AI Tools for PowerPoint in 2026: What Each Plan Actually Lets You Export

Every AI tool for PowerPoint sells the same promise, and it is always about the front of the process. A finished deck in 90 seconds. Ten slides from one prompt. Structure, copy and design handled while you make coffee.
Few of them sell you on what happens after export, which is where the outcome is decided.
You are probably not presenting from their app. You are sending a file, and somebody who is not you is going to open it, change a number and move your logo. What that file looks like when it lands, and whether the plan you paid for even produces it, decides whether any of this saved you time.
Our view, after reading every pricing page in this comparison: “exports to PowerPoint” is close to a meaningless claim. It appears on nearly all of them and it means at least 4 different things, only one of which is any use to you. Which of the 4 you get is decided by your plan tier more often than by the product, and the free tier rarely includes the one you want.
So this page answers a narrower question than most articles with a similar title. It does not tell you which tool designs the nicest slide. It tells you which plan produces a file you can send, what that costs at 1 seat and at 10, and which claims on those pricing pages do not survive being checked. If you want a visual bake-off, several competitors have run one and we link to them below.
What we did, and what we have not done yet
We read the pricing page, help centre and export documentation for every tool below on 8 August 2026, and linked each figure at the point of the claim.
That surfaced 3 things nobody else in this category has published. A Beautiful.ai export menu shipping an editable and a non-editable PowerPoint option under near-identical names. A Gamma slide limit where the vendor’s documentation and every third-party guide disagree. And a widely cited comparison still running a Pitch plan that no longer exists.
What we have not done is run the same deck through all 4 tools and measured what breaks on export. Several competitors have, and their screenshots are worth looking at even though their leaderboards are not. So this article makes no first-hand claim about export fidelity. The protocol we intend to run is published at the end, written so you can run it against your own template rather than waiting for ours.
Of these 4, the cheapest unbranded PPTX costs $144 a year
Among standalone tools that is Beautiful.ai Pro, then Pitch Plus at $156. Microsoft 365 Copilot is a different route rather than a third price, working inside PowerPoint instead of exporting to it, at $216 on top of a qualifying base licence. No free tier in this comparison produces a PowerPoint file you can send to a client.
| If you need | Start with | Per year |
|---|---|---|
| Others to edit the file | Microsoft Copilot | $216 + licence |
| The cheapest clean PPTX | Beautiful.ai Pro | $144 |
| To see who opened it | Pitch Plus | $156 |
| A fast draft, file second | Gamma | Not verified |
| One deck, no subscription | Beautiful.ai single | $45 one month |
Copilot is the odd one there. It is an add-on rather than a product, so a qualifying Microsoft 365 licence sits underneath that $216, and the rate is promotional. Everything below is why.
What we graded on
Export state. Which of the 4 export states the plan actually produces, not whether the tool claims PowerPoint export.
Price verifiability. Whether a figure exists on a page the vendor controls, and whether we read it on the verification date.
Cost at team scale. The solo price is the number every roundup prints and the least useful one, because the cheap tiers here are single-member plans.
Where editing ends up. Who can change the file after you send it, and what they need installed to do it.
Each tool below is graded against these four, in the same order, and every section ends with the one that decided it.
Why Canva, Plus AI and SlidesAI are not here
Canva, Plus AI and SlidesAI are reasonable tools that belong in a wider roundup. They are absent here because we did not open their pricing pages on the verification date, and this article prints no figure we have not read.
The same applies to Alai, Chronicle, Prezi, STORYD and Presentations.AI. Competing comparisons cover 12 to 17 tools. We cover 4, one per route, and would rather be checkable on 4 than approximate on 17.
The 4 things “PowerPoint export” can mean
The weakest is no export at all, where the plan never produces a PPTX. Above that sits branded export, where a file exists but carries a vendor badge, which rules it out for anything client-facing.
Then unbranded export, a clean file with no vendor mark, usable if it opens correctly. And at the top, unbranded and editable, where text, charts and tables arrive as objects rather than as flattened pictures of themselves, so the file survives the next person who opens it.
Only the last is worth paying for, and it is the only one a pricing page cannot confirm. The first 3 are readable off any vendor’s plan comparison. Editability is not, which is why it has the test protocol at the end of this article rather than a confident sentence here.
