Visit KnowtSeparate reading from remembering
Reading tools optimize typography, navigation, and attention. Study tools optimize retrieval practice and review. Converting a textbook to EPUB may improve the hours spent reading, while spaced repetition helps retain a smaller set of ideas afterward.
AI tools are strongest when answers remain grounded in assigned sources and students verify claims against the original material. Keep page-citable PDFs for coursework even if you read from a more comfortable EPUB copy.
A simple workflow for a PDF-heavy course
Keep the official files in a course folder or Zotero. Convert only long text-first readings to EPUB. Capture concise notes while reading, then turn genuinely testable ideas into flashcards. Use AI to explain or compare passages, not as a substitute for checking the source.
