Having to switch typing modes countless times every day on computers and phones has long been a major annoyance for multilingual users. With the new Vikey application, author Tony Dinh claims to have completely resolved this inconvenience.

In a recent post on social network X, developer Tony Dinh (using the account @tdinh_me) officially introduced a completely new Vietnamese keyboard application called Vikey at the website address https://vikey.app.

Without hesitating to make a confident assertion, the author said that the new product he built is better than all keyboard applications currently on the market thanks to its ability to directly solve the problem of bilingual input that has been causing pain for many years.

According to Tony Dinh's share, people who only live and work in a single language environment will find it difficult to imagine the inconvenience of having to constantly switch keyboard typing modes countless times every day on both laptops and mobile phones.

For people who often have to communicate and work in both English and Vietnamese, pressing shortcuts to switch back and forth between the two input modes hundreds of times a day causes a major disruption in emotions as well as work performance.

This developer even called this the most annoying thing in his life before officially finding the solution by building Vikey himself.

The core difference that helps Vikey solve the problem lies in the mechanism of automatically switching between English and Vietnamese right while the user is typing, thereby completely eliminating the traditional manual mode switching operation.

According to data published by Tony Dinh, Vikey's ability to automatically identify and convert languages ​​reaches an accuracy of up to 99.73%. The author also frankly admits that this number cannot reach the absolute level because there still exist some linguistically impossible cases when placing key combinations next to each other.

Through the actual illustrative images and videos accompanying Tony Dinh's post, Vikey's installation interface is designed to be intuitive and neat. At the top of the application window, users are still provided with a button to switch between "Vietnamese" and "English" states, along with instructions to press the ⌥Z key combination to switch modes when necessary.

Below are detailed setup options including the "English/Vietnamese switch key" section assigned by default to ⌥Z and the switch to turn on or off the "Beep when switching" feature.

Most notable is the "Automatically switch" area located in the lower half of the interface with the option "For non-Vietnamese words, keep the key pressed" pre-activated, along with the option "Open Vikey when logging in" for users who want the application to automatically run in the background as soon as they turn on the device.

The true power of the feature "For non-Vietnamese words, keep the same typing key" has been clearly demonstrated through six situations of direct comparison between "Regular Percussion" and "Vikey" right on the "Message" window in the demonstration video.

In the first two situations, the test starts when the input device is in English mode (displaying the letter E icon in the right corner of the window) and the user types a sentence mixed from English to Vietnamese. When entering the phrase "I love pho", the normal keyboard, because it is in English mode, only outputs the raw character string "I love phowr" with a red spelling error underline under the word "phowr".

On the contrary, Vikey immediately recognizes the word "pho", automatically changes the status in the corner of the window to the letter V and accurately displays "I love pho".

Similarly, when a user types the sentence "thanks, thank you very much" from English mode, the normal keyboard leaves the accented characters as "thanks, thank you very much", while Vikey automatically switches to Vietnamese mode to smoothly turn the entire following sentence into "thanks, thank you very much".

The next four situations in the video focus on the most familiar obsession of Vietnamese users: being in Vietnamese typing mode (V symbol) but typing English words containing pairs of characters that match the Vietnamese punctuation rule. In the third example, when the user types the sentence "goodnight everyone", the two "o"s standing next to each other in the word "goodnight" are turned into the word "o" by regular typing, creating the misspelled word "goodnight everyone". With Vikey, the system automatically recognizes that "goodnight" is not a Vietnamese word, so it keeps the typed keys intact, while still removing the full mark for the phrase "everyone" behind it.

The same phenomenon also occurs in the fourth and fifth examples when users enter everyday communication sentences with English words inserted such as "happy birthday" and "order milk tea". Because they contain the character combinations "ir" and "or" which are the question mark keys in Vietnamese, normal percussion has deformed these two sentences into "happy birthday" and "milk tea".

In both cases, Vikey kept the English words "birthday" and "order" intact, while accurately processing the Vietnamese part with accompanying accents.

In the sixth situation, the difficulty is pushed higher when the user types the phrase "good morning everyone" while Vietnamese mode is on. Regular percussion immediately double-crosses both English words, turning good morning into "good morning everyone".

Meanwhile, Vikey automatically switches mode from V to E as soon as it recognizes the phrase "good morning" to restore the correct English text, then immediately switches back from E to V to continue typing the word "everyone" without the user needing to touch any conversion keys.

Closing his introduction, Tony Dinh invited the Vietnamese user community to directly download, experience Vikey and send feedback to help the application become more and more perfect.
