Pitfalls to watch at work
Copilot in Word
- Compare two versions of a contract with Word's built-in Compare and ask Copilot to explain the changes found: on its own it misses some edits
- Rewriting in a different tone also changes the content: after Rewrite, check amounts, dates and party names against the original
- In the business version Copilot may pull a passage from someone else's document you have access to: check the sources in the answer
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
