Frequently Asked Questions {#faq}

What is the difference between agentic AI and traditional legal AI tools?

Traditional legal AI tools are reactive, responding to specific queries or performing single tasks like document review. Agentic AI is proactive and autonomous, capable of planning and executing complex, multi-step legal workflows with minimal human intervention. For example, while traditional AI might help you search for relevant cases, agentic AI can research the issue, analyze precedents, identify legal strategies, and draft a preliminary memo autonomously.

How much does it cost to implement agentic AI in a law firm?

Implementation costs vary significantly based on firm size and scope. Small firms might start with $5,000-$15,000 annually for basic agentic AI capabilities, while large firms could invest $100,000-$500,000+ for comprehensive implementations. However, most firms see ROI within 6-12 months through efficiency gains and cost reductions. Consider platforms like LegesGPT that offer scalable pricing models suitable for different firm sizes.

Is agentic AI secure enough for confidential legal work?

Yes, when properly implemented. Leading agentic AI platforms designed for legal practice include enterprise-grade security features such as end-to-end encryption, role-based access controls, and compliance with attorney-client privilege requirements. However, firms must carefully evaluate vendors' security capabilities and implement appropriate governance and oversight procedures.

Will agentic AI replace lawyers?

No, agentic AI is designed to augment and enhance legal practice, not replace attorneys. While AI agents can handle routine tasks and provide analytical support, lawyers remain essential for strategic thinking, client counseling, courtroom advocacy, and complex legal judgment. The most successful implementations involve AI-human collaboration, where each contributes their unique strengths.

What are the ethical considerations for using agentic AI in legal practice?

Key ethical considerations include maintaining professional responsibility for AI agent actions, ensuring client confidentiality and data security, addressing potential bias in AI decision-making, and providing appropriate disclosure to clients about AI use. Attorneys must maintain oversight of AI agent work and ensure compliance with professional conduct rules.

How do I choose the right agentic AI platform for my firm?

Evaluate platforms based on legal-specific capabilities, integration with existing systems, security and compliance features, vendor support quality, and total cost of ownership. Consider starting with a pilot program to test functionality and user adoption. Platforms like LegesGPT offer specialized legal knowledge bases and verified citations, making them particularly suitable for legal practice.

What training do attorneys need to work with agentic AI?

Attorneys need training on AI capabilities and limitations, best practices for AI-human collaboration, ethical considerations, and specific platform functionality. Most successful implementations include comprehensive training programs covering both technical skills and strategic thinking about AI integration into legal workflows.

How can small law firms compete with large firms using agentic AI?

Agentic AI actually levels the playing field by giving small firms access to capabilities previously available only to large firms with extensive resources. Small firms can leverage AI agents to handle routine tasks, improve efficiency, and offer competitive pricing while maintaining high-quality service. Cloud-based AI platforms make enterprise-level capabilities accessible to firms of all sizes.

What are the biggest risks of implementing agentic AI?

Main risks include over-reliance on AI without proper oversight, data security breaches, potential bias in AI decision-making, integration challenges with existing systems, and resistance to change from staff. These risks can be mitigated through careful planning, comprehensive training, robust governance procedures, and gradual implementation with continuous monitoring.

How will agentic AI change legal billing and pricing models?

Agentic AI is likely to accelerate the shift from hourly billing to value-based pricing models. As AI agents increase efficiency and reduce time spent on routine tasks, firms will need to focus on the value delivered rather than hours worked. This may lead to more fixed-fee arrangements, subscription-based services, and outcome-based pricing models.
