It wont work for me, can you make a video explaining it?
It dictionary itself works fine. I really like the pitch accents, which are surprisingly absent for most dictionaries and textbooks. However, it keeps bugging out and sometimes doesn't turn on when I click the icon. So I go to the extension options to click update or toggle the toolbar icon to make the extension turn back on. Removing and re-downloading doesn't help. Could it be a browser thing? I currently use Edge. And I remember it used to work fine on Edge until a couple months ago... It's just a mild inconvenience for an otherwise very helpful tool.
This is a great extension. I have been a Yomichan user for a long time, but have recently decided to try 10ten, as i've heard quite a few good reviews saying it's better in almost every way. So far i would agree with 1 major issue, possibly one of the most important: Visibility. I find the text contrast and readability to be significantly worse than Yomichan and other similar popup dictionary tools. The text is thin and light and really hard to read compared to most other extensions. So far i haven't found a way to change this other than changing the color theme. The dark theme solves it as a work-around, but it would be nice if the default theme could have it's contrast and visibility boosted a bit.
The best dictionary. I'm amazed. ---------- Doesn't work right now. No idea why.
Used rikaikun for a long time. What sold me is the inclusion of pitch accent. A suggestion/ask: do you guys plan to include Anki integration support?
It's perfect! There are some few words without pitch accent, but it's not a problem and makes my studies SO MUCH FASTER, because we all know it's not that simple to find pitch accent markings in Japanese. The customizations and hotkeys are also quite useful. Thank you!
Unusable. First it won't show me the kanji components like it used to. Then, it won't show up at all after I reinstalled it. The problem still persists when I tried reinstalling it for the 2nd time
The best, so far!
best extension for japanese learning!Almost anything I want！ if there is a japanese to japanese dictionary well be better!
I always want to use hover dictionary like this but Rikaikun and Yomichan weren't working for me. These extensions are so intrusive that when I hover over the words it is so buggy that it becomes impossible to use these extensions. Your extension is the first one allows me to use this kind of dictionary, which is vital to my setup to learn Japanese, as I don't need to switch between tabs when looking for the meaning. I cannot thank you enough for your wonderful work. Please keep up your good work.
