LinguaX is a macOS menu bar utility that combines three tools: mouse enhancement, push-to-talk voice input, and automatic input-source switching. It is built for people who use third-party mice on a Mac and find that scrolling feels choppy, side buttons go unused, and switching languages or starting dictation interrupts their work. It is designed by Ermulin Studio and requires macOS 13 or later.
The app is written in Swift rather than Electron and is roughly 10MB, according to the company. It works with any USB or Bluetooth mouse without a driver install, and it needs no account. Rules are stored locally, with optional iCloud sync. The company leads with Mouse+, but says voice input and input switching are equally core capabilities, not add-ons.
For mouse control, LinguaX sits in the menu bar and changes how a connected mouse behaves. Smooth scrolling uses a tunable curve with controls for step size, speed gain, and inertia duration. Clicks, long-presses, and directional drags can be mapped to actions such as launching an app, system controls, media, or custom scripts, and any of it can be overridden for a specific app.
Push-to-talk works by mapping a side button to hold the macOS Fn / Globe key. While the button is held, macOS Dictation is active, and releasing it stops dictation, much like a walkie-talkie. Input switching is rule based, with one rule per app and one per website domain. When no rule matches, LinguaX falls back to the default input source and runs quietly in the background.
Mouse+ covers smooth scrolling, gesture and button mapping, and app-scoped overrides. The company says it works with any third-party mouse, while its comparison table lists Logi Options+ as Logitech-only and macOS built-in controls as limited. Per-app scroll overrides let one app turn smooth scrolling on or off without touching the global setup. The product tour shows screens for rule status, input rules, feel tuning, and permissions.
Push-to-talk voice typing is listed as working with macOS Dictation, Wispr Flow, superwhisper, and any push-to-talk app. Input source automation is shown with examples such as Xcode set to English, WeChat set to Chinese (Pinyin), linear.app set to English, and zhihu.com set to Chinese (Pinyin). An optional feature called AIx sends text only when the user requests an action and agrees to the transfer.
