Frequently Asked Questions

Can I use this tool without an API key?

Yes, a local fallback phrase library provides basic translations if no AI key is configured. For accurate register control, especially with honorifics, connecting an AI provider is recommended.

What do the tone markers actually mean?

Markers identify the grammatical devices creating the register, such as pronouns, verb forms, or softening phrases. They help you understand why a version sounds formal or friendly in the target language.

Which target languages are supported?

The tool supports Spanish, French, German, Japanese, Chinese, and Portuguese. Each language receives three distinct tone variations: formal for business, casual for chat, and friendly for warm interactions.
