Guide
Use a clearer review method for charts, diagrams, scanned slides, and pages where text extraction alone is not enough.
Slides with diagrams, screenshots, handwritten annotations, or scanned pages often break traditional ways of studying PDFs because plain text extraction misses what actually matters.
Students then either ignore the page or open a separate AI chat with no shared context.
Keep the page in view, capture a short note about what the visual is trying to show, and use AI explanations only for the unclear part of the image or logic.
This is where OCR and image-supported analysis become more useful, because they help recover meaning from slides that are not text-friendly.
This guide is most relevant for science, engineering, medicine, economics, and business lectures where charts and diagrams do a lot of the teaching work.
If your weak points cluster around visually dense pages, a page-aware review setup usually works better than generic PDF summarization.
Keep exploring the guides and study flows that fit the way you review lecture materials.
