+# Desktop app
+
+**English** · [Português](pt-BR/interface.md)
+
+The desktop app (Tauri) and the browser version (`sabia ui`) are the same front-end, in `apps/gui/ui/`. Only the transport differs: the desktop app talks to the core through Tauri; in the browser, `sabia-cli` starts a local server on `127.0.0.1` protected by a token generated on the spot.
+
+## Screens
+
+- **Interface sidebar:** lists the Wi-Fi interfaces; pick one to work with. The footer has the version and the one-click **update** button.
+- **Capture panel:** header with the current mode (managed/monitor), an **animated signal line**, and the **enable monitor mode** and **start capture** buttons.
+- **Authorized-use notice**, always in view: use only on your own networks or with authorization; every monitor activation and capture goes into the local audit trail.
+- **Networks seen:** live table with SSID, signal bars, channel and a color-coded security badge (open, WEP, WPA/WPA2, WPA3).
+
+## Privilege
+
+Monitor mode and capture require root/admin. On startup, the app elevates automatically (on Linux and macOS it restarts elevated; on Windows, via the manifest). A notice appears while elevation is requested, with a retry option.
+
+## Themes and language
+
+**Auto, Light and Dark** themes and interface in **Portuguese and English**. The system language is detected at start; the choice is saved. The source text is Portuguese and English is applied at runtime (see `apps/gui/ui/i18n.js`).
