AI localization for i18next apps
Upload your namespace JSON files, pick target languages, pay once, and download a ready-to-use locales ZIP.
{{placeholder}} & plural-safe
Multiple namespaces
Transparent pricing
How it works
Three simple steps to localize your i18next project. Translations run after payment—we queue jobs and generate namespace files in minutes.
01
Upload namespace files
Drop your JSON namespaces (e.g. locales/en/common.json). We detect i18next structure and plural keys automatically.
02
Select languages
Choose from 52 languages. See transparent pricing based on your file size and complexity before you pay.
03
Download
Pay once via Stripe. We return a ZIP mirroring locales/{lang}/ with double-brace placeholders and _one/_other keys preserved.

One-time payment • No subscription
Built for i18next developers
Purpose-built for i18next JSON namespaces, double-brace placeholders, and plural keys—not a generic translation tool.
Namespace support
Keeps common.json, auth.json, and nested namespaces aligned across every target locale in your ZIP.
{{placeholder}} safety
Preserves i18next interpolation tokens like {{name}} and {{count}} exactly—no broken strings after translation.
Plural-key handling (_one/_other)
Handles i18next-style plural splits such as key_one and key_other so grammars stay correct per language.
Ready output (namespace ZIP)
Download a locales/ tree ready for i18next.init() or react-i18next—same paths, translated values.
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 i18next JSON fits together
i18next projects often split strings by namespace under locales/{lang}/. LocalePack generates the same structure for every language you pick.
locales/ folder structure
locales/ ├── en/ │ ├── common.json ← source namespace │ └── auth.json ├── de/ │ ├── common.json │ └── auth.json ├── fr/ │ └── ... └── ... (52 locales)
i18next.t() 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 });Runtime API
t()
Config file
i18next.init()
Placeholders
{{variable}}
Plurals
_one/_other
Why not just use generic tools?
General-purpose translation tools often break i18next namespaces, double-brace placeholders, and _one/_other plural conventions.
