A Complete Comparison of Document Automation AI: MS Copilot vs Inline AI
What is the best generative AI for document creation for our company?
Recently, many companies are seriously considering the adoption of document automation AI. This is due to inefficiencies and practical challenges caused by repetitive document tasks that prevent concentration on core competencies.
According to a survey by a productivity-focused company, office workers spend over 3-4 hours a day on repetitive tasks such as updating Excel, spreadsheets, and Word documents. The Korea Productivity Center reports that Korean office workers spend about 52% of their work time on document-related tasks.
When you also consider the time spent on daily and weekly meetings, replying to emails, etc., there is often only an hour or two each day for companies to focus on productivity enhancement and highly strategic tasks.
As an alternative to improve such inefficient work structures, generative AI-based document automation solutions are rapidly spreading. This is because, beyond saving time, they offer positive effects such as cost reduction, improved employee satisfaction, and creating an environment where one can concentrate on core tasks, thereby enhancing overall organizational productivity.

Document Automation AI - MS Copilot vs Inline AI
For automation related to document tasks, tools like ChatGPT, Gemini, and Claude, which employ general-purpose generative AI, are frequently used.
However, general generative AI is not specialized in document task functions, so compared to the role of a 'Second Brain' that aids strategic thinking, its proficiency in document automation is somewhat lacking.
For those interested in document automation, it's advisable to use AI specialized for document tasks.
It's best to use AI developed directly by companies that originally created document tools or AI designed solely for document tasks.
The most notable enterprise document AIs currently on the market are Microsoft Copilot and Inline AI.
Microsoft Copilot offers the significant advantage of utilizing AI features naturally in existing work environments through robust integration with MS Office 365, including Word, Excel, PowerPoint, Outlook, and Teams.
If your company primarily uses MS Office and you regularly use MS Word and Excel, even Outlook and Teams, then Copilot is a document AI that you can use without barriers while reducing implementation costs.
Inline AI automatically generates documents perfectly matching the report formats and document templates actually used within the company. This function draws significant attention recently because it handles tasks that MS Copilot, ChatGPT, Claude, and other advanced global generative AI tools cannot.
If you frequently produce documents like reports, quotes, inspection notes, and proposals matching specific formats, introducing Inline AI will enable you to complete format document tasks that once took hours in mere seconds.
Given the ability to generate custom documents for your company, it's an excellent tool to complement general-purpose generative AI.
Both solutions share the common goal of expediting document creation and improving work efficiency, but they exhibit distinct strengths in security, customization, and internal system integration required in real corporate environments.
Choices may vary depending on our company's work processes, security policies, and document management systems.
This article has compiled a selection guide for the core features, corporate characteristics, and practical environments of these two solutions.
