这个插件太强了！希望能追加中文！
Good for reading difficult Japanese words on the fly, but not that great for studying to put words into your long-term memory because there is no integration with Anki (AnkiConnect). If you can add Anki integration I would use this over Yomichan since the popup design is prettier.
I use this extension on a daily basis. It's extremely handy, and I enjoy it.
什麼都沒有跑出來啊…
cool but maybe pls change the color of the english translations like i mean the text color because it blends w the blue background and i hardly can read it
I love this extension. Its super helpful. If you could get it to work on PDF files while in chrome, that would take away my only complaint.
Thank you for making wonderful tool. I always introduce this function to Japanese Teacher who teach student with dyslexia. It works great.
I really love the extension. It looks like it uses JMdict under the hood, which makes its translations consistent with many other learning tools. However, I have not been able to use it today on google Doc. I don't know whether this is because of an update from either Rikaikun or google, or just because of an issue on my end. Hopefully the issue will be fixed in the future, or will fix itself if my environment's to blame. Great tool anyaway.
Is it possible to enable text-to-speech, not automatically, but when I press a key? This is so it only pronounces the word when I want it to. Best is if the pronunciation could be repeated when my cursor is pointing at the word.
Pretty useful extension. For some reason, it won't let me translate phrases after a comma, so I'm forced to delete commas in sentences to use rikaikun to translate a word. Fixing this issue would be good for user experience.
