The slide you miss is the one the client spots. On October 30, 2026, Google announced that [Gemini](https://learn.ynteractive.com/content/tool/gemini) in Google Slides can edit several slides or a whole presentation from one [prompt](https://learn.ynteractive.com/content/glossary/prompt). In this short practice you make that edit for a made-up benefits firm, check it, and fix what it leaves behind. Be clear on what we tested: on October 31 the whole-deck edit had not reached our account, so those two steps follow Google's description. The panel, slide text, Slide preview, Replace, Undo and Version history are from the real app. That's the basic shape: name the old value and the new one, say what must stay, read the summary, then open each slide it touched and read around the change. Google says these edits can be undone or reverted with version history. It is English only at launch, for Business Standard and Plus, Enterprise Standard and Plus, Google AI Pro and Ultra, and Google AI Pro for Education, and Google warns the rollout may take longer than 15 days. Until it reaches you, the one-slide route with Replace works the same way, a slide at a time. - Tools: Google Slides - Time: about 4 minutes, 8 steps in 3 chapters - Level: beginner, no coding needed - Price: free ## Practice first, then build it for real Practice based on Google's published description; Google published no screenshots of the whole-deck edit. It requires Business or Enterprise Standard or Plus, Google AI Pro or Ultra, or AI Pro for Education, and is still rolling out. This is a practice copy: no account is needed and nothing touches your Google Drive. The firm and client are made up. To build it for real you need your own Google Slides account, and some services charge once you use them for real work, so check each tool's current pricing. ## Try it yourself, free Reading the steps is a start. Doing them is how it sticks. The interactive module walks you through every click in a practice copy of Google Slides, checks each step, and never touches your real accounts.

In the module you watch each one, then do it yourself in a practice copy that checks your work. ### 1. One prompt for the whole deck 1. **Open Ask Gemini.** This is Dana Reyes at Harbor Point Benefits. Her client review is tomorrow, and two facts just changed. Open the deck in Google Slides and click **Ask Gemini**, the star at the top right. This is Dana Reyes at Harbor Point Benefits. Her client review is tomorrow, and two facts just changed. 2. **Say what changed, once.** Name the old value and the new value, then say what must not change. Google says Gemini works out which slides need the edit and makes them itself. Paste the prompt and press **Enter**. Don't name slide numbers: finding them is Gemini's job. Now say what changed, once. Give the old value and the new value, then say what must not change. Google says Gemini works out which slides need the edit, and makes the changes itself. ```text Two facts changed. The renewal date moved from March 1 to April 1, and the premium increase is now 4 percent, not 6 percent. Update every slide that mentions either one and leave everything else as it is. ``` 3. **Read the summary of changes.** Google says a summary of the changes appears in the side panel. Click it. We haven't seen the real one, because this edit hadn't reached our account, so this screen is a plain stand-in and Google's wording may differ. Google says a summary of the changes appears in the side panel. We haven't seen the real one yet, so this screen is a plain stand-in. ### 2. Check it like you will present it 4. **Open the premium slide.** A summary is a claim, not proof. Click the **premium** slide in the filmstrip and read the number yourself. A summary is a claim, not proof. 5. **Open the renewal slide.** Plus 4 percent, as asked. We closed the panel here to give the slide more room. Now click the **renewal** slide, and read past the big date. Plus four percent, as asked. 6. **Fix the line a date change leaves behind.** The date is right, but the line under it still says the work must begin **immediately**. When we changed this date in the real app, Gemini left that line alone, as we asked. Only Dana knows the new plan. The slides stay normal slides you can edit, so type over the word. Here, type **by February 1**. The date is right, but the line under it still says the work must begin immediately. When we changed this date in the real app, Gemini left that line alone, as we asked. Only Dana knows the new plan. These stay normal slides, so type over it. By February first. ### 3. Your way back, and your way today 7. **Know your way back.** Google says these edits behave as if you made them by hand, so Undo or version history can reverse them. Click the **clock icon** at the top to see Version history. For a deck someone else built, look here before you trust a big edit. Google says these edits behave as if you made them by hand, so undo or version history can reverse them. 8. **If it says no today: one slide at a time.** Google warns this rollout may take longer than 15 days. On October 31 our account answered that it can "only edit the currently active slide". If you see that, open one slide, ask for the change on that slide, and a **Slide preview** opens. Check it, then click **Replace**. That is the route we ran for real. Google warns this rollout may take longer than fifteen days. If Gemini tells you it can only edit the current slide, that's your route today.
