For the Clean, Polish, and Formal writing styles, yes. They use Apple Intelligence (Apple’s on-device Foundation Models), so they need
macOS 26 or later with
Apple Intelligence turned on in System Settings → Apple Intelligence & Siri. Every Apple Silicon Mac can run it, as long as Apple Intelligence is available in your language and region.
Without it, transcription is exactly as accurate, since the speech engine doesn’t use Apple Intelligence. What changes is the cleanup: Clean, Polish, and Formal fall back to basic cleanup that removes fillers like “um” and repeated words, but doesn’t rewrite grammar, adjust tone, or create bullet points and numbered lists. Raw works the same everywhere.
Easiest way to check: download VybeScript for free and open it. Before you enter a license, it shows whether your Mac is ready and takes you straight to the right setting if it isn’t. If you buy and your Mac can’t run Apple Intelligence, we refund you in full within 30 days. See
