Google expands Gemini Notebook with a more controllable process for creating slide decks and video overviews

Google is updating Gemini Notebook to give users more creative control when generating Slide Decks and Video Overviews, two types of content artifacts designed to turn source material into presentation-ready drafts. In a product post published October 19, the company said the update changes how the tools move from a first prompt to a final deliverable, shifting from a single jump to an iterative creation flow based on the user’s sources.

The post says Gemini Notebook will now “walk you through the creation flow” for Slide Decks and Video Overviews using a quick process. Instead of going immediately from an initial prompt to a finished output, the assistant will suggest topics to include in the artifact first, and then ask the user to confirm before the tool proceeds further.

After a user confirms the suggested plan, the system can be steered to refine the content and also adjust the visual style and format. Google positions the change as responding to user feedback and expanding creative control “from start to finish” across the two specific output types.

For users who want even more involvement, Google introduced what it calls a “Review toggle.” When enabled, users can review plan notes in the notebook’s studio panel before the final content is rendered. For slide decks, the company describes a “Review outline notes” step, and for video overviews, a “Review producer notes” step.

Google said the review stage is not only a read-through of what will be generated. It also supports additional feedback that can influence the artifact, including requests like adding an executive summary at the beginning of a slide deck, or swapping the order of scenes in a video overview. Only after the user believes the output looks right does the workflow move to final generation via a “Proceed” action.

The company also described alternative interaction paths. If someone already knows what they want to create, they can specify requirements in the prompt and Gemini Notebook will go straight to the review flow. For those seeking speed over iteration, Google says users can still skip the review toggle and generate artifacts as usual through the studio panel.

Google did not provide additional details in the announcement about how the suggested topics are selected beyond stating that the creation flow is “based directly on your sources.” It also did not specify what sources are supported, how user edits are reflected internally, or whether the update changes output quality measures such as summary length, slide count, or video structure.

The update highlights how Google is pushing “co-creation” workflows for generative AI products, emphasizing user confirmation, checkpoints, and editable plans rather than fully automated generation. Slide decks and video overviews are common formats for internal communication, training, and marketing, which makes controllability a practical differentiator for teams that need consistent structure, branding, and message alignment.

Google said the capabilities are rolling out globally to all Gemini Notebook users over the upcoming week. That timing suggests the feature is being deployed in waves rather than being limited to a select group, though the announcement did not name any exceptions or phased availability by region, account type, or subscription tier.

For users and businesses, the main question is how the new review step changes the daily workflow: whether the ability to reorder scenes or insert an executive summary reduces rework, and whether the suggested topic plan improves consistency when working from lengthy or complex source material. Google’s post stops short of quantifying time saved or user adoption, but the product direction is clear: more gating, more steering, and a clearer path from source material to final slides or a video overview.
