Switch your Mac’s keyboard language automatically, per chat
Tact
The right keyboard, before the first word.
Tact switches your Mac’s keyboard to the language you last typed in each window, WhatsApp Web chat or Claude thread, so you start typing in the right one.
It reads the box you type in and the text around it, keeps none of your text, and nothing leaves your Mac.
Tact is a Mac app. Open this page on your Mac to download it.

Per chat, not only per app
Tact tells one WhatsApp Web chat from another, and one Claude thread from another, and remembers the language you used in each. Your chat in Hebrew stays in Hebrew, and the English one beside it stays in English.
With the keyboards you already have
Hebrew and English, Russian and English, Arabic and French: Tact works with the keyboards you’ve already added to your Mac, and picks the right one when you arrive to type.
