Pitfalls to watch at work

Jasper

The brand knowledge base takes public product facts only: unreleased products and prices under NDA stay out
Copy in languages other than English comes out with literal calques: have an editor or LanguageTool proofread it before publishing
The model readily writes benefits the product does not have: check every claim about features against the facts

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
