This is an incredible extension for language learning and blows all the competition out of the water; this is really impressive for such a young piece of software. The developers are super responsive and eager to answer questions, solve bugs, and implement ideas community members have on Discord. My favorite use is to watch Japanese anime in Spanish using the AI subtitles so that the subs and the dub both match—something that only one other extension does, but is basically abandonware at this point.

Updated to add that this is the only extension of it's kind to work also on Firefox.
