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
Spellbook
- Spellbook takes market standards from common law practice: edit clauses on jurisdiction, penalties and currency for your governing law yourself
- Review every tracked change before accepting: a bulk "accept all" brings the other side's positions into the contract
- Contracts with real parties are processed in the cloud: check the vendor's confidentiality terms before the first client contract
