Kotozna TPG 2.0 Generative AI Chatbot Builder

Kotozna, Inc. is a Tokyo B2B SaaS company founded in October 2016 that builds generative AI tools for multilingual communication. It has offices in Tokyo, Fukuoka, Zhuhai (China) and Singapore, and serves hotels, malls, tourism bodies and corporations in Japan, the US, Thailand and Singapore with products such as the Kotozna In-room guest app and the ConcierGAI tourism chatbot.

Kotozna TPG 2.0, released in January 2026, lets organizations build generative AI chatbots without prompt engineering. Instant Setup turns uploaded PDFs such as manuals, policies or FAQs into a working chatbot in about five minutes, while Custom Setup combines websites, PDFs and spreadsheets with role templates in about ten minutes. A March 2026 update added a PDF chunker for documents over 50 pages including tables, a web chunker that builds a knowledge base from a single URL, and pre-launch testing. Kotozna uses its own knowledge-based prompt creation technique instead of conventional RAG to reduce hallucinations and gives multilingual answers.

• Instant Setup: creates a chatbot from uploaded PDFs such as manuals, policies and FAQs in about five minutes.
• Custom Setup: combines websites, PDFs and spreadsheets with role and behavior templates.
• PDF chunker: processes documents over 50 pages and extracts data from tables as well as text.
• Web chunker: crawls and categorizes pages from a single URL into a structured knowledge base.
• Knowledge-based prompt creation: proprietary alternative to conventional RAG aimed at fewer hallucinations.
• Pre-launch testing: lets teams test, refine and validate chatbot answers before release.

Hotels and resorts in Vietnam can build multilingual guest FAQ chatbots from existing brochures and websites. Japanese-owned factories can turn HR, safety and expense policies into an internal assistant for Vietnamese and Japanese staff. Listed companies can answer investor questions from annual reports and earnings releases.

Business teams can launch a document-grounded chatbot in about five to ten minutes without engineers or prompt skills. Pricing starts at 9,800 JPY per month with a free plan for evaluation, which suits pilots by individual departments. Multilingual answers serve foreign customers and staff from the same knowledge base, and one-click updates from PDFs and websites reduce ongoing maintenance.

Departments want to deploy document-grounded AI assistants themselves rather than wait for IT projects, and low monthly pricing makes small pilots easy. Tourism, retail and manufacturing in Asia serve growing numbers of foreign visitors and multinational staff, so multilingual answers from one knowledge base are in demand, including in Vietnam's tourism and FDI sectors.

Kotozna, Inc. was founded in October 2016 and is headquartered in Akasaka, Minato-ku, Tokyo, with offices in Fukuoka, Zhuhai and Singapore; CEO Genri Goto. Capital was 212.5 million JPY as of August 2024, with over 30 employees and 500+ tourism clients cited. In April 2025 it began a collaboration with Glad Cube to expand multilingual generative AI services.
