Core Benefits

Spend less time doing more.
Studying flashcards is the most efficient way to learn vocabulary. Unfortunately creating and scheduling flashcards easily doubles or triples the time it takes to use them. Because language learners need to know around 10,000 words to understand native-level content, this overhead adds up to 100 or more hours of lost study time — Until now!

Lingjini builds and manages flashcards for you. Simply provide a word or phrase, and Lingjini will handle the rest, creating optimized flashcards for you. In addition, Lingjini's scheduling algorithm only shows you cards when you need to see them, so you don't waste time on inefficient studying. It's like having your very own dedicated tutor.

Learn words through native content.
Oftentimes, the simplest words have the most varied uses. Consider how the English word just has different meanings in the following phrases: the sun just came out (recently), the arrow just missed the mark (barely), and a just penalty (fair). Learning words by memorizing their various definitions is almost impossible.

Instead, vocabulary acquisition is best accomplished through the use of context such as simple sentences that reveal how words are used in relation to other words, and how these relationships change meaning. The process of finding and memorizing illustrative sentences is referred to as "sentence mining." Lingjini does this automatically.

Memorize meaning, not flashcards.
Although flashcards are the best way to learn vocabulary, they have one significant flaw. People regularly learn to memorize the flashcard rather than the word. This means that someone can have perfect recall studying their flashcards at home, but they can't recognize the word when it matters most: outside in the real world.

Lingjini addresses this problem by continuously changing the context around a target word or phrase. This captures the benefits of immersion by exposing learners to a variety of different contexts, oftentimes with their own shades of meaning.

The Research

Mastering a language requires hundreds of hours of dedicated study. Before investing your valuable time in a shiny new app or approach, you should see what language experts and academic research has to say about the various techniques Lingjini synthesizes.

  1. "Flash cards are the most underrated language-learning tool of all."
    Barry Farber in How to Learn Any Language (pg. 58)
  2. "Learning from [flash] cards is a way of quickly increasing vocabulary size through focused intentional learning."
    Paul Nation in Learning Vocabulary in Another Language (pg. 445)
  3. "Research also shows that flash card learning is not only common but also effective and efficient. Studies demonstrate that memory...may persist over years if reviewed regularly...[and flash card study] improves L2 learners’ ability to use the words in communication."
    Tatsuya Nakata in The Routledge Handbook of Vocabulary Studies (pg. 304)

  1. "...digital flashcards were more effective at increasing immediate vocabulary gains than paper flashcards for basic and intermediate-level students."
    Robert Ashcroft et. al in Digital flashcard L2 Vocabulary learning out-performs traditional flashcards at lower proficiency levels (pg. 26)
  2. "This research suggests that paper and digital flashcards are equally viable options for students but platform matters. Mobile technologies like tablets might be especially advantageous."
    Kara Sage et. al in Flip, Slide, or Swipe? Learning Outcomes from Paper, Computer, and Tablet Flashcards (pg. 461)
  3. "...the participants in the experimental group who used mobile applications outperformed the control group (paper flashcards) in the post-tests, and the effect size of the observed differences was very large."
    Ismail Xodabande et. al in Self-directed learning of core vocabulary in English by EFL learners: comparing the outcomes from paper and mobile application flashcards (pg. 93)

  1. "SRSs are flash cards on steroids."
    Galbriel Wyner in Fluent Forever: How to Learn Any Language Fast and Never Forget It (pg. 11)
  2. "The expanding pattern may thus be seen as an effective shaping procedure for successively approximating the desired behavior of unaided recall at long delays."
    T.K. Landauer and Murray Hill in Optimum Rehearsal Patterns and Name Learning (pg. 631)
  3. "The present results suggest that the spacing effect and not mere repetition of trials alone is contributing to the gains observed in the adjusted spaced retrieval group. Our results, among others, imply that expanding retrieval practice is most advantageous in comparison to other training schedules."
    Hawley et. al in A comparison of adjusted spaced retrieval versus a uniform expanded retrieval schedule for learning a name-face association in older adults with probable Alzheimer's disease (pg. 648)
  4. "We replicated the experiment that yielded the famous forgetting curve describing forgetting over intervals ranging from 20 minutes to 31 days. Ebbinghaus' goal was to find the lawful relation between retention and time-since-learning."
    Jaap M. J. Murre and Joeri Dros in Replication and Analysis of Ebbinghaus' Forgetting Curve (pg. 1)

  1. "...because a sentence context can provide extra information and little effort is required to add a sentence context to word cards, it is probably advisable to use such contexts on cards wherever possible."
    Paul Nation in Learning Vocabulary in Another Language (pg. 461)
  2. "You'll learn fastest if you take advantage of...simple, clear sentences with translations and explanations."
    Galbriel Wyner in Fluent Forever: How to Learn Any Language Fast and Never Forget It (pg. 89)
  3. "Most people agree that vocabulary ought to be taught in context (Nilsen 1976; Chastain 1976; Rivers 1968). Words taught in isolation are generally not retained."
    Elliott L. Judd in Vocabulary Teaching and TESOL: A Need For Reevaluation of Existing Assumption (pg. 73)
  4. "Moreover, this method, unlike that of lists or words to be memorized, actually aids the memory in remembering general definitions. It seems reasonable to assume that if one can associate a context with a word, one has a greater chance of recalling the definition."
    Robert S. Burroughs in Vocabulary Study and Context, or How I Learned to Stop Worrying about Word Lists (pg. 55)

The Company

Lingjini is the creation of Rosenstare LLC, a software company by and for language learning enthusiasts. It was inspired by ongoing research in language acquisition, recent advances in generative language models, and lived experiences as language students in both classroom and independent study settings.

Lingjini is a play on the Swedish and Norwegian word språkgeni, meaning someone who has an aptitude for language. "Ling" refers to the Latin "lingua" for speech while "jini" references the magical wish-granting genie (or jinn). The name represents the dual mission of providing a magical experience while simultaneously helping students reach true mastery.
