A general chatbot answers from everything it read on the internet, so it can sound confident and still be wrong about your course. Bo only uses the lectures and readings you upload, and shows the page behind every answer. When something is not in your material, it says so instead of making something up — you are never unknowingly studying from invented facts.
Built for your course. Not the whole internet.
ChatGPT, Gemini, and Claude are brilliant generalists. But for exam prep they answer from the open web, forget your progress, and hand you text. StudyPDF is built around your own course.

The difference
Why does a general chatbot fall short?
ChatGPT, Gemini, and Claude give you text in a chat. Bo gives you flashcards you can rate and send to Anki, graded mock exams, cheat sheets, mind maps, and study guides, all built from your own material and ready to use.
A new chat starts from nothing. Bo keeps a map of your whole course and tracks which concepts you keep missing. Scores fade as you master them, so what slipped recently rises to the top. Quiz answers feed mastery. Mastery drives what to study next. The loop tightens every session, all the way to the exam.

FAQ
Questions, answered.
You can, and it is great for quick general questions. But it answers from the open web, not your lecture, so it can be confidently wrong and can't point you to the page. It also forgets everything between chats. StudyPDF works only from your course, cites the page, builds the study tools, and remembers what you keep getting wrong.
StudyPDF uses strong language models under the hood, the same class of technology. The difference is everything around them: your course is read and mapped, answers are grounded in it with citations, and your progress is tracked. The model is the engine, not the product.
Build flashcards you can rate and export to Anki, write timed graded practice exams in your professor's style, generate cheat sheets and mind maps from your notes, cite the page behind every claim, and track per-concept mastery across your whole course so it knows what to study next.
Yes. Bo answers from the lectures, slides, and readings you upload. When something is not in your material, it tells you instead of inventing an answer, so you are never studying from made-up content.