Where the line falls on each tool
Read from each vendor’s own page on 8 August 2026.
Start with the free tiers, because that is where the pattern is clearest. Beautiful.ai does not have one, only a 14-day trial that takes a card and charges in full if you forget to cancel. Pitch’s free plan produces no PowerPoint file at all and brands its PDFs. Gamma does export PPTX free, with a “Made with Gamma” badge on it. And Copilot Chat, the free Microsoft tier, does not include Copilot inside PowerPoint at all.
Four vendors, four different ways of not giving you the thing. If your plan is to evaluate these on their free tiers, you will be evaluating three products with the feature removed and one that is not the product.
The first paid tier is where it resolves, and it resolves differently for each. Beautiful.ai Pro at $12 gives you an unbranded export that its documentation says stays editable, alongside a second export in the same menu that does not. Pitch Plus at $13 gives you a clean PPTX. Gamma’s paid tiers drop the badge. Copilot Business skips the question, because a native file was never exported in the first place.
Team tiers inherit whatever the tier below unlocked, so nothing new happens there except the price, which is covered further down. One thing worth knowing: Beautiful.ai is the only tool here selling a single presentation, at $45 with Pro rights, for people who need one good deck and not a subscription.
Where our evidence stops
We read 3 of those 4 prices off a vendor-controlled page on the verification date: Beautiful.ai Pro at $12 a month billed annually, Pitch Plus at $13, and the Copilot Business add-on at $18 promotional against $21 list. Gamma we did not, so no Gamma figure appears anywhere on this page.
Export availability we confirmed for all 4. Editability is where it thins out. Beautiful.ai documents it explicitly in its support articles, on Pro and above and only through one of two similarly named export options. Pitch and Gamma say nothing either way. Copilot does not need to, since the file is native.
Export fidelity we have tested for none of the 4, and that stays true until we run the test protocol at the end. A claim a vendor documents and a claim someone has checked are different things, which is the argument this whole page rests on.
Best for files other people will edit
Microsoft Copilot in PowerPoint
Pros
- The file is a PPTX from the first keystroke, so no conversion step exists
- Applies an existing slide master rather than imposing its own theme
Cons
- Cannot be bought alone; requires a qualifying Microsoft 365 licence underneath
- Capped at 300 users, above which enterprise licensing applies
If your company runs on Microsoft and your brand template lives in a slide master someone in marketing guards carefully, most of the tools in this comparison are going to fight you. Copilot does not, because it never asks you to leave.
Copilot’s primary workflow is native PowerPoint. It drafts, rewrites and summarises inside the application and produces a PPTX because the file never was anything else. Beautiful.ai also offers an add-in that runs inside PowerPoint, but slides saved through it are not editable there, so Copilot is the only one of the 4 where native and editable are the same thing.
Understand the cost structure before anything else. Copilot Business is an add-on rather than a product, and it caps at 300 users. Microsoft lists it at $21 per user per month paid yearly, discounted to $18 under a promotion running 1 July to 30 September 2026 that covers the first year only. Paying monthly costs $25.20 per user, a 20% premium over the list annual rate.
If you would rather buy base plan and Copilot as one line item, the same page prices Business Standard with Copilot at $23.50 per user per month paid yearly and Business Premium with Copilot at $32.00. Enterprise licensing sits outside the business plans and starts with a Microsoft representative rather than a checkout.
Where Copilot is weak is where every AI slide tool is weak, and this part is our judgement rather than anything on a pricing page. It produces serviceable structure and flat proof. It will not know which number is the one that wins the room. Budget human time for the argument, not the layout.
What decided it: where editing ends up. Copilot is the only tool here where the file never becomes something else, so nothing has to survive a conversion. That is worth the licensing complexity when the deck goes to someone who will change it, and worth little when you are the only editor.
Copilot price: $18 per user per month promotional, $21 list, billed annually, plus a qualifying Microsoft 365 licence.
