How to Use Plus AI for Google Slides: A Practical Walkthrough

Why Plus AI for Google Slides, and What to Expect

If you spend your day in Google Slides, the last thing you want is to draft a deck in some external AI tool, export it, and spend an hour reformatting it. Plus AI's core pitch is that you never leave: it installs as an add-in inside Google Slides (and PowerPoint), and one reviewer described the experience as feeling "like a natural feature of the presentation environment" rather than a bolted-on tool.

It's worth understanding what kind of tool Plus AI actually is before installing anything. It sits in the add-in category, competing not with standalone design platforms but with generalist assistants like Gemini. A detailed comparison describes Plus AI as built specifically for presentation logic and design, while Gemini works across Google Workspace and leans on your Drive and Gmail data. The trade-off: Gemini defaults to standard Slides themes, while Plus AI works within your existing master slides, fonts, and colors so new slides don't need hours of manual reformatting.

Now the honest part — three caveats you should know upfront:

• There's no permanent free tier. You get a 7-day trial with 1,000 AI credits, then paid plans start at $10/user/month billed annually ($15 monthly), with tasks typically consuming 40–170 credits each.
• Generation is slow. In a hands-on test across 12 AI presentation tools, Plus AI took roughly 2 minutes to generate a 10-slide deck — described as one of the slowest tools tested, where some competitors finished in under a minute.
• Output depends heavily on your prompt. The same comparison notes the tool is "highly dependent on the quality of the initial prompt," and the hands-on test rated content quality as merely "OK-ish," with a basic outline and no research step.

Pricing sits in familiar territory for this category. Annual plans run $10–30 per user per month (Basic, Pro, and Team tiers), with a Max plan at $200/month for unlimited credits. That's comparable to Gemini for Workspace at roughly $20–30 per user per month, and slightly above MagicSlides, which offers a free tier with paid plans from around $8/month. One Plus AI subscription covers both Google Slides and PowerPoint natively, which matters if your clients or colleagues are split between the two.

So who should consider it? The hands-on reviewer's verdict is a good rule of thumb: use Plus AI if you're already comfortable with Google Slides or PowerPoint and want AI assistance without learning a new platform. If you want raw design power or a free tier, standalone tools will likely serve you better.

It's also worth noting where Plus AI is heading. It has expanded beyond prompt-to-deck generation into a "Presentation Agent" with API and MCP-oriented workflows, enabling free-form presentation work rather than a fixed wizard. That direction — agents handling presentation tasks end to end — is exactly the space SkillzBench is building for, with independent benchmarks, security scans, and a free MCP connector to help you verify which agent skills actually deliver before you rely on them.

The Core Walkthrough: Install to Generated Deck

The whole appeal of Plus AI is that you never leave Google Slides — the AI shows up as a sidebar inside the tool you already use, rather than forcing you onto a separate design platform. Here's the concrete flow, based on hands-on testing by StoryChief, from a blank browser tab to a finished first draft.

Step 1: Install the extension. You install Plus AI through the Google Workspace extensions panel, granting it permissions to work inside your Slides and Docs. There's no permanent free tier — every plan starts with a 7-day trial that includes 1,000 AI credits, per Plus AI's pricing details.

Step 2: Open the extensions panel in Google Slides. Once installed, Plus AI appears as a sidebar — one reviewer described the learning curve as "low," thanks to an intuitive sidebar interface rather than a new app to learn.

Step 3: Enter a prompt. StoryChief's test used a simple prompt — "Create a 10-slide presentation on the benefits of content marketing" — and the output quality was, in their words, "OK-ish." Keep in mind that results are highly dependent on prompt quality; detailed prompts get noticeably better decks.

Step 4: Review the outline. Plus AI generates an outline before building slides. StoryChief called this outline "a bit basic," and importantly, there's no built-in research step — the tool works from your prompt and uploads, not from live web research. Treat the outline as your quality gate: edit it here, before a single slide renders.

