Abstract
Students today must work through large volumes of academic PDFs with little tooling to support effective learning. Passive reading remains the default approach for most learners, yet it consistently produces poor retention and demands excessive preparation time. This paper presents CogniLeapAI, a web-based platform designed to convert static PDF documents into a closed-loop adaptive learning system. AI requests are routed across four providers (Google Gemini, OpenRouter, LaoZhang, and Kie.ai) with intelligent fallback chains and user-configurable encrypted API keys. From any uploaded document, six study tool types can be generated: summaries, study guides, notes, flashcards, interactive quizzes, and node-based mind maps. Retention is managed through a four-layer SM-2 spaced-repetition framework (Absorb, Recognize, Retrieve, Mastered), with AI-adjusted review intervals, response-time-aware scheduling, post-session weakness scoring, and predictive retention forecasting. An Adaptive AI Study Agent handles exam-aware plan generation, produces weekly learning reports, and adjusts schedules in real-time based on per-topic card data and stuck-card detection. The backend runs on Next.js 15, React 19, and Supabase, with AES-256-GCM key storage, row-level security, and per-request cost tracking built in. Field testing showed measurable time savings in study material preparation, stronger learner engagement through active recall, and improved long-term retention relative to passive document reading.
