The tool provides an end‑to‑end internationalization workflow for React and Next.js projects. Developers write components in a single source language, using provided JSX wrappers and a translation hook to mark strings. The CLI extracts those strings, sends them to a configurable AI provider for translation, and writes language JSON files. Because it tracks changes, only newly added or modified text is sent for translation on subsequent runs.

It operates without a separate key‑value file, allowing developers to keep the original text in the markup. The system supports rich content such as variables, plural forms, numbers, currency, and dates, and it integrates with Next.js features including middleware, server components, and static generation. A validation command can be run in CI pipelines to ensure all translation files are complete and syntactically correct.

The project is open source and positioned for teams that already have access to an AI model for translation, offering a zero‑key, incremental approach that aims to simplify the process of making a React or Next.js application multilingual.
