Aimée, the AI-powered assistant in YouCompose, stands out by ensuring that the music she helps you create is entirely original and free from copyright issues. Aimée Doesn't Steal! Aimée's AI isn't trained on existing musical data. Instead, she generates her own unique musical content. This innovation is achieved through the clever use of an expert system that combines music theory with advanced genetic algorithms. As a result, Aimée produces truly original compositions that are not based on or derived from existing works. At the heart of Aimée's originality is an expert system grounded in comprehensive musical theoretical data. This system provides Aimée with a deep understanding of music, enabling her to compose with creativity and precision. Whether you're crafting a symphony or a simple melody, Aimée applies her theoretical knowledge to ensure your music is harmonically rich and structurally sound. Aimée also leverages genetic algorithms, which allow her to evolve and refine musical ideas through a process akin to natural selection.

This approach is crucial in addressing potential copyright infringements. By not relying on pre-existing musical data, Aimée ensures that the music you create with her assistance is genuinely yours.
