After a week of testing five AI slide generators on a real consulting brief, the tool that produced the best client-ready deliverable was the one that doesn't make slides at all. The brief was market research with financials, charts, macro context, industry landscape, and company facts. Nothing exotic.
It wasn't a close call.
Perplexity, Google Gemini + NotebookLM, Claude for PowerPoint, OpenAI GPT-5.4, Skywork. Five tools, same brief, same brand system, same six-dimension rubric. Each of them is genuinely good at one part of the job and genuinely weak at another. None are client-ready out of the box. The best result of the week came from Claude Artifacts producing an interactive webpage, against a brief we'd normally ship as a PPTX.
I'm writing this for two audiences. If you build decks for a living, whether that's consulting, banking, founder pitches, or market-research shops, you need to know which tool wins which part of the job, because the reality on the ground is that you'll orchestrate several of them. And you need to know when to stop building slides at all.
Let's walk through what actually happened.
The brief
A market-research package is the most common deck a consultant produces. Mine was standard:
- A target company in a specific sector
- Macro environment (5-6 slides)
- Industry landscape (competitive positioning, market size, trends, 8-10 slides)
- Financial performance (multi-year, comparables, unit economics, 6-8 slides)
- Company-specific facts (operations, leadership, strategy, 4-6 slides)
Charts of several types. A comparable-company table. Brand compliance with an existing template. Client-ready editability. The kind of deliverable where, realistically, I'll iterate six versions before anyone outside the team sees it.
I ran the same brief through five tools. Then, on Wednesday, I ran it through a sixth workflow that wasn't even a slide tool.
The six-dimension rubric
To avoid hand-waving, I evaluated each output on:
- Storyline integrity. Does the deck carry one argument from slide 1 to slide N?
- Content depth. Is each slide's substance correct and specific?
- Brand compliance. Does it respect my template, fonts, palette, logo?
- Visual polish. Does it look client-ready, or template-default?
- Editability. Can I open the output and modify any element natively?
- Client-readiness. Could I ship it today without rebuilding?
For each tool, I'll lead with the dimension where it lost to the others. That's what actually matters. Strengths are easy; failures tell you where you still have to do the work.
OpenAI GPT-5.4: loses on brand compliance and polish
GPT-5.4 launched March 5, 2026 with an explicit pitch about "long-horizon deliverables" like slide decks. OpenAI reports human raters preferred GPT-5.4 decks 68% of the time over GPT-5.2. That tracks with what I saw, but only at the storyline layer.
GPT writes the sharpest outline. Action titles that make claims, not topics. Pyramid logic intact. If I ask it to give me the storyboard for a 22-slide market-research deck before any actual slides get written, the arc is almost always good.
Where GPT loses is the moment you ask it to render the deck. Default template. Generic clipart. Fonts that don't match my guidelines no matter how many times I paste the brand spec. Custom instructions and uploaded templates help at the margin; they don't fix it. GPT is a storyboarder pretending to be a designer.
Claude for PowerPoint: loses on storyline cohesion
Claude for PowerPoint released February 5, 2026 and it's the tool built for the consulting use case. It reads your corporate template (slide master, layouts, fonts, colors) and edits in place. Instead of "generate a deck," you ask it to populate your existing deck. The content that comes back is the most detailed I saw from any tool. Real numbers. Fuller speaker notes. No obvious gaps in a financial comparison or an industry-landscape slide.
But Claude is dense at the slide level and less sharp at the arc level. Slide 14 will be substantively correct and disconnected from slide 13. I spent more time re-stitching the story after Claude generated than I did with GPT. It's the inverse problem: Claude is a designer pretending to be a storyboarder.
Perplexity: loses on visual ambition
This was the surprise. I'd used Perplexity as a research engine for a year; I hadn't taken its asset-creation mode seriously. On brand compliance it was the strictest tool I tested. If I gave it a palette, a font pair, and a logo placement rule, it held to the rules more rigorously than Claude or GPT. Every factual claim came back with a citation trace. For market research specifically, that structure is a gift: you can point at a URL instead of at an LLM.
Where Perplexity loses is design. The output looks like a reliable analyst's deck, which may be exactly what you want for market research. It's also exactly what you don't want for a pitch or a management-board slide. Perplexity is a fact-checker pretending to be a designer.
