Quick answer
LALAL.AI separates up to ten stems including guitar, piano, and synth, adds a voice cleaner, and sells minute packages instead of a mandatory subscription; separation quality is among the best available. Moises offers stem separation plus chord detection, key and tempo change, a metronome, and a mobile app built for practising musicians, on a subscription with a free tier. Producers and DJs lean LALAL.AI; players lean Moises.
Stem separation used to need the original multitrack session. Now a model can pull the vocal out of a finished mix cleanly enough to remix, sample, or practise along with. The two best-known tools take that same capability to different customers.
Separation quality
LALAL.AI's reputation rests on clean stems with fewer artefacts, and on isolating instruments most tools lump into "other", such as acoustic guitar, electric guitar, piano, and synth. For sampling, remixing, and restoration work, that quality is the point. Moises separates well and has improved steadily, but it optimises the surrounding tools more than the last few percent of stem cleanliness.
Practice tools
Moises is built for someone learning a song. Upload a track, mute the bass, slow it down without changing pitch, see the chords scroll by, loop a section. The mobile app makes it usable in a rehearsal room. LALAL.AI has none of this; it returns files.
Pricing
- LALAL.AI: free previews, then lifetime minute packages from about $20 for 90 minutes; minutes are consumed per stem type on some plans, so read the details
- Moises: free tier with limits, Premium subscription for full-length tracks and all tools
- Occasional users save with LALAL.AI's packages; daily practisers get more from a Moises subscription

Bottom line
LALAL.AI if you need the cleanest stems and prefer to pay once. Moises if you are practising an instrument and want the tools around the stems. Both let you try before paying.
