NotebookLM: A New AI Tool You Should Know About

Regarding the inability to popularize or productize massive achievements, Google stands alone at present. Somewhat like IBM of the yore, its annals must be full of tales where its teams worked on transformative (pun intended) innovations only to allow competitors to adopt its set-aside ideas and outshine.

In NotebookLM. Google may have done the same again. They've developed a potentially game-changing tool and then whispered its existence. It is a tool so quietly tucked away in beta that you'd be forgiven for mistaking it for a forgotten Google+ project. Whether this product benefits Google or not does not matter; it might just be the key to unlocking the true potential of AI for the masses and each of us individually.

While Google's Gemini (formerly Bard) and its army of lesser-known AI experiments battle for the spotlight, NotebookLM was another project toiling away for a while. Just like blogs like ours never mention Google’s other initiatives like AI Studio, Vertex AI, Imagen, etc, almost ever, the same would have remained true about NotebookLM, except that the newest features need more mention than almost anything announced in LLM space, including some of OpenAI’s biggest announcements, in a while.

In summary, it is personalized AI that works with your data in the easiest possible way.

Imagine an AI assistant that's not just smart but smart about your world. You can upload your documents—research papers, business reports, or those cryptic notes you took during a meeting—and NotebookLM will digest them all. When you ask a question, it doesn't spout generic info scraped from the internet; it provides answers rooted in your data. And, creating your data pool is only through copy-pastes and uploads, without the need for other skills.

This magic is powered by something called Retrieval Augmented Generation (RAG). Don't let the jargon scare you—it's just a fancy way of saying the AI combines its knowledge with information from your documents to give you better answers. So, instead of getting vague or irrelevant responses, you get insights that matter to you.

This is far more than working with current Chatbots with uploaded documents. NotebookLM prioritizes information from your uploaded files when generating responses. It acts like an expert who has thoroughly studied your specific documents, ensuring answers are grounded in your context and relevant to your data. Plus, its capacity to ingest is significantly higher.

In practical terms, this example may suffice. One can create a Notebook for a topic, say, Google. One can upload past financial statements, relevant articles, research reports, meeting notes, and even audio/video files to analyze the company’s financial performances in detail.

So far, implementing methods like RAG required building out data lakes, vectorization, and other front-end methods that were both cost-consuming and time-consuming. NotebookLM has made this accessible to all for general-purpose use cases. It comes with the added security and privacy you'd expect from Google (who, let's face it, already knows everything about you anyway).

Of course, there is the usual kicker: in its infinite wisdom, Google seems poised to let this innovation languish in obscurity. It has too many teams (all with fancy names like Gemini, AI Studio, Vertex AI, DataGemma, etc) pushing their own products with slightly different positionings. This internal competition might be why innovations like NotebookLM don't get the spotlight they deserve, occasionally bumping into each other. It's reminiscent of when Google invented the transformer model—the backbone of modern AI—and then let others, like OpenAI, run away with the glory.

Regardless, NotebookLM will be noticed by others (after all, we love in the world of “instant copiability” – one of GenInnov’s oft-discussed themes) and improve quickly. Google itself is working on RIG, an attempt to include vast public data to inject factual accuracy into models. NotebookLM cannot integrate spreadsheets so far, but that, too, must be coming soon.

In the meantime, here's why NotebookLM is worth your attention:
