Build the deck from what you already have

Most slideshows don’t start from nothing. You have a page of notes, last year’s deck, or a pile of facts for the school fundraiser. This week, four tools that build slides inside the program you already use, starting from your material instead of a blank slide. AI can sound sure and still get a name or a number wrong, so read every slide before you share it, and keep private details out of any tool you don’t fully trust.

Claude: claude for PowerPoint: new slides in your own template

An add-in that puts Claude inside PowerPoint. It reads your deck’s template, so new slides use your layouts, fonts, and colors.

1. Install “Claude for Microsoft 365” from Microsoft AppSource (choose Get it now).
2. Open PowerPoint, activate the add-in, and sign in with your Claude account.
3. Open the deck you want to build on, with your template already applied.
4. Ask for what you need, like “Add an agenda slide using the one-column content layout” or “Turn these bullets into a process flow diagram.”

When to reach for it: you already have a deck with a look you like and need more slides that match it. It is for the Pro, Max, Team, and Enterprise plans, and it runs in PowerPoint on the web, Windows, and Mac, not on iPad or Android. Anthropic says to review every change and does not recommend it for final client deliverables without a human check.

ChatGPT: chatGPT for PowerPoint: a first draft from your notes

A sidebar add-in that can draft a deck from source material, add or revise slides in an existing deck, and tailor a deck for a specific audience.

1. In PowerPoint, go to Home, then Add-ins, and search for ChatGPT.
2. Add it, open ChatGPT from the ribbon, and sign in with your ChatGPT account.
3. Save a duplicate of your file first, so you can go back if an edit goes wrong.
4. Paste in your notes and be specific, like “Build a 6-slide update for our school fundraiser from these notes,” or “Add a risks slide after the market overview.”

When to reach for it: you have rough notes and want a draft to react to, or an existing deck needs retelling for a different audience. It is open to every plan, including Free, though Free and Go have limited usage. OpenAI says slides may not match your template, some chart and shape editing is limited, and it can make mistakes when editing or deleting. Under Microsoft’s Marketplace terms, Microsoft can read the content of your PowerPoint files, so think twice before using it on a private deck.

Copilot: copilot in PowerPoint: reuse an old deck’s content or style

Microsoft 365 Copilot in PowerPoint can use a deck you already have as the starting point for a new one, or borrow one deck’s look for another.

1. Open PowerPoint and start Edit with Copilot.
2. Select Reference file and choose a PowerPoint presentation.
3. Ask Copilot to create a new presentation using the content or style of the file you picked.
4. To restyle a deck instead, open it, start Edit with Copilot, reference the deck whose look you want, and ask Copilot to apply its style, theme, or formatting.

When to reach for it: a good deck already exists and you need a new version for a new group, like this year’s take on last year’s reunion slideshow. This is a Microsoft 365 Copilot feature in PowerPoint on Windows, the web, and Mac, not the free Copilot app. The July 1, 2026 release note does not say which licenses include it, so check your own. Microsoft says it respects existing file permissions.

Gemini: gemini in Google Slides: a deck from a plan you approve

Gemini builds an editable presentation from your description, can use files from your Drive as sources, and shows you a plan before it makes a single slide.

1. On a computer, open Google Slides and choose Presentation, or click Ask Gemini in a blank deck.
2. In the side panel, describe the deck. Use Add sources to bring in Drive files, and Match presentation style to copy the look of an existing deck.
3. Answer Gemini’s follow-up questions (or skip them) and click Next.
4. Edit the outline it proposes, click Approve, and keep the tab open while it builds.

When to reach for it: you want to check the outline before any slides exist. It needs an eligible Google Workspace or Google AI plan, and as of this writing it works on desktop only and in English only. Google says suggestions may be inaccurate.

Try this

Pick a page of notes or a deck you already have, and open whichever of these four tools you can reach for free. Ask for just three slides and say who they are for, like “Three slides for parents at our fundraiser kickoff, using these notes.” Then check every name, date, and number against your notes before it goes anywhere. See whether starting from your own material gets you further than a blank slide.
