Every field has a wall of vocabulary you're expected to absorb by osmosis. Econ has utility, elasticity, and Pareto efficiency. Bio has homeostasis, allele, phenotype. By week four your notes are a mess of half-remembered definitions and you quietly nod along in lectures pretending you know what "heteroskedasticity" means.
The new AI Glossary Builder in iTutor fixes that in one click. Upload your course material, click generate, and you get a full searchable A-Z glossary of every technical term in the document — defined in the context of your course, not a generic dictionary.
What each glossary entry includes
- Contextual definition — how your material uses the term, not how Wikipedia does
- First mention — the chapter and page where the term appears
- Example from the material — a real sentence from your PDF
- Related terms — so you can follow connections across concepts
- Translations — optional Arabic/English pair for bilingual students
It's an A-Z index rail, a search bar, jump-to-term anchors, and print-as-reference-booklet — basically the textbook's back-matter glossary, except it actually exists for every book you upload, even the ones that came without one.
Why this is different from flashcards
Flashcards are a drill tool. A glossary is a reference document. You keep a glossary open next to your textbook while reading, the same way a translator keeps a dictionary open. The two complement each other: build the glossary first so you stop drowning in unknown vocabulary, then generate flashcards from the terms that actually matter for your exam.
Also different from generic AI: every entry is grounded in your PDF with real citations. When the definition says "p. 47", there actually is a page 47 you can go verify.
Who benefits most
Med students. Law students. ESL learners studying in a second language. Anyone in a jargon-heavy field. Teachers building handouts for students who are new to the subject. Translators working through technical documents.
It stacks well with the Concept Explainer (which gives you a 6-tab deep dive on one concept at a time) and the AI Study Guide (which uses the same terms in its key-terms section). Glossary for quick lookups, concept explainer when you actually need to understand something in depth.
