- Accuracy Boost: Minimize human error with citation-verified outputs and hallucination-free responses.
- Scalability: From solos using free tiers to firms handling terabytes of e-discovery data.
- Ethical Compliance: Tools now prioritize data privacy (e.g., GDPR, ABA rules) with anonymization and no-training-on-user-data policies.
To implement effectively, start with a needs assessment: Identify pain points (e.g., research bottlenecks?), pilot 1-2 tools with free trials, and train your team via built-in tutorials. Always cross-verify AI outputs to uphold professional responsibility.
