Input Source Pro

Switch and track your input sources with ease ✨

Input Source Pro is a free and open-source macOS utility designed for multilingual users who frequently switch input sources. It automates input source switching based on the active application — or even the specific website you're browsing — significantly boosting your productivity and typing experience.

Features

🥷 Automatic Context-Aware Switching

Set a default input source per application.
Set input sources per website when using browsers (Safari, Chrome, Arc, Edge, Vivaldi, Opera, Brave, Firefox, Zen, Dia, and more).
Switch automatically as you move between apps/websites.

🐈‍⬛ Elegant Input Source Indicator

Shows your current input source with a clean on-screen indicator.
Customizable and designed to stay out of your way.

✍️ App-Aware Punctuation Modes

Keep punctuation consistent across different languages by enabling Force English Punctuation for specific apps.

Automatically types standard symbols (, . ; ' " [ ]) even when your current input source would normally produce localized or full-width characters.
Enable it only for the apps where you need it, such as code editors or terminal windows.

🎛️ App-Based Function Key Switching

Automatically switch your macOS function key mode per app.

Choose whether an app should use F1 ~ F12 as:
- Standard Function Keys: Acts as standard F1 ~ F12 keys. Ideal for IDEs (e.g., VSCode) and games.
- Media Keys: Triggers special features printed on the keys (e.g., brightness, volume, playback). Ideal for general daily use.
Falls back to your system-wide/default setting when an app has no override.

⌨️ Custom Shortcuts

Switch input sources via either:

Keyboard Shortcuts: Use standard key combinations.
Modifier Shortcuts: Use single or combined modifier keys (e.g., Shift, Command, or Shift + Command), triggered by pressing once or double-tapping.
