Home / AI PowerPoint generator
AI PowerPoint generator — with Reveal.js HTML you can keep
People search this phrase wanting two things: a deck drafted for them, and a .pptx they can send. We do both halves — but not in the shape the phrase implies, so here is the shape up front. PPTX, PDF and HTML export are all on Free, with no credit card. AI drafting is the paid half, on Pro and Unlimited; Free has no AI. And what we actually build is a Reveal.js editor — not Microsoft 365, not a PowerPoint clone, and not an Office add-in. If the living file has to stay a .pptx in OneDrive with your macros and IT-managed masters, stay in PowerPoint; nothing below will change that.
The phrase means three different tools
“AI PowerPoint generator” is one search for three products that barely overlap. Working out which one you want takes about a paragraph and saves a signup:
- An add-on that generates inside PowerPoint or Google Slides. You stay in the application you already use, the living file stays .pptx or Google, and the AI arrives as a task pane. This is not what we are. Tools built for it include Plus AI and SlidesAI, and if that is the job they are the honest recommendation.
- A cloud generator with its own player. You prompt, it renders into their format, and you present or share a link — with downloads available on whatever terms that vendor publishes. Gamma and Beautiful.ai are the shape of this, and a hosted card with a good share link is a real product we are not trying to be.
- An editor that exports PPTX without making PowerPoint the source of truth. You author somewhere else, keep an open format, and produce a .pptx when somebody downstream demands that file type. That is us.
So the honest pitch for this URL is narrow: a first draft from AI if you pay for it, every slide by hand if you do not, a .pptx you download either way, and HTML you keep so the talk is not trapped in a player.
How the AI and the PowerPoint file actually work here
- PPTX export is on Free. So are PDF and HTML. No credit card, no watermark, no export cap, no slide limit on the export. The downloadable file is not the upsell.
- AI is optional and paid. Free has no AI — it is unlimited manual decks and every template, and it will not generate anything. AI generation, the Alie assistant and AI images are on Pro and Unlimited only. AI is never required to produce a deck or an export.
- The AI drafts a deck, not a PowerPoint file. A prompt or an outline comes back as a first-pass Reveal.js deck you then edit. Export runs afterwards, from the edited deck, along exactly the same path a hand-written deck takes.
- The native format is Reveal.js HTML. The self-contained bundle is the artifact: host it on your own domain, present it offline from a local file, keep it after a subscription ends. PPTX and PDF are conversions out of it.
- The PPTX is a lossy, text-first conversion. One plain text box per slide on a 4:3 canvas, first line larger and bold. Colours, fonts, backgrounds, images, positioning, fragments, transitions, media and speaker notes do not survive it. It carries the words and the slide order, which is what a hand-off usually needs.
- Export is one-directional — there is no PPTX importer. PPTX comes out; no .pptx goes in. You cannot upload an existing PowerPoint file, you cannot have the AI rewrite one, and you cannot round-trip a deck.
- We are not an Office add-in and not Microsoft 365. No ribbon button, no task pane, no AppSource listing, no VBA, no macros, no IT-managed slide masters, no brand-template enforcement. PowerPoint is Microsoft software; we are not affiliated with or endorsed by Microsoft and we do not clone its interface, its animation model, or its co-authoring.
- No borrowed logos, no partnership badges. We are not an OpenAI or Microsoft partner and we do not display anyone else’s mark as proof. Credit where it belongs on the other side too: Reveal.js is an independent open-source project created by Hakim El Hattab, it is free, and we did not invent it.
Who this is not for
- The living file has to be a .pptx. It sits in OneDrive or SharePoint, it carries macros, it inherits an IT-managed master, and three colleagues edit it in Office. Keep PowerPoint, and add an AI add-on inside it if you want generation there. We would be the wrong tool and we are not going to pretend otherwise.
- You want free AI. Free is manual and unlimited, and it will not generate a 40-slide pitch from a sentence. That is the paid half.
- You want a PPTX importer. Upload a deck you already have and edit or regenerate it here. We do not ship one, and we are not going to describe it as coming soon.
- You need the export to look exactly like the live deck. The PPTX carries text and slide order, not design. Use the PDF for fidelity, or the HTML if you want the deck itself.
- You are shopping for Team seats, SSO, live co-editing or viewer analytics. Not sold here. Hosted slide tools do offer those and offer them well; that is a different trade, not a gap we are pretending away.
- You want Smart Slide auto-layout that rearranges a slide as you type — closer to Beautiful.ai. Or you only want a polished share link, which is Gamma’s strength. We are stronger at files than at hosted cards.
Compared with add-ons and cloud generators
Four rows of this table are things we do not do. A comparison where we win every line is a brochure, and the add-on and hosted-cloud approaches are each better than us at the job they were built for.
| What you want | PowerPoint + AI add-on | Gamma-style cloud generator | AI Slide Generator |
|---|---|---|---|
| Where the living file lives | .pptx or Google Slides, in your own storage. | Their cloud, in their format. | A Reveal.js deck in our editor, exported as HTML you host. |
| AI generation | Yes, metered — check the vendor’s own page. | Yes, usually credits — check the vendor’s own page. | Optional and paid. None on Free. |
| A .pptx you download without paying | You already own the file; the AI is the subscription. | Export is often the paywall — check the vendor’s own page. | On Free. PPTX, PDF and HTML, no card. |
| Generation inside the PowerPoint window | Yes — that is the entire point of an add-in. | No; you work in their editor. | No. We are not an Office add-in. |
| Macros, VBA, IT-managed slide masters | Yes — PowerPoint keeps doing that underneath. | No. | No. We do not implement any of it. |
| Import an existing .pptx and edit it | Yes — it is the same file. | Some offer it — verify on their own docs. | No. We do not ship a PPTX importer. |
| A deck that still opens after you cancel | The file stays; the AI stops. | The link usually stops; check their retention terms. | The downloaded HTML, PDF and PPTX do not check in with us. |
| Team seats, SSO, live co-editing | Not from the add-on — Microsoft 365 or Google Workspace provides it. | Yes, on team plans. | No. Individual plans only. |

FAQ
Are you an AI PowerPoint generator inside Microsoft 365?
