Most ai study tools answer from the open web. StudyPDF answers from your own material. You upload your course once, and Bo reads every lecture, slide deck, and reading. From then on you just ask. Bo replies with a citation like Lecture 4, p. 12, so you can check the source instead of trusting a guess.

The study engine
It doesn't just answer. It builds.
Most AI answers your prompt and forgets it. Bo turns your whole course into one connected map, then builds real study tools from it. Graded, cited, and yours to export.

Why StudyPDF
AI study tools that actually know your course
Bo can also build whatever you need to study. Ask it to turn your PDF or lecture into flashcards, and it pulls the key terms straight from your notes. Ask for practice exams, and Bo writes questions in the style your professor actually tests. It can go from pdf to mind map when you want to see how ideas connect, or act as an ai study guide generator when you need a clear walkthrough of a topic.
Everything stays grounded in what you uploaded. When Bo writes summaries or a cheat sheet, it draws only from your course, then points back to the page it came from. There is no made-up content and no generic textbook filler. The answer is your material, organized for the exam in front of you.
Bo remembers your whole course over time. It knows which topics you have covered, which ones you keep getting wrong, and where the lectures left gaps. That longitudinal memory is what turns a pile of PDFs into one study companion you can keep asking, week after week, all the way to the final.
FAQ
Questions, answered.
No. Bo only pulls from the lectures and notes you upload. Every answer includes a citation to the page it used, so you can open the source and verify in one tap. If your material does not cover the question, Bo tells you instead of inventing an answer.
PDFs, slide decks, scanned notes, and photos of a whiteboard or textbook page. Upload a single chapter or your whole course. Bo runs OCR on scans and keeps everything in one place so you can ask across all of it.
Yes. Ask in plain language, for example \'build me a 20-question exam on chapter 3\' or \'write a study guide for the midterm.\' Bo generates it from your uploads with citations, and you can open, edit, or ask Bo to regenerate.
Yes. StudyPDF runs in your browser on desktop and phone, and your courses stay in sync. Open Bo between classes to ask about the lecture you just left, or review flashcards on the way to the library.
For most students, yes. The free tier covers uploading your course, asking Bo, and generating the core study tools through a typical term. Upgrade to Pro or Ultra when you need higher limits, faster generation, or heavier exam seasons.
ChatGPT answers from the whole internet. Bo answers only from your course. That means fewer generic textbook answers and fewer made-up details. You get cited pages, memory of what you are weak on, and study tools built from the same material.
Yes. Bo tracks what you have practiced, what you got right, and what is slipping. It can nudge you to refresh weak spots and picks up where you left off next week or next semester, as long as the course is in your account.
