Why Australian tax professionals choose Nylon over Lexis+ with Protégé
Lexis+ with Protégé is strong for broad legal research, with CaseBase and Halsbury’s. Nylon is built for cited tax answers from the primary sources, wherever you work.
Research inside your AI assistant
Adviser and Elite seats bring Nylon into Claude, ChatGPT and Microsoft Copilot, with every answer cited. LexisNexis’s public pages don’t describe a connector for Claude or ChatGPT.
Built on tax law
Nylon answers from legislation, ATO rulings and guidance, and case law, and links each citation to the source. LexisNexis writes its Australian pages for legal practices. Its tax practice area lists two publications, and ATO rulings aren’t described on its public pages.
No minimum term
Nylon is billed monthly and you can cancel anytime. LexisNexis’s terms say you can’t cancel during the minimum term in your order, and the subscription then renews for 12 months at a time.
Per-user prices, published
Nylon publishes a per-user price for Starter, Adviser and Elite. Lexis+ with Protégé is quote-only: LexisNexis scopes the price to your firm’s size and the content you need.
