Use Case
Picture this: it is 11 PM before your organic chemistry midterm and you need to find the professor's explanation of nucleophilic substitution from three weeks ago. The lecture was two hours long. You have four other exams this week. Scrubbing through the recording at 2x speed still takes an hour, and you are not even sure which lecture it was. This is the reality for students who rely on recorded lectures without a way to search them. VidNotes solves this by converting lecture videos into searchable, timestamped transcripts with AI-generated summaries and flashcards. A 90-minute organic chemistry lecture becomes a searchable transcript in under 3 minutes. Instead of rewatching, you search. Instead of manual note-taking, you let the AI extract the key concepts. The result is a structured study guide from every lecture, available on iOS, web (app.vidnotes.app), and as a Chrome extension, with offline access and export to PDF, TXT, or Markdown for your favorite tools.
You miss key points while trying to take notes and listen simultaneously
VidNotes transcribes the entire lecture automatically using Whisper-powered AI, so you can focus on understanding during class and review the complete transcript afterward. Every word is captured with timestamps, meaning you never lose a definition, formula, or example because you were writing something else down.
Finding a specific explanation means scrubbing through hours of video
Search the transcript for any keyword and tap the timestamp to jump directly to that moment in the recording. Need to find every time the professor said 'equilibrium'? One search shows all occurrences with their exact positions in the lecture. No more guessing or skimming.
Creating study materials from recordings takes almost as long as the lecture itself
VidNotes auto-generates summaries and flashcards from the transcript using OpenAI. A one-hour lecture produces a concise summary and a deck of question-answer flashcards in under 30 seconds. You get exam-ready study materials immediately instead of spending hours creating them by hand.
Record the lecture on your phone, download the MP4 from your course platform (Canvas, Blackboard, Moodle), or paste the YouTube link if the lecture is published online. VidNotes accepts any video format and imports from iCloud, Google Drive, and Dropbox.
VidNotes processes the audio using Whisper AI for local files or the VidNavigator API for YouTube videos. A 60-minute lecture typically transcribes in 2-3 minutes for local files. For YouTube videos with existing captions, the transcript is ready in seconds with full timestamp alignment.
Tap to generate AI summaries for a quick overview of the lecture's key points, and flashcards for active recall practice. Use AI Chat to ask specific questions like 'What were the three conditions for equilibrium?' and get answers with citations to the exact moment in the lecture.
Study your flashcards on the bus, search transcripts the night before exams, and export summaries as PDFs to share with your study group. All data stays on your device via SwiftData, so you can review offline in the library, on the train, or anywhere without an internet connection.
University students deal with a unique challenge: high-density information delivered in long-form video that needs to be retained for exams and applied in assignments. Traditional note-taking forces a trade-off between listening and writing. Recording solves the capture problem but creates a review problem: nobody has time to rewatch every lecture. A typical full-time student sits through 15-20 hours of lectures per week. Even at 2x speed, reviewing all of that content takes 7-10 hours, leaving little time for actual studying, problem sets, or writing.
VidNotes eliminates this trade-off. The transcript captures everything that was said, the timestamps make it navigable, and the AI features transform raw content into structured study materials. A two-hour organic chemistry lecture becomes a searchable transcript, a one-page summary of key reactions, and a deck of 25-30 flashcards covering the terminology introduced in that session. What used to take an entire evening of manual transcription and card creation now takes about three minutes of processing time.
The flashcard generation is particularly valuable for exam preparation. Instead of spending hours creating Anki cards manually, VidNotes generates question-answer pairs from the transcript automatically. You can review them on your commute, edit any that need refinement, and focus your study time on understanding rather than transcribing. Students preparing for cumulative finals can generate flashcards from an entire semester of lectures and have a comprehensive review deck without having written a single card themselves.
The AI Chat feature adds another layer of utility. Instead of re-reading an entire transcript to find where the professor discussed a particular concept, you can ask a direct question and get a synthesized answer with references to the specific timestamps. This is especially useful when writing papers or completing problem sets that reference material from multiple lectures across the semester.
