StockmusicGPT is an AI-powered web app that can generate customizable, copyright and royalty-free stock music tracks. It also features a library of free AI stock music that you can listen to and download. When creating your own track, simply choose a genre like ambient or classical from the dropdown menus, customize options like instruments, theme and length, and let StockmusicGPT work its magic to transform the requests into a short music track. The free plan only allows you to create a single track, so you may wish to double-check that you have the correct options selected on your first try.
