NotebookLM Expands Globally, Adds Slides and Enhanced Fact-Checking

Last summer, we unveiled NotebookLM, an AI-powered tool designed to assist with research and writing. We're thrilled to announce that we're rolling out an enhanced version of NotebookLM, now powered by Gemini 1.5 Pro, to more than 200 countries and territories worldwide.

From the outset, our vision for NotebookLM was to develop a platform that would help users delve into complex materials, forge new connections from existing data, and streamline the process of drafting. By uploading your sources—be it research notes, interview transcripts, or corporate documents—NotebookLM instantly becomes an expert in the content that's most relevant to you. Our latest upgrade introduces a host of new features:

  • NotebookLM now accepts Google Slides and web URLs as sources, in addition to Google Docs, PDFs, and text files.
  • With inline citations, you can now jump directly to relevant passages in your sources to verify AI responses or explore the original text further.
  • The new Notebook guide feature transforms your sources into practical formats like FAQs, Briefing Docs, or Study Guides, providing a comprehensive overview.

Thanks to Gemini 1.5 Pro's inherent multimodal capabilities, you can now pose questions about images, charts, and diagrams within your sources. NotebookLM will also reference images in citations when they're relevant to the response.

With Gemini 1.5 Pro's native multimodal capabilities, NotebookLM can now understand and cite your questions about images, charts and diagrams in your sources. The diverse ways in which people have adopted NotebookLM have been truly inspiring. Developed in collaboration with authors, students, and educators, it's no surprise that early adopters have woven it into their research and writing processes. For instance, best-selling author Walter Isaacson has utilized NotebookLM to analyze Marie Curie's journals for his upcoming book. Similarly, documentary and podcast researchers have found it invaluable for navigating complex archives to craft scripts or generate story ideas. The synergy between Gemini 1.5 Pro's advanced reasoning and NotebookLM's source-grounding architecture has opened up numerous other applications:
  • In local governance, Thomas Gaume, a resident of Palm Bay, has leveraged NotebookLM to compile a hyperlocal newsletter, drawing on city ordinances, land use data, zoning codes, and council meeting minutes. It's turned him into a "one-person newsroom and publisher."
  • The tool's ability to summarize and adapt interview transcripts has been a game-changer for users like consultant Victor Adefuye, who uses it to spot patterns and themes in sales call transcripts, significantly cutting down on manual analysis time.
  • Nonprofits are using NotebookLM to pinpoint needs in underserved communities and organize data for grant proposals.

We've also seen some delightful and unexpected uses emerge from our 14,000-strong Discord community. Novelists and fan-fiction writers are using NotebookLM to manage intricate storylines, while role-playing game enthusiasts are tapping into detailed descriptions of fantasy worlds for games like Dungeons and Dragons.

Getting started with NotebookLM is a breeze: Upon your first visit, you'll create a notebook and upload documents for a specific project or deliverable. From there, you can read, jot down notes, ask questions, organize your thoughts, or have NotebookLM generate automatic overviews of your sources—like a study guide or a table of contents. Importantly, the sources you upload are not used to train the model.

Whether it's crafting imaginary worlds, penning bestselling biographies, or helping salespeople uncover new leads, NotebookLM has provided U.S. users with robust tools for connecting the dots and gleaning insights from vast document collections. We're eager to see the innovative ways the global community will harness its potential.

NotebookLMのグローバル展開とGemini 1.5 Proへのアップデート、すごいね!スライド機能とファクトチェック強化は、研究や資料作成がもっと楽になりそう。AIツールの進化の速さにいつも驚かされるけど、これでまた仕事の効率が上がりそうで楽しみだわ。😊

これでプレゼン資料も一気に作れるんだね。ただ、自動的なFact-Checkingについては、やはり何を基準にしてるのか気になる。Googleのモデルだから倫理的なバイアスが含まれてないか心配…。でも、研究効率は確実に上がりそう。😅

This global rollout of NotebookLM is cool! 😎 The AI upgrade with Gemini 1.5 Pro sounds powerful, but I wonder how it handles tricky fact-checking in different languages.
