Third-party mice never quite feel right
Scrolling feels choppy, inertia is off, and macOS gives you almost no tuning controls for non-Apple mice.

The problem
Small frictions that add up every day
LinguaX removes the small mouse, voice, and language-switching interruptions that break your focus.
Side buttons are wasted real estate
Most third-party button mapping tools are clunky or app-unaware. You end up ignoring the buttons.
Voice and language switching still breaks focus
Reaching for a key to start dictation, then manually switching input source — every single time.
Core feature
Mouse Enhancement for macOS
Everything your third-party mouse needs to feel like it belongs on macOS.
🖱 Mouse+ Enhancement
Smooth, mappable, per-app configurable
Works with any USB or Bluetooth mouse. No driver install needed — just LinguaX.
Smooth Scrolling
Tunable scroll curve for any mouse, with fine-grained controls for step size, speed gain, and inertia duration. Per-app overrides when one app needs the smooth scrolling toggled. See the smooth scrolling guide.
Gesture & Button Mapping
Map clicks, long-press, and directional drags to real actions: app launch, system controls, media, or custom scripts. Map side buttons →
App-Scoped Overrides
Override any button or scroll behavior for a specific app without touching the global config.
Standout feature
Push-to-Talk Voice Typing on Mac
Hold a mouse side button to start voice dictation. Release to stop. Your hands never leave the mouse.
How it works
One hold. Instant dictation.
LinguaX maps a mouse side button to hold the macOS Fn / Globe key. While held, macOS Dictation activates. Release the button and dictation stops — just like a walkie-talkie. Full setup guide →

Core feature
Automatic Input Source Switching
Set input source rules by app and website so the right language is ready when you switch context.
Your input context follows your focus
Set one rule per app and one per domain. LinguaX switches input source automatically whenever context changes.
Falls back to your default input source when no rule matches. Works in the background, invisible when working correctly. Setup guide for app and domain rules →

Common questions
FAQ
Answers about compatibility, setup, core capabilities, and pricing.
Is LinguaX mainly for mouse enhancement?
Mouse+ is what we lead with — smooth scrolling, gesture/button mapping, and per-app overrides. But push-to-talk voice input and automatic input source switching are equally core capabilities, not add-ons. You get all three.
Do I still get input automation?
Yes. LinguaX also provides app and domain input switching to keep typing aligned with your active context.
What is the pricing model?
Start with a 30-day full-feature trial, then upgrade to a $9.9 one-time Lifetime license only if you want to keep using it.
Is setup complicated?
Usually no. Most users can get a useful first setup in a few minutes and refine later if needed.
Does LinguaX work with any mouse, or only Logitech?
Any USB or Bluetooth mouse. No brand restriction, no driver needed.
