Diffyn's answer

I started working on Diffyn when I notice that prompting has become an essential part of work across many industries.

Subti started from a personal frustration with learning languages through films. Looking up an unfamiliar word usually meant pausing VLC, opening a translator, copying the subtitle, saving the word somewhere, and then returning to the film. Subti was built to keep that entire workflow inside the viewing experience
