The desktop app is a lightweight native window around Replicas, so it tracks web deployments without requiring a new download.

On macOS, open the DMG, drag Replicas into Applications, and launch it. Builds require macOS 12 or later. On Linux, run an AppImage from its download directory:
Or install the Debian package on Debian or Ubuntu:
Sign in as you do on the web app. On macOS, Google and Apple sign-in open in your default browser, where passkeys and security keys work, then return you to the app. On Linux, OAuth stays inside the app. Slack and Linear connections open in an app window on every platform. Other external links open in your default browser.

​
Appearance

Select Theme in the account menu at the bottom of the sidebar to cycle through Light, Dark, and System. The desktop app follows your selection, including the macOS title bar. System follows your operating system’s appearance. On Linux, window borders follow your desktop environment’s theme.

​
Voice input on macOS

Select the microphone in the Home or workspace composer, or press Command+Shift+Space, to dictate a prompt. Press the shortcut again or select stop to finish, then review the transcribed text before sending it. While listening, the composer shows elapsed time and a waveform that responds to your microphone volume. The same feedback appears when you use voice input in a supported web browser. The macOS app asks for microphone and speech recognition access the first time you use voice input. On macOS 26 and later, it uses Apple’s on-device Speech Transcriber. Older macOS versions use Apple’s legacy speech recognizer.

​
macOS turn notifications

Replicas sends a native notification when a turn finishes while the app is minimized or in the background. If messages remain queued, Replicas waits until every queued turn finishes. Only regular workspaces visible with your active sidebar views and filters can trigger notifications. Select the notification to reopen its workspace. Notifications are suppressed while the app is focused. Closing the window keeps Replicas running so notifications can arrive. Quit Replicas with Command-Q to stop background notifications. Turn on Open links in the desktop app under Dashboard → Personal → Preferences to hand app, dashboard, and workspace links off to the desktop app. A Replicas link you click in Slack, Linear, or GitHub opens the app on that page instead of a browser tab, on every browser you are signed in to. Links to other pages, such as sign-in and marketing pages, stay in the browser. Add ?desktop=0 to any link to keep that one in the browser too. The setting only takes effect on macOS and Linux, where the app runs. Without the app installed the page stays in your browser, though browsers that ask before opening an app still ask first. Each browser tab attempts the hand-off at most once, so that prompt cannot repeat as you move around the app. The macOS app checks for desktop updates automatically. When an update is ready, restart immediately or choose Later to install it the next time you open the app. Linux users install new packages from this page. Web app updates appear without a desktop update.
