Will AI Replace Lawyers? How AI Tools Empower Legal Teams

“Most lawyers I’ve talked to say that if you ask ChatGPT, let alone a more sophisticated version, to write a memo about a legal question, you will get something approximately as good as what a first-year law firm associate would produce.”

- Professor David Wilkins, Director of the Center on the Legal Profession at Harvard Law School

Legal professionals at enterprises often spend hours reviewing documents and analyzing case laws. This process can lead to significant delays and errors due to the sheer volume and complexity of information. With recent technological advancements and the AI boom, a popular question is: Is there AI for lawyers? The simple answer is yes. AI is changing the legal sector by making legal tasks faster, improving decisions, and helping lawyers build better client relationships. 

Specifically, AI lawyer tools are designed to automate key legal tasks like document review, contract analysis, and compliance monitoring. By handling these routine responsibilities, AI is helping firms improve efficiency, reduce human errors, and streamline legal workflows. The need for efficiency, cost savings, and better risk management fuels this transition from traditional manual processes to AI-driven legal tools. A recent Gartner study predicts that legal sector investments in technology will triple by 2025, growing from 3.9% to 12% as firms increasingly integrate AI-powered solutions. 

Reflecting on this momentum, Cecilia Ziniti, CEO and co-founder of GC AI, emphasizes how AI tools for lawyers are reshaping the legal profession: “The pinnacle of AI application in the next five to 10 years is going to be empowering lawyers.” She envisions an "AI lawyer copilot" that assists attorneys in managing routine tasks and enhancing efficiency. Rather than replacing lawyers, AI enables them to concentrate on critical thinking, client strategy, and high-stakes cases.

In this article, we’ll discuss how AI lawyer tools are helping legal professionals overcome key challenges in enterprises. We’ll also explore real-world case studies and provide practical insights for adopting AI in enterprise legal departments.

Addressing Errors and Regulatory Challenges with AI Lawyers

‍

Reviewing legal documents like contracts, compliance records, and case files manually can take up much time and involve the risk of mistakes due to oversight. However, we see both paid and free AI lawyer tools help solve this issue by automating document processing to make reviews faster and more accurate. Studies show that 95% of legal professionals using AI reporting tools save significant time each week.

In particular, generative AI and large language models (LLMs) improve legal drafting by simplifying contract analysis and accelerating case research. For example, LLM-powered tools, such as ChatGPT for lawyers, can quickly summarize legal precedents, extract critical clauses, and generate accurate legal documents, reducing the need for manual reviews. Also, AI chatbots and predictive analytics also contribute to a more efficient legal process by offering real-time insights, pinpointing potential risks, and automating compliance tracking, which simplify and expedite legal workflows.

Based on the range of legal tasks AI lawyers can support enterprises with, many now wonder: will AI replace lawyers? However, the rise of AI in law isn't about replacing lawyers; it’s about helping them work smarter. 

“Lawyers who use AI are going to replace lawyers who don’t, rather than AI replacing all lawyers.”

— James Clough, CTO of Robin AI

AI is becoming a key tool for those looking to stay competitive and boost efficiency. Many businesses already use AI lawyer tools to work faster and more accurately. Next, we’ll walk through real-world case studies that illustrate how companies effectively leverage AI tools for lawyers to reinvent legal work.

How a Global Law Firm Used AI to Cut Contract Review Time by 80%

‍

Dentons, a renowned global law firm, encountered a substantial challenge in its Dubai office when tasked with a large-scale document review project. Initially, the team anticipated reviewing only 200 to 300 documents. However, the scope rapidly expanded to over 180,000 documents that needed to be reviewed in just two weeks - a volume that rendered manual review nearly impossible. In search of a more efficient solution, Dentons turned to AI lawyer tools.

They used Luminance’s AI-powered document review platform, transforming how the team managed this immense workload. Luminance’s advanced data visualization allowed the team to grasp the entire dataset at a glance. At the same time, its core AI module, combining supervised and unsupervised machine learning algorithms, quickly identified anomalies and highlighted critical information. The platform’s task management and workflow tools ensured that documents were auto-assigned, tracked in real-time, and reviewed collaboratively across Dentons' Dubai and UK offices, eliminating duplication of effort.

Key outcomes from this innovative approach included an 80% reduction in review time, cutting a process that would have taken 60 working days to just two weeks, and a comprehensive review of over 180,000 documents. 

Also, Luminance’s language-agnostic and jurisdiction-agnostic capabilities enabled the seamless processing of documents in both English and Arabic. This solution met their tight deadline and redefined document review at Dentons.

