Due to the fact that this is an unofficial client which use the regular DeepL API, you need a own API Key.

DEEPL API FREE is already sufficient and provides a 500,000 character limit per month at no cost, which should be enough for personal use.


Limited feature set and just a simple optic compared to the official Windows or Mac App.

jDeepL supports the Free and Pro Version of the DeepL API, the correct API URL will be picked automatically based on the entered API Key.

The Shortcut CTRL + C + C, similar to the DeepL Windows App, will: * Copy the selected text * Restore the jDeepL Window if it's minimized or not in Focus * Paste the earlier copied text * Trigger the Translation
