Power Tools for
Google NotebookLM

NotebookLM limits each notebook to 50 sources on the free plan (300 on Plus). NotebookLM Power solves this with Merge — combine 20, 50, or even 100+ YouTube videos and web pages into a single text source. Instead of using 100 source slots, you use just 1. All content is preserved with timestamps and source URLs. This effectively removes the source limit for most use cases.

Yes! This is exactly what NotebookLM Power was built for. Open any YouTube search page, channel, or playlist — the Feed tab shows all videos with checkboxes. Select 10, 50, or all of them, pick your notebook, and click Add. Done in seconds, not hours of copy-pasting URLs.

NotebookLM Power works with 25+ platforms including Google Search (15 locales), Google Scholar, Reddit, Hacker News, PubMed, arXiv, Medium, Substack, GitHub, Stack Overflow, X/Twitter, LinkedIn, Wikipedia, Perplexity AI, TED, Vimeo, and more. Plus any website — just open the page, click Add, and it goes straight to your notebook.

NotebookLM's native YouTube import often fails on videos without English captions or with auto-generated subtitles in other languages. NotebookLM Power bypasses this with its own transcript extraction engine that works with 1000+ languages and has a near-100% success rate. If a video has any captions (auto or manual, any language), we'll get the transcript.

Yes — the All Tabs feature shows every open tab in your browser. Check the ones you want, click Add. You can even close the tabs automatically after they're added. Perfect for research sessions where you've opened 30+ articles.

NotebookLM has no built-in export. NotebookLM Power adds full notebook export — select one or multiple notebooks, click Export, and download JSON files with complete source content (not just AI summaries). Each notebook exports as a separate file, or merge them into one. This is the only way to back up your NotebookLM data.

NotebookLM Power supports 12 export formats: PDF, DOCX, HTML, PNG, Markdown, Plain Text, CSV, Anki flashcards, LaTeX, OPML, Kahoot quizzes, and Aiken format. Export any artifact — study guides, briefing docs, flashcards, mind maps, quizzes — in the format you need.

NotebookLM's native slide export gives you static images, not editable slides. NotebookLM Power exports slides as images in a ZIP, and study guides/briefing docs as editable DOCX and Markdown files that you can import into Google Slides, PowerPoint, or Canva.

NotebookLM doesn't have native folders. NotebookLM Power adds a folder system directly on the NotebookLM page — create folders, drag notebooks into them, add emoji icons. Your notebooks stay organized without any workaround.

NotebookLM doesn't support searching across notebooks. NotebookLM Power's Activity Log tracks everything you've ever added across all notebooks — searchable by title, URL, or notebook name. You can always find where you saved something.

NotebookLM has a ~13% hallucination rate (much lower than ChatGPT's 40%), but it's not zero. Citations can sometimes point to wrong sections. NotebookLM Power doesn't change how NLM's AI works — but our Merge feature helps by giving NLM cleaner, better-structured input. When you merge 20 YouTube transcripts with proper timestamps, NLM can cite specific moments more accurately than when processing raw URLs.

NotebookLM processes documents in chunks and has a 500,000-word limit per source. Large PDFs may be partially processed. NotebookLM Power's Export feature extracts the full content that NLM actually indexed — so you can verify what NLM "sees" and what it missed. For very large documents, consider splitting them into parts before uploading.

Merge combines multiple selected sources (YouTube videos, web pages) into one text document. Each source's content is extracted (YouTube transcripts with timestamps, web page text), cleaned, and combined into a single text source. This saves notebook space — 50 videos become 1 source slot — and gives NLM a unified document to analyze, improving citation quality.

Yes — NotebookLM Power's Translate feature (Pro) converts source content to any of 13 languages before adding it to your notebook. Powered by Google Gemini AI. Perfect for researchers working with sources in foreign languages. Timestamps and formatting are preserved during translation.

With parallel transcript fetching, merging 100 YouTube videos takes approximately 2 minutes (previously 10+ minutes). You can see real-time progress for each source, and the process survives if you accidentally close the extension popup.

Yes, the core features are free: add the current page to any notebook, Notebook Folders, Activity Log, context menu (right-click Add), and inline YouTube buttons. From the Feed and All Tabs, free users can add 5 sources per session. Merge, Translate, Export, Smart Sort, and unlimited batch adds require Pro ($5/month).

They solve different problems. NotebookLM Plus ($20/mo, bundled with Google One AI Premium) increases source limits and AI query limits within NotebookLM itself. NotebookLM Power ($5/mo) adds features that NLM doesn't have at any price — batch import from 25+ sites, merge sources, translate, export notebooks, YouTube transcripts. Many users have both.

Instead of adding 50 individual YouTube videos (filling your entire free-tier notebook), Merge combines them into 1-3 text sources. A notebook with 50 merged sources effectively contains 500+ original sources. This is the most practical workaround for the source limit without upgrading to NotebookLM Plus.

The Obsidian destination is currently paused (coming back soon). In the meantime, you can export notebooks as JSON and convert them to Markdown files compatible with Obsidian. The export includes full source content, not just summaries.

The Notion integration is paused for v2 launch (coming back soon). Currently, you can export notebook content and manually import into Notion. Direct sync is planned for a future release.

Auto-Import (RSS feeds + YouTube channel/playlist monitoring) is coming soon. This will automatically add new content to your notebooks on a schedule. Available in a future update.

NotebookLM Power is a Chrome desktop extension and works on any Chromium browser (Chrome, Edge, Brave, Arc, Opera). Mobile is not supported. NotebookLM's own mobile app has significant limitations — no mind maps, no study guides, no slides, limited file types. For serious research, desktop is the way to go.

NotebookLM Power processes data client-side wherever possible. Your notebook content never passes through our servers except for: (1) YouTube transcript extraction via our proxy, (2) AI translation via Gemini API, (3) export processing. We don't store notebook content. Pro license verification uses your email hash only.

No. The extension activates only when you click its icon or visit a supported site. Background processing (playlist sync, RSS) is paused in v2. The extension uses ~2MB of memory when active, zero when idle.

Feed works by extracting links from the page DOM. Some sites use heavy JavaScript rendering that may not be parsed. If Feed is empty, try: (1) scroll down to load more content, (2) wait a few seconds for the page to fully render, (3) use the Current tab to add the page directly by URL.
