An AI assistant for legal professionals that can analyze a legal query, search through vast databases of case law and statutes, and generate a summarized memorandum that outlines relevant precedents and legal arguments.
Legal research is essential but time-consuming. A lawyer preparing advice on a contract dispute may need to identify relevant legislation, find cases that interpreted similar clauses, check whether those cases have been followed or overturned, and summarise it all for a partner or client. Junior lawyers spend long hours in databases, and smaller firms without dedicated research staff often face tight deadlines with limited resources.
An AI legal research assistant speeds up the early stages. It takes a question in plain language, searches a licensed database of cases and legislation using semantic search, retrieves the most relevant passages, and drafts a memo that summarises the authorities with links to the source text. Retrieval-augmented generation grounds the answer in real documents, which reduces invented citations, but does not eliminate them. The lawyer must read the cited authorities, confirm they say what the memo claims and check their current status before relying on them.
The lawyer enters a research question with context such as jurisdiction, area of law and key facts, removing client-identifying details where the tool is not approved for them.
Semantic search runs across a licensed legal database, such as a Lexis+ AI or vLex service, retrieving relevant judgments, legislation and commentary.
The language model reads the retrieved passages and drafts a memo that outlines the legal issues, relevant authorities, how courts have applied them and open questions.
Every proposition in the memo links to the passage it relies on, so the lawyer can click through and read the original judgment or section.
The lawyer verifies citations and subsequent treatment, edits the analysis and saves the final memo to the matter file under normal supervision.
A lawyer needs to understand the precedents for a specific contract dispute. They ask the AI research assistant, which scans thousands of court documents and returns a memo summarizing the five most relevant cases, their outcomes, and key citations, saving hours of manual research.

Lawyers' professional conduct rules on competence, supervision and confidentiality apply to AI use, and several Australian courts and law societies have issued practice notes or guidance on generative AI, including restrictions on how it may be used in preparing court documents. Check the current requirements in each court you appear in. Client information is confidential and may be personal information under the Privacy Act 1988, so only enter it into tools your firm has assessed and approved. Choose platforms that clearly cover Australian jurisdictions, since tools built mainly for other countries may miss local authorities or cite foreign cases.
This solution requires careful evaluation of cost-benefit ratio. Consider implementation only after thorough analysis and risk assessment.
Only after you personally verify every authority and proposition. Courts have criticised practitioners who filed documents containing fabricated citations, and some Australian courts now require disclosure or restrict generative AI use in certain documents. Treat the tool as a research starting point, not a source you can cite.
Because this usually means adopting an existing platform rather than building one. The work is choosing a provider with strong Australian coverage, agreeing a firm policy, configuring accounts and training lawyers. Building a custom system over your own precedent bank is a larger, separate project.
Only if your firm has reviewed the provider's confidentiality terms, data storage location and whether inputs are used for training. Legal-specific platforms usually offer stronger commitments than consumer chatbots. Where in doubt, frame research questions generically without client names or identifying facts.
