Translation
The translator turns texts and files into one of nine target languages. It runs as a chat, where you can ask follow-ups and refine the translation. It translates Word, PowerPoint and Excel inside the file, so the layout stays as it is.

The target languages
The translator knows nine target languages. German comes in two variants, because spelling and some words differ between Switzerland and Germany.
| Target language in the app | What the translator observes |
|---|---|
| Deutsch (Schweiz) | Swiss spelling with ss instead of ß, Swiss expressions where they differ, and guillemets as quotation marks. |
| Deutsch (Deutschland/Österreich) | ß as the official spelling has it and German quotation marks. If the text or your follow-up makes clear it is for Austria, it uses Austrian expressions. |
| Français | For Swiss texts, Swiss number words and the French names of Swiss authorities and laws. |
| Italiano | For Swiss texts, the Italian names of Swiss authorities and laws. |
| English, Español, Português, Nederlands, Polski | No country-specific rules. |
What the translator observes
- It translates rather than answers. Questions or instructions in your text are translated too, not carried out.
- It replies with the translation only, without a preface or explanation, unless you ask for one.
- Paragraphs, lists, tables, headings and emphasis are kept.
- Figures, amounts, dates, reference numbers, links and e-mail addresses stay unchanged. So do the names of people, companies and products, unless the glossary sets a translation.
- It uses the formal register, such as Sie, vous or Lei, unless the text is clearly informal or you ask otherwise.
- If the text is already in the target language, it says so and asks which language you want.
Translating files
How the translator handles a file depends on its format. Uploads follow the same limits as attaching files in chat. If the chat runs on a model without tools, the translation of an Office file also appears only as text in the chat.
| File | Result |
|---|---|
| Word, PowerPoint and Excel (.docx, .pptx, .xlsx) up to 4 MB | Translated inside the file, the layout stays. Headers and footers, tables and speaker notes are included. Formulas, figures and cell references stay untouched. You receive the translated file in the chat. |
| The translation appears as text in the chat, and the translator offers a Word version. The PDF's layout is not kept. | |
| Other readable formats, older Office formats (.doc, .xls, .ppt) and larger Office files | The translation appears as text in the chat. |
Follow-ups and refinements
Because the translation is a chat, you can keep writing, for example “more formal”, “shorter”, “use another term” or “into Italian instead”. The translator applies such messages to its last translation. Anything else you send, it translates.
The translation chat appears in your chat history like any other chat. No Brain is connected at the start; you can add one in the chat. If you share the chat and someone makes a copy, the copy carries on translating, glossary included.
Glossary: your company's fixed terms
In the Glossary tab, admins set how certain terms are always translated, such as product names or technical terms. The translator applies the glossary in every translation into that language, including inflected and plural forms. All members can see the glossary; only admins can edit it.
Both German variants share one glossary. If you save a term that already exists in that language, its translation is replaced. New, changed and deleted terms apply in running translation chats from the next message. Every change is recorded in the activity log.
| Field | Limit |
|---|---|
| Term | up to 120 characters |
| Translation | up to 120 characters |
| Note | optional, up to 160 characters, for example when the entry applies |
| Entries | up to 300 per language |
