Knowledge Sense Inc. (Headquarters: Minato-ku, Tokyo; CEO: Atsushi Kadowaki; hereinafter "Knowledge Sense") announces that it plans to roll out the beta version of "Notebook," a feature that allows users to ask AI questions while referencing documents, for ChatSense Business Plan users starting next week. Furthermore, upon full deployment, this feature is planned to be provided within the scope of the regular Business Plan pricing, allowing all Business Plan users to utilize it in sufficient quantities.
Highly Secure "Notebook" AI Service, Beta Version Rollout Begins
The "Notebook" feature allows users to add documents such as PDF and Office files as sources, and then ask AI questions about the selected sources or create derived outputs like summaries, briefings, and slides. The beta version of this Notebook feature is scheduled to be progressively rolled out to ChatSense users starting next week (week of June 15, 2026). We are also continuing to recruit beta testers.

■ Background of the Release
Generative AI, including ChatGPT, is being adopted by many corporations to improve operational efficiency and service quality. Knowledge Sense's "ChatSense" has also gained attention for its strengths in providing a highly secure environment and features for in-house data fine-tuning, leading to adoption by over 500 companies, including major corporations listed on the Tokyo Stock Exchange Prime market.
However, many users in the field have expressed a need to "ask AI questions while reading through their current documents" and "interact with AI using internal documents and PDFs directly as sources." While standard chat functions are suitable for question-based conversations, they are not ideal for continuous dialogue tied to specific documents. Additionally, similar features like "fine-tuned AI" (RAG functionality) are designed with the premise of handling an organization's large-scale knowledge base, posing a challenge for individuals needing to quickly read and query their own documents.
To address these challenges, the beta version of the file-source-centric "Notebook" feature is scheduled for phased rollout to Business Plan users starting the week of June 15, 2026. The pricing structure will ensure that all users can utilize the feature in sufficient quantities within the scope of their existing Business Plan, with no need for additional contracts or individual options. This will enable smoother utilization for tasks such as checking key points, research, and preparing materials for document creation by loading PDFs and internal documents.

■ Feature Characteristics (Planned)
1. Add Files as Sources and Organize by Document
Users can add documents such as PDF and Office files as sources and manage them collectively within Notebooks. By having a dedicated conversational environment for each document, multiple documents can be handled efficiently.
2. Ask AI Questions and Converse Based on Selected Sources
Users can select sources within a Notebook and ask AI questions about their content. The AI will provide answers based on the selected sources, allowing for in-depth exploration while accurately referencing document content. This will streamline tasks such as reading, summarizing, and Q&A for reports, proposals, and specifications.
3. Sufficient Usage within Business Plan Scope, No Additional Charges
This feature is planned to be provided within the scope of the ChatSense Business Plan pricing, allowing all Business Plan users to utilize it in sufficient quantities. No additional contracts or individual options are required, and users can fully utilize the Notebook feature with their current Business Plan subscription.
