What it does
The DeepL API translates text and whole documents (Word, PowerPoint, PDF and more) with DeepL's AI translation, known for natural-sounding results, between more than 30 languages. You can set formality, use glossaries for your own terms and improve texts with DeepL Write. Responses are JSON. The DeepL API Free plan gives 500,000 characters per month with a free account (it uses its own server, api-free.deepl.com); DeepL API Pro is paid per character.
