LearnX is an online study application that turns uploaded course notes into a structured exam preparation program. The primary function is to identify knowledge gaps before an exam by generating practice questions from the user's own material. The system is designed to target common misconceptions, easily confused terms, and counterintuitive facts. It uses answer choices that reflect common mistakes, and it favors retrieval practice, requiring learners to produce answers from memory rather than simply recognize a correct option. Questions are framed around realistic situations that ask learners to apply concepts, weigh trade-offs, and justify decisions. The typical workflow begins with uploading notes and selecting files for a sprint. A sprint window is set for a defined period, such as 15 days, and the application builds a study path with ordered units, focused sessions, and checkpoints. The dashboard displays the next unit, a countdown, and the review schedule. Missed concepts are returned as planned repair tasks instead of being buried in results. Social features include squads, friend activity, weekly XP, and shared study momentum. The same sprint can be resumed across desktop and mobile web. LearnX processes files automatically and anonymously. No human views the study materials, and files are not used for model training. Users can save their files for reuse or delete them at any time. All data is transferred over an encrypted connection. The service can be used without a credit card.
