Video Highlight vs NotebookLM
NotebookLM is a research notebook over many kinds of sources, and for a YouTube video it works from the transcript text. Video Highlight is built around the video itself: the player sits beside your notes, and every point opens the video at its time.
NotebookLM is Google's research notebook. You add PDFs, Google Docs and Slides, web pages, audio files and YouTube videos as sources, ask questions across them, and make Audio Overviews, reports, flashcards and mind maps. It is free with a Google account, and Google AI plans raise the limits. When your sources are mixed, it is the right tool. When a YouTube video is the source, it imports the video's text transcript.

Video Highlight vs NotebookLM: FAQs
Does NotebookLM look at what is on screen in a YouTube video?
Google's help says that for a YouTube source only the text transcript of the video is imported, and the video needs captions. Text on a slide or code on screen that nobody reads out is not part of that source. In Video Highlight, Deep Watch watches the whole video for you. It looks at what is on screen and reads what is said, and keeps the key points with pictures of the screen. Deep Watch is included in Plus, Pro and Business.
Can I use NotebookLM and Video Highlight together?
Yes. One way to split the work: NotebookLM for a pack of readings and Video Highlight for the videos. Export a video's summary or transcript from Video Highlight as PDF, Word or Markdown, and add the file to a notebook as a source next to your PDFs and web pages.
Is NotebookLM free?
Yes. Google lets you sign up at no charge with a Google account, and Google AI plans or a qualifying Workspace license raise the limits. Video Highlight also has a Free plan: Summary, Transcript, Highlights and Ask on YouTube, Vimeo and Dailymotion links. Deep Watch, Private files and the paid exports are on Plus, Pro and Business. See pricing for the current plans.
Which is better for a long online course or a recorded lesson?
It depends on what the course gives you. If it is mostly readings with a few videos, one NotebookLM notebook with all of it is simpler. If the lesson is the video, Video Highlight lets you read the summary first, follow the transcript beside the player and jump to the exact second. You can upload your own lesson recordings as Private files on paid plans.
YouTube has its own Ask button. How is that different?
YouTube's help describes Ask YouTube on the watch page: signed-in viewers can ask questions about the video they are watching, on select videos and in select languages and regions. It works inside YouTube while you watch. Video Highlight keeps each video in your library with its Summary, Transcript, Highlights and Ask, and Ask answers carry times that move the player.
Does Video Highlight make Audio Overviews or flashcards?
No. Video Highlight makes summaries, transcripts, highlights and notes with pictures of the screen, and answers questions about a video. If you want a spoken overview of your sources or flashcards for revision, NotebookLM is the better choice.
Hours of video. Minutes of reading.
Researchers, professionals, and creators use it on YouTube videos and on their own recordings
