Why did the tools perform differently?
The score variations across Gamma, Google Slides with Gemini, SketchBubble, Canva, and SlidesGO stem mainly from differences in product architecture, primary use cases, and integration depth.
1. AI-first vs. template-first design
- Gamma is built as an AI-native presentation generator. It creates complete decks, automatically aligns content and visuals, and supports iterative refinements.
- SlidesGO relies on static, pre-made templates with minimal AI involvement. Users can customize slides after downloading, which limits AI-generated content, multimodality, customization, and iteration capabilities. This results in the lowest overall score.
2. Integrated AI assistant vs. standalone generation
- Google Slides with Gemini adds AI into a traditional slide editor. It performs well in refinement, integrations, and speed, but generates one slide at a time. This constraint lowers its scores in content structuring and overall deck generation.
- Canva follows a design-first model with AI layered on top. It excels in customization, exporting, and brand alignment, but shows inconsistent context and visual consistency because the AI module operates independently of the broader design engine.
3. Template intelligence vs. generative intelligence
- SketchBubble combines structured templates with AI-generated content. It performs reasonably well in terms of context accuracy and visual alignment, but offers limited AI-driven iteration and customization. This positions it mid-tier in total scores.
4. Multimodal and workflow integration differences
- Tools with deeper multimodal pipelines (such as Gamma and Google Slides) handle external files, URLs, and content sources more effectively, thereby improving context and structure.
- Tools without such pipelines (SlidesGO, partially Canva, and SketchBubble) score lower in multimodal input/output and revision capabilities.
Top 5 AI presentation makers
Examples from AI presentation makers
Gamma
Figure 1: An example slide on photosynthesis created with Gamma.
Prompt: “Generate a presentation explaining the basics of photosynthesis for 8th-grade students. Use simple language, diagrams, and examples.”
Gamma received a score of 10 out of 10 for producing a contextually relevant image and providing explanations that aligned well with the prompt.
Google Slides
Figure 2: An example slide on time traveling created with Google Slides.
Prompt: “Create a visually engaging presentation that tells the story of a time traveler exploring ancient civilizations. Include 5 key historical stops, fun facts, and interactive elements.”
Google Slides received a score of 9 out of 10. While the tool demonstrated strong visuals, adequate writing, and a clear understanding of the prompt, the final output was somewhat plain and limited to a single slide, rather than producing multiple slides as requested.
SketchBubble
Figure 3: An example slide on “how to start a podcast” created with SketchBubble.
Prompt: “Build a presentation titled: How to Start a Podcast in 2025. Include equipment needed, planning tips, recording tools, publishing platforms, and growth strategies.”
SketchBubble received a score of 6 out of 10. The slide performs well in terms of clarity, visual integration, and accessibility. However, it could be improved by enhancing visual AI integration, expanding contextual understanding, and offering increased design customization options.
Canva
Figure 4: An example slide on photosynthesis created with Canva.
Prompt: “Generate a presentation explaining the basics of photosynthesis for 8th-grade students. Use simple language, diagrams, and examples.”
This presentation received a score of 6 out of 10. One issue noted was its inability to generate contextually appropriate images, for example, displaying a car tire to represent oxygen production and using a picture of a person to depict a food source.
SlidesGo
Figure 5: An example slide about an investor pitch created with SlidesGo.
Prompt: “Create a 10-slide investor pitch deck for a new eco-friendly water bottle startup. Include market analysis, product features, business model, and financial projections.”
SlidesGo received a score of 4 out of 10. There are multiple problems with the SlidesGo slide. The letters and numbers in the image on the right are unreadable, undermining the quality and integrity of the visuals.
Also, the slide claims to present a break-even analysis, but the visuals show generic dashboard charts rather than an actual break-even chart, creating a mismatch between the message and the visuals.
What is an AI presentation maker?
Instead of designing slides from scratch, users can type a prompt or topic, and the AI generates a presentation, including content, layout, and design assets such as images, colors, and fonts.
These tools are ideal for students, professionals, and product teams who want to focus more on ideas and messaging than on slide formatting. With an AI slide maker, users can access presentation templates and customizable templates that save time and help them deliver visually appealing presentations.
Key features of an AI presentation maker
- Presentation templates and styles: Offers ready-to-use templates and additional designs that fit different needs, like a pitch deck, class project, or company update.
- Customizable design tools: Use built-in design tools and an online editor to customize fonts, color schemes, and text boxes to match the brand kit or personal style.
- Own images and AI image generator: Users can upload their own images, logos, or brand assets, or use the integrated AI image generator to create unique visuals.
- Interactive and engaging slides: Add interactive slides, videos, and graphics to engage the intended audience.
- Easy export and integration: Download as a PowerPoint file or use the built-in PowerPoint generator. Some tools also integrate with Google Slides and other apps to help users start presenting instantly.
- Free plan and accessibility: Many AI tools offer a free version so users can try before upgrading. This is ideal for quick, on-the-go creations with lifelike results.
