Turn a PDF into study guides, checked against your material
Upload a PDF and QuerySpark writes study guides from what is actually in it, so you can see the whole topic on one page on exactly what your course covers. PDF files up to 100 MB and 120 pages.
Example
Study guide from Cell Biology, Chapter 7
A sample of what you get from a PDF on biology. Yours is written from your own file.
Cell Biology, Chapter 7: Cellular Respiration
The three stages
- Glycolysis in the cytoplasm
- Krebs cycle in the matrix
- Oxidative phosphorylation on the inner membrane
Where the ATP comes from
- Substrate-level: 4 ATP
- Oxidative phosphorylation: about 26 to 28 ATP
Common exam traps
- Krebs turns twice per glucose
- Fermentation makes no extra ATP; it recycles NAD+
Check yourself
Why can muscle cells keep running glycolysis without oxygen, and what is the cost?
How we read PDFs
We split long PDFs into page batches and read them with Google Document AI, which keeps headings, paragraphs and tables in reading order. Scanned pages are run through OCR automatically, and every item keeps a page reference so you can check the passage it came from.
Get the best results
- Trim to the chapters your exam covers.
- Keep the figure captions. Many good questions come from them.
- If your lecturer posts slides as PDF, upload those too: they show what was emphasized.
What your study guides include
- A structured outline of the main topics in your material
- Key terms, learning objectives and common misconceptions
- Worked examples where your material has them
- Practice questions at the end of each section
How you study them
Read the guide to get the shape of the topic, then jump into practice from any section. The guide and the questions come from the same analysis, so they cover the same ground.
Best for: starting a new unit, condensing a long reading, the night before an exam.
Things that trip people up with PDFs
- Scanned textbooks with skewed pages can drop a few words. OCR handles most of it, but a clean scan gives cleaner questions.
- Two-column journal layouts sometimes interleave columns in cheaper tools. We keep layout order, so questions stay coherent.
- Huge PDFs dilute focus. Upload the chapters on your exam rather than the whole 600-page book.
Questions about pdf to study guide
Does it work with scanned PDFs?+
Yes. Scanned pages are detected and run through OCR before questions are written. Clean, straight scans give the best results.
How long can the PDF be?+
Up to 100 MB and 120 pages per upload. For a long textbook, upload the chapters your exam covers so every question is relevant.
How long is the study guide?+
Choose a quick review sheet, a comprehensive guide or an exam-prep guide. Length follows your material: a ten-page chapter gets a page or two, not padding.
Is the pdf to study guide converter free?+
Yes. You can try it free with a 3-day Pro trial and no credit card, then keep using the free plan every month.
