Google Slides vs PowerPoint: October 2026 Comparison of AI, Files, Collaboration and Price

Disclosure: NOXI publishes this comparison and appears in it as a third route, not as a contestant, for people who want an AI-designed deck to finish in either editor. Google Slides and PowerPoint are compared only on what Google and Microsoft document on their own pages; the criteria, weights, scoring anchors and every official source are published below so you can check each cell.

Most "Google Slides vs PowerPoint" pages that rank today were written by template shops and AI vendors, and nearly all predate the 2026 changes: Gemini now builds a full multi-slide deck inside Slides (30 June 2026), Copilot in PowerPoint gained custom skills (23 September on the web, 6 October on Windows), and ChatGPT and Claude now run inside PowerPoint. This page compares the two editors on what each vendor states on its own pricing pages, help centres and release notes, opened on 14 October 2026. It is a documented-capability comparison, not a new hands-on test.

The verdict: Google Slides, PowerPoint or both

Google Slides wins when collaboration and cost decide the choice; PowerPoint wins when the .pptx file, offline desktop work or design depth decide it. The one constraint you cannot change should pick the tool, and the table names it.

What changed in 2026: both editors learned to build a deck

In 2026 both editors gained AI that writes a whole presentation, which removes the old argument that PowerPoint had Copilot and Slides had only image generation. The dated changes below come from Google's and Microsoft's own announcement pages and release notes, read on 14 October 2026.

Secondary reports give different general-availability dates for ChatGPT for PowerPoint; OpenAI's own page does not state one, so this page does not either.

How we compared: ten criteria, 100 points, official pages only

Each editor is scored 1 to 5 on ten criteria with published weights, and the total is the sum of weight × score divided by 5, so a perfect sheet is 100. A point is awarded only for a capability Google or Microsoft states on an official page opened on 14 October 2026; "not stated" scores as absent. This is a documented-capability score, not a hands-on test, and the anchors let you re-score any cell.

Why these weights. They describe a working team that builds decks together and sends some of them to other organisations. Files, collaboration and AI drafting carry 45 points because they decide whether a deck can be built and delivered at all. Price carries 20 (the free route plus the cost of AI), and devices, design, presenting and language the last 35. A classroom or a startup that never sends .pptx should re-weight, and the next section does exactly that.

The scoring table: PowerPoint 90, Google Slides 82

On the default weights PowerPoint leads by eight points because .pptx is its own format, it has full offline desktop apps and deeper design tools, and two outside AI assistants are generally available inside it. Google Slides leads on price and collaboration: its free tier is the whole editor, and Gemini comes inside the standard business seat.

Google Slides: (50 + 50 + 60 + 15 + 45 + 75 + 40 + 30 + 20 + 25) ÷ 5 = 410 ÷ 5 = 82. PowerPoint: (40 + 30 + 75 + 25 + 75 + 60 + 50 + 50 + 20 + 25) ÷ 5 = 450 ÷ 5 = 90.

Re-weighted for a classroom or a collaboration-first startup

The order flips when the .pptx file stops mattering. Set the free route to 25, collaboration to 25, the cost of AI to 15, AI generation to 10, every other criterion to 5 and third-party AI to 0. Google Slides then scores (125 + 75 + 40 + 0 + 15 + 125 + 20 + 15 + 20 + 25) ÷ 5 = 460 ÷ 5 = 92, and PowerPoint (100 + 45 + 50 + 0 + 25 + 100 + 25 + 25 + 20 + 25) ÷ 5 = 415 ÷ 5 = 83. Neither editor is better in general; each is better for a stated set of priorities, which is why the weights are published.

Google Slides vs PowerPoint: the facts side by side

This is the table to bookmark: eleven rows, each a fact Google or Microsoft states on its own page on 14 October 2026, so you can see why every score above is what it is.

Gemini in Google Slides vs Copilot in PowerPoint

Gemini in Google Slides and Copilot in PowerPoint both draft a complete deck from a prompt and show a plan before building it. Copilot reaches more platforms and languages; Gemini costs less for a business team because it is included in the standard seat.

What Gemini in Slides documents

You describe the deck in the side panel, answer or skip Gemini's follow-up questions, review a plan with an overview, a sources list and a slide-by-slide outline, edit it, and approve; generation can take a few minutes with the tab open [3]. Gemini can search the web, Drive, Chat and Gmail, depending on your source settings, and you can pick an existing deck from Drive so the new one mirrors its look [3]. The July update added natural-language edits to layouts, colour schemes, generated charts and text on specific slides [2]. Google's help centre states the limit plainly: the feature is "currently available on desktop and in English only", and the launch post said English (United States) only [1][3]. It needs an eligible Workspace or Google AI plan, and Google said per-user usage limits apply after the launch promotion that ran through at least 1 August 2026 [1].

