I like that it is super easy to translate text, if you have selected some text, you can just hit copy twice, and it will automatically open DeepL with the text already translated. It uses your history of translation to determine which language to translate with, and it automatically switches them for me. For instance, I frequently work with Spanish and English, so if I select English text, it will translate into Spanish, but if I select Spanish text, it will automatically detect and translate to English. It really is a wonderful tool for me! It is also free to use.= with limited characters and editing.

As being a certified translator of two language pairs of both Simplified and Traditional Chinese, I'd reckon DeepL offers better machine translation in Simplified Chinese output than other free web applications. Surprisingly DeepL does Japanese machine translation and overall quality is beyond expectation, this is very unlikely provided for free, thanks to the generosity from DeepL.

The best feature I like about Deepl is the ability to translate the whole sentence rather than just word by word and switch words and get their acronym on the fly.
