Copilot vs ChatGPT for PowerPoint Add-ins Compared on Cost and Output

Is Copilot better than ChatGPT for PowerPoint?

For a company already on Microsoft 365 with Copilot licenses, Copilot is the more integrated choice. It reads a Word file straight from OneDrive or SharePoint, it uses your organization’s template when you open that template first, and it saves the finished presentation to OneDrive with a link to review it. For everyone else, ChatGPT is the easier one to get: the add-in installs from Home, then Add-ins, works on every ChatGPT plan, and does not need a Microsoft Copilot license at all.

On the quality of the slides themselves, the honest answer is that both produce a usable first draft and neither produces a finished client deck. Microsoft’s own guidance asks you to structure the Word file with Styles so Copilot can break it into slides. OpenAI’s help center lists template adherence as a current limitation and says generated slides “may not always match a preferred style perfectly”, and that advanced chart, shape and formatting edits may be limited. Expect to spend time on either draft.

How much does Copilot cost compared with ChatGPT?

They are priced on different models, and the difference is easy to miss. Microsoft sells Copilot as an add-on. Its business pricing page, read on 5 October 2026, lists Microsoft 365 Copilot Business “originally starting from $21.00 now starting from $18.00 user/month, paid yearly”, and it states that a separate license for a qualifying Microsoft 365 plan is required, for up to 300 users. The same page lists suites with Copilot already bundled at $23.50 and $32.00 per user per month, paid yearly. So a Copilot seat is the suite plus the AI.

OpenAI sells ChatGPT seats on their own. Its business pricing page lists a Business standard seat at $20 per month billed annually or $25 billed monthly, and a premium seat with five times the usage at $100 billed annually or $125 monthly, for teams of 2 to 200. The PowerPoint add-in is included in every plan, and OpenAI’s help center says Free and Go get limited usage while Plus, Pro and Business are subject to the plan’s agentic usage limit. Larger decks and multi-step edits use more of that allowance.

For a US team of ten that already pays for Microsoft 365, adding Copilot Business runs about $180 to $210 a month. Ten ChatGPT Business standard seats run $200 a month on an annual plan. The sticker prices are close. What differs is what else you get: Copilot reaches into Outlook, Teams, Word and Excel, and ChatGPT brings a general assistant that also works with Google Workspace.

How do I add ChatGPT to PowerPoint?

Open PowerPoint, go to Home, then Add-ins, search for ChatGPT, add it, then open ChatGPT from the ribbon and sign in with your OpenAI account. If your company blocks the Microsoft Store, a Microsoft 365 admin can deploy the add-in internally from the manifest file OpenAI publishes, and ChatGPT workspace admins can switch the add-in on in workspace settings. One detail worth reading before you paste client material into it: OpenAI’s help page notes that under Microsoft’s add-in marketplace terms, Microsoft may have the ability to read the content of your PowerPoint files.

Copilot or ChatGPT for a deck built from a report

This is the case that sends most people to this comparison. You have a finished document, a quarterly review, an audit summary, a market study, and it needs to be slides by Thursday.

Copilot handles it through Create a presentation from a file. Microsoft’s support page describes the flow: Copilot first writes an outline you can refine in the chat, then generates the slides, tries to bring across images from the Word document, and works best with Word documents under 24 MB. The file has to be reachable in OneDrive or SharePoint. A PDF is not the documented input, so a report that only exists as a PDF needs converting to Word first.

ChatGPT handles it as a conversation. You attach the document or point it at a connected app, and it drafts slides in the open presentation. It is flexible about inputs and good at restructuring an argument for a different audience. OpenAI’s own advice is to ask for a plan first on larger edits, review claims and numbers before sharing, and duplicate the file first so you can revert.

Both rewrite. Neither keeps a visible link from each slide back to the passage it came from, and that is the gap that matters when a director asks where a number came from.

Where DocSlide fits, and where it does not

DocSlide is not an assistant and it does not edit an open presentation. It does one conversion. Upload a PDF or Word file up to 20 MB, or paste the text, and it writes a deck of 6 to 14 slides built only from that document. It is instructed not to add facts, numbers or names the document does not contain, bullets are drawn from your own wording where possible, and the supporting sentences move into speaker notes. Next to every slide in the finished deck you see the source reference it came from, a section name or a short quote, so checking a figure is a glance. The output is a native .pptx with editable text boxes that opens in PowerPoint, Keynote or Google Slides, so it does not matter which suite your company bought.

Where it loses, plainly: it costs more per person than a ChatGPT Business standard seat, it does not produce chart objects (figures arrive as editable text), it reads roughly the first 60,000 characters of a document, and it will not restyle a deck you already have. If you already pay for Copilot or ChatGPT and build decks from scratch, use what you have. If the weekly job is turning finished reports into decks that have to survive scrutiny, a flat $30 a month converter is the narrower tool for it. The longer write-up of the Microsoft side is on the Copilot alternative page, and the ChatGPT side is on ChatGPT to PowerPoint.

Which one should a team actually buy?

If your company runs on Microsoft 365 and people build decks from scratch several times a week, the Copilot add-on earns its keep, because it also works across Word, Excel, Outlook and Teams. If your team is split between Microsoft and Google, or nobody has a Copilot license, ChatGPT Business is the cheaper way to get an assistant into PowerPoint, and its Google Drive connection means the same seat can build native Google Slides too. If the deck almost always starts as a document someone already approved, compare both against a converter before you buy seats; the cost of retyping and re-checking a rewritten deck usually outruns the license. For the Google side of the same decision, see Copilot vs Gemini for PowerPoint, and if the input is a PDF, PDF to PowerPoint covers that path.
