Where the content comes from

Frequency rankings
Phrasal verb rankings follow the PHaVE List, an academic frequency ordering. A lower rank means a more common verb.
British English
Spelling, idiom and usage are British throughout. Where usage differs from American English, the British form is given.
Curated
Definitions and examples are written and reviewed for teaching use rather than scraped from a dictionary.

How it is built

The platform is self-hosted and built entirely from free and open source software: Astro for the site, Directus as the content store, PostgreSQL, Meilisearch for search, and LiveKit for online classrooms. The source is licensed underAGPL-3.0.

There is no advertising, and no third-party analytics or tracking of any kind. See GDPR compliance for exactly what is and is not collected.
