Learnex is an AI-powered academic study platform. You upload lecture slides, PDFs, or notes, and Learnex automatically generates structured study trails, active recall flashcards, diagnostic quizzes, Socratic tutoring sessions, and timed mock exams—strictly grounded in your own course syllabus.

How does Learnex generate study materials from PDFs?

Our document parsing pipeline analyzes layout, headings, diagrams, and formulas. It uses Retrieval-Augmented Generation (RAG) to build active recall questions and explanations bound to your source text, preventing false hallucinations.

Yes. The Hiker plan is 100% free forever and includes 1 active subject, document processing, unlimited adaptive quizzes with mastery tracking, spaced flashcards, full-subject notes, and AI audio lessons. Explorer ($4.99/mo) unlocks unlimited subjects, Socratic tutoring, animated video lessons, and problem labs. Master ($7.99/mo) adds the Timed Exam Simulator and Exam Readiness Score. Students with verified academic domains (.edu, .ac.uk, .edu.pk, etc.) get 20% off all paid plans.

What file types are supported?

We support PDF lecture slides, textbook documents, scanned handwritten notes, and high-resolution PNG/JPEG images up to 50MB and 150 pages per document.

Does Learnex train AI models on my uploaded notes?

No. Your course notes, lecture slides, and personal assignments are processed in strict isolation solely to generate your own study aids. We never use student uploads to train foundational AI models.

How is Learnex different from Quizlet or Anki?

Quizlet relies on crowdsourced public sets that rarely match your university syllabus, and Anki requires hours of manual card formatting. Learnex automates the entire setup from your course PDFs while providing interactive problem labs and timed mock exams.

How long does it take to generate a study trail?

Most uploads are processed in 2 to 3 minutes. The AI organizes your material into sequential topics, generates practice quizzes, and prepares flashcard decks so you can begin studying immediately.
