lrnos

lrnos is an AI-powered learning operating system that turns the study materials you already have into an organized, adaptive study path. Upload PDFs, slides, Word documents, spreadsheets, images, audio, video, web articles, or YouTube links, and let it do the heavy lifting of structuring your learning.

Instead of leaving you to untangle dense notes on your own, lrnos automatically reads your content and maps out every concept in a logical order, so you always know what to learn next and why it matters.

Each day, you get a clear learning plan built around spaced practice, along with customized quizzes that target exactly what you need to review. A star-based mastery tracking system shows your progress at a glance, helping you retain information longer and prepare for exams efficiently.
