What is it?

Word Atlas is a browser-based IELTS vocabulary trainer covering 7,298 core words. Each entry includes an original illustration, British and American pronunciation, two original example sentences with Chinese translations, bilingual definitions, collocations, word families and a usage tip. The app runs without an account and stores progress on the user's own device.

Review is handled by FSRS spaced repetition, the same algorithm used in recent versions of Anki, with practice modes that move from recognition to spelling. Learners can start from A2 through C1 to skip familiar words, and a typing studio tracks words per minute separately from memory data. The learned words appear as stars on a WebGL-rendered vocabulary galaxy.

The project is built with TypeScript and React as a PWA with offline caching. The word dataset is released under CC BY 4.0 as JSON and CSV, and the code is MIT licensed. Content was generated with language and image models and checked automatically but not manually reviewed line by line, so the maintainers note that individual entries may contain errors.