Best for recurring decks, and for a single deck you do not want to subscribe for
Beautiful.ai
Pros
- Smart Slides hold alignment without you managing it
- A $45 single-presentation option, which no other tool here publishes
Cons
- No permanent free tier, only a 14-day trial that requires a card
- Teams pricing is the most expensive per seat in this comparison
If you build the same deck every month and spend the first hour nudging boxes back into alignment, this is the tool that takes the nudging away from you, whether you wanted it taken or not.
Beautiful.ai automates layout through Smart Slides, which apply alignment and spacing rules as you add content. That constraint is the product. It is why decks stay consistent without a designer, and why unusual custom layouts are harder here than in a free-form editor.
Pro is $12 per user per month billed annually, which is $144 a year, and the same page lists editable PowerPoint export and PowerPoint import on that tier. Teams is $40 per seat per month billed annually or $50 billed monthly, for 2 to 20 seats, which is where this tool becomes expensive relative to everything else here.
Two things on that page are easy to miss. There is no permanent free tier, only a 14-day trial that requires a card and charges in full if you do not cancel. And a $45 single-presentation option sits below the main plan cards, billed monthly with Pro rights, which is the honest choice for a genuine one-off.
Beautiful.ai ships 2 PowerPoint exports, and one of them is a trap
Beautiful.ai’s two-export split is the single most useful thing we found while checking this article, and it is the reason “exports to PowerPoint” is a meaningless phrase on its own.
Editable PowerPoint produces a PPT in which, per Beautiful.ai’s support documentation updated on 3 August 2026, every element remains editable inside PowerPoint, speaker notes included. It is available on Pro, Team and Enterprise only, and exports either a single slide or the whole deck.
PowerPoint images produces a PPT whose slides are static pictures of your content. The same documentation states plainly that the download will not be editable. It only works on a whole presentation.
Both options live in the same export menu. Pick the wrong one and you hand over a deck nobody can change, which is exactly the failure the phrase “PowerPoint export” is supposed to warn you about and does not.
A third route has the same problem. The PowerPoint add-in lets you build Beautiful.ai slides inside PowerPoint, but the documentation says slides saved that way cannot be edited in PowerPoint; you reopen them in the Beautiful.ai editor instead.
One detail worth carrying into any export from any tool: the editable export instructions warn that if your machine lacks the fonts used in the deck, the exported file will differ, and offer a font download step first. That is font substitution stated by a vendor rather than inferred by us.
What decided it: export state. Beautiful.ai is the only tool in this comparison whose documentation states outright that its PowerPoint export stays editable, and the only one shipping a second export in the same menu that does not.
Beautiful.ai price: $12 per user per month billed annually. Teams $40 per seat. Single presentation $45.
Best for sales teams who need to know who opened the deck
Pitch
Pros
- Per-slide engagement analytics, so you know where attention stopped
- Commenters count as free roles inside the member cap
Cons
- Free plan has no PPTX export at all
- The annual saving is mislabelled on the entry tier
You sent the deck on Tuesday. It is now Friday and you have no idea whether anyone opened it, let alone whether they made it past the pricing slide. Pitch is built for that specific anxiety.
Pitch is built around what happens to the deck after it leaves the editor: real-time co-editing, slide assignments, and analytics showing which slides a viewer actually spent time on. Its AI layer generates on-brand slides and personalises messaging across variants, which is why it indexes toward sales teams shipping many versions of one story.
The plan structure as published on 8 August 2026 runs Free for up to 5 members, then Plus at $13 a month billed yearly for a single member, Team at $19 per seat for up to 25, Business at $25 per seat for up to 200, and Enterprise above 30. Monthly billing adds roughly $2 to $5 per seat depending on tier. Prices exclude VAT, and overage credits run $0.004 each.
Two things on that page are worth checking yourself, and both are the kind of detail a comparison table would hide.
The free plan has no PPTX export at all. Not branded, not watermarked, none, which makes its generous 5-member allowance misleading if a file is what you need rather than a link.
And the yearly toggle is labelled “Save 17%”. That holds for Team, where $19 against $23 is 17.4%, and for Business at 16.7%. It does not hold for Plus, the tier most individuals will land on, where $13 against $15 saves 13.3%.
The same page’s FAQ still answers a question about the difference between “Free, Pro, and Business” while the plan cards above it read Free, Plus, Team and Business. A small thing, but it tells you how fast this category renames itself.
