AI add-ins for PowerPoint: 9 compared

Every tool here works inside PowerPoint rather than exporting a deck to it. What each one does on the slide, what it costs, and the distinction that decides which you need: generating a deck versus updating one.

There are two completely different products in this category and the roundups keep listing them together. One makes a deck that did not exist: you type a topic, it writes slides. The other works on a deck that already exists and has to be produced again next month in the same template. The first is crowded and cheap; the second is nearly empty. Which one you need is not a matter of taste — it depends entirely on whether your deck recurs.

Sister directories: AI add-ins for Word, Google Slides add-ons, Google Docs add-ons and AI add-ins for Excel. For the mechanics without any add-in, see how to make a chart in PowerPoint and how to insert an Excel chart into PowerPoint.

Fair warning: Quiriz is ours, and it is in this list. I have said plainly where the others beat us — for building a deck from scratch, several of them are the better buy and it is not close. Capability claims come from each vendor's own AppSource listing or documentation, checked September 2026. Pricing moves constantly in this category; confirm before you buy rather than trusting any roundup, including this one.

The distinction that matters: generating a deck vs updating one

Ask one question before you look at any product page: does this deck exist already, and will it exist again next month?

• New deck, one time. A pitch, a workshop, a conference talk. You want slides out of nothing, and design quality is the whole value. Plus AI, SlidesAI and Copilot are all good at this, and so are the web generators that export a .pptx.
• Existing deck, recurring. A monthly business review, a pipeline review, a client report. The slides are settled and the work is new numbers in the same shapes, in your template, without anything being left on last month's figure. Almost nothing in this category does that job, and the tools that are excellent at the first job are no help at all with it.

A third group is narrower and older than the AI wave: charting and timeline tools that draw a specific kind of graphic far better than PowerPoint can. They are not AI and they are frequently the right purchase anyway.

Quick comparison table

"Updates next month" means the add-in can bring an existing slide current against new data without the slide being rebuilt — not that it can regenerate a deck from a fresh prompt.

Microsoft 365 Copilot

The job: draft a deck, rewrite slides, summarise a long presentation, and reach your other Microsoft 365 content.

Copilot is in the ribbon rather than in a bolted-on pane, and it is the only option here that can reference your own files, meetings and email through Microsoft Graph. "Make a deck from that project document" is a real Copilot instruction and not a real anything-else instruction. It also works the other way, summarising a deck someone sent you.

Where it stops: a per-user licence on top of a per-user licence, which is a heavy default for a team where three people build the decks. On data it is better than the generators and still not a reporting tool: it can find the spreadsheet and quote it, but it does not compute a metric across your datasets, chart it, and let you refresh both next quarter.

Pick it if your organisation is already all-in on Microsoft 365 and you want one AI across PowerPoint, Word, Excel and Outlook.

Plus AI

The job: generate a deck, generate a single slide, rewrite a slide, or reformat an existing slide into a different layout.

The strongest third-party generator that behaves like an add-in rather than an export tool, and consistently the one professional deck-builders name. Generating a whole presentation is the headline, but the useful daily features are smaller: rewriting one slide, or taking a slide you already have and reformatting it into a cleaner layout without redoing it by hand.

Where it stops: it writes the words, not the numbers. Everything it puts on a slide came from the prompt or the model, so a figure on a generated slide is only as true as whatever you pasted into the prompt.

Pick it if you build a lot of new decks and want a good one faster.

SlidesAI

The job: paste text, choose a theme, get slides.

The lowest-friction text-to-deck tool, and it works the same way in PowerPoint and Google Slides — which matters if your organisation straddles both. Paste notes or a document, set a slide count, pick a theme, and a complete deck appears. Quality is solid for standard business and teaching content.

Where it stops: theme-driven rather than template-driven. If your company deck has a strict master, expect to restyle. And as with every generator, it writes prose, not analysis.

Pick it if you have the content written and want it turned into slides with minimal fuss.

Claude for PowerPoint

The job: a strong writing and restructuring assistant that can read the whole deck.

Anthropic ships first-party add-ins for PowerPoint, Word, Excel and Outlook. The PowerPoint pane can read the open presentation, which makes it good at the things that need the whole argument in view: tightening a rambling deck, finding the slide that contradicts slide four, rewriting a section in a consistent voice.

Where it stops: it works with the deck, not with your systems, and it needs a paid Claude plan. It will discuss the numbers on your slides without any way of knowing whether they are right.

Pick it if the deck is mostly argument and the hard part is the thinking.

Quiriz for PowerPoint

The job: build the recurring deck from your own data, and bring it current before the next meeting.

