How LLMs Excel at Localization

February 8, 2026 Rens Jaspers Short thoughts i18n LLM AI Internationalization

I'm incredibly happy that we finally have fast and reliable internationalization at our disposal, thanks to LLMs.

For years, i18n was frustrating. Setting up all those pesky translation strings and keeping them in sync was slow and error prone. Trying to translate them was even worse. The translations were almost always bad, because the translator lacked technical context and the developer lacked linguistic context.

Nowadays we don't have any of those problems anymore. Agents are not only the best translators in the world, they also know the full context of your application. And they will gladly keep all your translation strings in sync if you decide to overhaul your app.

i18n won't ever be a bother again.
