DeepL

What is DeepL?

Its reputation rests on output that reads like something a person wrote, particularly between European languages and Japanese, where competitors often produce technically correct but stiff text. DeepL says over 200,000 businesses use it. The free tier translates 50,000 characters a month and one document; paid plans raise that, unlock glossaries with real entry limits, and commit to not training on your text. If you handle documents in another language, run the same paragraph through DeepL and a general chatbot and compare.

Three things DeepL does best

1. Translation you can send without rewriting

   Output tends to preserve register, idiom, and sentence flow rather than mapping word by word, which is why legal and marketing teams use it on client-facing text. DeepL Write, sold as an add-on from $7.49 per user per month, then polishes tone and phrasing in the same window.

2. Keeps your document looking like a document

   Upload Word, PowerPoint, Excel, or PDF files and get them back translated with layout, tables, and formatting intact. The free version allows one file per month at up to 5 MB; Individual raises it to three files at 30 MB, Team to twenty, Business to a hundred.

3. Locks your terminology and your data down

   Glossaries force chosen translations for product names and legal terms, though the free and Individual plans cap you at five entries per language pair while Team allows a thousand. Paid plans also carry a no-training commitment plus SOC 2 Type 2 and ISO 27001 certification.
