Generative AI for Document Review: Revolutionizing the Legal Industry

11 Jun 2024

The legal industry is undergoing a significant transformation with the integration of Generative AI into the document review process. This advanced technology has the potential to revolutionize the way legal professionals approach their work, offering benefits such as increased efficiency, cost-effectiveness, and improved accuracy. This article will explore how lawyers can leverage Generative AI for document review and its impact on the legal profession.

Accelerating Large Document Review

Generative AI, powered by machine learning algorithms, can learn and adapt as it processes information, making it an invaluable tool for legal teams. One of the key advantages of using Generative AI for document review is the ability to review a large volume of documents at a fraction of the time and cost it would take for human review. This technology can review thousands of documents per hour, allowing legal professionals to focus on more complex and strategic tasks.

AI as the Lawyer’s Assistant

Furthermore, Generative AI can perform tasks that would be challenging for attorneys, such as providing narrative justifications for each decision. These justifications provide peace of mind for attorneys and contribute to creating comprehensive document summaries, custom queries, and case narratives. By leveraging Generative AI, legal professionals can accelerate the document review process, build thorough summaries, and create custom queries, ultimately saving time and money for both law firms and clients.

Lightning-Fast Document Summaries 

The functionality of Generative AI for document review has expanded significantly with the proliferation of AI technology and systems. It can now produce document summaries, search through complex file types, surface relevant documents, and more. Generative AI technology can also review various data types, including video calls and messages from communication platforms like Slack and Microsoft Teams. This versatility makes it a valuable asset for legal teams seeking to streamline their document review processes.

Generative AI Challenges

Integrating Generative AI into the legal industry is not without its challenges. One key challenge in adopting Generative AI for document review is the fear of missing critical information or of “hallucinations”.  In the litigation context, the specific sources for AI assertions are just a click away for easy verification, assuring accuracy.
