PDF to Flashcards in Seconds
Upload your PDF and get AI-generated flashcards plus practice quizzes from the same document. Works with lecture slides, textbook chapters, manuals, and any text-based PDF. Bilingual.
No credit card. Upload a PDF and try it now.
Manual flashcards take hours. Your PDF is already there.
A 30-page chapter has roughly 60 to 100 testable concepts. Typing those into a flashcard app one by one takes 2 to 4 hours of pure setup time before you have even started studying. By the time the deck is done, your motivation is gone and your exam is closer.
StudyBuddy reads the PDF, identifies the testable concepts, and produces flashcards plus practice quizzes in under a minute. The same upload powers three different study modes from one file.
How it works
1. Upload your PDF
Lecture slides, textbook chapters, exam review guides, manuals, research papers, instructor handouts. Any text-based PDF up to 50,000 characters (about 20 pages). Longer documents split automatically by topic, giving you separate progress tracking per topic instead of one giant mixed deck. Word documents, PowerPoint files, and plain text are also supported.
2. AI generates flashcards plus quizzes
In under a minute, you get three things from the same upload: a flashcard deck for memorization (definitions, terms, formulas, named processes), multiple-choice practice quizzes for active recall, and an exam mode that simulates timed test conditions. The AI focuses on what is likely to appear on assessments, not random sentences pulled from the text.
3. Study with the mode that fits the task
Use flashcards for fast review and memorization. Use MCQ practice when you want feedback on why specific wrong answers are wrong. Use exam mode for timed simulations before a real test. All three work from the same source material, so switching between them is friction-free.
What makes StudyBuddy different
One upload, three study modes
Most PDF-to-flashcards tools give you only flashcards. StudyBuddy generates flashcards plus multiple-choice quizzes plus exam-format simulations from the same upload. If you are studying for a test, you need more than just memorization cards; you need practice with the format the test uses.
Per-option feedback on every wrong MCQ answer
When you pick a wrong answer on a multiple-choice question, you do not just see why the correct option is correct. You see the targeted rationale for your specific choice: why that wrong option is wrong, with the factual correction. This is the feedback model UWorld is known for, and it is what builds real understanding instead of pattern matching. Per-option feedback is rare in PDF-to-flashcards tools at this price point.
Adaptive algorithm for MCQ practice
The MCQ practice mode uses an adaptive algorithm that combines several systems working together: spaced repetition with forgetting curve modeling to time your reviews before you would forget, difficulty adjustment along Bloom's Taxonomy cognitive levels so questions get harder as you improve, and interleaving that mixes topics to prevent fatigue on a single area. The result: you spend less time on what you already know and more on what you need.
Independent tracking per document
Each document keeps its own analytics. Cardiology in your cardiology textbook does not blur into cardiology in your pharmacology notes. Your weak spots are tracked per document, per topic, so you know exactly where to focus.
Bilingual native support
The AI detects the language of your PDF and generates flashcards, quizzes, and rationales in that same language. Spanish, Portuguese, French, German, and most major languages with full quality. If you study in two languages, this saves you the cognitive load of switching while learning.

If you already use a notes app like RemNote or Notion and want flashcards integrated there, RemNote is a good fit. If you want flashcards plus MCQ practice with detailed feedback from the same upload, StudyBuddy is built for that.
Common use cases
Pre-meds and medical students
Upload First Aid chapters, Pathoma sections, your professor's slides, or Sketchy notes. The AI generates flashcards for terminology and definitions, plus MCQs for clinical reasoning practice. For clinical material, the MCQs include a mix of recall, application, and full clinical vignettes.
Undergraduate exam prep
Upload your lecture slides or textbook chapters before a midterm or final. The AI generates the breadth you need for memorization plus the depth you need for the harder questions. Reset the flashcard deck the night before for one final pass.
Graduate students and certifications
Convert dense research papers, certification manuals, or regulatory documents into structured study material. Each document maintains its own tracking, so your statistics review does not blur into your methodology notes.
Language learners
Upload vocabulary lists, grammar guides, or reading passages in your target language. The AI generates flashcards in that language directly. For pairs (Spanish-English vocabulary, French-English phrases), upload bilingual documents and the AI produces matched cards.
Frequently asked questions
You upload a PDF and the AI reads it, identifies the testable concepts (definitions, relationships, formulas, key facts, named processes), and generates a set of flashcards with question on one side and answer on the other. The same upload also produces practice multiple-choice questions and exam-format quizzes. Processing time is under a minute for most documents. The character limit per document is 50,000 (about 20 pages); longer materials are split by topic, which gives you separate progress tracking per topic instead of one giant mixed deck.
PDF, Word documents (.docx), PowerPoint presentations (.pptx), and plain text files. For PDFs specifically, text-selectable PDFs work best because the AI reads the text directly. Scanned PDFs where the text is actually an image require OCR, which works but is less reliable for low-quality scans or handwritten material. If you have a scanned PDF and the results are mediocre, try running it through an OCR tool first to make the text selectable, then upload.
Yes. The AI detects the language of your PDF automatically and generates flashcards and quizzes in that same language: questions, answers, and per-option rationales on the MCQs. Spanish, Portuguese, French, German, and most major languages are supported with full quality. This is particularly useful if your study material is not in English (university courses outside the US, medical board prep in Spanish, language learning resources).
RemNote and Scholarly focus on flashcards specifically and integrate well with note-taking workflows. Quizlet is the most popular flashcard platform globally but the AI generation feature is limited. StudyBuddy is built around a different idea: one upload produces flashcards, multiple-choice quizzes with per-option feedback, and exam-format simulations, with an adaptive algorithm that adjusts to your performance. If you only want flashcards and already use a notes app, RemNote may fit your workflow better. If you want flashcards plus MCQ practice with detailed feedback, especially for exam prep, StudyBuddy is built for that.
The full adaptive algorithm applies to multiple-choice quizzes. It combines spaced repetition with forgetting curve modeling, difficulty adjustment based on cognitive levels from Bloom's Taxonomy, and interleaving to prevent fatigue on a single topic. Flashcards use a simpler system: each card is marked Known or Learning. Known cards leave the rotation; Learning cards keep appearing until you master them. You can reset the deck with one click to review everything before an exam. Two different systems for two different learning modes.
Yes. The free plan gives you 5 processing credits per month, which means 5 new documents per month. Once a document is processed, all study sessions on it are unlimited at no extra cost. There is also a guest mode where you can upload up to 6 documents without signing up, to try the experience before creating an account. For more documents per month, Pro is 9.99 USD per month (60 credits) and Premium is 24.99 USD per month (100 credits).
Not currently. StudyBuddy is built as its own study environment because the value comes from the integrated workflow: flashcards, MCQ quizzes with per-option feedback, exam mode, and the adaptive algorithm work together. Exporting just the flashcards to Anki strips the per-option feedback and the adaptive scheduling, which is most of the value. If exporting to Anki is critical for your workflow, tools like Scholarly and AnkiDecks are built around that export. If you want a complete study environment from the same upload, StudyBuddy keeps everything in one place.
