Free AI Music Extender FAQ
Straight answers about extending your audio for free with Grok Music — how it works, what changes, and what doesn't.
Is Grok Music's AI music extender free?
Yes. Start extending music for free with just a few credits — no subscription, no credit card needed.
How does the AI decide what to add to my track?
It listens to your uploaded audio — melody, chord progression, tempo, energy, instrumentation — then composes new material that follows naturally. Think of it as musical autocomplete.
How much extra time can I get from one extension?
Each extension adds a full section — a chorus, bridge, drop, or outro. One well-placed extension usually gets the job done. You can extend again if needed.
Will the extended part sound like it belongs?
It should. The AI uses your file as the musical starting point, so rhythms, harmonies, and instrumentation carry through. Adjust your prompt if something feels off.
Can I extend instrumental tracks without vocals?
Yes. Toggle Instrumental mode and describe the arrangement or energy you want in the next section.
What audio formats can I upload?
MP3, WAV, M4A, and MP4 files up to 10 MB. Most short audio sources are covered.
