I18nweb
I18nweb is an online i18n translation tool designed to translate structured files (JSON) and content documents (Markdown, TXT) into multiple languages while preserving the original file structure. It targets developers, localization teams, and content creators who need to convert site copy, blog posts, and i18n resource files for frameworks like Next.js, React and Vite. The service uses modern large language models (LLMs) and contextual prompts to produce localized translations that aim to be accurate and natural while avoiding line-by-line mechanical translations.
The product supports batch translation of JSON files, segmentation and contextual translation of Markdown or article content, an in-browser editor for checking and editing translations, and options to download single translated files or packaged results. The service operates on a free-credit and paid-credit model, and enforces limits (file size, number of files, language versions per request) for free users to control costs and ensure stability.