Skywork: loses on editability
Skywork (Kunlun Tech's multi-agent AI workspace) makes the prettiest first-draft deck. Deliberate color systems, cohesive icon design, layouts that don't look algorithmic. Its DeepResearch agent scans 600+ webpages per task, so content quality is also strong.
Where Skywork loses is editability. Many of its visual choices, icons, backgrounds, accent graphics, are baked into the slide as integrated elements, not native editable objects. You end up with slides that look great and resist modification. For a consulting context where the deck will get marked up ten times before anyone external sees it, this is a real problem. Skywork is a designer who refuses to hand over the layered file.
Google (Gemini + NotebookLM): loses on consulting-shape fit
NotebookLM can actually generate slides with the right prompting. That was a surprise. The output is credible for creative or exploratory work, where you're using the deck as a thinking artifact and you're willing to iterate.
Where it loses is the shape of a consulting deliverable. If you show up with a brand asset, a pre-approved template, and a storyline that has to land a specific argument in a specific sequence, NotebookLM's generated slides don't meet you there. You end up doing heavy post-editing to force brand compliance, and heavier editing to fit the dense information a consulting audience expects. By the time you're done, you've rebuilt more than you kept.
Gemini inside Google Slides is the other Google path. It's a slide-by-slide assistant, not a from-scratch generator. It drafts, rewrites, generates images, adds speaker notes. If you already live in Google Slides, it's the path of least resistance. From a zero-to-deliverable standpoint for a consulting deck, it's the weakest of the five tools I tested.
Google's philosophy is "AI inside your existing workflow" rather than "AI replaces the workflow." That's a reasonable stance for creative or knowledge-worker use, less reasonable for consulting where the deck is the work.
What the matrix actually tells you
If I line up the losses, each tool has one specific weak dimension. No dimension has more than one strong tool. Every tool's output, in isolation, requires rework before you could put it in front of a client.
That's why the "which AI slide tool should I use?" question has no answer. Your best option depends on which part of the job you're doing:
- Storyboarding? GPT-5.4.
- Populating a corporate template? Claude for PowerPoint.
- Fact-checking and brand enforcement? Perplexity.
- Visual first-draft for the highest-stakes slide? Skywork.
- Assisting inside an existing Google workflow? Gemini.
The pattern that actually produces a shippable deck is an agent team: GPT writes the storyboard; Claude populates the template; Perplexity verifies facts and enforces brand; a human (or Skywork) polishes the hero slides. It's orchestration, not replacement. The prompt is no longer a single string; it's a pipeline.
The Wednesday pivot
Here is what I didn't plan and didn't see coming until Wednesday.
I ran the same brief through Claude Artifacts, producing an interactive webpage instead of a deck. My expectation was that it'd be a sideshow, something to reference for the few interactive pieces, then back to the PPTX.
It beat every slide tool I'd tested.
Not on slide-like metrics. On the actual job the deliverable was trying to do.
- Brand compliance was tighter. Web fonts, CSS variables, color tokens. 30 years of design-system maturity is already in the stack. The AI didn't have to "try" to respect my brand; the web environment enforced it by default.
- Layout freedom was wider. A slide has roughly 12 archetypes. A webpage has infinite layouts. Charts embedded inline at the right size. Tables that flow. Sidebars for citations. Sections that expand or collapse based on what the reader wants to explore next.
- Storyline was better. I could control scroll pace. Insert a "what this means for you" callout after a data block. Link every claim inline to its source. Embed a small interactive chart where a static bar chart would have been.
- Iteration was faster. Asking Claude to rewrite a paragraph and re-render the page is instant. Asking Claude to rewrite slide 14 and re-render the deck is not.
- The result felt less dated. A modern AI-generated deck still looks like a 2015 deck with 2025 imagery. A modern AI-generated webpage looks like 2026.
This is the shift nobody writing about AI slide tools is acknowledging loudly enough: the best AI for a consulting deck might not be a deck tool. It's a code-generating tool aimed at the same deliverable, using a different format. Claude Artifacts, v0 by Vercel, Lovable, Bolt.new, Replit Agent, and Gamma's site mode are all pushing in the same direction. None of them market themselves as "slide tools." They're producing what the deck is trying to approximate.
