Naver Papago

Naver Papago (Hangul: 네이버 파파고), shortened to Papago and stylized as papago, is a multilingual machine translation cloud service provided by Naver Corporation. Unlike other translators, Papago uses a neural machine to learn from its mistakes and learn what type of translations the user requires. The word "Papago" comes from the Esperanto word for "parrot", Esperanto being a constructed language.
Features.
Papago exited its trial phase and officially launched on July 19, 2017 with translation options for Korean, Japanese, Chinese, English, Spanish, and French. It was only available as a smartphone app but it has since launched its own website and has expanded to other languages.
From November 2019, Papago was changed to be available without Internet service. 
In 2020, the image translation function was introduced, and text in photos can be translated directly. It supports a total of six languages, including Korean, English, Japanese, Chinese, Vietnamese, and Thai.
Special function.
WSD screen.
If a homonym is detected in a sentence to be translated, the corresponding word is underlined in the Translation Results tab via the Word Sense Disposition (WSD) function. Click on the word to display a picture that expresses various meanings in simple shapes, and by choosing the correct shapes, you can get more accurate and correct translation results. This function seems to be able to solve the chronic problem in machine translation, the processing of Chinese words, but there are many cases where the data are not underlined due to the lack of them.
Automatic conversion of exchange rate.
Using real-time exchange rate information, the current exchange rate is calculated along with the translation result.
Global conversation.
It can be used even when it is not connected to the network. All four languages are available, and you can see the original text and how to read the frequently used essential phrases depending on the situation.
Push-to-talk.
This technology allows voice recognition even in noisy environments.
Supported languages.
The following languages are supported in Naver Papago.
