                        Stemmer FAQ

                        Couldn't people just use LANDR instead of my Stemmer portal?


                        Yes. But even though there are countless AI mastering solutions out there, artists will irrestisably upload songs to your widget when they come across it.

                        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.

                        What if Stemmer sounds bad to me?


                        Somebody else might like the sound. Communicate this as "test our beta AI mastering". Users only have to pay if they want to download their master, and we actually see as much as 9% of uploads get purchased.

                        Is Stemmer hard to install?


                        No. We give you 1 line of html code to embed in your website. It takes 2 minutes
