Nearly half of presenters (47 percent) still spend eight-plus hours building a single deck, according to WeShare’s 2025 survey. PlusAI reports that its in-slide add-in can flip a prompt into a 15-slide draft in under a minute, and an independent Toolify speed test clocked ten slides in two minutes. Those numbers help explain why reviewers on Zapier say marathon slide builds are “behind us.” In this guide, we timed ten leading generators to see which ones hand you back the most hours, so grab a coffee and start the clock.
How we measured real-world time savings
We paired a stopwatch test with a six-factor quality score to see where each AI tool saves time and where it costs you.
- Stopwatch test. We ran the same product-launch prompt in every generator and timed the seconds from clicking Generate to receiving an editable deck.
- Polish time. We then measured the minutes needed to reach client readiness: swap brand colors, refine copy, and export to PowerPoint or Google Slides.
- Six-factor score. Because raw minutes can hide extra effort, each tool also earned 1–5 points on:
- Idea-to-deck speed
- AI content quality
- Design consistency
- Ease of editing after generation
- Integration or export friction
- Collaboration features per dollar
Any stumble on a single factor erased the time saved up front. Only tools that balanced speed with quality advanced to the leaderboard snapshot below.

Deep dives: where the minutes disappear
The tests below use the same 15-slide product-launch brief and the timing method described earlier. Average generation and polish times are rounded to the nearest five seconds.
PlusAI: in-deck help that feels like a teammate
- Stopwatch: 45 seconds to a 15-slide draft (inside PowerPoint).
- Polish: 4 minutes after using Slide Remix and AI Rewrite.
Slide Remix swaps any awkward layout with one click, and Live Snapshot keeps charts current. A reviewer on Reddit writes, “It looks professional and saves me enough time to justify the subscription.”
Gamma: web app for cohesive decks, fast
- Stopwatch: 40 seconds in the browser.
- Polish: 6 minutes (add a few more if you export to .pptx).
Gamma’s strength is design uniformity; every slide shares the same palette, so you rarely chase rogue fonts. Presenting from a Gamma link avoids export cleanup.
Beautiful.ai: auto-layout that stays tidy
- Stopwatch: 55 seconds.
- Polish: 3 minutes to update charts and text; the AI re-flows everything automatically.
Teams that update decks weekly gain consistency without manual nudging, though highly custom designs can feel constrained.
Microsoft Copilot: a draft machine in the ribbon
- Stopwatch: 35 seconds for a five-slide outline.
- Polish: 8 minutes; you’ll flesh out sparse bullets and swap stock icons.
Copilot pulls charts from Word or Excel, but the first draft is skeletal, so plan on design work afterward.
Google Duet AI: slide-by-slide assistance
- Stopwatch: Not applicable (generates one slide at a time).
- Polish: Around 1 minute per slide for text or image inserts.
Duet shines at micro tasks, such as rewriting bullets or creating on-brand images, yet it cannot draft an entire deck in a single prompt.
Tome: scroll-based stories in record time
- Stopwatch: 30 seconds to a five-page narrative.
- Polish: 4 minutes; mainly image tweaks.
Ideal for early-stage concepts, but you’ll rebuild elsewhere if you need dense charts or a strict .pptx.
Pitch: collaboration first, AI second
- Stopwatch: 50 seconds with template auto-fill.
- Polish: Varies by team; real-time editing removes back-and-forth emails.
AI helps with small rewrites, but the main speed boost is simultaneous editing.
STORYD: frameworks that erase blank-slide panic
- Stopwatch: 35 seconds to a pre-structured outline.
- Polish: 5 minutes to tailor bullets and branding.
You trade deep design control for a ready-made persuasive flow.
Visme: AI draft plus a giant asset library
- Stopwatch: 45 seconds.
- Polish: 6 minutes; swapping assets is quick, thanks to the built-in library.
Visme works best when you also need infographics or social graphics that match the deck.
Prezi: cinematic zooms without storyboarding
- Stopwatch: 60 seconds to map topics and sub-topics.
- Polish: 7 minutes to fine-tune zoom paths and brand colors.
Great for keynotes; prepare for extra polish compared with slide-based tools. That focus on narrative flow echoes the wider shift toward AI-driven storytelling highlighted in this piece on how presentation tools are reshaping stories from Comic-Con panels to boardrooms.
Find your perfect match in three quick steps
- Check your home turf. If your team builds in PowerPoint or Google Slides, start with PlusAI, Copilot, or Duet.
- Rate collaboration needs. Heavy co-editing? Choose Pitch. Solo drafting? Gamma or Tome.
- Balance polish and flexibility. Beautiful.ai and Visme protect brand consistency, while Gamma and Prezi favor creative freedom.
Run the same prompt in your top two picks this week. If Generate fails to save at least five minutes, move on; another tool will.
PlusAI: in-deck assistant that cuts creation to two minutes
PlusAI lives inside PowerPoint and Google Slides, so you start and finish in the file your team already edits. The add-in generates up to 20 on-brand slides in about 1–2 minutes from a single prompt. This removes export hassles and font mismatches.
After generation, three one-click tools trim even more time:
- Slide Remix swaps any clunky layout without touching your text.
- Rewrite rephrases lengthy bullets for clarity.
- Live Snapshots embed charts that refresh on open, ideal for weekly metrics (source: PlusAI guide).
A user on Reddit notes, “It looks professional and saves me enough time to justify the subscription.” If your workflow runs on PowerPoint or Slides, PlusAI works like a silent teammate. It drafts, refines, and updates decks while you focus on the story.
