This paper presents the TAI Scan Tool, a Retrieval Augmented Generation (RAG)-based Trustworthy AI (TAI) self-assessment tool requiring minimal input. The current version supports legal TAI assessments focused on AI law compliance, utilizing a two-stage approach: a pre-review and an assessment phase. The assessment results provide insight into the risk level of AI systems under AI law, identify relevant provisions that facilitate compliance, and inform compliance obligations. Qualitative evaluations using use-case scenarios demonstrate that the tool accurately predicts risk levels while retrieving relevant provisions from three distinct semantic groups. Interpretation of the results demonstrates that the tool's inferences are based on comparisons with high-risk system settings, suggesting that such behaviors are associated with deployments that require careful consideration and are therefore frequently addressed in AI law.
