Until now, Gemini in Google Slides worked one slide at a time. Since October 29 it can take a single request in the side panel and apply it across a whole presentation: Gemini decides which slides need changing and edits them directly, leaving normal, editable slides rather than a picture of a deck.

What it can do

Restyle the deck. Fonts, backgrounds and color schemes can be changed everywhere at once, including on request to match the style of another file.
Update content. Simplify, expand or refocus the presentation, using files from Google Drive as the source.
Merge or add slides. For example, turn slides 5 to 7 into a single summary slide.
Fix consistency. Align title styles or remove page numbers across every slide.

When Gemini finishes, the side panel shows a summary of what changed. The edits count as your own, so undo and version history work as usual.

Who gets it

The feature works in English only. It is included in Business Standard and Plus, Enterprise Standard and Plus, Google AI Pro for Education, and the consumer Google AI Pro and Ultra plans. The rollout started on October 29 and Google says it may take more than 15 days to reach everyone. Until at least December 1, Workspace customers get higher promotional limits for multi-slide work; after that, per-user limits apply, and Google says it will publish them in the Help Center first.

Files in the Gemini chat, too

On the same day, October 29, Google added file editing to the Gemini app itself. Gemini can now create a file in the chat, open it full screen for you to edit by hand, and revise parts you highlight. It works with PDFs, Google Docs and Sheets, slide decks, Markdown, plain text and code. The feature is available to all users in every language the app supports; on mobile only PDFs can be previewed and edited, while the other formats need the web version.

What this means if you make presentations

If your decks already live in Google Slides and you pay for Workspace or Google AI Pro, try this before buying a separate tool: restyling and tidying an existing deck is exactly what it is built for.

If you start from a blank page or need designed layouts quickly, dedicated generators such as Gamma still go further. See our comparison Gamma vs Pitch and the full list of AI tools for presentations.

If you work in another language, wait: deck-wide editing is English-only for now.
