Legal AI tools for small Australian law firms compared
When you compare legal AI tools for small Australian law firms, they fall into three groups: research and drafting tools, AI built into practice management software, and Outlook add-ins. The right one for your firm is the one that does the job costing you the most time, so work out that job first and then compare what each vendor says it does.

What kinds of legal AI tools can a small Australian firm buy?
Most tools fall into three groups, and the group matters more than the brand.
- Research and drafting tools come from the legal publishers. You ask a question or upload a document, and the tool works from legal content and your files.
- AI built into practice management software works from what is already saved in the matter, so it runs inside that system.
- Outlook add-ins sit in your email and start from the message in front of you. Microsoft's page on using add-ins in Outlook says an add-in might send data to its own service, but only to complete the task you asked for, and that most add-ins only have access to the email you are working in. Microsoft also says you are asked for consent the first time an add-in needs your data, so if one works across the whole inbox, check what it asks for.
Some tools cross over: Archie works in Outlook as well as in Smokeball.
How do the main legal AI tools compare?
This table uses only what each vendor says on its own page, as at 9 November 2026. If a page doesn't mention something, we have left it out, so a gap is not a no. It isn't every tool on the market, and none of the vendor pages linked in this table shows a price, so ask each vendor for a quote.
| Lexis+ with Protégé (LexisNexis). Research and drafting. | LexisNexis's small firm page says it is built for small firms. It says Lexis+ with Protégé speeds up legal research, generates first drafts, summarises and analyses your documents and gives linked citations, working with your firm's own knowledge and LexisNexis content. The page offers a free trial, without saying which product it covers. |
|---|---|
| CoCounsel (Thomson Reuters). Research and drafting. | Thomson Reuters' CoCounsel page lists legal research powered by Westlaw and Practical Law, knowledge search, document review and comparison, summaries, timelines, and drafting that draws on your repositories, Practical Law and playbooks. Its FAQ says CoCounsel Core customer prompts, content and output are currently stored and processed in Australia, and that your content and prompts are not used to train CoCounsel or third-party models. The page offers a demo. |
| Archie (Smokeball). Built into practice management. | Smokeball's Archie page says Archie works inside your matter to draft, review and answer questions. It says Archie in Outlook summarises email threads and drafts responses pulling from the matter, and that Archie sits in a Word sidebar. It also says Smokeball is certified to ISO 27001:2022 and has zero-data-retention agreements, and that your data is not shared with third parties for viewing, training or AI modelling. The page offers a demo. |
| Matter AI and LawY (LEAP). Built into practice management. | LEAP's legal AI page says Matter AI reads what is saved in the matter, including documents, emails, attachments, scanned PDFs and handwritten notes. It also lists matter summaries with a chronology, a Generator for letters, emails and forms, LawY for research and drafting, and AutoTime for logging billable hours. Its FAQ says these are included in every LEAP subscription, though elsewhere the page says LawY is included at no extra cost for select matter types, so ask LEAP what applies to your firm. The page offers a demo. |
| Manage AI and Clio Work (Clio). Built into practice management. | Clio's Australian AI page says Clio Manage can turn court documents into calendar events and tasks, generate draft invoices, match expenses to matters and draft letters and client updates, with Clio Work for document analysis and research. It says your data will never be used to train external models. Clio's help article on Manage AI says that, depending on where your firm is located, queries may be processed on servers outside your home jurisdiction, with resulting data stored in your region. It doesn't name countries, so ask Clio what applies in Australia. Clio's AI page offers a free trial and a demo. |
Which legal AI tool should a small firm look at first?
Start with the job that costs you the most time, not the longest feature list. A conveyancer with a full inbox in settlement week has a different problem from a two-partner litigation firm with an affidavit due Friday. One way to sort it:
- If research and first drafts of advice eat your week, look at the research and drafting group first.
- If you already run Smokeball, LEAP or Clio, find out what your own system does before you buy anything else. Your matters are already in it.
- If the inbox is the problem and your practice management system doesn't help with it, or you don't have one, look at Outlook add-ins. Our guide to the best Outlook add-ins for Australian law firms covers how to compare them.
If you are weighing up Microsoft's own option, see Microsoft Copilot in Outlook vs a legal AI add-in.
What should we ask a legal AI vendor about client data?
Some vendors answer these on their website and some don't. Where the page is silent, ask in writing and keep the reply on file.
- Where is the app and its database hosted?
- Where is the AI processing done, and is anything kept there?
- Is our client correspondence, or any of our documents, used to train AI models?
- Who at the vendor can see our data?
- What happens to our data if we stop using the tool?
If you use AI on documents filed in court, see our court AI rules tracker.
How to choose a legal AI tool for a small firm: a checklist
- Write down the three jobs that take most of your week.
- Check what your practice management system already includes, and on which plan.
- Shortlist one tool per job. Two tools that do the same job cost you twice.
- Check where each tool runs: Outlook, Word, or its own site.
- Check that a person approves anything before it is sent, filed or billed.
- Check the tool shows where its answers came from, so you can verify them.
- Get the data answers above in writing.
- Trial it for a week on real work, with one person, before you roll it out.
- Add up the monthly cost per practitioner for everything you plan to run.
Where does AI Legal Toolbox fit?
AI Legal Toolbox is in the Outlook add-in group. Its AI paralegal, Nova, triages the inbox, drafts replies into your drafts folder (it has no send function), reviews contracts and documents, and with Smokeball files emails and records time after you confirm. It works without a practice management system, minus filing and time recording. It is hosted in Sydney, with AI text processing by OpenAI in the United States, not retained there. It starts with a 7 day free trial (card needed, nothing charged until day 8), then $149 AUD per practitioner per month including GST. See the facts page.

Questions practitioners ask
What is the best legal AI tool for a small Australian law firm?
There isn't one answer. It depends on whether your biggest time cost is research, matter work or email, and on which practice management system you already run. Check what your own system includes before you buy anything else.
Do I need a practice management system to use legal AI?
Not for every tool. AI in Smokeball, LEAP or Clio Manage runs inside that system, so you need that system to use it. The LexisNexis and Thomson Reuters pages linked above don't list a practice management system as something you need.
How much do legal AI tools cost?
None of the other vendors' pages linked in this guide shows a price, so ask each one for a quote. LEAP's FAQ says its AI features are included in every LEAP subscription, though the page also says LawY is included at no extra cost for select matter types.
