About Lexis+ AI
What is Lexis+ AI?
LexisNexis's generative AI legal assistant, which answers research questions, drafts documents and summarises material with linked citations to LexisNexis primary and secondary content. In Australia it includes the Protégé personalised assistant and Lexis Create+ for drafting in Microsoft Word. Lexis+ AI is an AI legal tool that assists with document review, contract analysis, legal research, drafting, and compliance monitoring.
Lexis+ AI launched commercially in Australia in 2024 and moved to local hosting in early 2025, so prompts and documents are stored and processed within Australia on AWS and Microsoft Azure. That helps firms meet client confidentiality duties under the solicitors' conduct rules and their Privacy Act 1988 obligations. Courts are setting their own rules too: the NSW Supreme Court's practice note on generative AI restricts its use in affidavits, witness statements and expert reports. Lawyers must verify every citation and remain responsible for the advice, whatever the tool says.
How Australian Businesses Use Lexis+ AI
Law firms and in-house legal teams use AI tools to review contracts faster, research case law, draft standard documents, check for compliance gaps, and answer internal policy questions — significantly reducing billable hours on routine legal work.

Since early 2025 LexisNexis has hosted Lexis+ AI for Australian customers locally, with storage and processing on AWS and Microsoft Azure in Australia. LexisNexis says data is encrypted in transit and at rest, access is audited, and prompts are not used to train public AI models.

Integrations & Compatibility
Lexis+ AI integrates with the tools and platforms your team already uses:
Getting Started with Lexis+ AI in Australia
Lexis+ AI is available directly at lexisnexis.com.au. Start with lower-risk document review tasks (NDAs, standard agreements) before using AI for complex contracts. Always have a qualified lawyer review AI-generated legal documents. Establish a clear policy on which tasks require human sign-off.
Outside help is most useful when the tool has to connect to existing systems, handle personal information, or be rolled out to a whole team. AI Lab Australia works with businesses across Sydney, Melbourne, Brisbane, Perth and Adelaide on that setup.

Frequently Asked Questions About Lexis+ AI
Is Lexis+ AI hosted in Australia?
Yes. LexisNexis introduced local hosting for Australian customers in 2025, so data and prompts are stored and processed in Australia using AWS and Microsoft Azure. This matters for firms whose clients or panel agreements require onshore handling of confidential information. Confirm with your account manager that your subscription is on the Australian instance.
What is LexisNexis Protégé in Australia?
Protégé is the personalised AI assistant LexisNexis made generally available in Australia in July 2025. It runs within Lexis+ AI and Lexis Create+ for Word, can carry out multi-step tasks towards a goal you set, and draws on both LexisNexis content and your own documents. Outputs still need lawyer review.
Can I rely on Lexis+ AI citations in court documents?
Treat them as a starting point. Linked citations make checking easier, but you must read the authority yourself before relying on it. Court practice notes, such as the NSW Supreme Court's note on generative AI, set extra limits on AI use in evidence, so check the rules of the court you are filing in.
