Ravenote

Ravenote is a Chrome extension that turns passive watching into actual learning: • Auto-captures the transcript from Udemy + YouTube (no copy-paste) • Generates structured notes with key terms bolded + "Key Takeaways" • Extracts the core concepts from each lecture into a spaced-repetition system (SM-2) that quizzes you days later on what you were about to forget • Optional "active" mode: when you rewind a section, it offers a clearer explanation unprompted
