Feature
VidNotes automatically generates flashcards from your video transcripts, turning passive watching into active learning. Each card captures a key concept, definition, or fact, formatted as a question-and-answer pair ready for review. Prepping for an exam, learning a new skill, or revisiting a training session? Flashcards help you retain the material through spaced repetition without rewatching the whole video. A 50-minute organic chemistry lecture might produce 25-30 cards covering reaction mechanisms, definitions, and the key distinctions the professor hammered on. The generator uses OpenAI models through AIProxy to spot extractable knowledge, prioritizing content with clear question-answer structure (definitions, processes, comparisons, factual statements) over narrative or opinion.
After transcribing a video, tap the flashcard option. The AI runs the content through the AIProcessingService, picks out key concepts, definitions, and facts, and builds question-answer pairs automatically. The engine focuses on extractable knowledge: content that naturally maps to a Q&A format. A single transcript usually produces 10 to 40 cards depending on how much factual content the video has.
Flip through your generated cards, edit any that need polishing, and organize them into decks. Cards live locally as SwiftData FlashCard and FlashCardDeck entities, so you can review them offline anytime. Each card keeps a link to the source transcript, so if an answer needs more context, you can tap through to the original video.
Review your decks regularly. The question-answer format is built for spaced repetition, helping you retain information long-term. Active recall, where you retrieve an answer from memory before seeing it, is one of the most evidence-backed study techniques out there. VidNotes cards are structured for this, with questions that test understanding instead of 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 semester's worth of recorded lectures can yield 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 keeps the original language, your cards use the same phrasing and terminology you'll hear in real conversations, not textbook translations stripped of context.
Professional development
Turn training webinars and conference talks into reviewable knowledge cards you can revisit months later. Hold on to technical details from certification prep, compliance training, or industry talks without relying on your notes or rewatching the original recording.
The generator focuses on extractable knowledge: concepts with a clear question-answer structure. Definitions, processes, comparisons, and factual statements get priority over opinions or narrative. The AI catches when a speaker defines a term, walks through steps, contrasts two concepts, or states a measurable fact, and turns each into a card where the question tests recall and the answer provides the full explanation. This selectivity means you get cards worth studying, not a bulk dump of every sentence rephrased as a question.
Each deck is stored as a SwiftData FlashCardDeck entity containing individual FlashCard entities, all linked back to the original VideoTranscript. You can always trace a card to its source and watch the relevant section for deeper context. The data model supports editing, reordering, and deleting individual cards without touching the rest of the deck. Everything's local, so your flashcard library works without an internet connection and loads instantly.
VidNotes generates cards in the same language as the transcript. Transcribe a Japanese lecture and your flashcards come back in Japanese, keeping the original terminology and phrasing you'll hit in exams or professional settings. This is huge for language learners and students working in a non-native language, where seeing the exact terms the instructor used 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.
