Thank you (and the others who replied). It is even from Germany which already sounds good.

The free variant allows to translate up to 5000 letters. It does (if one is so inclined) to install small desktop utilities that allow to translate marked/highlighted text with a keyboard shortcut. It also shows alternative words if you click on a word in the translation.

I am for quite some time now totally sold on deepl.

DeepL is the best there is right now.

It's probably even better in translation quality than Google Translate.
