Legal tech has rapidly evolved in recent years, employing artificial intelligence (AI) to automate and streamline tasks such as legal research, document review, and contract analysis. A key to successful AI implementation in legal applications is prompt engineering, an innovative field that focuses on training AI models to respond effectively to specific user prompts.
Prompt engineers play a critical role in refining and optimising AI tools, tailoring them to better serve the specific needs of legal professionals. This blog post presents five practical case studies that showcase how properly trained prompt engineers can significantly enhance the efficiency and accuracy of legal AI tools.

Case Study 1: AI-Powered Legal Research
A multinational law firm faced challenges with the volume and complexity of legal research required for their cases. To solve this, they developed an AI tool capable of conducting extensive legal research in a fraction of the time.
Initially, the AI tool struggled with complex research prompts, often returning irrelevant or excessive information. Prompt engineers stepped in, refining the prompts to be more precise and context-specific. For example, they transformed the broad prompt "Find cases related to negligence" into a more detailed one: "Find Supreme Court cases from the last decade related to medical negligence."
The prompt engineering team's contributions led to a significant improvement in the AI tool's performance, enabling it to deliver more accurate and focused research results.
Case Study 2: AI Contract Analysis
A corporate law firm implemented an AI tool to review and analyse contracts, hoping to save time and reduce errors. However, the tool's initial output was subpar due to its generic approach to analysing contracts.
Recognising this, the firm's prompt engineers redesigned the prompts based on the specific type of contract being reviewed. They incorporated key elements related to different contract types, prompting the AI to highlight crucial clauses and potential risks.
With tailored prompts, the AI tool provided far more relevant summaries and risk analyses, significantly improving its value to the legal team.
Case Study 3: AI for Document Drafting
An innovative legal tech company introduced an AI-powered tool designed to assist with drafting various legal documents. The AI tool was initially limited, offering generic document drafts that lacked a personal touch.
Prompt engineers intervened, personalising the prompts based on users' specific needs and circumstances. For example, a user needing a will received a prompt like "Good morning, Alex. Let's work on your will today. Do you have a clear idea about the distribution of your assets?"
This personalisation led to more engaging user interactions and the creation of tailored legal documents, vastly improving user satisfaction with the tool.
Case Study 4: AI Legal Advisor
An online legal services platform aimed to offer preliminary legal advice through an AI legal advisor. However, the advice generated by the AI was often unfocused and missed crucial details.
The platform's prompt engineers revised the prompts to include specific directives, such as "Provide legal advice on the following property dispute issue, ensuring to consider local property laws and recent case laws."
The revised prompts led to more comprehensive and relevant advice, enhancing the platform's usefulness to its users and increasing client satisfaction.
Case Study 5: AI Assistant for Legal Education
A legal education platform incorporated an AI assistant to guide law students through their coursework. Initially, the AI assistant offered generic and often unhelpful responses due to its failure to account for the varying proficiency levels of students.
The prompt engineers personalised prompts based on students' performance data, tailoring the AI's responses to suit each student's level of understanding. This ensured the AI provided explanations, resources, and tips suited to each student's specific needs, resulting in a more effective and engaging learning tool.
These case studies underline the power of prompt engineering in optimising AI tools within the legal industry.