How an AI  Made Research Faster at Leading Global Firm A&O Shearman

‍

Similarly, A&O Shearman, a multinational law firm with 4,000 lawyers across 43 jurisdictions, recognized that legal research and drafting took valuable attorney time. Routine tasks like analyzing legal precedents, summarization, and clause identification reduced the time available for high-value client work. To improve efficiency, the firm sought an AI-driven solution to streamline these processes while maintaining accuracy and control.

In December 2022, A&O Shearman started using Harvey AI, a customized large language model for legal research. This AI lawyer quickly analyzed vast legal datasets, summarized key insights, and suggested relevant clauses to enhance accuracy. A&O Shearman attorneys could access information faster by integrating Harvey AI into research workflows. Another key factor of this integration is that, while reducing manual effort, it also ensures that legal professionals remain in control of the final output.

Harvey AI helped 4,000 A&O Shearman lawyers save 2–3 hours per week on research and drafting tasks, making it possible for them to focus more on strategic client work. It also improved the precision of legal documents with AI-assisted clause suggestions, leading to better outcomes without losing oversight.

An AI Lawyer Helped Win an E-Discovery Motion

‍

Another compelling example highlights how AI lawyer tools make a difference in high-stakes litigation. A large plaintiffs firm faced a case against several commercial airlines that required reviewing an enormous volume of legal documents. The defendants used a TAR 1.0 system (Technology Assisted Review) to process 3.5 million records for e-discovery, estimating that 85% were relevant with a 58% precision rate and assuming a one-to-one ratio of relevant to non-relevant documents. However, these assumptions fell short, as the system generated far too many unnecessary files - resulting in a lengthy, costly, and inefficient review process.

The plaintiffs’ legal team turned to Casepoint’s AI-powered analytics (TAR 2.0) to solve this issue. This AI lawyer tool quickly identified errors in the initial review. It found that 97% of the relevant documents were included, but the precision rate was only 16.7%. There were three unnecessary documents for every valid document, leading to significant overproduction and wasted time.

‍

Armed with this evidence, the plaintiffs motioned to extend the review period. They leveraged AI lawyer tools to demonstrate that the defendants’ TAR estimates were off the mark. The defense eventually acknowledged the error, and the court granted the extension. AI accelerated the review process by 83%, slashing manual effort and paving the way for a faster, more accurate, and fairer litigation process.

Beyond the Buzz: What Law Firms Need to Know About AI Lawyer Tools

As we’ve seen in the previously discussed case studies, enterprise law firms and legal departments are increasingly adopting AI lawyer tools to boost efficiency. Recent insights from Gartner indicate that large language models (LLMs) could boost legal department productivity by 10% to 20% over the next two to five years, surpassing earlier technological advances. Many legal professionals are already using AI-driven tools like ChatGPT for lawyers.

However, not every AI solution fits every firm's needs. Enterprises must select AI tools that align with their specific workflows, whether for contract review, compliance tracking, or legal research, to achieve optimal results.

Additionally, successful AI adoption requires proper training for legal teams. AI lawyer tools are only effective if professionals understand how to use them efficiently. Without training, AI can create confusion instead of improving productivity. At the same time, AI tools should aim to support human expertise, not hinder it.

“We need to look at the outputs of Gen AI with a critical eye and apply our human judgment to evaluate whether we trust them. In many cases, the outputs are spot on and can advance our thinking. As long as we keep humans in the loop, we can do a lot of good with Gen AI.”

— Ben Ellencweig, Leader of QuantumBlack

Aside from these aspects, implementing AI solutions comes with challenges, such as data privacy risks, security concerns, and integration with existing systems. It is ideal for firms to invest in AI solutions with strong encryption and ensure compliance with legal data protection standards. Clear AI governance policies and staff training help firms use AI responsibly while maintaining security and compliance.

AI Tools for Lawyers Are Getting Smarter

As technology advances, legal operations are poised for a significant transformation. With the legal industry projected to invest over $46 billion in AI by 2030, the shift toward automation is gaining momentum. Open-source large language models and free AI lawyer tools are democratizing access to sophisticated legal research, drafting, and case analysis.

On top of this, legal AI tools for enterprises are evolving from simple automation to advanced agentic systems that function autonomously within established legal frameworks. These intelligent tools analyze vast datasets, predict outcomes, and drive faster, more informed decision-making - empowering firms to strengthen risk management, scale regulatory compliance, and enhance strategic insights.

Integrating AI lawyers into enterprise legal systems can help optimize workflows and reduce costs, positioning firms to extend their expertise across global operations with unparalleled precision and consistency. This marks a turning point in legal innovation, where AI and human expertise can work together to shape the future of legal practice.
