Google adds outline review before Gemini Notebook generates slides and videos

Google is giving Gemini Notebook users a chance to change the plan before it generates a slide deck or video overview. Announced on October 19, 2026, the new co-creation controls let users steer content and inspect planning notes, rather than moving directly from an initial request to a finished output.

The flow begins in chat: ask Notebook to create slides or a video overview, and it suggests topics drawn from the sources in the notebook. After confirming those topics, users can give further direction on content, visual style and format. That puts a topic-selection step between the opening request and the more detailed creative instructions.

Check the plan before rendering

For a closer look at what Notebook intends to produce, users can switch on the new Review toggle. This opens a review stage in the studio panel before the output is rendered. The material users inspect differs by output: a slide deck has outline notes, while a video overview has producer notes.

• For slides, select “Review outline notes” to inspect the planned deck before generation.
• For video, select “Review producer notes” to inspect the plan before the video renders.

The review stage also accepts additional feedback. Google gives two examples: asking for an executive summary at the beginning, or changing the order of a scene. These are directions about how the material should be organized, supplied before generation. Once the plan looks right, selecting “Proceed” produces the final deck or video.

A shortcut for a clear brief

Users who already know what they want do not have to start with Notebook’s topic suggestions. Google says they can specify the desired output in their prompt, and Notebook will go straight to the review flow. That route lets a detailed opening request lead directly into checking the plan, instead of working through the initial topic-selection exchange.

Google says the co-creation capabilities are rolling out globally to all Gemini Notebook users over the week following the October 19 announcement. Access is therefore arriving through a phased rollout, rather than being described as immediately available to every user.
