How does it work?

Encounters sentences on the site:

- "I always imagined that Roy G. Biv would be best friends with Billy Rubin"

Resulting sentence might look like this:

- "I always imagined that ⠗⠕⠽ G. Biv would be best friends with ビリー Rubin"

And you can hover over them to see the original words. So if you're ever interested in practicing Grade I Braille or Morse Code (among others) in the most impractical fashion or you just want your webpages to look like set pieces from Blade Runner give it a try.

How is it different from many other foreign language substitution apps?

It doesn't focus on vocabulary - instead its just a fun way to refresh your knowledge of phonetic / symbolic scripts.
