Input Source Pro for MAC

Free, open-source Mac utility that switches your keyboard language automatically for each app and website, with an on-screen indicator.

Input Source Pro Overview

Input Source Pro is made for people who type in more than one language. It switches your input source automatically depending on the app you are using, or even the website you are browsing, so you no longer start typing in the wrong language. Set a default input source for each app, and for each website in browsers such as Safari, Chrome, Arc, Edge, Firefox and Brave, and Input Source Pro changes it as you move between them. A clean on-screen indicator shows which input source is active.

Input Source Pro also lets you force standard English punctuation in chosen apps, such as code editors and Terminal, switch the F1 to F12 keys between function keys and media keys per app, and change input sources with keyboard or modifier-key shortcuts. It is made by Runjuu and is free and open source under the GPL-3.0 license. Version 2.14.0 needs macOS 12 or later.
