   ChatGPT-i18n – Translate websites' locale json files with AI assistance▲92

   I build this app because I was tired of using Google Translate to translate my locale files (i18n). I wanted to use a more efficient and accurate translation tool. ChatGPT, however, always break my json and cannot translate large contents. So I build this app to solve these problems. Hope it can save your time. github: https://github.com/ObservedObserver/chatgpt-i18n online app: https://chatgpt-i18n.vercel.app/

    I coded my own JSON translation tool to easily localize my side project▲43

    Hi HN, I’m Joan, the developer of Quicklang. I made this app to easily translate and keep in sync all my localization JSON files for my side projects. While searching online for a similar tool, I only found enterprise solutions that do not allow direct editing of JSON files. I used to use ChatGPT to translate the JSON translation file changes before coding Quicklang. However, I realized that ChatGPT only allows you to input short content for translation into another language (even if you provide a .json file), and each time I had to request translations for one language at a time. So, I…

    A simpler way to manage internationalization in component-based apps▲6

    I built this because I was frustrated with how messy translation files get as projects scale. Most i18n solutions force you to manage big JSON dictionaries, spread across multiple files, and then manually wire everything into your UI. It quickly becomes hard to keep things organized, especially in component-heavy apps. This approach is component-first i18n: translations live close to the UI they belong to. That makes it easier to keep things organized, avoid duplication, and scale without the usual chaos of string management. It’s lightweight, works with React/Next.js, and is designed…
