How to Make Copilot Chat Always Reply in Your Language
The Problem
You’re asking Copilot Chat questions in your native language, but the responses come back in English.
Adding “Please reply in my language” to every prompt is tedious and wastes tokens.
The Solution
The github.copilot.chat.localeOverride setting lets you lock the Chat response language.
How to Configure
- Open Settings with
Ctrl + , - Search for
copilot locale - In “GitHub > Copilot > Chat: Locale Override”, enter your locale code (e.g.,
ja,fr,zh-CN)
Example settings.json
{
"github.copilot.chat.localeOverride": "ja"
}The default is "auto", which follows the VS Code display language. If that doesn’t work as expected, setting the locale explicitly will fix the issue.
Other locale examples: "en", "fr", "de", "zh-CN", "ko".
Summary
Set github.copilot.chat.localeOverride to your preferred locale code, and Copilot Chat will consistently reply in that language.
