Questions
HoverNotes vs NotebookLM — common questions
Is HoverNotes better than NotebookLM?+
It depends on the job. For taking notes while you actually watch a video, HoverNotes is purpose-built: it follows the footage in real time across YouTube, Udemy, Coursera and virtually any other video playing in your browser, captures timestamped screenshots of on-screen code, equations and diagrams, and saves structured notes to your Obsidian vault. NotebookLM is the stronger choice if you want to upload documents and sources into a notebook and have Gemini synthesize, summarize and answer questions across them.
What is the difference between HoverNotes and NotebookLM?+
NotebookLM is a source-grounded research assistant: you upload sources (PDFs, docs, websites, YouTube links, audio) into a notebook — up to 50 per notebook on the free tier — and chat with them, generate Audio and Video Overviews, study guides, mind maps and reports, all powered by Gemini. HoverNotes is a live note-taker that watches videos with you as you learn, captures screenshots of code and diagrams the moment they appear, and writes timestamped notes straight to a local Obsidian vault.
Does NotebookLM take notes while you watch a video?+
No. NotebookLM can accept a YouTube link as a source and work from its transcript, but it does not watch alongside you or capture the visual frames — so on-screen code, equations and diagrams that never appear in the transcript are lost. HoverNotes follows the video in real time and captures timestamped screenshots of exactly those moments, then turns them into structured notes.
Is HoverNotes cheaper than NotebookLM?+
NotebookLM has a capable free tier, with higher limits available through Google AI Plus, Pro and Ultra plans (and Google Workspace / Cloud for organizations). HoverNotes is also free to install, with paid plans for heavier use. The bigger difference is privacy: HoverNotes stores your notes locally in your own Obsidian vault, while NotebookLM keeps your notebooks in Google's cloud.
Who should use NotebookLM instead of HoverNotes?+
Choose NotebookLM if your main goal is research across a collection of documents — synthesizing PDFs, papers and reports, asking grounded questions with citations, or generating Audio Overviews and study guides from sources you upload. Choose HoverNotes if you learn from video and want a lasting, screenshot-rich note library built automatically as you watch.
