Pitfalls to watch at work

Adobe Acrobat AI Assistant

• The document is sent to Adobe's cloud for the answer: check whether company policy allows this for contracts under NDA
• Answers about documents in less common languages often switch to English or lose detail, so test on one page before relying on it
• A summary with a page reference can still retell a condition inaccurately: open the cited page for amounts and deadlines

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
