Language & localization

Oleafly’s desktop interface is available in English and Simplified Chinese (简体中文). Change it while the app is open; menus, settings, tools, messages, and workspace controls update without a restart.

Choose an interface language

1. Open Settings → General.
2. Find Language.
3. Choose System, English, or 简体中文.

System follows your operating system. Choose a specific language when the computer’s language and the interface you want are different, or when a shared computer should keep Oleafly in one language.

What the setting changes

The language choice changes Oleafly’s own interface, including the Library, editor controls, Settings, Oleafly Tools, warnings, and recovery actions.

It does not translate:

• your .tex, .typ, .md, or .bib files;
• the compiled PDF;
• proofreading language or English dialect;
• replies from an AI assistant;
• compiler logs, package names, or metadata returned by outside services.

That separation is useful. You can write an English paper in a Chinese interface, edit a Chinese document in an English interface, or ask an assistant to reply in a language that differs from both.

Set writing and proofreading languages separately

For English spelling and grammar, open Settings → General and choose the Spelling dictionary and English dialect you need. These settings are independent from the interface language. See Spelling, grammar & academic style.

For an assistant, state the output language in your request or save it in Custom instructions. The interface language does not rewrite your prompt or force the model’s reply language.

More languages

Simplified Chinese is the first localized desktop interface alongside English. More interface languages are planned, but they are not available in the desktop app yet.

If one screen does not update after a language change, leave that screen and open it again. If a label remains untranslated, include the screen name and app version in an issue report.
