AI localization for react-i18next apps
Upload your namespace JSON files, pick target languages, pay once, and download locale files ready for useTranslation().
How it works
Three simple steps to localize your react-i18next project. Upload namespace JSON, pay once, and download files ready for I18nextProvider.
Upload namespace JSON
Drop your locales/ namespace files (e.g. locales/en/common.json). We detect {{placeholders}} and _one/_other plural keys automatically.
Select languages
Choose from 52 languages. See transparent pricing based on your file size and complexity before you pay.
Download
Pay once via Stripe. Get a locales/ ZIP ready to pass to I18nextProvider—same namespace structure, translated values.
Transparent pricing estimator
See exactly what you'll pay before uploading. Final quote is computed after upload based on file complexity and languages selected.

One-time payment • No subscription
Built for react-i18next developers
Purpose-built for useTranslation(), I18nextProvider, and namespace JSON—not a generic translation tool.
useTranslation() namespace support
Keeps common.json, auth.json, and all namespaces aligned across every locale so useTranslation('ns') works without changes.
{{placeholder}} safety
Preserves interpolation tokens like {{name}} and {{count}} byte-for-byte—no broken strings in your React components.
Plural-key handling (_one/_other)
Handles react-i18next plural splits such as key_one and key_other so grammar stays correct across all target languages.
Ready for I18nextProvider
Download a locales/ ZIP with the same folder structure—drop it into your repo and pass it straight to I18nextProvider.
Parallel translation
All languages are translated simultaneously. Most jobs complete in under 5 minutes.
One-time payment
No subscriptions, no monthly fees. Pay once per job, download forever.
How react-i18next JSON fits together
react-i18next loads locale files via I18nextProvider. LocalePack generates all namespace files in the same structure your app already expects.
locales/ folder structure
locales/ ├── en/ │ ├── common.json ← source namespace │ └── auth.json ├── de/ │ ├── common.json │ └── auth.json ├── fr/ │ └── ... └── ... (52 locales)
useTranslation() hook usage
// locales/en/common.json
{
"welcome": "Hello {{name}}",
"items_one": "{{count}} item",
"items_other": "{{count}} items"
}
// After i18next.init({ ns: ['common'] })
i18next.t('common:welcome', { name: 'Ada' });
i18next.t('common:items', { count: 5 });Hook API
t()
I18nextProvider
i18next.init()
Placeholders
{{variable}}
Plurals
_one/_other
Why not just use generic tools?
Generic translation tools break useTranslation() namespace JSON, double-brace placeholders, and _one/_other plural conventions.

“Our React app went from English-only to 12 languages in one afternoon. useTranslation() namespaces came back intact.”

“I18nextProvider just worked after dropping in the ZIP. No manual merging, no broken {{variables}}.”

“Saw the price estimate before I uploaded a single file. Exactly what I needed for a one-off localization job.”
