How these study packs are made
From open textbooks
Each pack is built from a free, openly licensed textbook (LibreTexts, OpenStax, Pressbooks). The text is split into chapters and passages, so every answer in the tutor chat cites the passage it came from.
Flashcards and quizzes
Key terms, definitions and worked examples become flashcards. Definition questions become quizzes and practice tests. No AI model writes them, so nothing is invented.
Honest about quality
The study aids are generated automatically and marked Draft until a person reviews them. They can contain mistakes, so check anything important against your own textbook and instructor.
Licence and credit
Every pack names the book and its authors, shows the licence (Creative Commons), links to the original and says it was adapted. StudyGrasp stays free.
