AI presentation tools compared: a designer’s independent view

Last checked: 21 September 2026. Features and prices in this space change monthly. The dated details below will age; the categories they sit in won’t.

Almost every comparison of AI presentation tools is written by one of the tools. That’s not a criticism, it’s just the market: the vendors have the content budgets. So here’s a view from the other side of the process. I’m a presentation designer, and a growing share of my work is fixing what these tools produce. I’ve read each vendor’s own documentation, their pricing, and the most recent credible reviews, and set it against what actually lands on my desk.

I’m not going to crown a winner. The right tool depends on where your organisation already works. What I will do is sort them by the one question that matters most for serious work, and it isn’t which one makes the prettiest first draft.

The question that sorts them: does it respect your template?

A tool that generates a nice-looking deck in its own style is solving a different problem from yours. If you’re a business with a brand, you don’t need a deck that looks good. You need one that looks like you. So the useful dividing line is this: does the tool work inside your real template, or does it bring its own?

That splits the field neatly in two.

Tools that live inside your existing software

These work inside PowerPoint or Google Slides, in your file, on your template. For most organisations, this is where to look first.

Copilot in PowerPoint. Microsoft’s own. The big news this month (14 September) is a Brand Kit with a “strict brand adherence” setting that locks Copilot to your approved layouts, plus per-layout instructions. That’s a serious step toward the thing businesses actually need. It’s an add-on to Microsoft 365, around £30 per user per month in the UK at list (resellers vary). Reviewers still report vague error messages and a prompt length limit. Best fit: organisations already on Microsoft 365 with a properly built template.

ChatGPT for PowerPoint. A PowerPoint add-in that builds, edits and rewrites inside the open file, and can pull context from your email and documents. OpenAI’s GPT-6, announced 3 September, is pitched explicitly as its best model yet for adhering to existing templates. Bundled into ChatGPT plans (Plus is $20 a month). Honest reviews describe the output as visually plain, first-draft quality, and both OpenAI and Microsoft flag complex templates, charts and animation as needing human review. Best fit: teams already living in ChatGPT who want drafting speed.

Claude in PowerPoint. Anthropic’s add-in reads your slide master, layouts, fonts and colours before it generates, so output lands in your template rather than beside it. It’s included with paid Claude plans. One reviewer couldn’t get it to edit the master itself, and some chart types (waterfall, Gantt) aren’t supported. Anthropic also launched Claude Slides on 16 September, a separate chat-native deck builder, still in beta. Best fit: people who want strong structure and writing inside their existing file.

Gemini in Google Slides. Built into paid Google Workspace. It can take an existing deck as a style reference so new slides match it. Reviewers call that a useful bridge rather than true template enforcement, and that’s fair: matching a style is not the same as obeying a layout system. Best fit: Workspace organisations, especially for internal decks.

Plus AI. An add-on for both Google Slides and PowerPoint that works in the open file. Using your company’s own template is an Enterprise-tier feature. Reviewers find the PowerPoint side slower than the Slides side. Best fit: teams split across both tools who need one assistant.

Standalone tools with their own editor

These generate decks in their own app, in their own house style, and export to PowerPoint afterwards. They can be fast and polished. They are also, by design, not working in your template.

Gamma. The best known of the standalone makers. Genuinely quick, with a recognisable look. There’s no import of a PowerPoint master; instead a plan-gated Brand Kit handles logo and colours. Exported PowerPoint files can shift layouts and substitute fonts, and reviewers report spending fifteen to forty-five minutes fixing exports on anything non-trivial. From free (watermarked) to $18 a seat on Pro.

Presentations.AI. Generates from a prompt, outline, document or URL. Template support means its own library, or a saved custom master on the top tier. Reviewers note repetitive output across design options. The interesting detail is further down the page, which I’ll come back to.

Beautiful.ai. Smart templates that re-layout automatically as you add content, which genuinely helps non-designers. Team brand kits lock colours and fonts, but reviewers say they fall short of enforcing layout structure. Exports mostly open cleanly. No free plan, a 14-day trial, from $12 a month.

Pitch. A collaborative deck workspace with an AI agent that builds from your team’s saved templates. Strong for real-time teamwork. Reviewers flag weak governance for corporate use: no deleted-files folder and no granular permissions. Free for small teams.

Decktopus. A budget generator. No PowerPoint template import, only a colour-and-logo brand kit. Reviewers report exported PowerPoint files arriving as flattened images, and the pricing is inconsistent even across the vendor’s own pages. I’d approach with caution.

What every one of them still gets wrong

Here’s the part the feature lists don’t cover. Across all ten, the same things come back to me for fixing, and none of the recent updates change them.

They format; they don’t design. Every slide gets equal weight because the tool doesn’t know which number the room came for. They follow templates literally, not intelligently, so a brand-compliant slide can still hold three slides’ worth of content. They shed detail on the way in: footnotes, sources, the last bullet. And they all have a look, which audiences are starting to recognise. I’ve written about those tells in more detail.

The quiet admission in the market

Remember Presentations.AI? It sells a human design studio alongside the software. An overnight redesign of an existing deck starts at $999. Custom template development runs from $6,000 to $25,000.

That’s an AI company telling you, in its own price list, where its tool stops and a designer starts. It isn’t a criticism of them. It’s the most honest thing anyone in this market has published.

How I’d choose

Start with where you already work. Microsoft 365 organisation: Copilot, or Claude or ChatGPT inside PowerPoint. Workspace organisation: Gemini. Split across both: Plus AI. Standalone makers suit individuals and startups without a brand system to protect.

Then fix the template, because it now matters more than the tool. Every serious tool on this list is moving toward generating into your template. Copilot will now lock itself to it. So your template stops being a starting point and becomes the policy every generated deck follows. If it’s badly built, the tools will reproduce its flaws faster than any person could. Here’s what makes a template AI-ready.

Then decide which decks are worth a designer. Use the tools for drafts, internal updates and speed. For the pitch, the board and the client who judges in ten seconds, the tool gets you to a first draft. It doesn’t get you to the room. That’s the gap I work in, and why the arrival of GPT-6 makes it wider, not narrower.
