ResponseLanguage enum

The language the AI should use in its response.

Pass this to Prompt to control which language the model writes in. auto is the smart default — the model detects the user's language from their message and replies in the same language.

Prompt(
  language: ResponseLanguage.auto, // matches whatever the user writes
)

For language detection logic, see MessageAnalyzer.

Available extensions

Values

english → const ResponseLanguage

Respond only in English, regardless of the user's message language.

arabic → const ResponseLanguage

Respond only in Arabic (Modern Standard or dialect, depending on context).

Works well for Egyptian Arabic apps — the model respects colloquial phrasing when the system prompt uses Arabic examples.

bilingual → const ResponseLanguage

Respond in both English and Arabic side by side.

Useful for language-learning apps or mixed-audience products where users may be more comfortable in either language.

auto → const ResponseLanguage

Detect the user's language automatically and reply in the same language.

This is the recommended default. MessageAnalyzer detects whether the message is Arabic, English, or mixed, and Prompt.build injects the matching language instruction.

Arabic detection uses the Unicode range ؀–ۿ. If both scripts appear, bilingual behavior applies.
