This project, the Smart Vocabulary Builder, presents a full-stack, AI-powered web application designed to overcome these challenges by creating a highly efficient, personalized, and interactive learning environment. The system is architected with a robust Python-based FastAPI backend, a dynamic React.js frontend, and leverages a database managed by SQLAlchemy. At its core, the application implements a Spaced Repetition System (SRS), utilizing a priority queue to intelligently schedule word reviews at optimal intervals, thus combating the natural forgetting curve. Innovation within the project is driven by the deep integration of the Google Gemini API, which transforms the learning process into a conversational experience. When a user adds a new word, the application initiates an \"AI Consultation,\" providing not just a definition, but also a contextual example sentence and a creative mnemonic. This interaction is dynamic, allowing users to regenerate explanations if clarity is not achieved. The platform further personalizes the learning journey by proactively suggesting new, relevant words based on the user's existing vocabulary. A key feature is the integrated, browser-native \"Listen & Practice\" tool, which combines text-to-speech and speechto-text functionalities for pronunciation feedback without reliance on costly external services. The result is a feature-complete, intelligent learning platform that successfully merges fundamental computer science algorithms, modern full-stack development practices, and the power of generative AI to offer a demonstrably more effective and engaging alternative to conventional vocabulary-building methods.  \nKeywords: Artificial Intelligence, Spaced Repetition System, Vocabulary Learning, Generative AI, Personalized Learning, FastAPI, React.js, Natural Language Processing.  \nI. INTRODUCTION  \nVocabulary acquisition is a critical component of language proficiency, directly influencing reading comprehension, writing ability, and effective communication. Despite its importance, traditional vocabulary learning approaches—such as rote memorization and static dictionary usage—remain inefficient, often leading to rapid forgetting and limited contextual understanding. These methods fail to incorporate cognitive principles of memory retention and do not support active recall or personalized learning, resulting in suboptimal outcomes for learners. Recent advancements in intelligent learning systems have introduced adaptive techniques to address these limitations. In particular, Spaced Repetition Systems (SRS) have been widely recognized for their ability to enhance long-term memory retention by scheduling reviews at optimal intervals based on user performance. Concurrently, the emergence of Generative Artificial Intelligence has enabled the dynamic generation of contextual content, including definitions, example sentences, and mnemonic aids, thereby improving ","cbCaig3ZQJqpRBTK","https://ap.wps.com/l/cbCaig3ZQJqpRBTK","pdf",1004277,"English","# I.
