Quillio vs Alternatives to Casetext
Casetext was acquired by Thomson Reuters in 2023 for US$650 million and its flagship product, CoCounsel, now sits inside the TR stack alongside Westlaw. If you are evaluating Casetext alternatives from Australia, you are usually looking for an AU-built product that does not require buying into the TR ecosystem. Quillio is trained weekly on AU/NZ law, hosted on Australian infrastructure, and sold as a standalone product.
Casetext is now part of Thomson Reuters. Its AI product sits inside the US-first TR research stack. For AU/NZ firms, a purpose-built AU legal AI without a TR subscription attached is usually the cleaner answer.
Platform Overview
Purpose-Built for AU/NZ Quillio is an AI legal assistant purpose-built for Australian and New Zealand lawyers. It is trained weekly on AU/NZ legislation, case law, and regulatory updates. Features include document review, legal research with verified citations, automated chronology creation, drafting assistance, and voice-to-text dictation. Quillio is SOC 2 Type II and ISO 27001 certified with full Australian data sovereignty.
Casetext was a US legal research and AI company acquired by Thomson Reuters in 2023. Its flagship product, CoCounsel, was one of the first generative AI legal assistants and is now integrated into the TR product family alongside Westlaw and Practical Law. The Casetext brand continues but is effectively part of the TR stack, and the AI workflows are oriented to US legal practice.

Australian Law Coverage
Casetext's content library is US-focused via Westlaw. That is a genuine strength for US lawyers — and a genuine gap for AU/NZ practice. Quillio is trained weekly on AU/NZ primary sources. When an AU lawyer asks a research question, the answer is drawn from AU authorities with citations the lawyer can verify directly.
Data Sovereignty
Casetext runs on TR global infrastructure. AU data residency is typically negotiated at the contract level. Quillio is AU-hosted by default with SOC 2 Type II and ISO 27001, and data that never leaves Australian soil.
Practice Management Integrations
Casetext integrates inside the TR ecosystem. Quillio integrates with AU practice management systems AU firms use day-to-day. See our integrations page for the current list.
View all integrationsKey Differences That Matter
Where Quillio Leads
- Quillio is trained weekly on AU/NZ case law, legislation, and regulation. Casetext's content library is US-first via Westlaw.
- Full Australian data sovereignty: data is processed and stored entirely within Australia. Casetext runs on TR global infrastructure.
- Quillio is standalone — you do not need any TR subscription. For AU firms not on the TR stack, this removes a significant bundled cost.
- Published per-user pricing and a free trial with no credit card. Casetext / CoCounsel is sold through TR enterprise sales.
- AU practice management integrations. See our integrations page for the current list. Casetext integrations are US and TR-oriented.
Where Alternatives to Casetext Has Strengths
- Casetext pioneered generative AI in legal practice with CoCounsel, which was one of the first products to demonstrate what generative AI could do for lawyers — timeline creation, deposition prep, document analysis.
- The Thomson Reuters acquisition gave Casetext access to the Westlaw content library, one of the most comprehensive legal research databases globally, particularly strong on US case law.
- CoCounsel inside TR is a mature product with multiple generations of refinement and a large US customer base that has validated the workflows in real practice.
- For US firms already on the TR stack, the integrated Casetext / CoCounsel / Westlaw experience is genuinely strong and hard to replicate without moving the whole research footprint.
- Thomson Reuters has the editorial, security, and account management infrastructure of a century-old global legal publisher, which matters for large-firm procurement and governance.
Which Platform for Your Practice?
Real scenarios showing which platform suits different types of Australian legal practice.
You have read about CoCounsel in US legal media and wondered if it is the right tool for your AU practice.
Quillio. CoCounsel is US-focused and sits inside a TR stack designed for the US market. For AU practice, an AU-built product is a materially better fit.
Your team handles AU matters with a genuine US component. You are wondering whether to buy CoCounsel for the US work.
Quillio as the AU anchor. CoCounsel (with Westlaw) for US-specific research and drafting is a credible pairing if your US work volume justifies the TR cost.
The US parent uses CoCounsel. There is pressure to run the AU team on the same platform.
Quillio for AU work, CoCounsel for US work is a common arrangement. Uniformity across jurisdictions is not a compelling reason to run AU matters on a US-first product.
Who Should Choose Alternatives to Casetext
Casetext / CoCounsel remains the right answer for US firms already on Westlaw who want a mature generative AI layer on content they already license. For AU firms with material US cross-border work, Casetext can be a useful complement to an AU anchor product.
Who Should Choose Quillio
If you practise AU/NZ law and are looking for a Casetext alternative, Quillio is the most direct AU replacement. AU-trained, AU-hosted, AU PMS integrations, and priced transparently with a free trial — and no TR subscription required.
