Google has introduced a planning stage for Gemini Notebook slide decks and video overviews, allowing users to review the proposed structure before the final output is generated. The update gives users an earlier opportunity to correct the direction of a presentation built from their sources.
Access needs a qualification. Google’s October 19 announcement describes a global rollout to all users over the following week, while its slide-deck help page limits co-creation to Google AI Ultra subscribers. As of October 21, those statements do not establish a consistent eligibility rule. Readers should check whether the review control appears in their account rather than assume an upgrade is required or access is universal.
Review the plan before rendering
Where the feature is available, open a notebook you can edit. In Studio, select Slide Deck and choose the format, output language, length and sources. Enable Review outline notes and select Generate now.
When the outline is ready, choose Review and submit your feedback together. Select Proceed when the plan is ready for rendering. Google’s instructions say the outline cannot be further refined after that step. Generate later follows a scheduled route without an outline, so it is not equivalent to review-first generation.
Users can also begin with a request in chat. Google says the workflow supports choices about content, visual style and format, while the existing quick-generation route remains available. Video overviews receive a corresponding producer-notes review option.
What still needs checking
The slide-deck help page restricts creation to users over 18 and requires notebook edit access. Mobile capabilities may differ, making desktop web the clearer starting point for these instructions.
Selecting an output language does not verify Hebrew typography or right-to-left layout. Check those in the generated file alongside figures, names and source support. Google warns that generated decks can contain factual and visual errors.
Reviewing a plan can help expose a missing section or an unsuitable order before rendering. It does not verify the finished slides. The practical gain is earlier editorial control, with final checking still necessary.
