Pros & Cons
Definely
- Works directly within Microsoft Word, reducing workflow disruption compared to separate drafting platforms
- Keeps the lawyer in control of the document rather than fully automating drafting decisions
- Comprehensive coverage of drafting, negotiation, review, and document management
- No published pricing — requires direct sales contact to learn cost
- Enterprise-level legal AI tools generally require a longer procurement process than self-serve software
- Best suited to firms already working primarily within Microsoft Word for drafting
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
