Quillio vs Best AI for Due Diligence in Australia (2026)
Due diligence is one of the most time-intensive legal workflows — and one where AI delivers clear, measurable ROI. But the tool you choose depends on the type and scale of DD you run. For enterprise-scale contract analytics across thousands of documents, platforms like Luminance and Kira are purpose-built. For the broader DD workflow — including AU regulatory research, jurisdiction-specific risk flagging, chronology building, and document review at typical AU mid-market volumes — Quillio is the stronger all-round fit, with the added advantages of AU data sovereignty and weekly AU/NZ law training.
Due diligence is document-intensive, time-pressured, and demands accuracy. The right AI tool should accelerate review without introducing risk. For Australian transactions, it must also understand AU regulatory requirements and maintain data sovereignty over deal documents.
Platform Overview
Purpose-Built for AU/NZ Quillio is an AI legal assistant purpose-built for Australian and New Zealand lawyers. Its document review capability handles contracts, regulatory documents, corporate records, and correspondence. Combined with weekly-updated AU/NZ legal research, automated chronology creation, and AU data sovereignty, it provides an end-to-end DD support tool for AU mid-market and larger transactions. SOC 2 Type II and ISO 27001 certified.
The AI landscape for due diligence includes dedicated DD platforms (Luminance, Kira Systems), general-purpose AI (ChatGPT, Copilot), US-focused legal AI (Harvey, CoCounsel), and research platforms with AI (Westlaw AI, Lexis+ AI). The market segments by scale: enterprise DD platforms handle thousands of contracts per deal; general legal AI handles the broader research and advisory layer around due diligence.

Australian Law Coverage
Due diligence on Australian transactions requires understanding AU-specific regulatory requirements — Corporations Act compliance, FIRB approval thresholds, ACL obligations, sector-specific licensing, and state-based regulatory frameworks. A DD platform that only classifies contract clauses (like Luminance or Kira) does not provide this regulatory research layer. Quillio combines document review with AU-specific legal research, so risk flagging is grounded in current authority.
Data Sovereignty
DD documents are among the most commercially sensitive materials a law firm handles — target company financials, intellectual property schedules, customer contracts, and strategic plans. Australian data sovereignty is non-negotiable for many AU transactions, particularly where target companies have government contracts or sensitive customer data.
Practice Management Integrations
DD workflows in AU firms run through practice management systems and document management. Quillio integrates with AU PMS platforms so document review and research happen inside the existing workflow. See the integrations page for the current list.

Where Quillio Leads
- AU regulatory research integrated into the DD workflow — Corporations Act, FIRB, ACL, sector-specific regulation — so risk flagging is grounded in current AU law rather than generic contract analytics.
- Verified citations on every research output — when your DD report flags a regulatory risk, the citation to the underlying AU authority is included.
- Full Australian data sovereignty — deal documents, target company records, and commercially sensitive materials are processed and stored on Australian infrastructure.
- Automated chronology creation from DD documents — particularly useful for building corporate history timelines and identifying gaps in the document set.
- Per-user pricing with a free trial means mid-market firms can access DD AI without the enterprise procurement that Luminance and Kira typically require.
Where Best AI for Due Diligence in Australia (2026) Has Strengths
- Luminance is one of the most established DD platforms in the world, with deep clause extraction, anomaly detection, and pattern recognition across very large document sets — purpose-built for enterprise M&A.
- Kira Systems (now Litera) has refined its contract review clause library over more than a decade of large-firm deployments, giving it depth in specific clause identification.
- Harvey and CoCounsel offer strong US/UK DD research capabilities for cross-border transactions governed by US or UK law.
- For mega-deals (thousands of contracts, multi-jurisdictional), enterprise DD platforms offer workflow features — team assignment, progress tracking, reporting dashboards — that a general legal AI does not replicate.
Which Platform for Your Practice?
Real scenarios showing which platform suits different types of Australian legal practice.
You run buy-side DD on transactions with 50-500 documents. You need to review contracts, flag regulatory risks, and draft the DD report.
Quillio. Document review, AU regulatory research, FIRB analysis, and DD report drafting — all with AU data sovereignty. At mid-market volumes, Quillio handles the full workflow without needing a separate enterprise DD platform.
You have 3,000 target contracts plus regulatory research across multiple AU jurisdictions. You need both volume contract review and deep regulatory analysis.
Run Luminance or Kira for the high-volume contract analytics, and Quillio for the AU regulatory research, FIRB analysis, and DD report drafting. The combination covers both the volume and the substance.
You are running preliminary DD on a potential acquisition. You need to review key contracts and research regulatory implications before engaging external counsel.
Quillio. Per-user pricing and a free trial let you start immediately without enterprise procurement. Upload key contracts, research regulatory questions, and form a preliminary view before briefing external counsel.
Who Should Choose Best AI for Due Diligence in Australia (2026)
Firms running mega-deal DD (thousands of contracts per transaction) should evaluate Luminance or Kira for the volume contract analytics workstream. For US/UK cross-border DD research, Harvey or CoCounsel offer deeper jurisdiction-specific coverage for those markets.
Who Should Choose Quillio
Australian firms running mid-market DD — and any firm that needs AU regulatory research, FIRB analysis, jurisdiction-specific risk flagging, or DD report drafting grounded in AU law — should choose Quillio. For larger deals, Quillio can sit alongside a volume DD platform.

What is the best AI for legal due diligence in Australia?
It depends on scale. For enterprise-scale DD (thousands of contracts), Luminance and Kira are purpose-built. For mid-market DD and the regulatory research layer around any deal, Quillio is the stronger fit because it combines document review with AU-specific legal research and data sovereignty.
Is Luminance better than Quillio for DD?
For very high-volume contract analytics (clause extraction across thousands of documents), Luminance is purpose-built for that task. For AU regulatory research, FIRB analysis, and DD report drafting grounded in AU law, Quillio is stronger. Many firms use both.
Does Quillio handle FIRB research?
Yes. Quillio is trained on FIRB legislation, thresholds, and guidance, including recent changes to foreign investment review requirements for different transaction types and sectors.
Is AI safe for deal documents?
With Quillio, yes. Full Australian data sovereignty means target company documents and deal materials are processed and stored on Australian infrastructure. Do not upload sensitive DD materials to US-hosted tools without assessing data residency implications.
Can AI draft DD reports?
Yes. Quillio can assist with drafting DD report sections grounded in AU regulatory analysis, with citations to relevant legislation and case law. All AI-assisted drafting should be reviewed by the responsible partner.
Can I try Quillio before committing?
Yes. Quillio offers a free trial with no credit card required. Upload sample DD documents, run regulatory research queries, and test the tool on real transaction materials.
