Here's the translation: 【From a Cornell University Startup Team — The AI GSAT Vocabulary Partner That Truly Gets You】 Let's be honest — traditional vocabulary books and flashcards have no way of verifying whether you've actually retained the words. Kernel Vocab, developed by a Cornell University startup team and designed specifically for GSAT test-takers, combines cutting-edge behavioral science with AI algorithms to permanently break the vicious cycle of memorizing and forgetting. Core Features: ● Proprietary MSRS Memory Engine: This isn't your ordinary flashcard app! Our pioneering multi-modal memory algorithm cross-tests you through a variety of formats — flashcards, multiple choice, cloze exercises, and more. It precisely predicts your brain's "forgetting curve," automatically skips words you already know, and zeroes in on your exact memory weak spots to maximize review efficiency. ● Real Exam Practice: Still going through words alphabetically two weeks before the test? Kernel lets you switch strategies in one tap based on your prep timeline, and generates questions using real past GSAT exam contexts. Every word you study and every sentence you read is an actual tested point from real exams. ● Pet Companions & Community Motivation: Instead of white-knuckling your way through study sessions, open the app because you can't bear to let your pet go hungry! Through gamification mechanics and peer community dynamics, you'll stick with it "painlessly" all the way to exam day — building a powerful habit of daily automatic learning. Your GSAT prep starts with Kernel. Contact Us: Website: https://kerneltech.app Support: hello@kerneltech.app
