For those of you who interact with AI chatbots daily, we’re sure you use them as a tool to aid you in studying and researching.
ChatGPT, Gemini, Claude, Perplexity, and other similar AI models are known for providing the information you seek when you present them with questions about whatever topics you’re most focused on. Google offers something a bit more reliable when it comes to doing proper research on subjects both big and small. NotebookLM, which was originally codenamed “Project Tailwind,” is the tech giant’s signature AI-powered research and note-taking assistant. Not only does it search the web for legit sources of information, but it also lifts data from the documents you choose to upload.
To learn more about that NotebookLM process and the rest of its impressive capabilities, be sure to put this how-to guide to good use.
NotebookLM is a powerful AI research tool — here’s why
Powered by Google’s Gemini AI, NotebookLM works as a digital research assistant that can gather and analyze information from the web as well as content you upload from Google Drive.
You can choose Fast Research for quick answers or use Deep Research for a more comprehensive report. Featured notebooks from news organizations, researchers and Google itself showcase how the tool can compile research across topics like biology, arts and culture and parenting.
To start, create a new notebook and enter a question. For example, I asked: “What are the most influential video games of all time?” NotebookLM returned a concise summary backed by 10 cited sources, along with suggested follow-up questions to deepen the research. In addition to pulling information from the web, it can analyze files you upload — including PDFs, documents, images and audio — to surface relevant insights.
What makes NotebookLM especially compelling is how it transforms raw research into formats suited for different audiences. Its Studio feature can turn your notes into an audio overview presented as a podcast-style conversation between two AI hosts, or generate a video overview for quick sharing.
Get instant access to breaking news, the hottest reviews, great deals and helpful tips.
NotebookLM can also convert your research into a slide deck, mind map, detailed report, flashcards, infographic, data table or quiz — making it easy to repurpose information for presentations, studying or team collaboration.
NotebookLM is a great AI tool for several practical uses
In the following cases, NotebookLM excels at what it does:
- Prepping for exams: by generating summaries and creating flash cards, students can better prepare for upcoming tests and easily identity their weakest areas
- Producing a long-form article or white paper: comparing documents & sources, extracting their most crucial information, and pulling the best quotes is incredibly useful for writers looking to craft a more structured long-form piece of writing or white paper document
- Meeting breakdowns: uploading meeting transcripts and PowerPoint presentations can help NotebookLM generate better summaries, find actionable items, and zero in on the decisions & follow-ups that were decided upon