Step 5: Generate the deck. In StoryChief's test, a 10-slide deck took roughly two minutes — respectable, though they ranked it among the slower tools they tried. Once generated, the real work begins, and this is where Plus AI's post-generation toolset earns its keep:

• Rewrite — regenerate or refine text on existing slides without starting over.
• Single-slide insertion — add one slide in a specific layout, which Plus AI pitches as "more control than generating an entire presentation."
• Remix — transform a layout, e.g., turning a dense paragraph into a three-column comparison, while preserving the content itself.

That Remix capability — restructuring without rewriting — is what separates a genuine editing tool from a one-shot generator. If you want to push the rest of that workflow (research pulls, data gathering, follow-up decks) to an AI agent, SkillzBench's free skills directory and the MCP connector it's building are a good place to see what's possible — and what's been security-scanned before you trust it.

Validate Before You Commit: A Branded-Deck Testing Protocol

A demo deck tells you almost nothing. Vendors generate polished samples under ideal conditions — your acceptance test should be whether Plus AI can handle your templates, your revision cycles, and your delivered files. As one reviewer put it, "'Works in PowerPoint' is a starting point; professional editability is the acceptance test" source.

Start with the quick screen. AnyGen recommends a simple validation flow before committing: open the result in the app your team actually uses, then move 3 slides, edit 2 text boxes, and apply 1 existing layout source. If basic manipulation breaks formatting or forces you into awkward workarounds, you'll feel that pain daily — better to find out in five minutes than after a team rollout. AnyGen also cautions that "a custom template is not the same as a branded first slide," so validate your title, section, data, quote, and closing layouts specifically source.

Then go deeper with a 30-minute branded-deck protocol adapted from Deckary's review. The author, a former McKinsey and Deloitte consultant, argues the real question "is not whether Plus AI can generate slides; it is how well it handles your existing templates, revision cycles, sources, and final artifact" source. His trial sequence:

• Import a real ten-slide branded deck — not a demo file.
• Ask for a storyline summary and one evidence gap in the narrative.
• Add a new source-backed slide and check it matches your layouts.
• Update one chart while preserving native editability — no flattened images.
• Reopen the delivered file and time how long manual cleanup takes.

That last step matters most. The whole appeal of an in-app add-in is that generated slides match your master slides, fonts, and colors without "hours of manual reformatting" source. If your cleanup timer says otherwise, template fidelity is failing in practice even if it works in marketing screenshots.

Two principles should anchor your evaluation. First, template fidelity beats generation flash — a tool that produces dazzling slides in the wrong theme saves you nothing. Second, test recovery, not just happy paths: Deckary suggests buyers check whether the agent "can continue through complex edits and recover from an imperfect step" source. Real work involves mistakes; your tool should absorb them.

This verify-before-you-trust mindset applies beyond slide tools. SkillzBench is building exactly this discipline for agent skills — sandbox benchmarking, security scanning, and version-pinned verification — so you can see which skills actually lift performance before they touch your workflow. Browse and test free agent skills on SkillzBench, and apply the same protocol: real inputs, real edits, timed cleanup.

Pricing, Plans, and the Trade-Offs Worth Knowing

Before you commit to any AI slide tool, the price tag only makes sense once you understand what each tier actually unlocks — and where the credit system will bite.

Plus AI's pricing ladder runs from Basic at $10/user/month billed annually (or $15 monthly) up to Max at $200/$240, according to its official pricing page. In between sit Pro at $20/$25 and Team at $30/$40. Every plan starts with a 7-day trial carrying 1,000 AI credits — there is no permanent free tier.

The tiers map cleanly to features. Here's what changes as you climb:

• Basic ($10/$15): 1,500 credits per month, enough for light, occasional deck generation.
• Pro ($20/$25): 3,000 credits, plus file-to-deck conversion — upload PDF, DOCX, PPTX, or text files to build slides from existing documents.
• Team ($30/$40): 6,000 credits, custom templates (beta, Google Slides-only, 25-slide max), saved brand colors, fonts, logo uploads, and custom instructions.
• Max ($200/$240): unlimited credits for heavy, organization-wide use.

