Installation

The Loccy extension works in any VS Code-compatible editor:

• Visual Studio Code
• Cursor
• Windsurf
• Kiro
• Antigravity

Open the Extensions view (Cmd+Shift+X / Ctrl+Shift+X), search Loccy, and click Install. Available on both the VS Code Marketplace and Open VSX.

Once installed, Loccy auto-detects the i18n setup of any open project using react-i18next, next-intl, or vue-i18n.

Auto-detection is zero-config and covers most projects. Still, add a loccy.yaml: it's where you set the AI styleguide, and it also lets you fine-tune or override detection when needed. If previews still don't show, see Troubleshooting.

The core features work without an account.

AI features require one: the first time you run an AI action, the extension opens your browser to authenticate.
