BeatBun is a web-based music creation platform centered on text-to-song generation. Users describe a mood, genre, scene, or musical direction and receive multiple track variations. It can generate instrumental music, turn lyrics into vocal songs, extend tracks to avoid abrupt endings, and create voice covers from existing or AI-generated audio. Photo-to-music lets an uploaded image guide the soundtrack’s mood. The platform also provides lyric generation, song title and rap tools, an AI BGM generator, 8-bit music creation, MIDI generation and editing, and album cover art tools. Generated ideas can be exported as editable MIDI for further work in a digital audio workstation. Free accounts include trial credits but no downloads or commercial license; paid plans include downloads, expanded credits, storage, and commercial rights.
