To **use AI across languages**, you do not need a translated knowledge base. An agent can answer in the language of the question while drawing on material written in another.

## What multilingual operations usually do

They duplicate, and the duplicates diverge.

- Documentation maintained in two or three languages
- Updates applied to one version and not the others
- Answers differing depending on which version was consulted
- Translation effort repeated with every policy change

## What single-source documentation enables

| Benefit                     | Why                                 |
| --------------------------- | ----------------------------------- |
| **One version to maintain** | Updates cannot diverge              |
| **Consistent answers**      | Everyone draws on the same material |
| **Faster policy changes**   | No translation cycle                |
| **Wider coverage**          | Languages you never translated into |

## How to set it up in Jestor

1. Maintain one authoritative document per topic in **Jestor**, in whichever language suits you.
2. Attach it to the agent as its knowledge base.
3. Note that the agent answers in the language the question was asked in.
4. Let individual users set their own interface language, independently of the system setting.
5. Test with questions in each language your teams actually use.
