Gemini in Google Slides: How to Edit a Whole Deck, Create Slides and Images

Gemini in Google Slides can now edit a whole presentation from one request.

You can ask it to restyle every slide, rewrite the deck for a new audience or merge slides together, and it makes the changes as real, editable edits.

This guide covers everything: who can use it, how to open the side panel, how to generate a full deck, images and single slides, how to rewrite a whole deck and apply a new look, and the limits you should know about.

What is new: whole-deck editing

Until now, Gemini in Slides mostly worked one slide at a time. You could create a slide, write a title or make an image, but changing the look or content across 20 slides still meant 20 separate jobs.

On October 30, 2026, Google’s Workspace Updates blog announced that Gemini in Google Slides can now edit multiple slides, or an entire presentation, from a single prompt in the side panel. The rollout started on October 29, 2026.

Gemini works out which slides need changes and applies the edits directly. Google says the edits “are applied as if you made them,” which means they are normal Slides edits, not flat images pasted on top.

Google lists four main things you can do:

• Refresh visual styles: change fonts, backgrounds and color schemes across the deck, or match the style of another presentation.
• Update content: simplify, expand or change the focus of the deck, grounded in your Google Drive files.
• Combine or expand slides: condense several slides into one, or add new slides.
• Consistent styling: line up title styles or remove page numbers on every slide.

Note: When Gemini finishes, it shows a summary of what it changed in the side panel. If you do not like a change, use undo or version history to go back.

This builds on the June 2026 update, when Gemini in Slides learned to create a complete, editable multi-slide presentation from one prompt, grounded in your Drive files and able to copy the style of a reference deck.

Who can use Gemini in Slides

Whole-deck editing and full-deck generation need a paid plan. Here is the list from Google’s announcement.

A few more details matter:

• Rollout speed: Google calls it an “extended rollout,” which can take more than 15 days for the feature to show up. If you do not see it yet, it may simply not have reached your account.
• No admin switch: Google says there is no separate admin control for this feature. If your organization has Gemini in Workspace turned on, it comes with it.
• Free accounts: a free Google account does not get these Slides features. You can still make a deck in the Gemini app and export it to Slides, which I cover in my Gemini file creation guide.

How to open the Gemini side panel

Almost everything happens in the Gemini side panel on the right of the Slides window.

1. On your computer, open a presentation in Google Slides at slides.google.com.
2. At the top right, click Ask Gemini (the Gemini star icon).
3. The side panel opens. If the deck already has text, Gemini may show a short summary of it.
4. Pick one of the suggested prompts, or type your own request in the prompt box at the bottom and press Enter.
5. To reference a file from Drive, type @ followed by the file name inside your prompt.

Two other entry points are useful. In the toolbar, or from the Insert or Slide menu, you can choose Help me create a slide. And under Insert > Help me visualize, you can make an image, a slide or an infographic.

How to generate a full presentation

If you are starting from nothing, Gemini can plan and build a full deck. Google’s help page gives these steps:

1. Open Google Slides. On the start screen, click Presentation, or open a blank presentation and click Ask Gemini at the top right.
2. In the side panel, describe your topic and goal. Google’s example: “Create a 5-slide presentation on quantum computing for a general audience with a modern design.”
3. Optional: click Add sources, then Add from Drive, pick a file and click Add. You can also let Gemini search the web, Drive, Chat or Gmail.
4. Optional: click Match presentation style, then Add from Drive, and pick a deck whose look you want to copy.
5. Answer Gemini’s follow-up questions about tone, audience or content, or skip them.
6. Click Next. Gemini shows a plan with an overview, the sources and one step per slide.
7. Edit the plan if needed: click a slide outline to change its title or description, use Add step to add a slide, Delete to remove one, or Update plan to let Gemini redo it.
8. Click Approve.
9. Keep the Slides tab and the side panel open while Gemini builds the deck. It can take a few minutes. You can switch to other tabs, but do not close Slides.

The result is a normal, editable presentation. Every text box, shape and image can be changed by hand afterwards.

How to rewrite or restyle a whole deck

This is the new part. Use it on a deck you already have, whether Gemini made it or you did.

1. Open the presentation and click Ask Gemini to open the side panel.
2. Type one request that describes the change for the whole deck. Be clear about the scope, for example “on all slides” or “slides 5 to 7”.
3. If the change depends on another file, add it with @ and the file name, such as a new report or a brand template.
4. Send the prompt. Gemini decides which slides need changes and edits them.
5. Read the summary of changes in the side panel.
6. Click through the deck to check every edited slide, especially numbers and names.
7. If something is wrong, press undo (Ctrl+Z or Cmd+Z) or open File > Version history and restore an earlier version.
8. Ask for follow-up fixes in the same panel, such as “Keep slide 3 as it was before.”

Good whole-deck jobs include shortening every slide to three bullets, rewriting a technical deck for executives, updating figures from a new spreadsheet, merging repeated slides, and making all titles match.

A tip before big changes: make a copy first with File > Make a copy. Version history works, but a copy makes it easy to compare before and after side by side.

Applying themes and matching a style

There are two ways to change the look of a deck.

1. Ask Gemini to restyle it. With whole-deck editing, you can ask for fonts, backgrounds and color schemes to change across all slides.

Google’s own example prompt is “Update this whole deck to match the style of this [reference file].” This is the fastest way to bring an old deck in line with your company template.