Ours, so read it accordingly. This is squarely the second category above. You pick the data, say what the deck is for, and Quiriz shows you the plan before it builds anything: each slide's title, the question it will ask, and whether it will show a chart, a table or text. Edit the titles, untick what you do not want, add a slide of your own, then press Build. Each slide lands in your template's own layout with its chart in the deck's theme colours and two to four takeaways beside it written from that chart's own figures.

Smaller gestures do the day-to-day work. Type a question and press New slide for one slide, or Add to put the answer on the current one. Write =QUIRIZ.ASK("net sales by month") into your template — with "table", "both", "figure" or "notes" as an optional second argument — and press Build from markers, so your layout decides where each answer sits. Highlight a question inside a text box and press Figure to replace just those words with one live value, leaving your font and layout untouched. Press Change on a chart and say what you want in words; the style travels with the chart through every later refresh.

Then Refresh all: every chart, table, figure and note keeps its question on the shape, so one press asks them all again and redraws each object where you left it. Totals, charts and takeaways move together from the same data.

Where it stops, honestly: it will not write you a pitch deck. There is no design-from-a-prompt, no "make this beautiful", no stock imagery — for a new deck that has to look good, Plus AI or SlidesAI is the right purchase and we are not competing for it. It needs your data in Quiriz first, which is real setup that only pays back if the deck recurs. And the host matters: PowerPoint 2021 and later on Windows and Mac plus PowerPoint on the web, with real PowerPoint tables needing Microsoft 365 version 2504 or later or the web, and on perpetual 2021 and 2024 a new slide is added at the end of the deck rather than after the current one.

Pick it if you present the same deck every month and the tedious half is the numbers.

think-cell

The job: charts that PowerPoint genuinely cannot draw.

Not AI, and for a certain kind of work the most valuable thing on this page. Waterfalls, Mekko charts, stacked columns with correct difference arrows, CAGR annotations, automatic label placement that does not collide — the chart vocabulary of management consulting, drawn properly and linked back to Excel so the numbers can be updated. Anyone who has tried to fake a waterfall with invisible series knows exactly what this saves.

Where it stops: it is a paid desktop product, it does not analyse anything, and you supply the data. It draws.

Pick it if your decks contain real financial charts and you have been building them by hand.

Office Timeline

The job: timelines, roadmaps and Gantt slides that look designed.

A specialist that keeps showing up because the alternative is drawing rectangles by hand. It imports from Excel, Project and Smartsheet, and produces a native PowerPoint graphic you can edit as shapes. There is a free edition with fewer styles and a paid one.

Where it stops: one shape of problem, done well. Nothing else.

Pick it if a roadmap slide appears in your decks more than twice a year.

AI Perfect Assistant

The job: a library of ready-made prompts spanning PowerPoint, Word, Excel and Outlook.

Prepared actions rather than a chat box — rewrite this, summarise, generate slide text, expand these bullets — across the whole suite from one purchase. For people who know what they want done and do not want to phrase the instruction each time.

Where it stops: breadth over depth, and the same data blindness as every generator here.

ClassPoint, Mentimeter and the engagement add-ins

A different category worth knowing exists: add-ins that turn a presented deck into something the room answers back to. Live polls, quizzes, word clouds, annotation over the slide, gamified activities. ClassPoint and Mentimeter are the common names; there are many more, and teaching is where most of them earn their keep.

Nothing to do with AI or with data, and if your problem is that nobody engages with your deck, more relevant than anything above it.

How to install an add-in in PowerPoint

1. Open PowerPoint and go to the Home tab. Click Add-ins. On some versions it is Insert → Get Add-ins.
2. Search AppSource by name and click Add.
3. The add-in appears as a ribbon button and opens a task pane beside the slide.

Two caveats. On a work computer the store may be switched off, in which case add-ins are deployed centrally through the Microsoft 365 admin centre and nothing you click in PowerPoint will change that. And older desktop products — think-cell among them — install as traditional programs rather than through AppSource, so they live on one machine rather than following your account to the web.

Which should you pick?

• New decks, often, and they must look good. Plus AI, or SlidesAI if you want the simplest possible path.
• Already deep in Microsoft 365. Copilot, if the per-user cost clears for the people who actually build decks.
• The deck is an argument and needs tightening. Claude for PowerPoint.
• Waterfalls, Mekkos and real financial charts. think-cell. Nothing else is close.
• Roadmap and timeline slides. Office Timeline.
• The room should answer back. ClassPoint or Mentimeter.
• The same review deck every month, with new numbers. Quiriz for PowerPoint — a different purchase from the generators, not a competing one. Running a generator for new decks and a reporting add-in for the recurring one is a perfectly sensible pair.

The one mistake worth avoiding: buying a deck generator to solve a monthly reporting problem. It will produce a beautiful new deck every month, in a slightly different shape each time, with numbers you typed into the prompt yourself — which is the work you were trying to stop doing.
