## ■ Background and Challenges
[Image]
The following challenges are widely seen in corporate legal affairs and contract review operations.
**- It takes time to check differences with previous versions**
It is not uncommon to spend several hours searching for a few lines of changes within a contract spanning hundreds of pages.
**- Risk of overlooking changes**
The task of visually checking the entire text is a hotbed for human error, accompanied by the risk of missing important clause changes.
**- Concerns about information leakage associated with inputting data into general-purpose AI**
Security concerns regarding pasting the full text of a contract into a general-purpose AI tool hinder digitalization.
**- Personalization of managing contract and renewal deadlines**
In many cases, deadlines are managed via Excel or personal calendars. It is a common risk that contracts are automatically renewed or opportunities for cancellation are missed without noticing due to a change in personnel or a lapse in communication.
**- Inability to grasp silent revisions to SaaS terms of use**
The fact that a person in charge must actively check every time a revision occurs makes it difficult to manage.
