Loccy combines essential i18n functionality (like inline previews and in-place editing) with fine-tuned AI workflows, available right where and when you need them:
Drafted the initial text but aren't sure about the final wording? — Ask Loccy to give you several final options.
Manually adjusting a translation in your native language? — Let AI update the others to match.
And a lot more!
🍒 Cherry on top: Loccy automatically keeps your terminology consistent without a glossary by finding similar existing messages and providing them to the LLM as context.
It takes a little time to learn all the possibilities, but once you do, you won't want to use other tools.
Once installed, Loccy will auto-detect the i18n setup for any open project.
For advanced configuration, run Loccy: Create Config File from the Command Palette. This will create loccy.config.json, and you will have IntelliSense for each setting in the file.
Rules for AI you may want to set first
Set global project rules for the LLM
e.g., "keep brand name untranslated and lowercased"
Set rules per locale
e.g., "de: use informal you - 'du' instead of 'Sie'"
Set rules for keypath creation
e.g., "use snake_case"