What decided it: cost at team scale. Pitch is the cheapest option here at every seat count above one, and the gap widens as the team grows. Its free tier is the trap: generous at 5 members, and no PowerPoint file at all.
Pitch price: $13 per user per month billed annually on Plus, $19 per seat on Team, excluding VAT.
Best for fast drafts where the deliverable is a link
Gamma
Pros
- Fastest route here from a paragraph of text to something that looks designed
- PPTX export available on every tier, including free
Cons
- Free-tier credits do not refresh at all
- We could not verify a current price from a Gamma-controlled page
It is 9pm, the deck is due tomorrow, and you have a paragraph of notes. Gamma is the tool most likely to turn that into something presentable before you finish your coffee, with a catch that arrives later.
Gamma turns a paragraph into a designed deck faster than anything else here, and its card format is genuinely different from a slide grid, which is both the appeal and the export problem. Cards expand to fit their content. PowerPoint slides do not. Something has to resolve that at export, and what gets resolved is what the fidelity test measures.
Two mechanics matter more than the tier list, and both come from Gamma’s own documentation.
The first is that credits are consumed by AI actions, and Gamma states that consumption varies by action, model and length. A credit allowance therefore does not convert cleanly into a number of finished decks.
The second is that free-plan credits do not refresh at all. You top up by referring someone, at 200 credits each, or by upgrading. That makes the free tier an extended trial rather than a plan. On paid plans unused credits roll over up to double the monthly allowance, and only paid subscribers can buy more.
On export specifically: PPTX export is available including on the free tier, but free-tier output carries a “Made with Gamma” badge that paid tiers remove. Available and usable are not the same thing, which is the distinction this whole article turns on.
Gamma publishes a pricing page at gamma.app/pricing, which its help centre links to repeatedly. We did not read that page on the verification date, so this article prints no Gamma figure. The help centre article itself describes all 6 tiers and carries no dollar figures at all.
A second disagreement is worth recording, and it is not about price. Gamma’s help centre states that the Free plan generates up to 10 slides in a single prompt, and that Plus, Pro and Ultra each generate up to 75.
Third-party guides published this year report a different ladder: 10 on Free, 20 on Plus, 60 on Pro, 75 on Ultra. They agree with each other and disagree with the vendor. The vendor page is the one to trust, but it is worth knowing that the Plus figure every comparison article repeats is not the figure Gamma publishes.
What decided it: price verifiability. Gamma is the one tool here we cannot price from a page we read, so it is the one tool here we cannot judge on cost. Use it for first drafts and link-shared decks, and open the checkout page yourself before committing.
Gamma price: not verified. Open gamma.app/pricing before you buy.
What it costs as the team grows
Per-user prices are not the number to budget on, because the cheap tiers at Beautiful.ai and Pitch are single-member plans. Adding one colleague moves you to a team plan, and the team plans are where these 4 separate sharply. All figures below are annual billing, our arithmetic from the rates linked above.
| Seats | Beautiful.ai | Pitch | Copilot add-on | Copilot all-in |
|---|---|---|---|---|
| 1 | $144 | $156 | $216 | $282 |
| 5 | $2,400 | $1,140 | $1,080 | $1,410 |
| 10 | $4,800 | $2,280 | $2,160 | $2,820 |
Beautiful.ai figures are Pro at one seat and Teams above it; Pitch is Plus then Team. The Copilot add-on column is the promotional rate; the all-in column adds Business Standard underneath it.
The shape of that table is the finding. At one seat the priced options are close enough that workflow should decide, not headline price. At 10 seats Beautiful.ai costs $2,520 a year more than Pitch for the same headcount, and more than the fully licensed Microsoft option that produces PPTX natively. If you are evaluating on the solo price and rolling out to a team, you are evaluating the wrong number.
Copilot sits in two columns because the add-on cannot be bought alone. The add-on column leaves out the base Microsoft 365 licence it requires, so the bundled column next to it is the honest all-in figure, and neither is equivalent to a standalone presentation subscription.
Two more things that table hides. The promotional $18 rate covers the first year only, after which the add-on column rises to $2,520 at 10 seats. And Pitch counts commenters as free roles inside the member cap, so 10 people in a Pitch workspace is not necessarily 10 paid seats.
