Show HN: Translate foreign words and learn them as flashcards

I created this browser extension and mobile app to look up unfamiliar foreign words and learn them as flashcards on my mobile device.

There are multiple solutions to do that, but my itch was that all the solutions make it difficult to create a high-quality flashcard: - nouns have to be saved as singulars - verbs have to be saved as infinitives - each word has to have a description

Works well (at least for the Dutch language). I have created around 900 cards, primarily good out of the box.

What do you guys think about it?
