Pitfalls to watch at work

DeepL

On the free version texts may be stored to improve the service: translate contracts and correspondence with details only on a paid plan
Legal terms are translated with a general dictionary: without a glossary "supplier" and "contractor" can swap midway through a document
Scanned PDFs without a text layer are translated with OCR errors, so run OCR first

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
