To translate a document with AI, use a translator that keeps the layout and accepts a glossary of your trade terms. A general assistant works well for adapting the tone of a short text. Have any contractual, legal or published text reviewed by someone who knows the language well.
Translate the text below from [source language] into [target language] for [audience, e.g. distributors in Spain]. Register: [formal / everyday]. Keep these product names unchanged: [list]. Use this glossary: [term = required translation]. At the end, list any ambiguous passages instead of guessing. Text: [paste the text]
Replace the parts in square brackets. Always reread the result before using it. Learn to write a good request

Only checked listings appear in this table, from the most general to the most specialised. No paid placement.
Upload a real Word, PowerPoint or PDF file and check that tables, headings and images stay in place.
The tool must remember the translations you require for product names and your trade vocabulary.
Check that it handles formal and informal ways of addressing people, such as “vous” and “tu” in French, and adapts the phrasing to the target country.
Check whether texts are deleted after translation, excluded from training and hosted in the EU.

DeepL translates text and whole files (Word, PowerPoint, PDF) while keeping the formatting. Its Write module also helps correct and reword text.
For an email or an internal note, it is often enough after a quick review. For a contract, a safety notice or a sales page, plan a review by someone who knows the language well. AI translates sentences well, cultural nuances less so.
Upload the whole file to a translator that handles documents, instead of copying the text. The translated file comes back with the same structure. Still check the areas where the translation is longer than the original.
It depends on the tool and the plan. Some professional plans delete texts after translation and exclude them from training. Check the tool’s page in the Index and the provider’s terms.
