      Stemmer FAQ

      How is Stemmer different than other AI mastering?

      -

      We enable you to choose any reference song from Spotify, and master your song accordingly

      Is Stemmer an ethical AI?

      -

      Yes. Our mastering algorithm currently does not use any machine learning, and has never been trained on any artist's songs. We will never use any songs uploaded to train generative AI models. When users upload, they are shown a clear opt-in form to allow us to use their song to train an AI mastering machine learning model in the future. They do not have to opt-in to use our service. The Spotify reference feature does not rip songs from Spotify. Instead, Spotify's API returns the subgenre of each song, and we master accordingly.

      Will Stemmer steal my song?

      -

      No. You maintain all rights to your song. Our business model is charging directly for the AI mastering.
