Plugin Overview:
The LLM Plugin is an extension for Astah SysML and Astah System Safety that integrates large language model (LLM) capabilities, enabling automated and intelligent documentation for SysML blocks’ properties.
This plugin allows you to generate comprehensive descriptions for each field of a selected block using AI-powered assistance, making model documentation faster and more efficient.

How to use

If you have manually documented the definition field, using this plugin will overwrite the existing content.
