Google LLC today updated its NotebookLM service with a set of online research and coding features designed to save time for users.

NotebookLM is part note-taking app, part data analysis tool. Workers can upload a collection of business documents and have the application summarize their contents. Students can use it to collect information for homework projects. NotebookLM also lends itself to certain related tasks such as creating presentations.

Today’s update upgrades the artificial intelligence engine that powers the service to Gemini 3.5, Google’s newest family of large language models. The company debuted the first algorithm in the series last month. Gemini 3.5 Flash is positioned as an entry-level model, yet outperforms Claude Opus 4.7 across several benchmarks. Google says that it can generate output four times faster than competing LLMs.

The search giant compared the new version of NotebookLM to the previous release using a set of sample tasks. According to Google, the new version performed better across 78.2% of the online research and source discovery tasks used in the evaluation. It’s also significantly better at analyzing lengthy documents.

The second major change to NotebookLM is a set of new features powered by Google’s Antigravity code editor. The latter tool, which debuted last November, can split a software project into smaller tasks and assign each one to a separate AI agent. Running multiple agents in parallel is faster than completing tasks one after one another.

Each NotebookLM workspace now comes with a virtual machine that the tool can use to write and run code. A data scientist, for example, could request a script that organizes spreadsheets from different sources into a single consistent format. Google says that a collection of more than 100 pre-packaged “software skills” will help users optimize NotebookLM’s output quality.

The Alphabet Inc. unit also released several other enhancements as part of today’s update.

NotebookLM is now better at helping users find data sources relevant to their research projects. Additionally, the service can generate more than a half dozen file types that weren’t supported before including Word, PowerPoint, Excel and PDF documents. Another newly added file format, JSON, will make it easier to load NotebookLM’s output into external applications.

The new capabilities are accessible to consumers with a Google AI Ultra subscription as well as organizations that use Google Workspace’s AI Ultra Access and AI Expanded Access add-ons. The search giant plans to broaden the features’ availability over time. Another future update will expand the range of file formats that NotebookLM supports.
