Tokyo, Japan — Kotozna, Inc. (Head Office: Minato-ku, Tokyo; CEO: Genri Goto), a B2B SaaS company specializing in generative AI–powered multilingual communication platforms, announced new automation features in Kotozna TPG 2.0 on Tuesday, March 24, 2026. With this update, users can create high-accuracy AI chatbots with a one-click setup by simply inputting a document or website URL.

As organizations increasingly adopt generative AI for customer support and knowledge management, building chatbots often requires extensive manual preparation of data sources and ongoing maintenance. The new capabilities in TPG 2.0 significantly reduce these barriers by automating content extraction and structuring.
With the latest update, users can now generate knowledge-based chatbots quickly while maintaining Kotozna’s core strengths of high response accuracy and low operational maintenance.

“The goal of TPG 2.0 is to make generative AI tools accessible to anyone,” said Genri Goto, CEO of Kotozna. “With automated document and website processing, organizations can easily build reliable chatbots and significantly improve inquiry handling efficiency.”

● Key New Features in TPG 2.0
① Enhanced PDF Chunker for Large and Complex Documents:
TPG 2.0 now includes an enhanced PDF Chunker capable of processing large documents, including files exceeding 50 pages. The system can automatically extract information not only from text but also from structured elements such as tables.
This functionality is particularly useful for materials such as product manuals, financial reports, and investor relations documents, enabling organizations to quickly transform detailed documentation into interactive chatbot knowledge bases.

② New Web Chunker for Automatic Website-Based Chatbots:
The platform also introduces a Web Chunker, enabling users to create a chatbot simply by entering a single website URL. The system automatically crawls and categorizes relevant pages within the same domain, organizing the information into a structured knowledge base.
This capability makes it easy for businesses—especially in sectors such as tourism, retail, and preventive healthcare—to rapidly generate comprehensive chatbots that can answer customer inquiries using existing website content.

● Expanding Accessibility of Generative AI
These features make it significantly easier for organizations to deploy chatbots using their existing content. By reducing the technical complexity and setup time, TPG 2.0 enables businesses to deploy AI-powered communication tools in minutes while ensuring consistent responses and minimizing maintenance effort. Even SMEs can now quickly generate comprehensive, high-performing assistants using publicly available website information or documentation.

By combining high accuracy, low maintenance requirements, and one-click setup, TPG 2.0 positions itself as one of the most accessible generative AI chatbot platforms for businesses.

The platform has already generated strong interest from major manufacturers and leading corporations in Japan, driven by its ability to reduce repetitive inquiries and improve operational efficiency. A free plan is also available for individuals and organizations to explore the platform.
