How it works

Three steps to multilingual

No 2-week i18n project. Paste a prompt, review, ship.

01
Set up your i18n library
Pick your framework. Get a ready-made prompt for your exact stack.
next-intlreact-i18nextvue-i18nsvelte-i18n+ more
02
Extract & convert strings
Agent finds every hardcoded string, rewrites to t() calls, syncs keys to your dashboard. Do it screen-by-screen or one-shot.
i18dev extract --write
03
Review translations. Pull. Ship.
Team confirms in the dashboard. One command syncs back to your repo.
i18dev pull --confirmed

Homepage.tsx

Code

const t = useTranslations('homepage');

export function Homepage() {

return (

<div>

<h1>The Open Source alternative to Harvey and Legora.</h1><h1>{t('hero.title')}</h1>

<p>All the features without an enterprise contract.</p><p>{t('hero.subtitle')}</p>

<a href="/github">GitHub</a><a href="/github">{t('cta.github')}</a>

);

Full localization

Localization is not just translation.

Internationalization (i18n) is the engineering work that prepares your app for multiple languages — locale files, keys, and t() wiring. Localization (l10n) is adapting the product for each market: copy, layout, currency, dates, and cultural tone.

Translation changes words. Localization adapts the product identity: copy, layout, images, dates, currency, legal requirements, payment methods, and cultural signals.

Translation only

Words changed. Product did not.
