AI and Law: Improving Legal Research

gavel

Legal research has always been a core skill for anyone working in law. Whether preparing a brief, writing an article, or trying to understand a ruling, it all starts with knowing where to find credible and relevant information.

Traditionally, that meant long hours of searching through databases, court rulings, and commentaries. Lately, this process has been changing fast.

AI is transforming how legal professionals approach research. It helps them find relevant statutes, cases, and academic insights faster, giving them more time to think critically. This article explores how AI is changing legal research, why human judgment still matters, and how to choose tools that help you work smarter.

Understanding Legal Research and the Role of AI

Legal research is finding and understanding the laws, court decisions, regulations, and expert commentary that support a legal argument or help answer a legal question. It’s not just about Googling a topic, it’s a structured way of gathering the right sources, figuring out what applies in a specific context (like a jurisdiction or type of case), and interpreting that information to back up a point of view. Whether writing a legal memo, preparing for court, or studying law, legal research ensures your arguments are grounded in real, credible authority - not just opinion.

Legal research is about supporting legal arguments with the proper evidence: case law, legislation, and scholarly interpretation. These sources are split into two categories: primary and secondary sources. Primary sources are the laws themselves - statutes, case law, and regulations. Secondary sources explain or analyze those laws, often written by legal scholars or experts.

Common challenges in traditional legal research involve dealing with clunky interfaces, vague filters, and mountains of irrelevant results. The process is often tedious, time-consuming, and overwhelming.

These are precisely the kinds of problems AI tools are now helping to solve, and legal professionals are starting to take advantage of them. An ABA Tech Survey found that AI adoption among law firms has nearly tripled from 2023 to 2024 (11% to 30%).

Even with advanced AI tools, legal research skills still matter. You still need to know whether a case is binding in your jurisdiction or whether a commentary reflects current law. Without that judgment, AI can only take you so far.

Legal research guides from institutions like Harvard Law School and Oxford Law recommend starting with a straightforward research question and a solid plan. That includes identifying the right types of sources, filtering them effectively, and documenting your process.

How AI Is Helping Transform Legal Research Today

AI and law are becoming increasingly intertwined. AI can't replace legal professionals, but it does help them become more effective. Law firms can save time and billable hours. Students can get better results faster. Solo practitioners can compete with firms that have bigger law research tools. AI helps level the playing field.

For example, AI for legal research can analyze large volumes of legal text, surface relevant precedents, and even summarize complex arguments. Whether you're a junior associate or a solo practitioner, that's a huge advantage. AI for legal research uses machine learning and natural language processing to identify relevant cases, extract key facts, and even point to applicable precedents that might otherwise be overlooked.

Tools like Westlaw and LexisNexis have started incorporating AI into their platforms, offering more intelligent search and automated insights. Meanwhile, tools like SciWeave bring a new dimension to legal research by answering your questions straight from academic sources - a tremendous asset when your case needs interdisciplinary support.

Other emerging AI platforms, like CoCounsel and Harvey AI enhance speed, reduce human error, and increase consistency by offering document review, deposition prep, and research summaries.

Key Features of AI Legal Research Tools

AI legal tools can:

  • Understand natural-language questions
  • Highlight key arguments and citations
  • Identify relevant legal texts more quickly
  • Recommend related material across cases or jurisdictions
  • Extract summaries from dense legal documents

Choosing the Right AI Tools for Legal Research

Older databases rely on exact matches and rigid filters. AI tools use contextual understanding to deliver better and faster results. Just like a human, they can for meaning, not keywords. SciWeave, for example, provides academic answers in seconds. That makes it worthwhile when you need strong, citable content outside traditional legal research tools.

If you consider bringing AI into your legal workflow, not just any tool will do. It needs to be accurate, reliable, and fit your research needs.

Ask yourself:

  • Does it save time?
  • Does it use trusted sources?
  • Are the citations transparent and traceable?
  • Does it easily integrate into the existing workflows?

AI Is Reshaping Legal Research - Don’t Get Left Behind

The need for AI in legal research is rapidly growing. AI can't replace expertise or legal reasoning but it speeds up the grunt work and opens new doors for finding insight. From case law to academic journals, AI helps legal professionals make better decisions faster.

Whether in law school, running a solo practice, or deep into litigation prep, integrating tools like SciWeave can save time, improve accuracy, and help you work more confidently.
