StudySim turns PDFs, notes, slides, lecture audio and video, or public YouTube links into flashcards called Notecards, practice quizzes, structured study guides, and two-speaker podcasts for exam preparation. Users can create a study space for each class, unit, or exam, add up to 15 sources, and generate study materials from the same content. Supported formats include PDF with OCR, DOCX, TXT, Markdown, PPTX, MP3, WAV, OGG, MP4, and WebM. A free preview is available, while StudySim Pro unlocks full generation. Each study space keeps related course materials and generated study tools together for review.
