Slides AI and Gamma AI are two popular tools designed to take the pain out of building presentations — but which one is actually worth using?
I’ve spent the last few weeks testing both platforms side-by-side, comparing their AI output, ease of use, design quality, pricing, and more. If you’re trying to decide between these two, this breakdown will save you hours.
Gamma AI is the better option if you want sleek, web-based presentations with zero design effort.
Slides AI is best if you need editable PowerPoint or Google Slides and want control over every detail.
Let’s break it down so you can choose what works best for you.
Slides AI vs Gamma AI: Quick Verdict

Here’s a side-by-side comparison of both tools so you can quickly see what each one offers:
| Feature | Slides AI | Gamma AI |

Best for AI Slide Generation: Gamma AI
Both tools offer AI-generated slides, but Gamma AI’s results are noticeably better.
Gamma AI
- Gives you a full slide deck based on your prompt, and it looks great immediately.
- Suggests layouts, adds relevant visuals, and maintains consistency.
- Built-in themes and formatting tools make the final deck ready to present.
When I asked Gamma to create a deck about “content marketing strategies for 2025,” it delivered an 8-slide presentation with visually engaging layouts, icons, and example case studies. I didn’t have to touch a thing.
What really stands out is how Gamma understands the context of your content. It doesn’t just split paragraphs into bullet points — it interprets structure, tone, and narrative flow.
If your input has a beginning, middle, and end, Gamma reflects that in how it builds the story visually. It feels more like a creative assistant than a basic AI tool.
Slides AI
- Feels more like a content generator than a designer.
- Delivers slides with title + bullet format, but minimal visual styling.
- Works directly inside Google Slides, which is convenient — but the output is plain.
Slides AI is helpful if you just want structure, and don’t mind doing all the formatting yourself.
The AI works best when fed structured content like outlines or bullet points. If you give it a block of raw text, it tends to generate repetitive or overly simplistic slides.
It’s not built to guide the narrative — it’s designed to quickly drop content into a slide deck format you’re already used to.
The Winner
Gamma AI wins on AI output quality. Its results are more polished and presentation-ready, which means less editing for you.
Best for Design and Visual Appeal: Gamma AI
This was a clear win for Gamma.
| Criteria | Slides AI | Gamma AI |
|---|---|---|
| Visual Themes | Limited | Dozens of modern templates |
| Typography | Basic (from Google Slides) | Built-in fonts, easy to customize |
| Image Handling | Manual | AI inserts relevant visuals |
| Layout Choices | Text-heavy | Balanced, visual-first layouts |
Gamma is designed for modern audiences — investors, clients, teams — where presentation aesthetics matter.
Slides AI sticks to traditional formatting. That works for class reports or internal decks, but not if you want to impress visually.
Gamma also adds subtle design elements that make a difference — things like white space, iconography, modern font pairings, and soft transitions.
These aren’t huge features, but they stack up. The end result feels cleaner, more professional, and more engaging — especially when presenting to clients or pitching a product.
The Winner
Gamma AI wins for design. It’s cleaner, faster, and looks more professional without effort.
Best for Flexibility and File Output: Slides AI
While Gamma excels in modern design, it falls short in flexibility and file exports.
Slides AI
- Exports to PowerPoint and Google Slides.
- You can open and edit every slide element.
- Fully offline-compatible once exported.
This makes Slides AI a strong option if you’re working in environments where file compatibility is a must — like enterprise settings or government organizations.
You can generate a rough draft with AI, then hand it off to your team for polishing without needing to learn a new platform.
Gamma AI
- Web-based only.
- You can export to PDF — but not PPT.
- Limited ability to tweak design elements post-generation.
- Ideal for sharing links or presenting live from your browser.
That said, Gamma’s export limitations can be frustrating if you’re expected to deliver a .PPTX or integrate into existing slide decks.
While it’s great for presenting online, Gamma still doesn’t offer a straightforward way to bring its content into traditional presentation workflows — which can be a dealbreaker in some settings.
The Winner
Slides AI wins on flexibility. You can generate your slides with AI and still have full editing power.
Best for Collaboration and Sharing: Gamma AI
Modern teams don’t just make slides — they review, comment, and collaborate.
Gamma AI
- Real-time collaboration
- Commenting built-in
- Easy to share via a simple link (no attachments needed)
- Designed for async work and distributed teams
Gamma’s structure is especially helpful when you’re working across time zones. You can drop in comments, assign edits, and track changes directly in the browser.
