Project
Google's AI-powered research and note-taking tool, formerly NotebookLM, that summarizes user-provided sources into notes, audio overviews, and infographics.
David Autor's trial of 133 patent lawyers found AI improved everyone's drafts, but only seniors kept a skill gain once it was gone. Firms that expected the tool to train junior associates still have to pay for that training, on the evidence of a Google-run working paper.
Reality
Expert Intelligence lets you ground a notebook in ebooks you own on Google Play, and because the ownership check runs per person rather than per notebook, a shared workspace turns a book purchase into a seat licence.

David Autor and Tanya Rodchenko's trial of 133 patent attorneys found AI lifted drafting quality for everyone but built stronger judgment only in seniors. Juniors' judgment scores split toward both ends with no average gain, so better drafts no longer show a firm which juniors are learning.

Google has finished rolling out Gemini Notebook's mobile Live Chat to 100% of Google AI Pro users, according to its rollout announcement. Teams already on Pro can start a mobile trial over their notebook sources now instead of waiting for their accounts to be reached.

On September 2 the per-feature daily counts that let teams plan capacity become five-hour and weekly compute windows, with free users promised standard limits and paying ones more, neither stated as a figure.

Google is adding real-time voice conversations in nearly 100 languages and a mobile audio recorder to Gemini Notebook, the product formerly called NotebookLM. Training teams get a way to capture spoken content, though it arrives in stages and its retention rules are undocumented.
Reality
Gemini 3.8 Flash TTS and Flash-Lite TTS arrive with matching APIs, more than 2,000 stock voices and a path from a 30-second sample to a replica voice. Securing the speaker's permission is the customer's job.
Reality
Google says rollout of Interactive Learning Overviews began on September 15 and that administrators may need to enable Gemini Notebook, so the review of generated quizzes and flashcards lands on whoever owns the source documents.
Reality
Google's mobile voice mode answers from the files you uploaded. That makes notebook curation the thing that determines answer quality. The rollout starts with Google AI Ultra, and Google has not published a date for everyone else.
Reality
Compute-aware quotas mean the meter reads whatever a task actually costs, and Google has published no figures for it. The compensation is a reset that arrives inside a working day, plus a web-only queue for heavy artifacts.
Reality
Google is letting notebooks read ebooks the user already bought, from a catalog it puts above 100,000 titles. Ownership is checked per person, so one shared notebook grounds differently for each collaborator.
Reality
Google has wired 100,000 eligible ebooks into Gemini Notebook behind a per-reader ownership check. Every other catalog owner now has to decide whether a grounded answer sells the book or replaces it.
Reality
Expert Intelligence turns a Play Books receipt into an import permission. Every publisher outside the launch library is left working out what a per-title AI grant is worth, and the same catalog sits in a class action.
