Pitfalls to watch at work
Harvey
- Harvey's legal sources are strongest for the US and the UK, and its knowledge of other jurisdictions is limited: check provisions in the official sources
- Check case and statute references against the primary source before they go into a client document
- The contract with the vendor must state that client documents are never used to train the model
LanguageTool
- The extension sends text to the service's servers for checking: for documents with trade secrets check your company policy or use a corporate plan with processing in Europe
- Accounting and legal terminology is often flagged as an error: add the terms to your personal dictionary instead of accepting every correction
