DeepL

DeepL is a translation and language-assistance service with web, document, writing, and API products. The free experience is suitable for quick checks, while paid plans add different limits, security controls, and workflow features. DeepL Write is a separate writing aid rather than proof that a translation is legally or technically correct. For business use, test representative documents with terminology, tables, formatting, and names in every language pair you need. A human reviewer should check consequential translations, especially contracts, health information, and customer-facing instructions. API usage has a different cost model from an individual subscription.
