## title: Multi-language Briefings

description: Receive your morning briefing in your native language without losing data fidelity.

The briefing markdown is generated by the LLM in the language you choose. Numbers, app names, and metric labels are preserved in their original form so dashboards still parse correctly.

## Supported languages

| Code   | Language                                                        |
| ------ | --------------------------------------------------------------- |
| `auto` | Auto-detect from `owner_locale` memory fact, falls back to `en` |
| `en`   | English                                                         |
| `tr`   | Turkish                                                         |
| `es`   | Spanish                                                         |
| `de`   | German                                                          |
| `fr`   | French                                                          |
| `pt`   | Portuguese                                                      |
| `ja`   | Japanese                                                        |

## Set your language

```bash theme={"theme":{"light":"github-light","dark":"github-dark"}}
PUT /v1/cofounder/preferences
{ "briefingLanguage": "tr" }
```

## Auto-detect

`briefingLanguage: "auto"` reads the `owner_locale` memory fact and picks the matching language. If the fact isn't set or doesn't match a supported language, the agent uses English.

Or it gets populated automatically the first time you save preferences with a `timezone` that uniquely maps to a country.

## What stays in original language

\- App names
\- Keyword strings
\- Numbers and units (`$`, `%`, `★`)
\- ASC field names (`subtitle`, `keywords`)
\- ISO country codes
\- URLs

This is intentional: the briefing is bilingual-friendly so non-native team members can still read the data even if the prose is in your local language.

## Example — Turkish

```

## Combining with personality

Language and personality are independent. `tr` + `blunt_advisor` gives you a no-fluff Turkish briefing. `ja` + `friendly_mentor` gives you a warm Japanese one.
