FlipWord makes language learning a passive experience by slowly introducing vocabulary to the user in-line in-context on any web page they visit, across desktop and mobile platforms. Upon encountering a flipped word, hovering over it will automatically show the native word that was replaced and speak the foreign word.

Progression through the language is independently determined for each word. Words are automatically selected and replaced in page content without any user effort. Occasionally a small quiz will be shown to the user instead of a flipped word. This is either a multi-choice flashcard, typing, or speech quiz. The progression is automatically determined by a hybrid passive/active spaced repetition algorithm.

FlipWord works across any language pair, but currently is best with English to Chinese and Chinese to English. For now, building each set requires some translation work. The current focus is to make one set work really well, and expand when it is time.

Moving forward, FlipWord is one piece of the puzzle. The goal is to make a completely individualized learning platform that works throughout a user's life, and to persist knowledge over time. It is currently in the desktop browser, with prototypes for mobile, but will be integrated into other daily routines such as texting and email. The platform itself will have more active components available for when a user actually wants to study, all of which will sync back to the same profile of the user to optimize learning.

FlipWord currently is focused on foreign languages, but could easily replace any flashcard-based system. Some examples we have prototyped are improving a user’s native vocabulary by replacing common words on a page with SAT level words and inserting extra content such as history facts.
