update it, Inc. has released the latest version (ver 3.0.3) of "crossnote," a documentation platform that enables efficient document creation and management for multiple users.

This update significantly enhances AI capabilities, including support for Anthropic's "Claude," as well as new AI agent functions, AI review features, and automation for routine tasks. The reason crossnote is utilized in environments requiring strict security standards, such as major automotive manufacturers and pharmaceutical companies, is its ability to leverage the latest AI within on-premises and closed-network environments without exposing highly confidential internal data to the outside. With these AI enhancements, crossnote provides even more powerful support for the "tedious documentation work" that occurs daily in manufacturing and quality assurance, helping to achieve both operational efficiency and improved quality.

"Tedious Verification Work" That Plagues the Workplace In the operation of documents such as specifications, periodic reports, and manuals, personnel spend a significant amount of time on verification tasks.

- Visually searching for and verifying changes in specifications that are dozens of pages long. - Comparing multiple files to ensure there are no contradictions with past versions or related documents. - Losing track of the latest version after editing by multiple people, leading to missed corrections or regressions. - Meticulously checking for inconsistent terminology or violations of internal rules.

crossnote supports these verification tasks, which previously relied on visual inspection, with AI agents, thereby reducing the burden on personnel and improving verification quality.

Leveraging AI While Protecting Confidential Data Many companies feel uneasy about feeding specifications or reports containing confidential information into general-purpose AI. crossnote supports configurations that can be used safely within a customer's dedicated on-premises or closed-network environment.

This update adds support for Anthropic's "Claude." Claude is a powerful AI on par with ChatGPT and Gemini, and is currently attracting attention as one of the most dynamic AIs available. By setting an API key, you can execute various AI tasks using Claude within crossnote.

Furthermore, in addition to ChatGPT, Gemini, Claude, and local LLMs, crossnote also supports Sakura Internet's "Sakura AI Engine," making it possible to utilize open-source models in a closed-network configuration.

Key Points Enhanced in the Update The following functions have been added or enhanced in this update:

AI Support for Word, Excel, and PDF By utilizing ChatGPT's Code Interpreter and Claude's Analysis tool, support for editing Word documents and Excel files has been added. Additionally, AI review for PDF files is now supported, allowing for reviews that take into account information beyond just text.

Advanced AI Review Functionality By operating AI reviews on an agent-based model, the system can now read perspectives relevant to the review target from related files, enabling more flexible and practical reviews. It also supports reviews based on rules and guidelines, consistency checks, and the suggestion of corrections.

Automation of Routine Tasks An agent mode has been added to custom tasks. Registered AI tasks can be automatically executed at specific timings, such as when saving, opening a file, or just before a commit, helping to streamline repetitive daily verification work.

Improved Usability for AI Utilization A viewer that displays AI processing results clearly and an AI console that allows for centralized management of AI-related history are now available, improving the usability of AI integration.

About crossnote crossnote is a documentation platform for efficiently creating and maintaining thick specifications, periodic reports, manuals, and more with multiple users. While maintaining a "what you see is what you get" operability similar to Word, it integrates history management, reviews, search, comparison, and AI support.

Track Record crossnote is used by customers in the following industries: - Automotive manufacturers - Pharmaceutical companies / CROs (Contract Research Organizations) - Semiconductor manufacturers - Life insurance companies / Asset management companies - Major beverage manufacturers
