Language Learning, Reimagined. Learn a language efficiently by unlocking your memory’s innate ability to remember images and locations. Palazzo uses memory techniques based in neuroscience to help you easily memorize vast quantities of new vocabulary words and grammar concepts. Our unique method combines video-based “memory palaces” and mnemonic images to make learning fun, efficient, and permanent. Trials have proved that learning by this method dramatically improves test scores after even just a single use. In addition, users can choose the words and concepts that they want to study, making Palazzo easily compatible with any other study methods, including other apps or in-person classes. So whether you’re embarking on a self-taught language-learning journey, a student wanting to finish at the top of your class, an advanced speaker wanting to master a difficult tense, or you want to progress through the curriculum on another language-learning app faster and remember things better, Palazzo will help you harness the magic of visual learning to actually achieve your language-learning goals. Subscribers to Palazzo currently get access to: ◆Spanish◆ 2,000 vocabulary flashcards covering the most frequently used Spanish words, each equipped with audio, example sentences, and a unique image-based mnemonic to facilitate rapid vocabulary acquisition and retention. 17,000 verb conjugation flashcards (every conjugation for every verb within the top 1,000 most frequently used Spanish words) each equipped with audio, example sentences, and an image-based mnemonic from our verb conjugation video course. 13 animated video “memory palaces” full of characters which symbolize all of the difficult-to-remember verb conjugations for all major tenses. Our video course currently includes the following videos: • Present Tense AR Verbs • Present Tense ER Verbs • Present Tense IR Verbs • Preterite Tense AR Verbs • Preterite Tense ER and IR Verbs • Imperfect Tense AR Verbs • Imperfect Tense ER and IR Verbs • Future Tense AR, ER, and IR Verbs • Conditional Tense AR, ER, and IR Verbs • Subjunctive Mood AR Verbs • Subjunctive Mood ER and IR Verbs • Imperfect Subjunctive Mood AR, ER, and IR Verbs • Affirmative and Negative Imperative Mood AR, ER, and IR Verbs In addition, we are currently developing thousands more vocabulary and verb conjugation flashcards, as well as a Spanish grammar video course. ◆Other Languages◆ We are currently developing curricula for several other languages, and plan to release these as soon as possible, starting with French. * Thanks for checking us out. If you find these techniques to be powerful, please give us a rating in the app store and share Palazzo with your fellow language learners. This will help us generate more and better content. Enjoy the journey! * A note on our usage limits: we currently limit our daily flashcard interactions at 198 new cards + reviews per day for each user (99 vocabulary cards and 99 conjugation cards). Our spaced-repetition algorithm is designed to promote long-term memory retention, eliminating the need for cramming, and our studies show that exceeding this limit leads to rapid user review fatigue and language study abandonment. If you feel strongly that you would like to increase your review limit beyond that threshold, please contact us via the ‘report a problem’ link in the main menu and let us know your motivations for intensive study and we can increase this limit on an individual basis. Thanks for your understanding.
