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