What Copilot in PowerPoint documents

Copilot creates a presentation in Agent Mode from your prompt: it may ask clarifying questions, builds an outline you can refine, then generates slides [6]. It can also build a deck from a Word document (best under 24 MB, where Word styles map to slides) or start from your organisation's template so the theme and layouts are kept; with a work licence it can also use a PDF, and organisation branding is only for users licensed with Microsoft Copilot [6][7]. Copilot runs in PowerPoint for Microsoft 365 on Windows and Mac, on iPad, and in the Copilot web app with a work or school account; it needs an internet connection and supports one output language at a time [6][7]. Custom skills arrived on the web on 23 September and on Windows on 6 October 2026 [5].

Which AI should decide it?

For an English-language team on Google Workspace, Gemini is the cheaper route to AI drafts because no add-on is needed. For non-English decks, iPad users or teams that need the organisation's PowerPoint template applied by the AI, Copilot's documented reach is wider. Our comparison of Copilot, Gemini and ChatGPT for presentations goes deeper into prompts and output, and AI for Google Slides covers Gemini step by step and the Slides add-ons.

Both editors now accept outside assistants too. ChatGPT for PowerPoint lives in a PowerPoint sidebar and is available on every ChatGPT plan from Free upwards, with limited usage on Free and Go [8]. Claude for PowerPoint reads the slide master, layouts, fonts and colours and runs on PowerPoint on the web, Windows and Mac [9]. On the Google side, Claude for Google Workspace builds slides with the deck's existing layouts and themes, in public beta since 6 October 2026 [10]. Our ranking of AI add-ins for PowerPoint compares them.

The .pptx round trip: what changes in Google Slides

Google Slides can open and edit a PowerPoint file directly, without making a copy, or convert it into a Slides file; on conversion, Google documents that embedded charts and videos become images, SmartArt becomes Google Drawings and macros are not supported. A deck that must return to PowerPoint intact is safest kept as a .pptx throughout.

Google's help centre lists .ppt, .pptx, .pptm, .pps, .ppsx, .ppsm, .pot, .potx, .potm and .odp among the presentation formats that convert to Slides, and .pptx as the format you can save back to [11]. Google Drive caps a presentation converted to Slides at 100 MB [12]. In Chrome, Office editing works through the Office Editing extension, and password-protected .pptx files can be opened, though not legacy binary .ppt files [11]. Google's pages do not list what happens to fonts or animations on conversion, so check those by eye.

If you want to leave PowerPoint altogether, our ranking of PowerPoint alternatives scores fifteen editors and AI tools on the same round trip.

Collaboration: real-time co-editing in both, with different setup

Both editors support real-time co-editing, comments and version history; Google Slides does it in every file with no setup, while PowerPoint needs the file saved in OneDrive or SharePoint first. That single setup step is why Slides scores 5 and PowerPoint 4 on this criterion.

In Slides, "co-editing means that multiple people can work on the same slide at the same time", sharing controls who can view or edit, and version history lets you see who changed what, name up to 40 versions and restore any of them [14][15]. In PowerPoint, colleagues work concurrently once the presentation is saved to OneDrive or SharePoint; comments can be replied to and resolved, tasks can be assigned, and an @mention emails the person a link to the comment [23]. Revision highlighting needs PowerPoint for the web or recent Microsoft 365 builds, and chat with current editors is listed for Microsoft 365 only [23]. For a team that already shares files in Drive, Slides removes a step; for a team on SharePoint, the difference is small.

Offline and devices: desktop apps vs the browser

PowerPoint has full desktop apps for Windows and Mac in its paid plans, which work without a connection; Google Slides has no desktop app and works offline in Chrome or Edge with the Google Docs Offline extension, or per file in its mobile apps. AI drafting needs a connection in both.

Google's conditions for offline Slides are specific: you must be online to switch it on, use Chrome or Microsoft Edge (not private browsing), install the Google Docs Offline extension, and only one account per browser profile can be offline; administrators can turn it off [13]. On Android you tap "Make available offline" per file, or make recent files available automatically [13]. Microsoft lists desktop versions of PowerPoint in Business Standard and Business Premium and in Microsoft 365 Personal, Family and Premium, while Business Basic and the free web route are web and mobile only [21][22]. Copilot in PowerPoint and Designer both need an internet connection [7][25].

Design and animation depth

PowerPoint documents more design depth: Designer suggests layouts (free on the web, a subscriber feature on desktop), and the Morph transition animates objects between slides on desktop, web and mobile. Google Slides offers themes, layouts and templates, with Gemini generating slides and images.