The tool most 2026 roundups still recommend does not exist
Tome’s presentation product is gone. Forbes reported in July 2026 that founder Keith Peiris shut it down in March 2025 and laid off most of a 70-person team, later launching a sales tool called Lightfield. Revenue had plateaued around $3 million despite heavy usage.
Secondary accounts put the final shutdown at 30 April 2025 and say decks not exported before that date were deleted. We could not confirm either against a Tome announcement still online, so treat the March decision as established and the April date and the deletion as widely reported but second-hand.
Tome still turns up in roundups published in 2026, including, until this rewrite, an earlier version of this page.
The second detail matters more than the shutdown. We found no evidence Tome ever shipped PowerPoint export at any plan level. Its documented output was a read-only web page or a PDF, and the missing PPTX is named repeatedly in contemporary coverage as the reason people left.
Tome’s own documentation is no longer online to check against, so that comes from the coverage rather than the vendor. Either way, recommending Tome to anyone who needed a PPTX was wrong before the shutdown happened.
That was our mistake, and we are flagging it rather than deleting it.
Why we do not score these tools out of 10
Of the comparison articles we read while checking this one, 4 of the most visible were published by companies selling a tool they were ranking, and in each the house tool came first. The testing inside them is often real and the screenshots are useful. The leaderboard is marketing.
Take their evidence, ignore their podium, check every price yourself. We went through this properly in the AI presentation roundups grading their own homework, including 5 pricing contradictions inside one article.
Prices go stale faster than roundups get updated. Here is a dated example you can check in a minute. A widely cited 17-tool comparison published on 27 May 2026 lists Pitch as offering a “Pro” plan at $20 a month with 2 seats included. Open pitch.com/pricing today and there is no Pro plan at all. That comparison was 10 weeks old when we checked it. Any price you read anywhere, this page included, needs a date attached to be worth anything.
4 checks you can run on any tool
The full protocol is at the end of this article. If you have 5 minutes rather than an afternoon, or you are evaluating a tool that launched after this page was written, these 4 checks separate the useful from the demos.
- Look at the first slide before anything else. Does it establish a specific claim, or open with a generic title and a stock image? A tool that cannot open a deck will not close one.
- Find a number in the output and try to verify it. A statistic with no source, or no statistic at all, tells you what kind of content you are being handed.
- Read the speaker notes on any slide. Delivery guidance and transitions are useful. “Discuss the key points on this slide” is filler dressed as a feature.
- Export to PPTX and open it in desktop PowerPoint. Check whether fonts changed, whether elements moved, and whether anything vanished. Do this on day 1 of a trial, not the night before you present.
The brief to slides workflow
The tool matters less than what you hand it. This is the sequence we use, and the first two steps account for most of the quality difference between a deck that works and one that merely exists.
Write a real brief before you open anything. Audience, the one thing they should do or believe, the proof that earns it, one action. Four lines. Every tool here produces better output from a brief than from a topic, and none will ask you for one.
Build the slide map before any slide copy exists. 10 to 14 titles, 2 or 3 points under each. Fixing the argument here costs minutes rather than an afternoon of re-cutting finished slides.
Write titles that make the claim, not titles that name the topic. “Q3 Results” is a label. “Q3 revenue grew 18% on two accounts” is a claim. If a reader flipped through your deck reading only the titles, they should get the whole argument. This is the highest-leverage habit in presentation writing and no AI tool does it by default, because a claim requires knowing which fact matters and the tool does not.
Assign a visual to each slide as part of the map. Chart, diagram, screenshot, icon list. A slide with no assigned visual is usually a slide with no point, and spotting that before you build it is free.
Draft with AI, then supply the proof yourself. These tools generate structure well and evidence badly. Treat every generated figure as a placeholder until you have checked it.
Cut any slide carrying two ideas into two, or drop one. A model asked for 10 slides will pack the 11th idea into the 10th rather than argue with the count.
Finish in PowerPoint if a file is the deliverable, and check contrast on a projector or a bad screen rather than your own monitor.
Read the deck aloud once before you send it. Transitions that look fine on a page fall apart when spoken.
Open the finished file on a different device. Font substitution does not announce itself, and at least one vendor in this comparison warns about it in its own export instructions.

