Quillio vs Perplexity
Perplexity is a general-purpose AI search engine that does something genuinely useful — it answers questions with links to sources. It is not a legal AI. Its citations are web links, not legal authorities; its training is general; and its infrastructure is US-hosted. For legal work, Quillio is the right tool: weekly-updated AU/NZ legal training, citations to verifiable legal authority, AU data sovereignty, and the controls a regulated profession requires.
Perplexity is a general AI search engine that cites web sources. Quillio is an AU/NZ-trained legal AI with citations to verifiable legal authorities, AU data sovereignty, and the controls a regulated profession requires.
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 across all states, territories, and federal jurisdictions. Every research output includes source citations linking back to verifiable AU/NZ legal authorities. Quillio holds SOC 2 Type II and ISO 27001 certifications with full Australian data sovereignty.
Perplexity is a US-based AI search engine launched in 2022. It answers questions by synthesising content from the web and providing citations to the sources it used. Perplexity has become popular as a general research tool for students, journalists, analysts, and professionals who want sourced answers rather than a list of links. It is a general-purpose product and is not designed for legal practice.

Australian Law Coverage
Perplexity's citations are to web pages, not legal authorities. For a general research question that is often enough. For a legal research question, it is not — an AU lawyer needs to cite authority that has been identified, updated, and verified in context, not a web page that happens to mention the topic. Quillio is trained weekly on AU/NZ case law, legislation, and regulation, and every research output includes a citation to the underlying authority.
Data Sovereignty
Perplexity is US-hosted. Pasting client material into Perplexity raises the same confidentiality and data-residency questions as any US-hosted general AI product. Quillio is Australian-hosted by default, which aligns with AU privacy law and law society AI guidance for client matter.
Practice Management Integrations
Perplexity is a general search product and does not integrate with AU practice management systems. Quillio integrates with the AU PMS platforms AU firms use. Visit our integrations page for the full list.

Where Quillio Leads
- Quillio is grounded in a verified AU/NZ legal corpus with citations to the underlying legal authorities — not a list of web pages that happen to discuss the topic.
- Weekly training on AU/NZ legislation, case law, and regulation across every state and federal jurisdiction.
- Full Australian data sovereignty — client documents and queries processed and stored on AU soil.
- A complete audit trail of every query and output, designed for firm compliance and supervision obligations.
- Purpose-built AU PMS integrations so AI-assisted work happens inside the matter workflow.
Where Perplexity Has Strengths
- Perplexity has raised the bar for general AI search — the combination of synthesised answers and linked citations is genuinely useful for everyday information work.
- The product is accessible, well-priced for general research, and has a free tier that covers many casual use cases.
- Perplexity Enterprise has SOC 2 Type II and offers admin controls, making it a credible general-purpose research tool for business contexts.
- For non-legal research — learning a topic, checking a fact, summarising public material — Perplexity is a strong productivity tool.
- The web-grounded approach materially reduces the "confidently fabricated" failure mode common in ungrounded general AI.
Which Platform for Your Practice?
Real scenarios showing which platform suits different types of Australian legal practice.
You want to know whether Perplexity is good enough for legal research.
No — use Quillio for legal work. Perplexity's web citations are not legal authority and it is not trained on AU case law or legislation. Keep Perplexity for non-legal research if you like it.
You are drafting an internal AI policy and wondering where tools like Perplexity fit.
Most AU firm policies treat general AI like Perplexity as appropriate for non-confidential, non-substantive research only. A purpose-built legal AI (Quillio) is the right tool for client matter.
You want sourced answers on general business topics as well as legal work.
Quillio for the legal work; Perplexity can stay as a general research tool for non-legal, non-confidential topics. Do not paste client material into Perplexity.
Who Should Choose Perplexity
Perplexity is a fine general research tool — for non-legal topics, for news, for learning about an unfamiliar subject, or for anything where a web-sourced synthesised answer is the right answer. For lawyers, it can sit alongside a legal AI as a general productivity tool for non-confidential, non-substantive work.
Who Should Choose Quillio
For any work touching client matter, legal research, drafting that depends on accurate citations, or anything where being wrong has consequences, Quillio is the right tool. Purpose-built for AU/NZ law, citations grounded in verified authority, AU data sovereignty, audit trail for compliance, and a free trial to confirm fit.

Start Free TrialFrequently Asked Questions
Can I use Perplexity for legal research?
You can use it for general background reading on a legal topic, but it is not trained on AU/NZ legal sources and its citations are web pages rather than legal authorities. For substantive legal research, a purpose-built legal AI like Quillio is the right tool.
Does Perplexity cite legal authorities?
Perplexity cites whatever web pages it used to build its answer. That can include legal sources where they are openly available, but the citation quality and jurisdictional accuracy are not comparable to a legal AI grounded in a verified AU/NZ corpus.
Is Perplexity hosted in Australia?
No. Perplexity is US-hosted. Quillio is Australian-hosted by default, which matters when uploading client material.
How does pricing compare?
Perplexity has a free tier and a Pro plan around US$20/month for general research. Quillio publishes per-user legal pricing. The comparison is not like-for-like — they are different products.
Is Perplexity more accurate than ChatGPT?
For general questions, Perplexity's web-grounded approach reduces the fabrication risk common in ungrounded general AI. For legal questions specifically, neither is an adequate substitute for a purpose-built legal AI.
Should I use both Perplexity and Quillio?
Reasonable. Perplexity for general, non-confidential research; Quillio for legal work and anything touching client matter. Do not paste client material into Perplexity.
Can I try Quillio before committing?
Yes. Quillio offers a free trial with no credit card required. You can upload your own documents, run AU/NZ research queries, and test all features on your real matters before making any commitment.
