This page compares Lex with Harvey, CoCounsel and Lexis+ AI on price, sources and data location. Lex facts come from saabai.ai. The other facts are quoted from each company's public pages, checked on 25 October 2026.
It is not a ranking. Where a public page does not state a price or a source list, this page says so.
Lex is Saabai's AI legal assistant for research and drafting. Lawyers use it on the Lex page.
The chat demo on that page, and on the law firm chatbot page, is a separate website chatbot for a fictional firm. It answers visitors. It does not search legislation or draft documents.
The Firm plan is $299 a month (AUD, GST not applicable) for 3 lawyer seats, unlimited research and 20 documents a month.
Enterprise is custom. There is no lock-in, and you can cancel any time. Source: the Lex pricing section.
Lex searches public Australian government sources: ATO rulings and interpretive decisions, the Federal Register of Legislation, whether an Act is in force, ASIC and the Fair Work Commission.
Lex does not currently search case law. Check case law yourself before you advise a client.
The Lex page does not state where data is hosted. This page does not add a location.
What the page does say is that names, business names, phone numbers, emails and ABNs or ACNs are swapped for placeholders before anything is sent to a model.
Harvey's homepage describes an AI platform for law firms and in-house legal teams, including agents, a document vault and contract tools.
The homepage does not list a price. On 25 October 2026, harvey.ai/pricing returned a 404, so no Harvey price is shown here.
The Harvey homepage and the Harvey security page do not name the legal databases Harvey searches. This page does not guess.
Harvey's security page says the cloud environment is hosted in Microsoft Azure, and that customers who need data localisation can use processing in the EU and Switzerland or Australia.
The same page also says customers can keep data in-region in the EU or Switzerland, the US, or Australia. Harvey's security addendum says customer data is stored in the region on the current order form.
Thomson Reuters Australia describes CoCounsel Legal as research, drafting and analysis grounded in Practical Law, Westlaw and the organisation's own knowledge.
The Australian CoCounsel pages checked on 25 October 2026 do not show a dollar price.
The US CoCounsel Legal pricing page shows a total only after you enter sector, number of attorneys, jurisdiction and plan length. It offers 1-year, 2-year and 3-year plans, and says online prices are for new customers. No dollar figure from that form is copied here.
The CoCounsel Legal Australia page says it draws on Practical Law guidance, Westlaw authority, and the organisation's documents.
That is Thomson Reuters' description of its own product. This page does not restate their marketing slogans.
The CoCounsel Australia page says data is hosted and processed in Australia. Its FAQ says CoCounsel Core customer prompts, content and output are stored and processed in Australia.
That FAQ names CoCounsel Core. The CoCounsel Legal Australia page checked on 25 October 2026 does not itself name a hosting country.
LexisNexis Australia's press release of 18 March 2025, published 20 March 2025, describes Lexis+ AI as conversational search, summarisation, drafting and document upload, with results backed by citable sources.
That press release and the April 2025 Australia customer terms do not state a dollar price.
On 25 October 2026 the Lexis+ with Protégé page and the Australia products page returned HTTP 403, so they are not cited.
The press release says results are backed by verifiable, citable authority and describes the content as Australian legal content. It does not list database names in the passage used here.
The April 2025 terms say access to the Lexis+ AI Service requires a current subscription to Lexis+ and the associated minimum content package.
The press release says sensitive information is stored and processed in Australia, using Amazon Web Services and Microsoft Azure.
Clause 3.9 of the April 2025 terms says the primary hosting location for the Lexis+ AI Service is Australia. If a failover moves processing outside Australia, the terms say upload is disabled during that failover.
Each link is the public page the row above relies on. Competitor wording is theirs, not a Saabai claim about their product.

Public Australian government sources: ATO rulings and interpretive decisions, the Federal Register of Legislation (including whether an Act is in force), ASIC and the Fair Work Commission. Lex does not currently search case law.
The Lex page does not state a hosting location. This comparison does not add one.
No. Lex is the AI legal assistant for research and drafting, and the law firm website chatbot is a separate demo that answers visitors and does not search legislation or draft documents.
