Hookgen is a web app that uses artificial intelligence to create brand new, original songs with music hooks that can be sad or happy, and either simple or complex. It allows users to generate new music hooks, songs with intro, middle and outro sections, and download the MIDI file or share the generated song via a URL. Hookgen is free to use and the songs generated are royalty-free, even for commercial use. Its AI engine learns to produce better songs every time a user interacts with the app, and it can be used on desktop computers or laptops.
