Keywalker's Web monitoring tool "CERVN" received a major update after about 2 years and 4 months, integrating AI functions (importance judgment, summarization, prompt) and a revamped management screen to maximize operational efficiency.

Keywalker Inc. (Headquarters: Minato-ku, Tokyo; President & CEO: Kazuto Kobayashi; hereinafter "the Company") is pleased to announce a significant update to its service, "Web Monitoring Automation Tool: CERVN," which has further enhanced the efficiency of Web monitoring operations.

**About Web Monitoring Automation Tool: CERVN** "CERVN" is a Web monitoring automation tool that automatically detects and notifies users of updates and differential information on Web pages. It continuously monitors ever-changing Web information without relying on manual effort, quickly catching important changes and updates, thereby streamlining customers' information gathering tasks.

**Details of This Update** This major update primarily consists of the following four points: **① Equipped with "AI Importance Function"** The newly implemented "AI Importance Function" automatically determines the importance of updated information and notifies users with prioritized alerts. This enables "notifications focused only on highly important information," significantly reducing the man-hours previously spent on checking vast amounts of new information. It maximizes operational efficiency while preventing information oversight.

**② Equipped with "AI Summarization Function"** The new "AI Summarization Function" has also been implemented. This function automatically analyzes updated information using AI and summarizes the key points in text format for notification. This eliminates the "effort of checking each page individually" that was previously required, allowing users to focus solely on "necessary actions" from a vast amount of information by simply reviewing the summaries.

**③ Equipped with "Prompt Function"** A "Prompt Function" that allows users to give detailed instructions to the AI has also been added. By writing arbitrary prompts (instruction sentences), the AI performs prioritization and summarization based on those prompts, making it possible to detect necessary information with high accuracy.

**④ Updated to a Sophisticated Management Screen for Enhanced Usability** The management screen has also undergone a major renewal, the first in approximately 2 years and 4 months. Pursuing usability, it has been updated to a design that combines intuitive operation with high visibility. By significantly reducing the time required to check information, it creates an environment where users can concentrate more on high-priority tasks they should be focusing on.

The Company will continue to improve the functions of "CERVN" and contribute to enhancing the efficiency of Web monitoring operations for more companies, supporting more advanced management.

**Company Overview** Keywalker provides services ranging from collecting external data, including websites, to integrating it with data held within companies for analysis and visualization, to various companies and research institutions. By visualizing collected data, it becomes possible to gain new insights, explore excellent actions, improve productivity and cost efficiency, and accelerate management decisions.
