Presentation format documents are used for nearly all communication purposes, including internal company communication, inter-company collaboration, fundraising, product launches, training sessions, and lectures.
The challenge is that it often takes several days to complete from content composition to finalizing the design in PPT.
As we enter the era of generative AI, tools like Gamma, known as AI for creating PPT, have emerged to handle design and slide composition tasks swiftly.
However, to achieve depth in content and create a customized storyline, human editing remains necessary.
This article introduces the latest features and pricing plans of Gamma, reviews pros and cons from actual users, and shows how the integration of Gamma with inlineAI can simultaneously complete custom storylines and design.

Reasons PPT Creation AI is In the Spotlight
According to a survey conducted in 2025 by Dropbox in major countries, including Korea, 68% of employees in our country spend up to 10 hours a week on repetitive tasks like writing reports and materials.
Furthermore, more than half of the respondents expressed willingness to actively adopt AI if it could save more than 4 hours per week.
Thus, employees are currently spending a lot of time on repetitive document creation and feeling its inefficiency. There is a perceived need to resolve this issue with AI.
Reducing document creation time for PPT-like documents is not merely about convenience, but is becoming an essential aspect of work efficiency and productivity.
AI for creating PPT offers a solution by capturing both design quality and reduced production time.

Challenges in Practical Application of Gamma.app
However, compiling reviews from practitioners shows limitations in fully automating PPTs with just Gamma.
Concerns on Content Completeness
While Gamma generates slides according to given keywords and sentences, it struggles to deeply reflect a company's unique data, brand story, and audience-specific logic due to its prompt-driven style generation.
Difficulty in Partial Edits
Gamma faces challenges in handling 'fine-tuned modifications.' Modifying part of the slide content can disrupt the overall structure or make the flow unnatural.
Limitations in Reflecting Language and Cultural Context
For non-English speakers, especially in the Korean language environment, sentences may appear awkward. It may also lack reflection on domestic market data and local cultural codes.
Security Vulnerability Due to Cloud-based Nature
Due to the cloud-based service nature, there is a concern about leaking when uploading confidential or sensitive data.
In conclusion, while Gamma shows strengths as a presentation creation AI, there are some drawbacks when assisting in-depth document creation.
This is why it should be used in conjunction with a document automation creation AI.

Successful Cases of Using PPT Creation AI Gamma with inlineAI
The combination of Gamma, a PPT auto-creation AI, and inlineAI, a document writing AI, demonstrates effectiveness in diverse situations.
✅ Case Study for IR Material Production: Successful Fundraising
Startup A was preparing for Series A investment.
The initially simple IR material created with Gamma had a neat design, but lacked persuasion in key data such as sales growth trends, customer acquisition strategies, and financial forecasts. Additionally, it had trouble standing out due to similar structures with other startup IRs.
Company A input last 3 years of sales data, a list of major customer performance, performance metrics, and future growth plans into inlineAI.
inlineAI analyzed the data and crafted a customized storyline in the sequence of 'Problem Recognition -> Solution -> Performance -> Scalability,' and summarized key sentences appealing to investors for PPT slides.
When the draft was brought into Gamma, it arranged visually impactful charts, infographics, and timelines, completing a more competent IR deck.
The final material, blended with Gamma for design and inlineAI for content, was praised as 'concise yet essential,' leading to successful fundraising in the investor meeting.
✅ Strategic Report PPT: 70% Reduction in Production Time
The strategic planning team at mid-sized company C was tasked to review quarterly results and report future strategies at an executive meeting.
Initially completing the presentation draft with Gamma resulted in a simple list of figures and indicators lacking explanations on 'why these figures matter.'
The team input ERP data, sales/cost analysis tables, and market trend reports into inlineAI.
Analyzing the data, inlineAI clearly described the past quarter's performance change reasons, comparison with competitor trends, and three main strategies for the next quarter. This content was visualized by Gamma to create a KPI achievement rate gauge, SWOT analysis slide, and strategy roadmap diagram.
They successfully completed the report by reducing report creation time by 70%.
