Pros & Cons

Harvey AI

  • Established, well-known platform specifically built for legal AI use cases
  • LexisNexis integration option provides meaningful research capability expansion
  • Genuine enterprise-scale legal AI capability for large firms with substantial budgets
  • No published pricing — requires a demo-led sales process for a custom quote
  • Real per-seat costs ($1,200-$2,800+/month) run far higher than Harvey’s own ROI calculator estimate ($288-500/month)
  • Total first-year cost commonly runs 30-50% above the headline per-seat figure once implementation and training are included
  • Requires a substantial minimum commitment (~25 seats), reaching roughly $360,000/year at entry pricing

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
