# Choose a model and answer language

> Set the AI model and output language, separately from the interface and transcription.

Open **Home → Launch Copilot** to set **AI Model** and **Interview language**. Available options are shown in the current menus.

## Choose an AI model

Open the model menu and select an option. Compare structure, detail, and wording with one or two familiar questions. Keep the resume, role, document, language, and question the same for a useful comparison.

## Choose the answer language

**Interview language** primarily controls the language of AI answers. Choose the desired language or **Auto**. It does not specify the speech recognition language for transcription. Try a question before starting to confirm the output meets your needs.

## Interface language

Set **Interface language** under **App settings → Preferences** to change workspace and assistant buttons, menus, and prompts. It is managed separately from the answer language.
