Key Advantages

  • Broadest international jurisdiction coverage among major legal research platforms (100+ countries)
  • Meaningfully cheaper than Westlaw or Lexis for comparable research volume
  • Often available free through state bar association membership via Fastcase

Considerations

  • US editorial depth and citator features are still viewed as less mature than Westlaw's KeyCite
  • Jurisdiction coverage depth varies by country, strongest for the US, UK, EU, and Latin America
  • Not recommended by some reviewers as the sole research tool for high-stakes US litigation
