Pros & Cons

Lexis+ AI

  • Integrates directly with an existing Lexis+ research subscription for a unified workflow
  • Flat-rate bundling can offer meaningful savings for firms with predictable, regular AI usage
  • Backed by LexisNexis’s established legal research infrastructure and content
  • No published per-seat pricing — every quote requires a direct sales conversation
  • Transactional rates ($99/AI Ask, $250/AI Drafting) can accumulate substantially for unpredictable usage
  • Annual price increases of 3-7% are standard unless specifically negotiated at contract signing

ChatGPT

  • Largest user base and ecosystem of any AI assistant, with the most third-party integrations
  • Genuinely broad capability across writing, coding, research, and file analysis
  • Custom GPTs allow tailoring the assistant to specific repeated tasks
  • Frequent model updates keep it competitive on raw capability
  • Free tier has usage limits and access to a lower-tier model than paid plans
  • Can produce confident-sounding but incorrect information, especially without browsing enabled
  • Breadth can mean less depth than a tool purpose-built for one specific workflow
  • Data usage and training policies require attention for sensitive or regulated work
