Pros & Cons

LegalOn

  • Modular structure allows starting with core contract review and adding capabilities incrementally
  • Strong business momentum (¥10B+ ARR as of October 2025) suggests continued investment in the platform
  • OpenAI partnership signals ongoing AI model improvements
  • Fully loaded cost (~$8,000/user) is roughly 2.3x the advertised base entry price ($3,500/user/year)
  • No public price list — pricing requires direct engagement to understand full modular costs
  • Price increases may accompany AI model upgrades at renewal following the OpenAI partnership

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
