Frequently Asked Questions
Do I need to be online to use Prism?
After a one-time online activation, Prism runs fully offline on your machine. The app does a lightweight check-in periodically when you're connected, but there's a generous grace period so you can work offline for extended stretches without interruption.
Is there a limit on how many songs I can process?
No limits at all. Process as many tracks as you want — there are no per-song charges, no credits to buy, and no monthly quotas.
What does "own forever" mean?
When you buy Prism Core, you own that version permanently. Your license never expires and the app keeps working. You also get 1 year of free updates including new AI model improvements. After year one, everything you have still works perfectly. If you want the latest model updates after that, you can renew at a loyalty discount.
Does Prism work on Intel Macs?
Yes. Prism Lite works on Intel Macs via CPU processing. Prism Core works on Intel too but without GPU acceleration — for the best performance, Apple Silicon (M1 or later) is recommended.
What's the difference between Lite and Core quality?
Prism Core uses a more advanced AI model that produces significantly cleaner separation with fewer artifacts, especially on complex mixes. It also separates into 6 individual stems vs 2.
Will there be a Windows version?
We're focused on macOS first. Windows support is on the roadmap but doesn't have a confirmed date yet.
