Complete your due diligence faster, with higher confidence
Highlights
- AI is rapidly transforming the legal profession, with 80% of professionals anticipating a significant impact and over half already realizing ROI through enhanced efficiency, productivity, and error reduction in tasks like legal research.
- To counter the risk of AI 'hallucinations,' legal platforms must be built on trusted content; Deep Research in Westlaw Advantage provides this by combining advanced AI with Westlaw's authoritative library of cases, statutes, and secondary sources to deliver accurate, reliable answers.
- Beyond litigation, AI-powered tools like Deep Research benefit transactional lawyers by creating custom research plans for due diligence and commercial negotiations, enabling them to develop robust legal strategies and move from research to action with greater confidence.
There’s no doubt artificial intelligence (AI) is reshaping our world. In the 2025 Future of Professionals report from Thomson Reuters, eight out of 10 respondents said they believe AI will have a transformational or high impact on their work within the next five years. With its ability to analyze large data sets, synthesize data into actionable insights, and improve decision-making, AI is reshaping how legal professionals approach their work.
AI is helping lawyers enhance their workflows, notably through using AI for legal research. AI tools for legal research save time and increase efficiency, turning tedious processes into streamlined, effective work. These tools can process and analyze vast amounts of legal texts much faster than humans can, giving legal professionals more capacity to focus on work uniquely suited to their experience and expertise — something AI can’t do on its own.
Many organizations, including those in the legal sector, are realizing returns on their AI investments. Just over half the professionals surveyed for the 2025 Future of Professionals report said they were already seeing a return on investment (ROI) directly or indirectly tied to AI. Often this ROI takes the form of improved efficiency and productivity, increased responsiveness, and a reduction in errors. It is evident that such improvements are driving increased adoption of AI in the workplace.

Deep Research for transactional lawyers
Getting there with confidence
Embracing the idea of using AI for legal research is one thing. Trusting the process is another. By now, many are familiar with the concept of hallucinations, phenomenon where AI generates responses based on patterns rather than verified facts, leading to potentially incorrect or misleading outcomes. To fully leverage the ground-breaking benefits of AI, legal organizations must ensure their legal research platforms are built on trusted content.
Deep Research in Westlaw Advantage seamlessly blends advanced technology with the legal industry’s most trusted content. Westlaw has used AI to provide editor-created answers for over a decade and now uses Deep Research to craft tailored responses to user queries across jurisdictions in real time.
Deep Research in Westlaw Advantage doesn’t just generate text based on the query. Rather, it searches through trusted content to find the most relevant cases, statutes, regulations, secondary sources, and administrative content. This allows the tool to think like an expert researcher and build a custom multi-step research plan to help you move from research to strategy faster. This ensures that responses are based on the most pertinent information, providing accurate and reliable answers.
Deep Research for transactional lawyers
When most people think of legal research, they think litigation. But due diligence, the transactional lawyer’s stock in trade, can reap the benefits of legal research powered by AI as well. Understanding market trends, negotiating commercial arrangements, and helping clients figure out how to best carry out their transactions are all foundational aspects of transactional work. Each agreement requires not just a basic understanding of transactional legal principles, but also specific research tailored to the particular transaction.
