BrainRap is an assistive AI which listens to an artist freestyling, singing or writing and suggests words and phrases in realtime for them to use via its visual interface. BrainRap deconstructs both phonetic features and the literal meaning of words and phrases to propose a series of related words and sentences from which the artist can pick, either directly applicable to their current narrative or which could take it in other directions. Its suggestions evolve with their choices in realtime.
