Plus AI vs Gemini for Google Slides: AI Presentation Builder Comparison (2026)

Introduction

The landscape of presentation software has changed dramatically over the last few years. For a long time, Google Slides was the simple, collaborative alternative to Microsoft PowerPoint. However, the introduction of artificial intelligence has turned the slide editor into a powerful automated workspace. Professionals no longer start with a blank white box. Instead, they start with a prompt.

Two of the most prominent players in this space are Plus AI and Google Gemini. While both tools operate within the Google Slides interface, they take very different approaches to how they help users build decks. Plus AI is a specialized add-in designed specifically for presentation logic and design. Gemini is Google's native AI assistant, built to handle everything from writing emails to generating images across the entire Workspace ecosystem.

Choosing between them is not just about which AI is smarter. It is about which tool fits your specific workflow, how much control you need over your branding, and whether you require deep research capabilities. For a broader look at the market, you can explore our comprehensive review of the best AI presentation builders 2026 to see how these tools stack up against the rest of the industry.

Overview of Plus AI

Plus AI is a dedicated presentation assistant that functions as an add-in for both Google Slides and PowerPoint. Unlike general purpose chatbots, Plus AI was built with a single focus: creating and editing professional presentations. It does not try to be a search engine or a creative writing tool. It is designed to understand the structure of a pitch deck, a quarterly business review, or a training manual.

The tool excels at taking a short prompt or a long document and turning it into a structured set of slides. One of its most significant advantages is its ability to work with your existing templates. Most AI tools force you to use their own designs, which often look generic. Plus AI can "learn" your company's master slides and apply your specific fonts, colors, and layouts to the generated content.

For many users, the most powerful part of Plus AI is not the initial generation, but the "Remix" feature. This allows you to take an existing slide and transform it into a different layout, such as turning a list of bullet points into a three column comparison. This level of granular control makes it a favorite for those who need to maintain high standards of professional design.

Overview of Gemini for Google Slides

Gemini for Google Slides is the native AI integration provided by Google. It is part of the Gemini for Google Workspace suite, which brings Google's most advanced large language models directly into the side panel of your documents and presentations. Because it is built by Google, the integration is seamless. There is no third party add-in to install, and it shares the same credit system and interface as the rest of your Google apps.

Gemini's primary strength is its connection to the Google ecosystem. It can reference files in your Google Drive, pull information from your emails, and use Google's Imagen models to generate custom visuals for your slides. If you are already paying for a Google Workspace business license, Gemini is often the most convenient choice because it requires no extra setup.

However, Gemini is a generalist. While it can generate a ten slide deck quickly, the outputs often feel like a standard Google Slides template with basic text. It lacks the specialized "presentation intelligence" found in dedicated tools. It is excellent for a quick internal draft or a brainstorming session, but it often requires significant manual cleanup for high stakes meetings. If you find the native features lacking, you might want to look into 2026 Gemini Google Slides alternatives to find a more robust solution.

Key Differences Between Plus AI and Gemini

The choice between Plus AI and Gemini usually comes down to three main factors: design control, content source, and workflow depth.

Design and Template Preservation

Plus AI is designed to respect your brand. If you have a custom template that your company has used for years, Plus AI can generate new slides that fit perfectly into that existing deck. Gemini, on the other hand, tends to default to standard Google Slides themes. While you can manually apply your theme later, the AI does not inherently "think" in terms of your specific brand layouts.

Content Sourcing

Gemini has a clear advantage when it comes to internal data. Since it is part of Google Workspace, it can theoretically summarize a document from your Drive or an email thread from your Inbox to create a presentation. Plus AI typically relies on the text you provide in the prompt or a document you upload directly to the add-in.

Editing and Refining

Plus AI offers a suite of "editing" tools that go beyond just creating a deck. You can use it to rewrite specific paragraphs, add a single new slide that matches the current style, or change the layout of a slide without losing your content. Gemini is currently more focused on the "start to finish" generation. It can help you write text or generate an image, but it does not have the same specialized tools for refactoring existing slides.

Pricing Comparison

Pricing is where these two tools diverge significantly. Gemini is often bundled into Google Workspace subscriptions, making it feel "free" for many enterprise users, though it does require a specific Gemini add-on license for full features. Plus AI is a premium third party service with its own subscription tiers.

Plus AI Pricing

Plus AI does not offer a permanent free tier. It is built for professionals who are willing to pay for increased productivity. Plans typically start at $10 per month for individuals. For larger organizations, team plans offer centralized billing and shared templates. This cost is an additional expense on top of your Google Workspace or Microsoft 365 subscription.

Gemini Pricing

Gemini for Google Slides is available as part of the Gemini for Google Workspace add-on. This usually costs around $20 to $30 per user per month, but it covers AI features across Docs, Sheets, Gmail, and Slides. For many businesses, this is the more affordable AI pitch deck builder option because it consolidates multiple AI needs into one Google bill.

The Professional Alternative: NextDocs

While Plus AI and Gemini are the most common choices for Google Slides, they both share a common limitation: they usually give you one result. If the AI misses the mark on the first try, you have to prompt it again and hope for the best. This "trial and error" loop can be frustrating for busy professionals.

This allows you to see different narrative angles, design styles, and content structures side by side. You can then pick the best version or combine elements from several versions into one final product.

Verdict and Recommendation

Choosing between Plus AI and Gemini depends on your specific role and how much you value design precision.

You should choose Plus AI if: You are a power user who spends hours every week in Google Slides.

If you want a tool that can quickly summarize a long email thread into three slides or generate a custom image for a background, Gemini is the most convenient and cost effective option.

You should choose NextDocs if: You want the highest quality output with the least amount of "prompt engineering." If you need real research, multiple versions to choose from, and the ability to export to any format without losing your formatting, NextDocs provides a more robust professional experience than either Plus AI or Gemini.
