Flashcards.gg by Flashcards.gg

Add cards to your Flashcards.gg sets without leaving the page you are reading.

Select a word or a phrase, right-click and choose “Add to Flashcards.gg”. A small form opens right on the page: the selection is already the front and the set is the one you used last. Type the back, or press Auto to have it written for you, then save. The card appears in your set on every device where you use Flashcards.gg.

The extension talks only to flashcards.gg: the selected text is sent there when you press Save or Auto, and your API key is stored only in this browser. No analytics.

You need a Flashcards.gg account and a personal API key, which you create in your account at https://flashcards.gg/account/api-keys.