Why this happened now
A year ago this wouldn't have worked. Claude Artifacts wasn't mature enough. v0's output looked like framework demos. You couldn't hand a non-technical client a generated webpage without 15 minutes of setup.
Three things changed.
First, the generation quality crossed a threshold. A webpage built by Claude or v0 in 2026 is shippable. The design tokens, layout choices, and interactive components are right more often than not. This is the "generative tools collapse the distance between describe and ship" phenomenon Benedict Evans has written about. The low-cost intermediate artifact we used to call "a deck" is getting replaced by the actual working thing.
Second, sharing got frictionless. A webpage today is a link. The receiving client doesn't need to download a 40MB PPTX, worry about which version they have, or print it badly. Click. Read. Scroll.
Third, and this is the most important shift, the economics of the deck as a mockup fell apart. The deck used to be cheap because it approximated a thing rather than being the thing. Charts were static because live charts were expensive. Stories were paginated because long-scroll design was expensive. That expense gap is gone.
Tome shut down its Slides product in April 2025 and pivoted to AI-for-sales. Tome was arguably the most-hyped AI slide tool of the 2023-2024 cycle. Their pivot is a weak signal but a real one: "generate me a finished deck from a prompt" is a hard product, and maybe a shrinking one.
When slides still win
I'm not predicting the death of PowerPoint. The deck is a specific genre. Dense, annotated, data-laden, designed to survive a board meeting where attention is budgeted in minutes. A well-made deck communicates differently from a webpage, and for some audiences the deck is still the right answer.
Specific cases where the deck still wins in April 2026:
- Email attachments. Every executive opens .pptx in their existing tool; webpages have login ambiguity and privacy-review overhead.
- Offline board meetings. Printed leave-behinds. Legal review. Regulated industries where the document version becomes part of the record.
- Summary-of-quarter narratives for CFOs. A ten-slide quarterly review is a format most executives prefer over a long-scroll page.
- Pitch decks for venture audiences. The genre expectations are specific; investors read 100 decks a week; webpages feel off-convention.
Even for these cases, the agent-team pattern applies: don't lock into one tool; orchestrate the parts. But the output format should be a PPTX.
The practical playbook
If you must ship a deck:
- Storyboard with GPT-5.4 before any slide exists. One-line action titles, full pyramid. Iterate until the story is tight.
- Populate with Claude for PowerPoint against your corporate template. Claude's template-awareness and content depth are load-bearing here.
- Verify with Perplexity. Every factual claim gets a citation pass. Every brand rule gets an enforcement check.
- Polish 2-3 hero slides (title, big-idea, closing) with a human or Skywork. The rest stay in corporate-template plainness, which is what clients actually want.
- Build a custom Claude Skill for your company's layout conventions, font sizes, chart defaults, and brand rules. The prompt is an institutional asset, not a one-off; code it as one.
If you can ship a webpage instead:
- Start with Claude Artifacts or v0. Give the model your brief, your brand tokens, and a structural outline (pyramid structure works here too). Iterate in natural language.
- Embed real data. If the chart can be live, make it live. If the table can be interactive, make it interactive. The format's advantage is that it can be the thing, not approximate the thing.
- Keep a PPT export as a courtesy. Some clients still want it. Generate the PPT from the webpage, not the other way around.
The practical instinct to develop: when you get a deliverable brief, pause before opening PowerPoint. Ask whether the audience and the use case actually need a 4:3 rectangle. Half the time it does. Half the time, increasingly, it doesn't.
The 18-month prediction
By mid-2027, I expect the best-in-class consulting deliverable for a growing share of engagements to be a shareable, interactive web page. Living, embeddable, versioned. With a static PDF or PPTX "export" as a courtesy for the CFO who wants it printed. PowerPoint won't die. It'll move from primary to secondary, the way PDF moved from primary to secondary after Word/Google Docs took over drafting.
If you're on a consulting team, or you're a founder who produces decks every month, or you're an analyst whose monthly report lives in slides: spend one hour this month building a deliverable in Claude Artifacts or v0 instead of PowerPoint. That one hour will change your sense of what's possible.
The AI slide-generation category is trying to automate the artifact most consultants grew up with. The more interesting move, and the one that will actually change what consulting produces, is to question whether that artifact is still the right one at all.
The tools are telling us. The ones that work best for the job don't make slides.
