We are working on a vocab study feature that we think is better than flashcards and better suited to the purpose and method of Lupa. Watch for an announcement in summer 2020.
Meanwhile, we have an experimental vocab export feature, that makes it easier to import your selected vocab for a story into some flashcard apps like Quizlet and Anki.
You can enable this feature in the app by visiting:
More > Settings > Experimental features
Then you'll find a new "Export vocab..." option in the story menu (three-dots menu), and also an extra icon at the top of the Vocab List page in the app.
When you select this option, we will send you an email with a text (tab-separated) document attachment with the words and definitions. You can import into Quizlet or import into Anki or copy-paste wherever you wish.
