Pitfalls to watch at work
Grammarly
- The extension reads everything you type in the browser, including form fields: decide in your corporate policy whether it is allowed on work computers
- Rewriting a sentence changes its legal meaning: in English contracts and claims, accept only spelling fixes
- For text in other languages the service offers almost no suggestions; use LanguageTool for that
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