No. We do not run inside PowerPoint, we are not an Office add-in, and we are not affiliated with or endorsed by Microsoft. There is no ribbon button, no task pane, no add-in to install from AppSource, and nothing that reads or writes the file open on your desktop. We are a browser-based Reveal.js editor that can write a .pptx file on the way out. If you want AI generation to happen inside the PowerPoint window on a file that stays in OneDrive, an add-in such as Plus AI or SlidesAI is doing that job and we are not.
Does the Free plan include AI?
No. Free has no AI at all — no prompt-to-deck, no Alie assistant, no AI content suggestions, no AI images. What Free is: unlimited manual decks and slides, every template, and PPTX, PDF and HTML export with no credit card. AI generation is on Pro and Unlimited only. This page sits on a keyword that promises free AI PowerPoint generation all over the search results, so the sentence is worth repeating plainly: signing up for $0 expecting the AI half will disappoint you.
Can I export PPTX on the Free plan?
Yes. PPTX export is on Free, and so are PDF and HTML. There is no export paywall, no watermark stamped into the file, no slide cap on the export, and no card to reach it. The paid plans buy AI generation, not the right to download your own deck. The two halves of this product are priced in opposite directions and it is worth saying once more: the PowerPoint file costs nothing, the AI costs money.
What does the AI actually produce?
A first-pass Reveal.js deck from your prompt or outline — slide structure, titles, body text and layout choices you then edit by hand. It is a draft in our editor, not a .pptx that the AI wrote directly and not a rendering locked to a player. Every export runs from the deck after you have edited it, so a generated deck and a hand-written one export through exactly the same path. When your generations run out the editor keeps working: manual editing and export are not metered on any plan.
Is the exported PPTX a faithful copy of my deck?
No. The PPTX is a lossy, text-first conversion out of a Reveal.js deck rather than a re-render of it. The exporter reads the text of each slide and writes it into one plain text box per slide on a standard 4:3 canvas, first line larger and bold. Theme colours and fonts, backgrounds, images, layout and positioning, fragments, transitions, embedded media and speaker notes do not make the trip. You get the words and the slide order in a file PowerPoint opens without complaint. If you need fidelity, send the PDF; if you want the deck that still behaves like a deck, keep the HTML.
Can I upload an existing .pptx and have the AI rewrite it?
No. We do not ship a PPTX importer. There is no upload box that turns a PowerPoint file into an editable deck, no AI pass over a file you already have, no partial conversion, and no round-trip where you export, edit in PowerPoint, and bring the changes back. Export is one-directional: you author here and PPTX comes out. This is the single most common request from people who arrive on a page like this one, so the answer is a flat no rather than a roadmap tease. If converting an existing .pptx is the actual job, PowerPoint itself and the dedicated conversion tools do it properly.
Why does a PowerPoint keyword page keep talking about Reveal.js?
Because that is what we actually build, and hiding it until after you signed up would be dishonest SEO. The deck you edit is a Reveal.js deck, the HTML bundle is its native form, and PPTX is a conversion we run on the way out. Naming the engine up front is also the useful answer: it tells you the deck self-hosts, runs offline from a local file, and does not stop working when a subscription does. Reveal.js is an independent open-source project created by Hakim El Hattab; it is free, we did not invent it, and we claim no affiliation with it.
Do you use ChatGPT, and are you an OpenAI or Microsoft partner?
We are not a partner of, affiliated with, or endorsed by OpenAI or Microsoft, and we do not display partnership badges for either. The AI features on the paid plans are ours to operate and the deck you get back is a draft in our editor; which models sit behind them is an implementation detail we change, not a logo we borrow credibility from. Nothing about Microsoft 365, Copilot or PowerPoint on this page should be read as a relationship with Microsoft.
Do you sell Team seats, SSO, macros, or slide-master governance?
No, none of them. We do not sell Team seats, Enterprise, or SSO, and there is no shared workspace, live co-editing, admin console or export audit log. We also do not implement the corporate PowerPoint machinery people ask about on this keyword: no VBA, no macros, no add-in ribbon, no IT-managed slide masters, no brand-template enforcement, no font or colour policy engine. Free and the two paid plans are individual accounts bought through Stripe, and there is nobody to negotiate with.
Do you publish a rating, a user count, or a number of decks generated?
No. There is no star rating, no rating markup in this page structured data, no logo wall of companies said to use us, no testimonials, and no count of users, decks or AI generations. We are also not going to call ourselves the number one AI PowerPoint generator, because that is a ranking nobody published. The claims here are about what the software does and what it costs, and both are checkable by making a free account or reading the pricing page.
Start on Free and see which half you need
Free is manual and unlimited, and PPTX, PDF and HTML export are all included. No credit card, no AI. Add the paid AI later if the drafting is what you came for.
