Good question. Roon and Audirvana show "similar artists" based on metadata. You get a short list of names, usually well-known artists in the same genre. It's useful, but it stays close to what you already know. Roon's radio feature goes a bit further, but it creates a temporary station. Once it's done, it's gone. Nothing saved, nothing to go back to.
Sonic Oracle does something different. You give it a seed artist and it builds a full playlist of artists connected to them by taste, style, and sound. Three depth levels, from close matches to deep cuts. Most of the results are artists you've never seen in any "related artists" tab. And those playlists are permanent. They stay in your Tidal or Qobuz library.
It doesn't compete with Roon or Audirvana. It feeds them. The playlists land in your library and Roon, Audirvana, and everything else picks them up instantly. I use Roon myself. Sonic Oracle fills my library with music I'd never find through Roon's own recommendations.
