NotebookLM YouTube timestamps: citations vs chapters
Both tools can read a YouTube video and answer questions about it. They differ in how you get back to the moment in the video: NotebookLM cites lines of the imported transcript, while YouTube Collector builds a chapter list where each timecode seeks the player.
What NotebookLM imports
Google's help page (the product is branded Gemini Notebook now, though most people still search for NotebookLM) says the text transcript of the video is imported as a source. Answers carry inline citations linked to that transcript, and you can watch the video in an embedded player inside the notebook. The citation points you at the words, so finding the moment in the video is a manual step: read the cited line, then scrub the player until you hear it.
One real constraint worth knowing before you start: only public videos with captions, user-uploaded or auto-generated, can be imported. There's no video length cap unless the caption file goes over 500,000 words, and videos published in the last 72 hours may not be importable yet.
Side by side
| YouTube Collector | NotebookLM / Gemini Notebook | |
|---|---|---|
| AI summary with clickable timecodes | Chapter list; click a chapter and the in-app player jumps to that second | Inline citations into the transcript text; no clickable chapter outline that seeks the player |
| Videos with no captions | Transcribes the audio itself (billed as credits) | Not supported, captions required |
| Bulk playlist or channel import | Paste one playlist or channel URL, imports in batches (Pro and Creator tiers) | Sources are added by URL; no playlist or channel import documented. Free notebooks hold up to 50 sources |
| Search across everything you've saved | One search over titles, summaries and every word of every transcript | Chat with the sources inside one notebook |
| Repurpose into a blog post, thread or LinkedIn post | Built in | Not what it's built for |
| Community transcript cache | Searchable, shared across users | No |
| Price | Free tier, then paid plans | Free tier, higher limits on paid Google AI plans |
Choose NotebookLM if
Your sources are mixed (PDFs, docs, slides, a few videos) and you want one place to ask questions across all of them. It's free, it's very good at that, and the Audio Overview feature has no equivalent here. YouTube Collector only does video.
Also choose it if your videos all have captions and you're happy scrubbing to find a moment. You'd be paying us for navigation you don't need.
Choose YouTube Collector if
You work through video in bulk and keep coming back to specific minutes. A 90-minute interview becomes a chapter list you can skim in about ten seconds, and one click drops you at the bit you wanted. Podcasters and creators going back through their own catalogue tend to want this, plus the repurpose step at the end.
FAQ
Does NotebookLM give timestamps at all? Its citations link to the transcript text it imported, not to a timecode that moves the player. If you need a clickable chapter outline, that's the gap.
Can I keep using NotebookLM as well? Yes. Export a transcript or summary from YouTube Collector as markdown and add it to a notebook as a source. Plenty of people run both.
What if the video has no captions? NotebookLM can't import it. YouTube Collector transcribes the audio and charges credits for it, which is the case smaller channels and older uploads hit most.
Is there a free tier? Yes, a real one. Playlist and channel import sit on the paid tiers.
