a DAW. Key technical implications include section-aware composition (verse/chorus/bridge), integrated voice synthesis and cloning, and automated mastering tuned to genre dynamics and loudness. There’s a free tier with monthly song quotas and paid plans that grant commercial usage rights and generation provenance documentation—useful for licensing and distribution. Smusic.ai streamlines the full creative pipeline but also raises familiar questions about voice cloning, rights, and provenance that teams should manage with the provided documentation.
