The reason making presentation materials takes so long isn’t the time spent drawing slides. It’s the time spent sitting in front of a blank page, unable to decide on the structure. The value of AI presentation tools lies exactly there. Give it a topic, and a table of contents and draft slides appear in seconds; instead of a blank screen, the person faces something to edit.
The problem comes next. There are constant cases where people take the draft as-is, thinking “this should be enough,” only to crumble in the meeting room. Therefore, this article focuses more on drawing the line between what to delegate and where to step in, rather than just introducing the tools.
What AI Presentation Tools Actually Do
They are strong in three areas.
First, structuring. Even just entering “New Hire Onboarding Process Improvement Plan” builds a skeleton like Current Status → Problem → Alternative → Execution Plan. This is valuable not because it’s the best structure, but because it gives you something to refine. Humans are much better at critiquing someone else’s draft than creating from nothing.
Second, draft slides. It fills in sentences and bullets for each page. Most are generic, but if you have ten generic slides, you can use three or four as-is and focus on the rest.
Third, design consistency. When humans make them manually, font sizes and margins shift subtly from page to page. AI tools align everything to the same rules once a theme is chosen. Those with less design sense feel this benefit the most.
Conversely, what they can’t do is clear: data accuracy, company-specific templates, and judgments like “What is the one thing the audience should remember from this slide?” The first two are functional limitations; the last one is the presenter’s original job.
Trying Gamma
Gamma’s results vary greatly depending on the input.
- Giving just a one-line topic: You get a generic slide. This is natural since it doesn’t know your company name or team situation. It’s useful for brainstorming but insufficient for an actual presentation.
- Giving an outline (TOC): Results improve noticeably. The division of labor where the human sets the order and the AI adds the meat works best.
- Giving an entire existing document: This is the best. If you input meeting minutes or a proposal, it rearranges existing content into a slide format, reducing the chance of factual errors.
Editing is also quite easy. Rewriting paragraphs or changing layouts by card unit is intuitive. The sticking point is precise positioning. If you try to move shapes pixel by pixel like in PowerPoint, it gets frustrating. It’s not a tool meant for that purpose in the first place.
Trying Tome
Even with the same topic, Tome leans more toward a narrative-driven style. Since it builds flow with large images and short sentences on each page, it suits presentations that need emotional resonance, like product intros or pitches.
Conversely, it’s not well-suited for data-heavy business reports. Once you start packing in tables and figures, the whitespace—its original strength—disappears, making it mediocre.
In summary: Gamma is a better starting point for business reports and internal sharing, while Tome is better for external pitches and introductory materials. Since both allow you to try a few for free, putting the same topic into both and choosing is faster than any comparison article.
What Breaks When Exporting to PowerPoint
This is where people lose the most time. Exporting is possible, but it doesn’t come out exactly like the original.
- Fonts: If the web font isn’t on your local machine, it’s replaced by a substitute. This happens often with Korean fonts, and as line break positions shift, text can spill out of boxes.
- Layout: Spacing that was set by auto-alignment converts to fixed coordinates, causing subtle misalignments.
- Animations/Transitions: It’s safest to assume most will be lost.
Realistic solutions are twofold: present directly from the web, or factor “cleanup time after export” into your schedule. If you’re in an organization that must use a company template, it’s better to reverse the order. Extract only the structure and sentences from the AI tool, then copy and fill them into the actual slides on the company template. You give up the advantage of design consistency but avoid formatting disasters right before the deadline.
Parts That Must Be Done by Hand
To summarize in one sentence: Anything where being wrong causes trouble must be checked by a human.
- Numbers: Figures filled in by AI might just be plausible placeholders. Cross-check them line by line with the original data.
- Sources: Check if cited statistics have sources and if those sources actually exist.
- Conclusion: The last slide of a draft is usually generic and bland. Only the presenter can write what actually needs to be decided.
If you skip these three, you’ll pay the price for making the materials quickly in the meeting room. Conversely, if a human handles just these three, the rest of the time is significantly reduced.

Frequently Asked Questions
How much can I do for free?
Both services allow you to create a few materials with free credits, but there are limits on the number of generations, and the free plan often restricts exporting or removing branding. If you plan to use it continuously for work, it’s realistic to assume you’ll need a paid subscription.
Do Korean presentation materials turn out well?
Sentence generation itself is fine. The issue is formatting. Korean characters are wider than English ones, which can make line breaks awkward in auto-layouts, and fonts often change during PowerPoint export, causing text overflow. Always check on the actual screen after completion.
Can I apply a company template?
Only partially. You can match colors and fonts, but using a set master slide as-is is difficult. For organizations where template compliance is mandatory, we recommend extracting only the structure and sentences from the AI tool and building the slides on the company template.
Does it create a presentation script?
There is a feature to generate presentation notes for each slide. However, the output is essentially a paraphrased version of what’s on the slide, so reading it as-is will just repeat what’s on the screen. It’s best used as a draft to be converted into your own words.
