Small app. Capable device.
Download Space,
not another browser.
Space uses the AI, speech and voices available on your Mac first. Models are prepared only when a supported feature needs them. It does not bundle every language or multiple large model copies in the installer.

Before you install
Does everything run offline?
Available local conversation and speech run on your device after their assets are ready. Mail, internet search, syncing, initial app loading and publishing need a connection. Space blocks cloud AI routes. Some image and advanced AI features remain unavailable until a supported local route is ready.
Which Mac features are supported?
The app opens on macOS 26 or later. Apple Intelligence needs an eligible Apple silicon Mac and an available system model. Computer-task planning needs macOS 26.4 or later for its model context checks, plus a ready supported local model. Accessibility, screen sharing and app-control behavior must also be supported on your Mac.
Which languages are available?
Apple Intelligence requires an eligible Apple silicon Mac, enabled system AI, and a supported language. Your language setting controls the supported local speech and voices shown in Space. English is the default. Language availability and downloads depend on your Mac; Space does not install every language pack.
Can my agent use any app or run a script?
Computer tasks are limited to supported browsers, Finder, document, spreadsheet, Mail and Calendar apps. The agent cannot run arbitrary shell commands or AppleScript, operate password managers, or change system permissions. Control stops when the app or Space session closes.
What about Windows, Linux and mobile?
Use Space on the web today. A download is listed here only after a real installer for that platform is signed and published. This page does not offer a Lettuce.Vision browser installer.
