Translate Your Entire App in Seconds with AI
Manual translation is slow. Hiring translators is expensive. Copy-pasting into Google Translate loses your variables.
LangSyncer's AI translation solves all of this.
One Click, All Languages
Enter your text in English:
Welcome back, {name}! You have {count} new messages.
Click AI Autofill.
In seconds, you get:
- Spanish: Bienvenido de nuevo, {name}! Tienes {count} mensajes nuevos.
- French: Bon retour, {name} ! Vous avez {count} nouveaux messages.
- German: Willkommen zurück, {name}! Sie haben {count} neue Nachrichten.
- ...and 27 more languages
Notice how {name} and {count} stay exactly as they are. The AI knows these are placeholders.
Translate Missing in Bulk
Have 500 keys that need translation? Don't click 500 times.
Click Translate Missing and let AI handle all of them:
- It scans your project for incomplete translations

A typical 500-key project translates in under 5 minutes.
Quality You Can Trust
AI translation quality varies by language pair. Here's what to expect:
Excellent (near-native):
- English ↔ Spanish, French, German, Portuguese, Italian
Very Good:
- English ↔ Dutch, Polish, Swedish, Danish
Good (review recommended):
- English ↔ Japanese, Chinese, Korean, Arabic
For marketing copy or legal text, always review. For UI strings like "Save" and "Cancel"? Ship it.
The Best Part: Context Awareness
The AI uses your translation key for context:
| Key | Source | AI Output |
|-----|--------|-----------|
| auth.login.button | "Sign In" | Knows it's a button, keeps it short |
| marketing.hero.title | "Sign In" | Might elaborate for marketing context |
Same text, different context, smarter translations.
