The most important difference between general AI and legal AI is legal grounding.
A general AI assistant may be useful for brainstorming or writing. A specialized legal AI platform may connect its answers to legal databases, citations, case files, statutes, or other authoritative sources.

There is no single AI tool that is perfect for every American law firm. The right choice depends on practice area, firm size, budget, and the type of legal work being automated.

Its capabilities include:

How Lawyers Should Use AI Safely
AI should be treated as an assistant, not an attorney.
Before adopting a legal AI platform, a law firm should create a clear internal policy.
Check Confidentiality
Do not paste confidential client information into a tool without understanding how the platform handles, stores, and protects that information.
Verify Every Important Citation
AI-generated citations should be checked against the original source.
A confident-looking answer is not automatically a correct answer.
Review Court Filings Carefully
Never submit AI-generated legal arguments, facts, or citations without attorney review.
The ABA’s guidance emphasizes the lawyer’s responsibility for competence, confidentiality, and candor toward the tribunal when using generative AI.
Train Your Legal Team
Lawyers and staff should understand:
- What the AI tool can do
- What it cannot do
- How confidential information is handled
- How to verify citations
- When human review is mandatory
- How AI use should be documented
For additional guidance, U.S. lawyers can review the ABA’s Formal Opinion 512 on generative AI.
