What to Look for When Choosing an AI Legal Assistant Tool?
- Verified Legal Databases: Ensure the tool pulls from authoritative legal sources (statutes and case law) rather than just the general internet to avoid “hallucinations” or false citations.

- ヒューマン・イン・ザ・ループ統合: The best tools are designed to assist, not replace. Choose software that makes it easy for you to review, edit, and approve every AI-generated suggestion.

- Native Workflow Support: Pick an assistant that lives where you work, such as a direct Microsoft Word add-in or a tool that integrates with your current practice management software.
- Explainable AI (XAI): Avoid “black box” tools. Your assistant should be able to explain its reasoning and provide direct links to the legal clauses it used for its analysis.
