Most tools just dump a cleaned-up transcript into a document. LecturePDF actually understands and restructures the lecture content.
This means:
The result is notes that feel like they were written by a diligent study buddy who watched the entire lecture and prepared a full review document for you.
Any educational video with subtitles or a transcript works — university lectures, Khan Academy, Crash Course, tutorials, conference talks.

Your AI-generated study doc is ready in under 30 seconds. Read it online, export to PDF, or share with classmates.
The lecture is divided into logical sections, each with a summary and key takeaways.
Flowcharts, hierarchies, and comparison tables for complex ideas — rendered visually.
10 multiple-choice questions from the actual lecture. Great for active recall before exams.
Every technical term defined clearly. Alphabetically sorted for quick lookup.

One-click shareable link. Your classmates don't need an account to read it.
LecturePDF fetches the YouTube transcript and runs it through our document engine, which identifies chapters, key concepts, and term definitions, then generates diagrams, quiz questions, and a glossary — all in one pass.
Very accurate for factual content like STEM, history, and social sciences. The AI reads the actual transcript and doesn't invent facts. Diagrams are interpretive — they represent relationships described in the lecture.
They're best used as a supplement: watch the lecture for full context, then use the AI notes to review, find key concepts, and test yourself. Many students generate notes while watching, then review the document later.
Yes — code snippets, mathematical notation, and domain-specific terminology are handled well. Formulas mentioned verbally are included in the notes.
Currently notes are read-only inside LecturePDF. You can copy content from the document or export to PDF, then edit in any PDF editor or word processor.
