Moises
AI music practice app that splits any song into stems and detects chords in real time.
Overview
Moises: practice with the real recording, minus whatever's in your way
Moises is an AI music practice and creation app that separates any uploaded song into isolated stems — vocals, drums, bass, and instruments — so musicians can mute the part they play and practice against the real recording. Around that core it layers real-time chord and key detection, a speed changer that preserves pitch, a pitch changer for transposition, synced lyric transcription, and a smart metronome. Founded in 2019 by Geraldo Ramos, Eddie Hsu, and Jardson Almeida, the app (from parent company Music AI) claims more than 75 million users and was named Apple's iPad App of the Year in 2024.
Beyond practice, a Voice Studio provides AI vocal models for track-ready performances, an AI Studio generates stems, and in-app video recording captures performances with studio-quality audio. It runs on iOS, iPad, Android, web, and desktop.

Ideal Use Case
A guitarist learning a song by ear who wants the guitar track muted and the tempo at 70% without the key drifting — or a singer who needs the original vocal isolated for study, then removed for performance. The free tier's limited monthly uploads suit occasional use; regular practicers step up to Premium ($5.99/month or $39.99/year), and audio professionals to Pro ($29.99/month) for the highest-quality separation.
How Moises differentiates
Web stem-splitters like LALAL.AI do one-shot extraction; Moises wraps separation in a complete mobile-first practice suite — chords, tempo, metronome, lyrics, recording. Unlike Ultimate Guitar or Chordify, its chords come from your actual audio alongside playable stems, not crowd-sourced tabs. Production credibility: 75M+ claimed users, Apple iPad App of the Year 2024, a 4.7/5 App Store rating across 27k+ reviews, a $40M Series A for parent Music AI (January 2025, Connect Ventures and Monashees), and Charlie Puth as Chief Music Officer.
