Amazing add-on. I figured out I can greatly enhance my Anki study by using this with Anki web, enabling me to study in full Japanese and just mouseover words I don't know until I remember them (which works because they usually come up again in the same flashcard again). Highly recommend it.
loving it, helps me tremendously. it sees the words even in subtitles and my local files opened in the browser
My go to for learning Japanese. I love this extension!!
Easily my most used extension for learning Japanese. Being able to look at stroke order on the fly and translate single words within sentences in less than a second is a game changer for contextual learning. This extension has never disappointed me from its design, responsiveness, and breadth of content. To whoever is out there releasing stuff like this for free, you have my thanks and admiration!
很棒很好的软件！！就是能不能弄个中文或者日语的字典啊，我看不太懂英文呜呜呜：（
i request developer to help me.this is working partially in my pc before it was working smooth but recently it work partially and show error sign in the extension. Could you please fix it?
Great work! Really made my life a lot easier.
Extremely usefull!

Doesn't let me use it while working on google docs. Someone knows how to fix that?