There’s no need to juggle email chains, file versions, or permissions. It’s a real bonus if you’re part of a fast-moving marketing or product team.
Slides AI
- Relies on Google Slides’ sharing tools
- No native collaboration features
- Still effective, but nothing new
If you work solo, this might not matter. But for marketing, sales, or design teams — Gamma makes collaboration easier.
The Winner
Gamma AI wins for collaboration. It’s clearly built with teams in mind.
Best for Pricing: It’s a Tie
Both tools are affordable, but pricing structure and what you get varies slightly.
Slides AI Pricing
- Free Plan: Limited generations
- Starter: $10/month
- Pro: $20/month (includes premium templates and formatting)
- Enterprise: Custom pricing
Gamma AI Pricing
- Free Plan: Watermarked presentations
- Starter: $8/month
- Pro: $25/month (includes custom branding, analytics)
- Enterprise: Custom pricing
| Plan Tier | Slides AI | Gamma AI |
|---|---|---|
| Free | Yes | Yes |
| Starter | $10/month | $8/month |
| Pro | $20/month | $25/month |
| Exports PPT | Yes | No |
| Branding | Google Slides | Custom branding |
| Analytics | No | Yes (Pro only) |
Both tools are trying to offer great value for small teams and individuals.
Gamma is slightly cheaper to start, but Slides AI gives more export flexibility in its lower tiers.
So which one is “cheaper” really depends on how you’re planning to use it — whether you value design or editable file types more.
The Winner
It’s a tie.
Choose Slides AI for traditional decks and full editing.
Choose Gamma AI for visual polish, even if it costs a bit more.
Best for Presenting and User Experience: Gamma AI
If you want to present live or share online decks, Gamma is ahead.
Gamma AI
- Built-in presentation mode
- Responsive on mobile and tablet
- Lightweight, fast-loading decks
- Share a single URL — no download needed
Presenting with Gamma is frictionless. You don’t need to download files, worry about compatibility, or set up screen-sharing tools.
The link you share becomes the presentation — and it looks the same on any device. That’s especially useful for sales teams or startups who pitch regularly to different audiences.
Slides AI
- You present in Google Slides or PowerPoint
- Not optimized for mobile viewing
- Familiar format, but not optimized for performance
The traditional approach still works well for in-person meetings or formal settings, but you’ll need to double-check formatting and device compatibility before going live.
It’s reliable, but not optimized for remote or mobile-first delivery.
The Winner
Gamma AI is better for modern presentation delivery. It’s smoother and simpler to share and present from anywhere.
Real User Feedback
I checked Reddit, Product Hunt, G2, and other forums to get honest takes from real users.
What People Say About Slides AI
Pros:
- “Great for school or quick internal decks”
- “Simple interface — no learning curve”
- “Love that it works directly in Google Slides”
Cons:
- “Designs are very plain”
- “I always have to redo the visuals”
- “Feels like a rough draft tool”
Beyond forums, I also found Slides AI mentioned in a few educational blogs where teachers recommended it for quickly turning lesson plans into basic visual aids.
It’s clearly popular among students and educators — not because it’s flashy, but because it’s fast and practical for people who already know how to edit slides manually.
What People Say About Gamma AI
Pros:
- “Decks look beautiful out of the box”
- “Perfect for startup demos and investor decks”
- “Feels like Notion but for presentations”
Cons:
- “Wish it exported to PowerPoint”
- “Takes time to adjust to the interface”
- “Some clients still want ‘traditional’ slides”
Gamma users on Product Hunt often mention how the platform “makes them look good” without needing to spend time tweaking slide layouts or hunting for icons.
Several solo founders mentioned they switched from Canva or Pitch because Gamma delivered faster results with more polish.
Final Recommendation
Here’s my bottom-line recommendation based on testing both tools:
Choose Gamma AI if:
- You want clean, polished decks without needing to edit
- You share presentations via link or present live online
- You’re in a creative, marketing, or startup environment
Choose Slides AI if:
- You use Google Slides or PowerPoint
- You want to keep your decks offline or editable
- You need a fast draft builder, not a design tool
For most modern use cases, Gamma AI is the more advanced solution.
But if you’re stuck in a traditional workflow (or working with clients who are), Slides AI is the safer choice.
If you’re unsure, try both tools on their free plans before committing to a paid plan.
Spend 30 minutes creating the same deck in each tool — that’s usually enough to tell which one fits better with your workflow, design preferences, and how you share slides.
In the end, the best tool is the one you’ll actually use consistently.