How to test PPTX export fidelity yourself
Some roundups in this category do test exports and do show the output, which is more than we can currently say. What almost none of them do is publish a protocol you can rerun against your own template. Here is ours, written so you can run it in an afternoon.
Build one control deck of 12 slides and use identical content in every tool. Include the 6 things that break: a title slide with a custom font, a two-column text slide, a bar chart built from pasted data, a table with more than 4 columns, a full-bleed image with text over it, and a logo placed against a coloured background.
Export each version to PPTX and open all of them in desktop PowerPoint rather than the web version, because the web version substitutes fonts differently.
Then score each deck on 6 things you can count, plus the one that converts them into a cost. Copy these into a spreadsheet with a column per tool.
| What to count | How to record it |
|---|---|
| Editable slides | Count out of 12 |
| Font substitutions | Number of text boxes |
| Chart survived | Chart or image |
| Table structure | Intact or collapsed |
| Vendor branding | Present or absent |
| Visual fidelity | Score 1 to 5 |
| Cleanup time | Minutes |
A slide counts as editable when it arrives as objects rather than as a flat picture. Visual fidelity scores spacing, hierarchy, cropping and alignment against the original. Cleanup time is measured to the point where you would send the file out.
The last row is the number that matters, because it converts a design complaint into a cost. A tool that saves 20 minutes of drafting and costs 25 minutes of cleanup is not saving anything, and no pricing page will ever tell you that.
Methodology
Every price in this article was read directly from the vendor’s own pricing or help page on 8 August 2026, and each is linked at the point of the claim so you can check it yourself. Figures are USD for the US market. Pitch prices exclude VAT, and Microsoft’s promotional rate covers the first year only.
Where a vendor does not put a figure on a first-party page, we say so and print nothing rather than borrowing a number from an aggregator. All annual totals are our own arithmetic from the published rate, shown so you can redo it.
What we have not done yet: exported the same control deck from all 4 tools into desktop PowerPoint and measured what breaks. So this article makes no first-hand claim about export fidelity. The full protocol is above so you can run it yourself, and we will publish our own results as a dated update.
We recheck pricing here quarterly and after any vendor pricing change we become aware of. Any correction is stated in the text where the error was, rather than folded in silently.
One correction concerns how this article was produced. An earlier version stated Gamma’s help centre slide limit correctly, then a later revision replaced it with the third-party figure and published a correction saying we had misread. That correction was itself the error. Several secondary sources agreeing with one another is not evidence against a primary source, and we treated it as though it were. The figures in the Gamma section come from the vendor page linked there.
This is not legal advice. Check each vendor’s terms, privacy policy and licensing rules before using generated output commercially, particularly around image rights and any confidential material you paste into a prompt.
Reviewed and priced by the Point of AI editorial team. Prices last verified 8 August 2026 against each vendor’s own pricing page. Because these tools change tiers frequently, we recheck this page quarterly and note any change in the text rather than folding it in silently.
Frequently Asked Questions
Can I get an unbranded PPTX from a free plan?
No, not from any of these 4. Budget for a paid tier, and see the tier breakdown above for what each one withholds.
What is the cheapest way to produce one client-ready deck without an annual commitment?
Beautiful.ai sells a single presentation for $45 billed monthly, including everything in Pro. That is more than a month of the annual plan and less than a year of it, which makes it right for a genuine one-off and wrong for anything recurring.
Does Microsoft 365 Copilot include PowerPoint on every plan?
No. Copilot is an add-on requiring a qualifying Microsoft 365 base licence, and the free Copilot Chat tier does not include Copilot inside PowerPoint. Business plans cap at 300 users, above which enterprise licensing applies.
Should I generate the deck in a web tool and finish in PowerPoint, or work natively throughout?
It depends on who edits it after you. If the file goes to someone who will change it, native saves a conversion step and the cleanup that follows one. If you are the only editor and the deliverable is a link, the web tools are faster and cheaper.
How many slides should an AI-generated deck have?
10 to 14 for most business decks, which is roughly where these tools' per-prompt limits sit on entry tiers anyway. If your outline runs past 20, the problem is usually the argument rather than the tool.
