What you can generate from your PDF
When you focus on the conversion of a PDF to flashcards + spaced repetition, you aren't just getting digital cards. You are building an ecosystem of study materials including:
Flashcards: Both terminology-based and concept-based cards.
Practice Quizzes: Multiple-choice questions to test your knowledge before the review cycle.
AI Tutor Support: A context-aware chatbot that knows your PDF inside and out.
Mini example: Photosynthesis Basics
Imagine you upload a 2-page PDF about the light-dependent reactions in plants.
Input: A technical PDF describing the role of chlorophyll, ATP, and the Calvin Cycle.
Output (Sample Flashcards):
Front: What is the primary pigment involved in photosynthesis? / Back: Chlorophyll.
Front: Where do the light-dependent reactions occur? / Back: Thylakoid membranes of the chloroplast.
Front: What are the two main products of the light reactions? / Back: ATP and NADPH.
Front: Define Photolysis. / Back: The decomposition or separation of molecules by the action of light.
Front: What cycle uses ATP and NADPH to convert CO2 into sugar? / Back: The Calvin Cycle.
Tips to get higher-quality results
Clean the PDF: Remove blank pages or unnecessary appendices before uploading to help the AI focus on core content.
Use Clear Headers: If you are creating the PDF from your own notes, use clear H1 and H2 tags to help the AI categorize topics.
Specify Context: Use the prompt settings to tell the AI if you are prepping for a medical exam versus a high school quiz.
Review the 'Trash': If the AI picks up page numbers or footer text as card content, simply delete those cards during the review phase.
Troubleshooting (common issues + fixes)
Issue: Scanned PDF text is garbled → Fix: Re-scan at a higher DPI or use a Clear Text PDF version if available.
Issue: Too many cards generated → Fix: Use the page range selector to process only the most important sections of your document.
Issue: Content feels too generic → Fix: Use the 'Refine' button to tell the AI to focus specifically on bolded terms or formulas.
Issue: Spaced repetition dates look wrong → Fix: Ensure you are rating your cards correctly (Easy/Medium/Hard) to reset the algorithm's timing.
