This document summarizes a study on requirement management tools for developing modern AI-based software. The study evaluated several open-source requirement management tools based on criteria such as extensibility, traceability, and GDPR compliance. While open-source tools provide flexibility, they often lack detailed documentation and the ability to handle regulatory requirements. Additionally, no single tool could adequately capture AI requirements from different stakeholder perspectives. The study concludes that developing trustworthy AI involves coordination among multiple groups, which current tools do not fully support.
