update it, Inc. has released the latest version (ver 3.0.3) of 'crossnote', a documentation platform that enables efficient document creation and management by multiple users.
With this update, we have significantly enhanced features, including support for Anthropic's 'Claude', AI agent functions, AI review capabilities, and the automation of routine tasks. The reason crossnote is utilized on frontlines demanding strict security standards, such as major auto manufacturers and pharmaceutical companies, is that it allows the use of the latest AI in on-premise and closed network environments without taking highly confidential internal data outside. Through these enhanced AI capabilities, we provide even stronger support for the 'tedious document tasks' occurring daily on manufacturing and quality assurance frontlines, backing the dual achievement of operational efficiency and quality improvement.
## ■ 'Tedious Confirmation Work' Plaguing the Frontlines
In the operation of documents such as specifications, regular reports, and manuals, personnel spend a vast amount of time on confirmation work.
- Visually searching for and checking changed areas in specifications spanning dozens of pages.
- Comparing multiple files to check for inconsistencies with past versions or related documents.
- Losing track of the latest version after editing by multiple people, leading to missed corrections or reversions.
- Meticulously checking for notation variations or violations of internal rules.
crossnote supports these confirmation tasks—which previously relied on visual inspection—with AI agents, realizing a reduced burden on personnel and improved confirmation quality.
## ■ Leveraging AI While Protecting Confidential Data
Many companies feel uneasy about letting general-purpose AI read specifications and reports containing confidential information. crossnote supports configurations that can be safely used within customers' dedicated on-premise or closed network environments.
In this update, we have newly added support for Anthropic's 'Claude'. Claude is a powerful AI on par with ChatGPT and Gemini, drawing attention as one of the most dynamic AIs today. By setting an API key, various AI tasks using Claude can be executed on crossnote.
Furthermore, in addition to ChatGPT, Gemini, Claude, and local LLMs, crossnote also supports Sakura Internet's 'Sakura's AI Engine', making it possible to utilize open-source models in closed configurations.
## ■ Main Points Enhanced by the Update
The following features have been added or enhanced in this update:
### AI Support Ranging from Word/Excel to PDF
Utilizing ChatGPT's Code Interpreter and Claude's Analysis tool, we now support revision assistance for Word documents and Excel files. Furthermore, it supports AI reviews of PDF files, enabling reviews that consider non-textual information as well.
### Advancement of the AI Review Function
By running AI reviews on an agent basis, it can now load perspectives tailored to the review target from related files, enabling more flexible and practical reviews. It also assists with reviews based on rules and guidelines, consistency checks, and the presentation of proposed 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 upon saving, opening a file, or just before committing, supporting the efficiency of routinely repeated confirmation work.
### Improved Operability of AI Utilization
A Viewer that displays AI processing results in an easy-to-read format and an AI Console that centrally manages AI-related history are now available, improving the operability of AI utilization.