Microsoft says that on PowerPoint for the web "design suggestions are available to everyone", that Designer is a subscriber feature on Windows and Mac, and that it needs a connection because it goes online for ideas [25]. Morph can be created in Microsoft 365 on Windows and Mac, PowerPoint 2019 and 2021, the web and the mobile apps; on the web it needs files stored in OneDrive for work or school, and creating one on mobile needs a subscription [24]. On the Slides side, Google's product page lists templates, themes and Gemini generation from a prompt and your Drive content [14]. If your deck must follow a corporate slide master, see our guide to AI presentations in your own template.

Price: free routes, team seats and the cost of AI

Both editors are free for individuals: Google Slides with a Google account, PowerPoint for the web with a Microsoft account. For teams, both Business Standard seats list at $14 a user a month on annual commitment; the difference is AI, which Google includes and Microsoft sells as a $23.50 bundle.

Caveats. Google's public pricing page shows the visitor's local currency and time-limited introductory discounts for new customers: opened from the United Arab Emirates it showed Business Standard at €13.60 on annual commitment and €16.20 flexible. The US dollar figures above come from Google's own admin help page on payment plans [18]. Microsoft's Copilot Business add-on was shown at $18.00, reduced from $21.00, as an offer [21]. All prices are list prices before tax.

Individuals see the opposite pattern. A freelancer who wants AI deck drafting on a personal account pays $239.88 a year for Google AI Pro or $99.99 for Microsoft 365 Personal, which also includes desktop PowerPoint and 1 TB of storage [19][22]. Students and teachers on free accounts get both editors at no cost; AI drafting in either needs a paid plan or a school licence. Our guide to AI presentation tools for teachers lists the free routes for classrooms.

Which editor for which job

The fastest way to decide is to name the deck you build most often. Each row picks from the documented capabilities above; the second choice is the one to try if the first does not fit your budget or workflow.

Arabic and other right-to-left decks in both editors

Google Slides and PowerPoint both support right-to-left text for Arabic and Hebrew with a paragraph direction control; the difference is AI drafting, which Gemini in Slides offers in English only, while Copilot in PowerPoint lists many languages with one output language per deck.

In Slides, right-to-left controls turn on automatically when a presentation contains right-to-left text, or you can switch them on in Settings; then you select the text and click Paragraph direction on the format toolbar [17]. In PowerPoint, the Right-to-left button sits in the Paragraph group on the Home tab once a right-to-left language is enabled, and you add Arabic under File, Options, Language, plus a matching keyboard [28]. Microsoft notes that Copilot works in many languages with the best quality in English [7]. For a deck that must work in Arabic and English at once, see our guide to the bilingual Arabic-English presentation.

What about Keynote and Canva?

Keynote is the free third editor for Apple users: it imports and exports PowerPoint files and collaborates in real time through iCloud, with no subscription needed for creating, viewing and editing. Canva is a design suite rather than an office editor, and is compared with AI tools in a separate article.

Keynote runs on iPhone, iPad, Mac and Apple Vision Pro, and on a PC through iCloud.com; an optional Apple Creator Studio subscription at $12.99 a month or $129 a year adds premium themes and AI image tools [29]. Apple's compatibility table says unsupported fonts are substituted, most PowerPoint transitions are supported, SmartArt arrives as a plain shape, and some chart types are converted [29b]. For Canva and the AI-first makers, see Gamma vs Canva vs Beautiful.ai.

A third route: an AI-designed deck that opens in either editor

A third route is to design the deck with an AI presentation maker and bring the finished file into whichever editor your audience uses. NOXI, the publisher of this page, is one such maker: it builds the deck from a prompt or your files and exports an editable PowerPoint (.pptx) and PDF.

• Free. No card and no watermark; each account gets 1,000 credits a month and a full deck uses about 25, so about 40 decks a month (1,000 ÷ 25).
• From your material. Upload a PDF, Word document, Excel or CSV file, PowerPoint or image, and NOXI turns it into a structured deck; when you start from a prompt, it researches the topic on the web first and slides with figures carry a source line.
• In your style. Upload any PowerPoint, PDF or even an image as a reference, and NOXI designs the new deck in that style: colours, typography, layouts and visual rhythm.
• The file. An editable PowerPoint with real text boxes and embedded fonts, Arabic included, that opens in PowerPoint; to keep working in the browser, upload it to Drive and open it in Google Slides.

Whichever tool made a .pptx, run the six-point check in the round-trip section after you open it in Google Slides.

Key terms used in this comparison

Four terms carry most of the weight in this comparison. Each is defined so the scores can be read the same way by everyone.