2. Use the Slides theme tools. The classic theme panel still works and is often the cleanest option for a full theme swap:

1. Click Slide > Change theme (or the Theme button in the toolbar).
2. Pick a theme from the list, or click Import theme to use one from another presentation.
3. Then ask Gemini to fix anything the theme did not cover, such as “Make all titles the same size and color” or “Remove page numbers from all slides.”

New slides that Gemini creates use your current theme, so set the theme first and then generate slides for the best match.

Create single slides and write text

Generate one new slide

1. Open the side panel and describe the slide. Use @ to point to a Drive file if needed.
2. Gemini shows a draft slide. Click Retry for another version, Insert to add it, or type a new prompt to refine it.

You can also use Insert > Help me visualize > Slide (beta) or Infographic (beta), then click Insert as new slide or Insert on this slide.

Write a title or body text

1. Click an empty text box on a slide that already has some content.
2. Click Write a title for a title box or Help me write for body text.
3. Review the text and click Insert.

Other side panel jobs

The panel can also summarize the deck, answer questions about it, search the web when you say “Use Google Search,” use your Gems, and even create a Doc, a Sheet or a draft email from the slides.

Generate and edit images

Google’s help page says image generation in Slides and Vids uses the Gemini 3 Pro image model.

1. Click the spot on the slide where you want the image.
2. Go to Insert > Help me visualize > Image. (In the side panel you can also click Tools > Create images.)
3. Type a clear prompt. Include the subject, setting, distance, materials and background. Avoid figurative language.
4. Optional: click Add a style, or set Aspect Ratio to Square (1:1), Wide (16:9) or Tall (9:16).
5. Click Create, then click a result to preview it on the slide.
6. Click Insert to place it.

To edit an existing image, click it, choose Edit image, describe the change and click Create. Then pick Replace with image, Insert as image or Insert as background. There is also a one-click Remove background option. Google notes that generated images are for use inside Google Slides and Google Vids.

Prompts that work

These follow Google’s own examples, plus common real-world jobs. Change the parts in brackets.

Update this whole deck to match the style of @[Brand template 2026].

Update this presentation to include more details based on @[Q3 results report].

Summarize slides 5-7 into a single slide.

Make the titles on all slides the same font size and color.

Rewrite every slide for a non-technical executive audience.
Max 3 bullets per slide, max 12 words per bullet.

Change the background on all slides to a light grey and use a dark
blue for every title. Remove page numbers from all slides.

Add one new slide after slide 4 that compares Option A and Option B
in a two-column table.

Create a 10-slide sales kickoff deck from @[FY27 plan] for the sales
team. Include an agenda, 3 goals, a timeline and a Q&A slide.

For images, be literal: “A flat illustration of a small team around a laptop, soft blue background, wide 16:9” works better than “teamwork vibes”.

Limits and privacy notes

• English only for whole-deck editing and full-deck generation at launch. Image generation supports many more languages.
• Desktop only for deck generation, according to Google’s help page. The Slides mobile apps do not have these tools.
• Usage limits: Workspace customers get promotional, higher limits for multi-slide creation through at least December 1, 2026. After that, per-user limits apply, and Google says it will publish them in the Help Center first. Google has not shared exact numbers yet.
• Gemini picks the slides: with whole-deck edits, Gemini chooses which slides to change. Always review the summary and the slides.
• Chat history is temporary: the side panel conversation is lost if you refresh, close the deck or go offline. Insert good suggestions right away.
• Activity: Google says side panel conversations in Slides are not saved to Gemini Apps Activity.
• Accuracy: AI can get facts and numbers wrong. Check everything before you present.

Gemini in Slides vs Copilot in PowerPoint

If your team uses Microsoft 365, Copilot in PowerPoint is the direct alternative. Both can build a deck from a prompt or a file, rewrite slides and create images.

The main differences come down to where your files live and which plan you already pay for. Gemini grounds decks in Google Drive, Gmail and Chat, while Copilot grounds them in OneDrive, SharePoint and Outlook.

For a full walk-through of the Microsoft side, see my Copilot in Word, Excel and PowerPoint guide.

If you also live in Gmail, the same Gemini features show up there too. See Gemini in Gmail.

Troubleshooting: Common Problems and Fixes

I do not see the Ask Gemini button

Check that you are signed in with an eligible plan (AI Pro, AI Ultra, Business Standard or Plus, Enterprise Standard or Plus, or AI Pro for Education). On a work account, your admin must have Gemini for Workspace turned on. Use a desktop browser, not the mobile app.

Gemini only edits one slide when I asked for all of them

The whole-deck feature is on an extended rollout that can take more than 15 days. If you have it, make the scope clear in your prompt: “on every slide” or “slides 2 to 9”.

The feature does not understand my prompt

Whole-deck editing and deck generation are English only right now. Set your Google account language to English and write your prompt in English.

Gemini changed a slide I wanted to keep

Press undo, or open File > Version history and restore the earlier version. Next time, add “do not change slide X” to the prompt.

Deck generation stopped halfway

You probably closed the tab or the side panel while Gemini was building. Keep both open until it finishes, then try again.

I hit a limit message

Promotional limits run through at least December 1, 2026 for Workspace. After that, per-user limits apply. Wait and retry later, or check Google’s usage limits page in the Help Center.
