Current Version: 2.6.1
License: GPLv3 (Open Source)
System Requirements: macOS 11 or later

Application Overview

InputSourcePro is a powerful and meticulously designed input method (keyboard layout) management and switching tool for macOS. Created by a developer (Runjuu) who suffered from the frustration of frequently switching between multiple language input sources, it aims to completely resolve the chaos and errors associated with keyboard switching across multiple tasks and applications. It makes input method switching intelligent, automatic, and seamless.

Core Features & Advantages

1. Real-time Display of Current Keyboard (Input Source)

• Feature: Displays the currently active keyboard layout in an elegant tooltip at the top of the screen.
• Advantages:
  • Clear Visibility: Say goodbye to embarrassing garbled text caused by forgetting your current keyboard.
  • Highly Customizable: You can freely choose when to display the tooltip:
    • When left mouse button is held down
    • When switching keyboards
    • When switching applications
    • Any combination of the above conditions is supported — minimizing distractions while ensuring timely reminders when needed.

2. Application-based Automatic Switching

• Feature: Assign a default keyboard input source to each application.
• Advantages:
  • Smart & Seamless: When switching between applications (e.g., from WeChat requiring Chinese input to VSCode requiring English coding), InputSourcePro automatically switches to the pre-configured keyboard for that app — achieving "app-specific keyboards".
  • Boosted Efficiency: Focus on content creation and communication without manually switching input methods repeatedly, significantly reducing interruptions to your workflow.
  • Wide Compatibility: Fully supports macOS native Spotlight and similar full-screen search apps, maintaining your desired input state even in those interfaces.

3. URL/Website-based Automatic Switching

• Feature: Automatically switches the keyboard input source in your browser based on the website’s domain.
• Advantages:
  • Optimized for Browser Use: Especially useful in scenarios requiring frequent switching between Chinese and English webpages (e.g., Chinese forums vs. English technical documentation sites).
  • Supports Major Browsers: Perfectly compatible with Safari, Chrome, Edge, Firefox, Brave, Vivaldi, and Arc, covering the majority of macOS users.
  • Fine-grained Control: Configure different default input methods for different websites for the most precise automation.

Summary of Core Advantages

1. Privacy-Respecting: As a fully local tool, all rules and settings are stored on your Mac. It never accesses or has permission to read your input content, eliminating privacy risks associated with cloud-based grammar checkers.
2. Lightweight & Efficient: Running as a menu bar app, it operates quietly in the background with minimal resource usage, only intervening intelligently when needed — without impacting system performance.
3. Precision Problem Solving: Designed specifically to address high-frequency pain points for multilingual users and developers. Features are focused, practical, and fully customizable — no bloat.

Download & Installation

• Install via Homebrew (Recommended for Developers):

  brew install --cask input-source-pro
