PeekaTube vs Google NotebookLM
NotebookLM is Google's AI research assistant — not a YouTube extension, but a multi-source research platform. You add YouTube URLs alongside PDFs, Google Docs, and audio files, then interact with all of them as a unified knowledge base. It generates Audio Overviews (podcast-style discussions) and Video Overviews of your sources. The free tier is generous (50 sources per notebook, 25 audio overviews/day), with Plus at $19.99/month via Google One AI Premium. NotebookLM is built for deep, multi-document research — not quick video previews.

Why Choose PeekaTube Instead
NotebookLM requires you to leave YouTube, create a notebook, and add sources manually — a research workflow, not a quick-check tool. PeekaTube gives you instant summaries with comment analysis directly on YouTube in 7 seconds. For quick 'is this worth watching?' decisions, PeekaTube is dramatically faster. For deep multi-source research projects, NotebookLM shines — and PeekaTube's export feature makes it easy to feed summaries into NotebookLM when you need both.
The Verdict
NotebookLM is the most powerful option for deep, multi-source research — combining YouTube videos with PDFs, docs, and audio into a unified knowledge base. Choose PeekaTube for instant, in-context YouTube summaries without leaving the page. The two tools complement each other beautifully: use PeekaTube for quick triage, then export to NotebookLM for deep research.
