Moises is an AI-powered app for musicians that separates any song into isolated tracks such as vocals, drums, bass, guitar, and piano, so players can remove a part to practice along with the rest or study individual instruments. Built on source-separation models, it also detects key and tempo, offers pitch shifting and time stretching without artifacts, generates chord charts automatically, and provides a metronome and section looping for practice. Musicians use it to create backing tracks by muting their own instrument, transcribe parts by soloing them, transpose songs to fit a vocalist's range, or slow down difficult passages while keeping pitch intact. Moises has added features for building set lists, syncing lyrics and chords, and collaborating with bandmates on shared songs. It is available on the web, iOS, and Android, with a free tier that limits the number of uploads and higher-quality processing reserved for paid subscriptions aimed at gigging musicians, teachers, students, and content creators. The company also licenses its separation technology to other products through an API. Moises is positioned as a practice and preparation tool rather than a production suite, focused on helping individual players learn and rehearse music faster.
