The AI DJ lets you control playback with natural language. Instead of hunting for buttons, you type what you want — “mute the vocals”, “loop 4 bars”, “speed up” — and StemFM does it in real time.

The AI DJ command pill with its list of example commands — The AI DJ — type a command, or open help for examples.

Where to find it

During a session, open the DJ command pill and type a command. The pill shows rotating example hints when it is empty, and a “?” button opens a help popup grouped by what each command does.

What you can say

Tempo — “Speed up”, “Slow down”, “128 BPM”, “Half speed”, “Normal speed”.
Stems — “Mute the vocals”, “Solo the drums”, “Vocals at 50%”, “Unmute everything”.
Skip & seek — “Next track”, “Smooth skip”, “Jump to 1:30”, “Rewind 10 seconds”.
