Why we built these
Most language tools sell a course. These don't — they help you decide what to study and how to spend your time. The tools are linkable, citation-friendly, and free for any blogger, teacher or learner to share.
If you find them useful, the best way to support us is to download Clue on iOS — the app behind the data. It turns any podcast, YouTube video or EPUB into tap-translatable content with a 27 000-word offline dictionary.
