Key takeaways from this article

  • Prioritize Practical ROI – Choose AI tools for legal professionals that directly reduce manual work, save time, and address real challenges in your firm’s workflow, rather than chasing flashy features you don’t need.
  • Demand Usability and Security – Select solutions that are intuitive for your team to adopt and meet stringent legal data security standards, including encryption, zero data retention, and compliance certifications.
  • Insist on Flexibility and Transparency – Your AI should adapt to your existing workflows, integrate with your current systems, and allow you to verify and edit outputs to ensure accuracy.
  • Seek Strong Vendor Partnership – Work with providers who offer responsive support, welcome feedback, and maintain a legal-specific development roadmap to keep pace with evolving needs.

Artificial intelligence is rapidly transforming the legal landscape, but with so many tools available (all touting life-changing capabilities, naturally), it’s easy to feel overwhelmed.  From document summarization to chat-based assistants and data extraction, the promises of AI are myriad. But how do you know which tools are right for your firm?

Whether you're tech-savvy or just beginning to explore what AI can do, here are six essential criteria every legal professional should look for in an AI tool.



Real-World Application and ROI of Legal AI Tools



Repeat after us: An AI tool is only valuable if it makes your job easier.

Just because it’s new and shiny and promises the world doesn’t mean you’ll benefit from using it. Furthermore, adopting it comes with an opportunity cost. Your time might be better spent evaluating other tools or, (ahem), focusing on your actual work.

This just means taking the time to evaluate AI tools thoroughly before making a decision.

For starters, look for features that reduce manual work. For example:

  • Automatic document generation
  • Immediate transcription of depositions or hearings
  • Quick extraction of names, dates, and key facts

These aren’t just flashy features; they save real time and increase your firm’s capacity for taking on new cases without adding headcount.

The best legal AI tools help you and your staff get more done without adding stress to your day by enabling you to:

  • Draft documents faster
  • Review case files more efficiently
  • Eliminate repetitive data entry
  • Capture insights without manually digging through paperwork

Ask yourself:

  • How many hours will this save my team each week?
  • What bottlenecks can this AI tool remove?

Example: A personal injury firm using AI to instantly summarize medical records may free up 5–10 hours per case, enabling them to take on more clients without hiring additional staff.

Key Takeaway: There is no point in adopting an AI tool that solves a problem you don’t have. Choose AI tools that directly save time, reduce manual work, and solve actual workflow challenges, not just ones with flashy features.



Ease of Use

You already have a law degree; you shouldn’t need a computer science degree to use AI.

A good legal AI tool should feel intuitive, not intimidating. If using the tool creates more confusion than clarity, it won’t get adopted by your team, full stop.

Look for:

  • Plain-English commands (natural language prompts)
  • Clean, intuitive interface
  • Simple onboarding process

Pro Tip: Avoid generative AI legal tools with a high learning curve, as they’re likely to discourage staff who are already hesitant about adopting new technologies.

The sooner your team sees success with the AI tool, the more likely they are to adopt it and benefit from it.

Example: AI embedded in your case management system (like NeosAI) can generate a client intake summary from notes in just a few clicks.

Key Takeaway: The best legal AI tools for lawyers are intuitive, require minimal training, and allow attorneys and staff to get results with natural language commands and simple clicks.





Data Security and Confidentiality

Your clients’ information is sacred. Your AI tool must treat it that way. You wouldn’t use a case management platform that didn’t promise top-level data security; why should an AI application be any different?

Legal professionals deal with highly sensitive and confidential data, and AI tools must adhere to strict privacy standards. At a minimum, ensure your AI provider offers secure cloud hosting (e.g., Microsoft Azure), encryption of data in transit and at rest, and a zero data retention policy—meaning any data passed through the AI is not stored or reused.

Your AI tool must:

  • Use secure cloud hosting (e.g., Microsoft Azure)
  • Encrypt data in transit and at rest
  • Follow a zero data retention policy

Warning: Avoid generic tools like ChatGPT or CoPilot for sensitive data. They aren’t designed for legal confidentiality.

Pro tip: Ask your vendor if they can share their security certifications or compliance standards (such as SOC 2 or HIPAA, depending on your practice area).

In an ideal world, your AI application should be embedded in your case management platform and follow the same security measures. This keeps your data protected, and as an added bonus, uses only information from your case files, improving output accuracy.

Key Takeaway: Only use AI tools with encryption, zero data retention, and legal-grade compliance certifications to safeguard sensitive client information.



Customization and Workflow Flexibility

Every legal practice has its own unique way of practicing law. Just like a good case management platform, your AI should adapt to you, not the other way around.

A solid AI tool will expedite your existing successful workflows, without forcing you into clunky workarounds. It should allow for easy integration into your existing case management systems (bonus points if the tool can work natively within your current software instead of forcing you to bounce between platforms!).

Look for:

  • Seamless integration with your case management software
  • Customizable templates and workflows
  • Ability to run directly within your existing tools

Avoid rigid tools that require a complete process overhaul just to implement AI. It’s time-consuming and often leads to push back from your staff.

Example: A family law firm integrates AI into its document drafting workflow, automatically populating agreements with case-specific details from its CMS.

Key Takeaway: Select AI tools that adapts to your existing processes, integrates with current systems, and eliminates the need for disruptive workflow changes.



Transparency and Trust

If you can’t verify the output, you can’t trust it. Many legal professionals have been tripped up by AI hallucinations because they didn’t verify the accuracy of the AI’s output.

Legal professionals must be able to audit and validate the results provided by AI, whether it’s a case summary, an extracted data point, or a draft document.

Your AI tool should:

  • Let you preview results before use
  • Highlight source references for each piece of information
  • Allow you to edit outputs before finalizing

Another benefit of AI embedded in your case management platform is the ability to easily verify results (as long as the tool offers this capability).

Key Takeaway: Always verify AI outputs. Choose tools that let you preview, source-check, and edit results before using them in legal work.



Vendor Support and Responsiveness

The best AI tools come from companies that listen to customer feedback, evolve to ever-changing legal workflows, and provide timely support. Both AI technology and the legal field are constantly changing; your technology should keep up.

Ask potential vendors:

  • Do you have a legal-specific roadmap?
  • Can customers submit feature requests?
  • What’s your average response time for support?

Your firm deserves more than just a software license! You need a collaborative partner that’s invested in your long-term success.

Key Takeaway: Work with AI vendors who provide responsive support, welcome feedback, and have a legal-specific development roadmap to keep up with evolving needs.



Don’t Just Adopt AI for the Sake of AI—Adopt the Right AI



Artificial intelligence has the potential to dramatically improve how legal professionals work if the tool(s) fit your evaluation criteria. Before you commit to any platform, take the time to evaluate how it performs across these six areas: usability, security, practicality, flexibility, transparency, and support.

By choosing wisely, you’ll not only avoid costly missteps—you’ll empower your team to supercharge their productivity, lower their stress, and work each case with greater confidence.

Key Takeaway: By focusing on usability, security, ROI, flexibility, transparency, and support, your firm can choose an AI solution that boosts productivity without compromising quality or compliance.
