NotebookLM is getting a major update from Google. The tool now has a new Deep Research feature and support for many more file types like Google Sheets, Word files, Drive links, PDFs from Drive, and soon images.
These changes are made for people who handle long research work and want everything in one place without moving between different apps.
Google wants NotebookLM to act less like a simple note tool and more like a helper that can study topics, sort information, and give ready-to-use points. Many users depend on mixed files—notes, tables, drafts, screenshots—so Google is trying to bring all of that into a single flow.
Deep Research is the biggest part of this update. It works like a quiet helper that studies your topic and collects clear information from the web.
You only need to type your topic or question.
After that, Deep Research:
It does this while you continue your work. You can save the report in your notebook and add more files anytime.
Many people waste hours switching tabs, copying lines, and collecting small notes. Deep Research cuts that time.
It doesn’t replace your thinking, but it helps you start with a basic structure so you can focus on writing, checking facts, or planning your project.
NotebookLM will now accept more kinds of files, which is helpful for people who store their work across multiple formats.
Google has added support for:
This means you can bring almost everything—your notes, your tables, your drafts, and even snapshots of written pages—under one tool.
Most people use different apps for different tasks. Your plan may be in Word, your numbers in Sheets, your extra notes in PDF, and your handwritten notes in images. Having all of this in NotebookLM makes your study or report work smoother.
For example, a student preparing a project can upload a Word file, a Sheet with marks or data, and a photo of a rough page. Then, Deep Research can search the web and help fill in the missing points. This keeps the full project in one place.
The update is not only about files.
It also helps people stay organised.
Report writers, students, journalists, analysts, and teachers all deal with mixed content.
NotebookLM now supports that flow instead of breaking it.
Imagine you are preparing a market study. You upload a Word draft, a Sheet with numbers, a PDF from a past report, and a phone photo of notes. You then ask Deep Research to gather new points from the web.
In a short time, you get a clear list of points with links. You do not have to open ten different tabs for every detail.
Google says the update is rolling out now. Image uploads will reach all users in the coming weeks.
Other file types are already available or in the process of appearing for most accounts.
NotebookLM is slowly becoming a better place for long projects. With Deep Research collecting information and new file support bringing everything together, users can spend more time understanding their topic rather than managing their files.
Google’s new update makes NotebookLM more practical for everyday research. Deep Research helps with collecting clear points from the web, and the wider file support lets users keep all their material in one tool.
For anyone who handles large topics, reports, or study work, this update can make things much easier.
