Boomkey vs Punto Switcher vs Caramba Switcher
If you type in two alphabets, you know the problem: the text comes out as gibberish because the wrong keyboard layout was active. Several Mac apps solve this in different ways. Here is an honest look at how Boomkey compares to the alternatives people ask about most.

Looking for a Punto Switcher alternative for Mac?
Punto Switcher is the app most people mean when they talk about automatic layout switching, but it is effectively a Windows product. It is owned by Yandex, and while a macOS build did exist, public version histories show it stopped being updated many years ago. There is no current, maintained Mac release to install on a modern system.
That leaves Mac users looking for something that does the same job on macOS 14 and later. Boomkey takes a deliberately different approach: instead of guessing what language you meant and flipping the layout mid-sentence, it fixes the text after you typed it. Press space and the wrong-layout word is rewritten, or select any text and double-tap Shift to convert it. Nothing is switched behind your back, so you never fight the app for control of your keyboard.
If you specifically want proactive auto-switching rather than after-the-fact correction, Caramba Switcher is the closer match to what Punto did.
Caramba Switcher vs Boomkey
Caramba Switcher is made by Sergey Moskalev, the original author of Punto Switcher, so it is the most direct spiritual successor. Its Mac App Store listing shows English and Russian as the supported languages, and it is distributed as a free download with a $6.99 per year auto-renewing subscription. It requires macOS 12 or later and is actively maintained.
The two real differences for most people are language coverage and payment. Caramba does not list Ukrainian support; Boomkey was built Ukrainian-first, and its hotkey conversion works with any pair of alphabetic layouts you have installed — Latin, Cyrillic, Greek, Hebrew, Arabic, Georgian, Armenian, and Korean. Boomkey is also a one-time purchase rather than a yearly subscription.
Caramba is not only an auto-switcher — it also converts the last word with a double-Shift, much like Boomkey. So the honest framing is not "switching vs. correcting" but which language pairs you need and whether you would rather pay once or every year.
Smart Language Switcher vs Boomkey
Listed on the App Store as Smart Language Switcher (often searched as "Lang Switcher"), this app auto-switches your layout while you type. It runs on macOS 10.15 and later, and offers annual plans between $7.99 and $11.99 or a lifetime unlock between $23.99 and $29.99. Its most recent update was in February 2025.
The developer does not publish a list of supported keyboard layouts, so we cannot tell you whether a given pair works — a review thread on the listing indicates Japanese and Korean input methods are not supported. Boomkey states its coverage explicitly: the hotkey converts between any two installed alphabetic layouts, and auto-correction on space is in beta for English paired with Ukrainian, Belarusian, Hebrew, or Russian.
Which one to pick
If you want the layout to switch itself as you type and you work in English and Russian, Caramba Switcher does that and is actively maintained. If you are on an older macOS and want proactive switching, Smart Language Switcher is worth a look, though its layout support is undocumented.
Choose Boomkey if you type in Ukrainian, Belarusian, or Hebrew alongside English, if you want the app to fix text rather than take over your layout, if you need conversion between unusual layout pairs, or if you would rather pay once than subscribe. Everything is processed locally on your Mac, and there is a 7-day trial with no card and no account.
Frequently asked
Is there a Punto Switcher for Mac?
Not a current one. Punto Switcher is a Yandex product that is maintained for Windows; the macOS build has not been updated in years, so there is no supported version for a modern Mac. Boomkey and Caramba Switcher are the two actively developed Mac apps that solve the same problem.
How do I fix text I typed in the wrong keyboard layout?
With Boomkey you do not retype it. Select the text and double-tap Shift and it is converted between your two layouts instantly. If you have not selected anything, it fixes the last word you typed, and with auto-correction enabled a wrong-layout word is rewritten as soon as you press space.
Does Caramba Switcher support Ukrainian?
Its Mac App Store listing names English and Russian as the supported languages and does not mention Ukrainian. Boomkey supports Ukrainian directly, both for auto-correction on space and for hotkey conversion.
Do any of these apps work without a subscription?
Boomkey is a one-time purchase with free lifetime updates. Caramba Switcher uses an annual subscription. Smart Language Switcher offers both an annual plan and a lifetime unlock.
How to automatically switch keyboard language per app on Mac?
Boomkey lets you pin a specific layout to a specific app, so your terminal can stay on English while your notes app opens in Ukrainian. You can also turn Boomkey off entirely for chosen apps — code editors and terminals are excluded out of the box.
