Google is enhancing its NotebookLM Audio Overview with three new formats: Brief, Critique, and Debate, which are currently hidden behind a feature flag but show signs of an impending public rollout. Brief offers a quick, fixed-length summary; Critique provides AI-generated feedback with adjustable lengths; and Debate features contrasting discussions on topics. These updates aim to improve user experience and support diverse audio needs within the platform.

Google is developing a "projects" feature for its Gemini platform, allowing users to organize work and research in dedicated spaces. This feature will enable file management, project-specific instructions, and enhanced interaction with documents during AI conversations, catering to professionals and students. While the interface is mostly complete, there is no confirmed launch date yet.
