Feature Request: Multi-language Support (i18n) for Codex Desktop App
Summary
Add multi-language/internationalization (i18n) support to the Codex desktop application, starting with Chinese (Simplified).
Problem
Currently, the Codex desktop app UI is only available in English. For non-English speaking users, this creates a language barrier when navigating the interface, even though the AI assistant itself can communicate in any language.
Proposed Solution
- Add a language selector in the app's Settings
- Start with at least: English, Simplified Chinese, Traditional Chinese, Japanese, Korean
- Allow the UI language to be set independently from the conversation language
- Store the language preference in the app's configuration
Use Cases
- Chinese-speaking developers who prefer a Chinese UI
- Teams with mixed language preferences
- Broader international adoption of Codex
Additional Context
The AI assistant can already communicate in Chinese, but the app interface (menus, buttons, settings labels, etc.) remains in English. Adding i18n would significantly improve the experience for non-English users.

The Codex desktop app already has fully localization for many languages. It uses the default language setting in your operating system.
