StudyHub: AI Study Courses

Master any material — all the way.

StudyHub turns what you already have — lecture PDFs, slides, a recorded class, a YouTube link, or just a topic you name — into a real course. It splits the material into topics and takes every topic through three steps.

① UNDERSTAND
A summary of the topic, a glossary, a mind map, an infographic, a podcast-style audio recap for the way to class.

② CHECK YOURSELF
Flashcards in six formats with spaced repetition. Quizzes with seven question types. Before each answer you mark how sure you are — and that changes the review you get.

③ CLOSE THE GAPS
The quiz shows exactly where the gap is. StudyHub then works on that gap instead of repeating the whole topic: a 15-minute voice session, a chat tutor, extra cards, a focused note.

WHAT'S INSIDE
• Auto summaries from PDFs, documents, slides, images, audio, video, YouTube and web pages
• Flashcards with SM-2 / FSRS spaced repetition and four-button rating
• Quizzes with seven question types, confidence rating and instant explanations
• An AI tutor that answers from YOUR materials and cites the exact fragment
• A voice tutor you can talk a topic through with, out loud
• Lecture recording with speaker separation and automatic notes
• Audio recaps in four formats, one voice or two
• Essay grading with inline annotations and a PDF report
• Visual explainer for graphs, formulas and handwritten problems
• An automatic glossary of terms drawn from your own material
• A study plan and calendar that rebuild themselves around your deadlines
• Ready-made programmes: SAT, AP, A-Level, GCSE, Abitur, Bac, IELTS, TOEFL and more
• Works offline — materials, notes and cards stay on the device

WHY THREE STEPS
Rereading and highlighting are the most popular and the weakest ways to study. This method is built on retrieval practice and spaced repetition — the two techniques that score highest in learning-science reviews. The research and the references are on study.iec.exchange/method

EVERY ANSWER HAS A SOURCE
The tutor and the summaries link back to the exact fragment they came from. You can always check where an answer came from — and that is the point.
