Lecture Lens turns lecture slides into a study kit students can trust: a bilingual Thai–English summary, a practice quiz, and flashcards, where every answer links back to the exact slide it came from. The problem: at Chulalongkorn University, lectures mix Thai and English and slide decks run 60+ pages. AI summarizers save time but invent facts, and students can't tell which generated questions are actually covered in their course material. How it works: - Upload a lecture PDF. It is split into chunks and Muse Spark 1.3 (Meta Model API, Files API + Responses API) reads every page in parallel, including tables, formulas and diagrams. - A structured summary in Thai and English follows the lecture's own order, with a key-term glossary. Technical terms stay in English, the way students use them in class. - Every quiz question and flashcard must cite a source page and quote the slide verbatim. The app then verifies that the quote really appears on that page, and shows verified items first (15/15 flashcards verified on a 68-page Decision Tree lecture). - Click any page number to open the original slide beside the answer. Built with FastAPI, Pydantic-validated JSON outputs with automatic retries, and a vanilla JS frontend polished with Muse Code.