What this comparison does not measure

A documented score tells you what each editor is built to do, not how good the AI's first draft is, how long generation takes, or how a particular deck converts. Those need the same brief and the same .pptx run through both editors. Nor does it weigh security reviews, data residency or admin controls, which enterprise buyers should read on each vendor's trust pages. Before you move a whole team, convert your three most complex decks and check them with the six-point list above.

Three prompts for a deck that works in either editor

The three prompts below build the deck in NOXI and hand it to PowerPoint or Google Slides at the end. Replace the bracketed parts with your own details.

Build it in NOXI: six steps

Each step uses a documented NOXI capability, and the whole deck stays inside the free monthly allowance.

Frequently asked questions

Is Google Slides better than PowerPoint?

It depends on what you weigh. On ten documented criteria with weights for a working team that sends .pptx files, PowerPoint scores 90 and Google Slides 82. Re-weighted for a classroom or a collaboration-first startup that never sends .pptx, Google Slides scores 92 and PowerPoint 83. Slides wins on price and co-editing; PowerPoint wins on the file, offline desktop work and design depth.

Is Google Slides free?

Yes. Anyone with a Google account can create in Google Slides at no cost, with 15 GB of storage shared across Gmail, Drive and Photos. Some features, such as Slides recording and speaker spotlight, need a Google Workspace plan, and Gemini's full-deck generation needs an eligible Workspace plan or a Google AI plan such as AI Pro at $19.99 a month.

Is PowerPoint free?

PowerPoint for the web is free with a Microsoft account and includes real-time collaboration and 5 GB of OneDrive storage. The desktop apps for Windows and Mac come with paid plans: Microsoft 365 Personal at $99.99 a year, which includes Copilot, or Business Standard at $14 a user a month paid yearly, which does not include Copilot in the apps.

Can Google Slides open PowerPoint files?

Yes. Google Slides can edit a .pptx directly without making a copy, or convert it, along with .ppt, .pptm, .pps, .ppsx, .ppsm, .pot, .potx, .potm and .odp, into a Slides file of up to 100 MB. On conversion, Google says embedded charts and videos become images, SmartArt becomes Google Drawings and macros are not supported. You can download the result as .pptx.

Does Google Slides work offline?

Yes, with conditions. On a computer you need Chrome or Microsoft Edge, the Google Docs Offline extension and an internet connection to switch offline access on; only one account per browser profile can be offline, and admins can disable it. In the Android app you tap "Make available offline" for each presentation or for recent files. Google Slides has no desktop app.

Which is better for students, Google Slides or PowerPoint?

For group projects, Google Slides: it is free, several students can edit the same slide at once, and version history shows who changed what. PowerPoint for the web is also free and collaborates in real time once the file is saved in OneDrive. Choose PowerPoint when a teacher requires a .pptx submission or the school runs on Microsoft 365.

Which is better for teachers?

Google Slides has audience Q&A with voting and English captions built into presenting, and needs no file setup for shared lesson decks. PowerPoint offers live subtitles in 63 languages, Morph and Designer, and suits schools on Microsoft 365. Both are free for the basic editor; AI drafting in either needs a paid or education plan.

Does Google Slides have AI like Copilot?

Yes. Since 30 June 2026, Gemini in Google Slides creates a full multi-slide presentation from one prompt, using Drive files, the web, Gmail and Chat as sources and an existing deck as the style, with an outline to review first. Google says it is currently available on desktop and in English only, on Business and Enterprise Standard and Plus, Google AI Pro and Ultra, and some education plans.

What is the difference between Google Slides and PowerPoint?

Google Slides is a browser-first editor built for live co-editing, free with a Google account and stored in Drive. PowerPoint is a file-first editor whose native format, .pptx, is the standard for exchanged decks, with full desktop apps, Morph and Designer. Both now have AI that drafts whole decks: Gemini is included in Google's standard business seat, Copilot costs extra on Microsoft's.

Google Slides vs PowerPoint vs Keynote: which should I use?

Use Google Slides for browser-based teamwork at no cost, PowerPoint when decks travel as .pptx files or you need desktop features, and Keynote if you work only on Apple devices. Keynote is free to create and edit, imports and exports PowerPoint files, and collaborates through iCloud, but Apple notes that unsupported fonts are substituted and SmartArt arrives as a plain shape.

Sources & methodology

How this comparison was made: Google Slides and PowerPoint were scored on ten weighted criteria from Google's and Microsoft's official pricing pages, help centres, release notes and announcements, plus OpenAI's, Anthropic's and Apple's own pages for the add-ins and Keynote, all opened on 14 October 2026; pages that render by script were opened in a browser. Scores credit documented capability only and are editorial judgements by NOXI, which is not scored. The consultancy in the price section is a fictional example. Prices are list prices as displayed and change often.
