Feature
VidNotes automatically generates flashcards from your video transcripts, turning passive watching into active learning. Each card captures a key concept, definition, or fact from the video, formatted as a question-and-answer pair ready for review. Whether you are preparing for an exam, learning a new skill, or reviewing a training session, flashcards help you retain information through spaced repetition without rewatching the entire video. For instance, a 50-minute organic chemistry lecture might yield 25-30 flashcards covering reaction mechanisms, definitions, and key distinctions the professor emphasized. The generation engine uses OpenAI models through AIProxy to identify extractable knowledge, prioritizing content with clear question-answer structure such as definitions, processes, comparisons, and factual statements over narrative or opinion-based content.
After transcribing a video, tap the flashcard option. The AI analyzes the content through the AIProcessingService, identifies key concepts, definitions, and facts, and generates question-answer pairs automatically. The engine focuses on extractable knowledge, meaning content that naturally maps to a question-and-answer format. A single transcript typically produces between 10 and 40 cards depending on the density of factual content in the video.
Browse through your generated cards, edit any that need refinement, and organize them into decks. Cards are stored locally as SwiftData FlashCard and FlashCardDeck entities so you can review them offline anytime. Each card maintains a link to the source transcript, so you can tap through to the original video context if a card's answer needs clarification beyond what the card itself provides.
Review your flashcard decks regularly. The question-answer format is designed for spaced repetition learning, helping you retain information over the long term. Active recall, the process of retrieving an answer from memory before seeing it, is one of the most evidence-backed study techniques. VidNotes cards are structured specifically to support this pattern, with questions that test understanding rather than simple recognition.
University students
Turn lecture recordings into exam-ready study cards automatically. Review key concepts during commutes or breaks without rewatching full lectures. A single semester's worth of recorded lectures can produce hundreds of organized flashcards, replacing hours of manual card creation with a few taps.
Language learners
Generate vocabulary and phrase cards from foreign-language video content for contextual, immersive learning. Because VidNotes preserves the original language, cards use the same phrasing and terminology you will encounter in real conversations, not textbook translations stripped of context.
Professional development
Convert training webinars and conference talks into reviewable knowledge cards you can revisit months later. Retain technical details from certification prep videos, compliance training, or industry talks without relying on your notes or rewatching the original recording.
The flashcard generation engine focuses on extractable knowledge, meaning concepts that have a clear question-answer structure. Definitions, processes, comparisons, and factual statements are prioritized over opinions or narrative content. The AI identifies when a speaker defines a term, explains a sequence of steps, contrasts two concepts, or states a measurable fact, and structures each of these into a card where the question tests recall and the answer provides the complete explanation. This selective approach means you get cards worth studying rather than a bulk dump of every sentence rephrased as a question.
Each flashcard deck is stored as a SwiftData FlashCardDeck entity containing individual FlashCard entities, all linked to the original VideoTranscript. This means you can always trace a card back to its source and watch the relevant section of the video for deeper context. The data model supports editing, reordering, and deleting individual cards without affecting the rest of the deck. Because everything is stored locally on-device, your flashcard library remains accessible without an internet connection and loads instantly.
VidNotes generates cards in the same language as the transcript. If you transcribe a Japanese lecture, your flashcards will be in Japanese, preserving the original terminology and phrasing that you will encounter in exams or professional settings. This is particularly valuable for language learners and students studying in a non-native language, where seeing the exact terms used by the instructor matters more than a translated equivalent. The language-aware generation uses the same prompt engineering system as summaries, with tailored instructions for each of the 20+ supported prompt languages.
