Yes. If you want a tool built around your whole course, with answers cited to the page, full graded exams, exports to Anki, PDF, and Word, mind maps and cheat sheets, and per-concept progress tracking, StudyPDF goes deeper. Both are free to start and both turn your uploads into flashcards and quizzes. Penseum adds a real-time voice tutor and a chat tutor, while StudyPDF focuses on grounding and tracking your own course material.
It cites the exact page, second, or source behind every answer and refuses to make things up, maps your whole course into one connected concept graph, writes full graded practice exams with sections, a timer, and a pass mark, builds mind maps and cheat sheets, exports to Anki, PDF, and Word, and tracks per-concept mastery so it knows what to study next.
Penseum has a real-time voice tutor that draws diagrams and marks mistakes in your handwritten work, runs an Exam Cram mode with timed mock exams, and has a 24/7 chat tutor with step-by-step solutions. StudyPDF studies the files you upload plus YouTube links.
It is free to start, and the free tier gives you about 4 materials a week. Pro and Ultra add a bigger weekly pool of credits for heavier exam-season use. You only upgrade when you outgrow the free plan.
