How it works
Desktop workspace
A local-first desktop app for screening and analysing your library at scale. Your projects stay on your device. Free while in beta, for Mac and Windows.
Open Studio to find your device's licence ID (Settings), then request beta access.
Request free access →First launch shows one safety screen — this is normal and safe. The download is a .zip, so unzip it first. Windows: run the setup; if you see “Windows protected your PC,” click More info → Run anyway. macOS: open the .dmg, drag Studio to Applications; if macOS says it “could not verify” the app, open System Settings › Privacy & Security and click Open Anyway. You only do this once.
