AI Chatbot and AI Blog Assistant Introduced to "CAREECON Plus" Marketing Functions

BRANU Inc. (Headquarters: Minato-ku, Tokyo; Representative Director: Tatsuya Natomi; Securities Code: 460A; hereinafter "BRANU"), which operates a construction DX platform business, has updated the marketing functions of "CAREECON Plus," an integrated business tool for the construction industry, to include an "AI Chatbot" and an "AI Blog Assistant," which will be available from May 11, 2026.

Development Background

In the construction industry, while the importance of customer acquisition through websites is increasing, much of the inquiry handling and information dissemination still relies on human effort, often making it difficult to provide sufficient support and ensure continuous operation.

In particular, content marketing utilizing owned media such as blogs is an effective means to deliver information tailored to customer issues and search intent, creating touchpoints with potential customers. However, in the construction industry, where construction methods, service areas, and strengths vary by company, specialized knowledge is required for theme design, content creation, and customer support.

Additionally, inquiry handling, customer follow-up, and blog operations are often performed by individuals, requiring significant effort for effective operation. As a result, many companies are unable to fully engage in customer acquisition and information dissemination using their websites.

To address these challenges, BRANU has been working to build a system that supports and automates information dissemination and customer support, traditionally handled by humans, using AI, leveraging the corporate and industry data accumulated through "CAREECON Platform."

With this update, by utilizing AI, we enable automated customer support on websites and optimized content generation for each company, providing integrated support for the entire process from acquiring potential customers to closing deals.

About "AI Chatbot"

This function allows the "AI Chatbot" to be installed on the client company's website via CMS, enabling AI to automatically respond to inquiries and questions from visiting users.

Since the LLM generates responses based on each company's website information, optimal responses can be provided according to the specific construction methods, service areas, and service characteristics of each company. The generative chatbot, independent of scenarios, flexibly responds to diverse user questions.

Furthermore, inquiry details and response history are accumulated as customer data, and by linking with CRM, operations can be managed with a view to deal closing. This not only automates responses outside business hours and initial responses but also creates a mechanism to capture and utilize potential customer touchpoints without missing them.

In addition, by accumulating and utilizing actual inquiry content and operational data as training data for AI, the LLM's response accuracy and quality are continuously improved, realizing customer support optimized for each company.

About "AI Blog Assistant"

"AI Blog Assistant" is a function that integrates and analyzes corporate data and industry data of the construction industry accumulated through "CAREECON Platform" with our AI platform "BRANU BRAIN." It analyzes the corporate culture and business characteristics to generate optimized content for each company.

This function is an update to the previously offered "AI Blog Assistant." In addition to the client company's website information, construction details, and service areas, AI analyzes video data recorded during interviews and reflects the extracted corporate culture and tone of voice, generating unique content that is not uniform.

Furthermore, it supports theme design based on target customers and search intent, as well as the creation of annual posting plans. Strategic content marketing is possible with keyword design conscious of AIO (AI Optimization) and based on anticipated user questions.

This automates content planning, production, and operation, which were traditionally individual-dependent and difficult to sustain, leading to traffic acquisition and nurturing of potential customers.

Marketing Ecosystem where AI and Data Circulate

"AI Chatbot" and "AI Blog Assistant" build an ecosystem where data obtained from each mutually complements and utilizes the other, improving accuracy and quality the more they are used. Through this data circulation, understanding of each company's characteristics and user needs deepens, continuously evolving into more optimal information dissemination and customer support.

BRANU will continue to promote the creation of an environment where the construction industry can concentrate on tasks that should exert their inherent value by automating the workload traditionally handled by humans with AI, through "red growth" where the product itself continuously enhances its value through use.