Gamma: web app that builds cohesive decks in under a minute
Gamma’s AI turns a plain prompt into a 15-slide deck in about 40 seconds. Every slide shares the same theme, so you rarely chase rogue fonts.
Why it saves time
- One-click generation delivers a consistent deck; we needed 6 minutes of tweaks—mostly wording—before it was client-ready.
- An advanced settings panel lets you set tone, slide count, and image style up front, reducing back-and-forth edits.
- Share via a Gamma link to skip file conversions; exporting to PowerPoint can alter gradients and some fonts, adding a few cleanup minutes.
Gamma excels when you can present online and care most about visual harmony. Budget a little extra time if your workflow still ends in .pptx.
Beautiful.ai: smart layouts that stay tidy
Beautiful.ai’s Smart Slides re-flow content automatically, so one extra bullet never wrecks your design. In Zapier’s 2025 hands-on test, a 12-slide marketing report refreshed “without dragging things around manually.”
Speed in our test
- Draft generation: 50 seconds for a 12-slide deck.
- Polish: 3 minutes to swap data and logos; Smart Slides kept the layout intact.
Best for teams that update decks every week—KPIs, timelines, or stakeholder check-ins—because replacing last month’s figures keeps every chart, font, and color on brand. If you need highly custom art, the guardrails can feel tight; otherwise, the auto-layout saves a full reporting cycle of manual tweaks.
Microsoft Copilot: draft machine in the ribbon
- Stopwatch: 35 seconds for a five-slide outline.
- Polish: 8 minutes; you’ll flesh out sparse bullets and swap stock icons.
Copilot pulls charts directly from Word or Excel, but the first draft is thin, so plan on extra design work before you present.
Google Duet AI: slide-by-slide assistance
- Stopwatch: Not applicable; the tool generates one slide at a time.
- Polish: Around 1 minute per slide for text or image inserts.
Duet excels at micro tasks such as rewriting bullets or creating on-brand images, yet it cannot draft an entire deck from a single prompt.
Tome: scroll-based stories in record time
- Stopwatch: 30 seconds to a five-page narrative.
- Polish: 4 minutes; mostly image tweaks.
Tome works well for rapid concept pitches, but you’ll likely rebuild in another tool if you need detailed charts or a PowerPoint hand-off.
Pitch: real-time team editing
- Stopwatch: 50 seconds with template auto-fill.
- Polish: Time varies by team; live editing replaces long email threads.
Pitch centers on collaboration. The AI offers light text tweaks, but the main speed boost comes from teammates editing together and seeing feedback instantly.
STORYD: frameworks that erase blank-slide worry
- Stopwatch: 35 seconds to a pre-structured outline.
- Polish: 5 minutes to tailor bullets, branding, and colors.
You give up some design freedom in exchange for a ready-made persuasive flow.
Visme: AI draft plus a large asset library
- Stopwatch: 45 seconds.
- Polish: 6 minutes; swapping assets is quick, thanks to the built-in library.
Visme shines when you also need infographics or social graphics that match the deck.
Prezi: cinematic zooms without storyboarding
- Stopwatch: 60 seconds to map topics and sub-topics.
- Polish: 7 minutes to adjust zoom paths and brand colors.
Prezi excels at high-impact keynotes, but plan a few extra minutes to refine the cinematic moves compared with slide-based tools.
Future trends worth bookmarking
AI presentation tools change fast. Keep an eye on these three shifts, all backed by public road maps and beta notes.
1. Full-deck generation inside Office suites (Q4 2025).
- Microsoft 365 Copilot’s May 2025 Insider build added “Design Suggestions,” which turns a prompt into a multi-slide deck, complete with custom templates, in one action (source: Microsoft 365 Insider blog).
- Google’s June 2025 Workspace drop previewed Veo 3 in Slides and Vids, promising AI-generated presentations “in a fraction of the time” (source: Google Workspace blog).
2. Hyper-niche generators.
Start-ups now target single use cases such as investor pitch decks, academic lectures, and wedding toasts. Funding trackers on Product Hunt list 12 new “AI presentations” launches in May 2025 alone, and the pace is rising each quarter.
3. Live data and voice-guided editing.
- PlusAI already refreshes dashboard charts when you open a deck, and Microsoft’s April 21 2025 Copilot update can pull a fresh slide from any linked file in seconds (source: Microsoft 365 Insider blog).
- Prezi’s March 2025 beta lets presenters narrate edits aloud while the AI rearranges objects on-screen, marking an early move toward voice-driven design.
Action item: Schedule a quarterly 15-minute check-in to review release notes for your top two tools. In presentation tech, today’s limit often becomes next quarter’s shortcut.
Conclusion
Slide design shouldn’t take a full workday. Research shows 47 percent of presenters still spend eight or more hours per deck, time you can reclaim with the right AI assistant. Time two frontrunners against the same 10-slide prompt; if one shortens the process to under 15 minutes, you’ve found your match.
Let the generator handle layouts and boilerplate. Then invest your saved hours in story, data, and delivery. When you’re ready for deeper marketing insights, ModernMarketingPartners is just one click away.
FAQ
What is an AI presentation generator?
An AI presentation generator is a software tool that automatically creates slide decks based on a prompt or input outline. These tools use machine learning to generate text, design layouts, choose visuals, and even suggest a full presentation structure—saving users hours of manual formatting.
