Es muy útil, y tiene bastantes términos actuales que normalmente no encontrarías en diccionarios! Hasta expresiones idiomaticas tiene!

I've been using this extension for a year now after using rikaichan on firefox. I have not had a single problem with it, and it has helped me immensely to read japanese texts. I can even OCR scanned texts, convert them to basic HTML pages and then use chrome and rikaikun to read them faster! If I have to make a small complaint, it would be that when I am writing emails, and I forget to turn off rikaikun, it pushes my screen curson into random places. Other than that, it's awesome. Keep up the good work!

Great extension, major benefit to quality of browsing. Unfortunately seems to no longer be working properly for me. After I turn it on it works for maybe a minute, then promptly doesn't work at all (I have to repress the button, even though it says "on"). Not sure if it's my comp, my account, or the extensions fault, cause this just started happening

Not as good as Rikaichan, I don't even know where to install the name dictionary(not even polarcloud works). And sometimes this app doesn't work. Nothing appears when I hover over a word, but this issue is apparently fixed for rikaichain...? And on the extension menu, there's nearly not enough customization other than the colour(lol). Edit: and lol haters hate(not), I've used this extension before on my XP PC and it worked flawlessly, but on my Win 7 one it just fails so badly. It's kind of annoying and I just wish that the dev could fix the issues as I can get Rikaichan perfectly working in an optimum condition while Rikaikun works like...5% of the time(I have to turn it on and off and so on)... (plus you can't even add other language dictionaries, which decreases its value). Tell me why it won't work with my PC with 16GB of RAM and an i5 processor.
