Secure "Notebook AI" Service for Corporations Implements Custom Instructions Feature

Knowledge Sense Inc. (Headquarters: Minato-ku, Tokyo; CEO: Atsushi Kadowaki; hereinafter referred to as Knowledge Sense) is pleased to announce that the "Custom Instructions" feature, which allows users to specify response policies and preconditions for each Notebook, has been released today, June 30, 2026, for the Notebook function of our secure generative AI agent for corporations, "ChatSense".

Secure "Notebook AI" Service for Corporations Implements Custom Instructions Feature

ChatSense offers a corporate "Notebook AI" service that allows users to add documents as sources and ask questions, summarize, or create slides based on their content. Following the recent beta release, we have continued to expand our features and have now implemented the "Custom Instructions" function, enabling users to specify response policies and preconditions for each Notebook. For more details, please contact us. https://chatsense.jp/contact

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 security and its ability to perform additional learning with internal data, leading to its adoption by over 500 companies, including major corporations listed on the Tokyo Stock Exchange Prime Market.

Since the beta version of ChatSense's Notebook function was released on June 22, 2026, as an AI service for corporations that can generate content based on documents, it has been used by many user companies. However, we have received numerous requests from users in the field, such as "It's troublesome to rewrite the preconditions for every question when the preconditions and response policies differ for each Notebook," "I want to differentiate between a sales document Notebook that should answer in plain language and a technical specification Notebook that should answer with precise technical terms," and "I want to change the AI's response style for external and internal communications."

In response to these requests, we are releasing the "Custom Instructions" feature today, June 30, 2026, which allows users to specify response policies and preconditions for each Notebook. The settings applied to a Notebook will be automatically reflected in every response within that Notebook. This eliminates the need to re-enter preconditions with each question and allows users to fix the response style according to the nature of the project or document on a Notebook-by-Notebook basis.

Feature Highlights

1. Specify Response Policies and Preconditions for Each Notebook

Users can freely specify response policies and preconditions for a Notebook, such as "Replace technical terms with plain language," "Always include the page number of the source," or "Respond in a polite tone for external communications." The set content will be automatically reflected in every response within that Notebook.

2. Reduce the Effort of Rewriting Preconditions for Each Question

Once set as custom instructions, there is no need to re-enter preconditions or response styles with every question. Users can elicit responses optimized for the nature of the document or project with just a short prompt.

3. Unify Response Styles on a Notebook-by-Notebook Basis

Response styles can be differentiated according to the purpose of the Notebook, such as sales documents, technical specifications, external FAQs, or internal operational manuals. Since members sharing a Notebook will receive responses with the same preconditions and tone, variations in response quality across the organization can be reduced.

What is the Corporate ChatGPT Service "ChatSense"?

"ChatGPT" is a type of large language model released by OpenAI in the fall of 2022. ChatSense, provided by Knowledge Sense, is a service that offers the advantages of ChatGPT with enhanced security and cost-effectiveness, aiming to improve the operational efficiency of corporations and local governments. It has the following features:

1. Function to Protect Chat Content from AI Learning

This is a common feature available for all plans: Enterprise Plan, Standard Plan, and the free Starter Plan.

2. Abundant Original Features, Including the Ability to Share Prompts Internally

Features for corporate contracts not found in regular ChatGPT are a key characteristic. In addition, features such as bulk member management and folder & drag-and-drop organization are updated daily, and most of them are available even from the free plan.

3. ChatSense Has No Initial Costs and No Minimum Usage Period Commitment

To address the "we won't know until we try" sentiment of companies, we have lowered the barrier to adoption as much as possible and significantly expanded the scope of free usage.