Credits are the real budgeting variable. Tasks typically consume between 40 and 170 credits depending on complexity, so a Basic plan's 1,500 monthly credits translate to roughly 9–37 generation or editing tasks — thin margin if your team iterates heavily.

How does that stack against alternatives? Gemini for Google Workspace runs approximately $20–$30 per user per month but spans the whole suite rather than specializing in slides. MagicSlides offers a free tier with paid plans from around $8/month, and SlidesAI lands at $10–20 per user/month on annual billing. If you mainly need quick drafts from a URL or YouTube source, the cheaper tools may suffice; if template fidelity and in-place editing matter, Plus AI's premium is buying that workflow.

Two caveats worth weighing. Pricing varies by source and date — some reviews list only the monthly figures ($15–$40) — so verify current rates before deciding. And note that Plus AI has expanded toward a Presentation Agent with API and MCP-oriented workflows, which hints at where this category is heading: agents that handle the full presentation pipeline, not just slide generation.

That's also where agent skills come in. Research, data pulls, and follow-up deck variants can all be automated by agent skills outside the slide tool itself. SkillzBench is building a free directory of independently benchmarked agent skills plus a free MCP connector, so you can test which ones genuinely help before wiring them into your workflow.

Bottom line: match the tier to your iteration volume, trial the credit math with a real deck, and treat the annual billing discount (~33% off monthly rates) as the default choice for any committed team.

Beyond the Wizard: Plus AI's Agent Direction and Where Skills Fit

Plus AI started as a prompt-to-deck wizard, but it's evolving into something more interesting: a "Presentation Agent" with API and MCP-oriented workflows, a shift documented in a recent in-depth review. That move matters because it reframes the tool from a one-shot generator into part of a broader agent stack — and it opens the door to automating everything that happens around your slides.

Think about what a full presentation workflow actually involves. Generating the deck inside Google Slides is one step; the rest looks something like this:

• Research pulls: gathering sources and evidence before you write a single prompt
• Data sourcing: pulling the numbers, charts, and citations that back each slide
• Follow-up deck variants: adapting a finished deck for different audiences or stakeholders
• Revision hygiene: tracking terminology changes across sections without breaking source footers

Agent skills — instruction packages written in SKILL.md format for tools like Claude Code, Codex, Cursor, and Gemini CLI — can handle much of that surrounding work. But there's a catch worth knowing: published research found that roughly 26% of agent skills carry at least one vulnerability. Skills are everywhere; knowing which ones actually help is the hard part.

That's the gap SkillzBench is building to close. It's a free, independent directory of AI agent skills that crawls and dedupes skills from GitHub, pins every version to a commit SHA, runs security scans and license checks, and benchmarks each skill in a sandbox — testing with and without the skill to publish a Lift score in percentage points. A free MCP connector (currently in development) will let you wire only the skills you choose into any agent. Everything on the platform stays free, and money never touches scores.

The practical takeaway is a clean division of labor. Use Plus AI for what it's demonstrably good at: in-editor generation and editing, where it can preserve your master slides, insert single slides in specific layouts, and Remix content — say, turning a paragraph into a three-column comparison — without losing anything. Hands-on testing found a 10-slide deck generates in about 2 minutes, which is on the slower side but workable inside a familiar editor. Note that Plus AI output is highly dependent on prompt quality, and there's no permanent free tier — just a 7-day trial.

Then use tested agent skills for everything around it: the research, the data pulls, the variants. Deckary's reviewer put it well — the real question isn't whether a tool can generate slides, but how well it handles your existing templates, revision cycles, and final artifact. Test before you trust, whether that's a presentation tool or a skill.
