Nightspar saves words and phrases from your conversations as spaced-repetition flashcards, adding meanings, IPA pronunciation and audio. Muse can pull out the words you looked up and add them to your review deck so you practice them later.

Example request: "Save the Spanish words I asked about today as flashcards and quiz me on them tomorrow."
