Latest reviews
- (2023-10-25) Greg Morford: 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.
- (2023-10-09) ヤオム: The best dictionary. I'm amazed.
- (2023-09-08) Duri Yudha Nandhita: 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?
- (2023-08-02) Fernando: 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!
- (2023-07-31) HMS Transit: 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
- (2023-07-29) Reborn: The best, so far!
- (2023-07-11) yiyue shi: best extension for japanese learning!Almost anything I want！ if there is a japanese to japanese dictionary well be better!
- (2023-06-12) Lakad Matatag: 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.
- (2023-04-18) Robert Morris: You have done a fantastic job with this extension. Thank you so much for creating it!
- (2023-04-17) Carolyn Geiges: The best thing since sliced bread!
- (2023-03-21) ramu Yaku: that's a best extension for nihongo learner
- (2023-02-05) Andy Benson: Perfect for my needs. Tried yomichan and in comparison this is a lot easier to get going and easier on the eyes imo, no need to install dictionaries and therefore feels a lot less bloaty - this just works right out of the box. Fantastic work. Thank you.
- (2022-11-12) Jonathan McIntyre: In its current state this extension is incredible. Easily chipping away at a complicated syllabary that takes a significant personal effort to even begin to recognize the most important characters, right there at the tip of your mouse cursor. A wealth of information is presented an easy to read format that helps you reinforce all of the intricacies of the language, as you begin to learn them and recognize the patterns. Toggling on the additional Romaji text really helps to speed up the rate at which you can memorize individual symbols, by having a reminder always ready at a flash. 理解チャンプ、「最高」！
- (2022-11-09) Gabriel M.: Incredible!
- (2022-10-28) Aris Koutris: This extension is literally flawless. It does translation, and it does it the best way possible. A lot of information is shown but the results are presented in a structured manner that is easy to understand. It is responsive and the UI is intuitive and highly customizable. Oh, and now mouse support is added. I literally cannot think of any way this extension could be better. Thanks!
- (2022-09-29) Spencer Fricke: I have tried so many tools to help learn Japanese and this is easily my favorite. The level of speed and customizing is perfect. I am mad I was not aware of this for the years of learning Japanese prior. Nothing is more satisfying then seeing a Kanji you forgot/don't know and quickly toggling it on and hovering over it.
- (2022-09-28) Max Moroz: An incredibly useful tool, and amazingly helpful developers! I am using it on both Chrome and Firefox now. The regular updates add a lot of cool features too. For example, now I can use the mouse to move between the tabs of the popup, without pressing any keys. Thanks!
- (2022-09-14) Stefan Gugler: It's like the first time ever I write a review for a chrome app, but it's really a fantastic add-on, congratz. I love the new addition that the pop-up remains and I can browse it with the mouse. I saw almost a year ago that the main dev (?) was talking about WaniKani level integration. I think that would be super useful, especially since a huge part of that userbase uses 10ten to study Japanese through immersion online. Seeing on which level a kanji is taught would be really cool. In any case, thanks for the development!
- (2022-09-13) Eva Creech: This is such a well designed extension. Has worked exactly as needed and has a treasure trove of useful information compactly shown. The new mouse control features are so useful as well! Thanks for all the hard work.
- (2022-08-13) Đào Nhật Phan Anh: lit
- (2022-08-12) Zack Wyvern: This is almost good, but it has this massive disadvantage: you can't mouse over a popup and scroll down it, apparently. I could do this out of the box with all the popup Japanese dictionaries I've used to date EXCEPT this one. There also doesn't seem to be any option to customize the popup time itself. So I'm pretty much out of options if I want to read all the meanings under a popup.
- (2022-08-12) Max Vyner: this extension id goos, the extnesion is good frankly, -max
- (2022-08-12) Parzy Parzybok: i love you
- (2022-08-07) Aka: a double-click function. please. ctrl+alt(or something)is uncomfortable.
- (2022-07-01) Htet Loon: Its a really good extension for Japanese learner. But the really annoying thing is once you move the pointer the popup gonna change. So u can't check the kanji details. And there is no options to change that.
- (2022-06-21) Mixae Mao: I have been using the Rikai family (lol) for YEARS. It's simple, you install it, ENABLE, and bam. You can hover your mouse over runes and it gives you a Pokedex pop out (customizable btw). It also shows the PITCH ACCENT. OTL You literally need this.
- (2022-02-10) Christian Elbrianno: Has more features than any other alternative. Smarter for various translation context, like converting year, date format, and currency.
- (2021-11-27) Francis Pritchard: Excellent extension for learning Japanese.
- (2021-10-10) Kuei: This extension is very useful especially for pitch accent information and word detection system! Thank you very much! この拡張機能は、特にアクセント情報と単語検出システムに非常に役立ちます！ どうもありがとう！
- (2021-06-14) Arzet Ro: Unlike rikaikun, rikaichamp shows pitch accent information, which is a must-have! Because of that, I had to use Firefox when I needed to read something Japanese, but now rikaichamp is here too.
- (2021-05-22) Nico: By far the best of its kind out there. I'd been using this on Firefox and then switched to Brave some months ago and was disappointed by how the only thing similar to rikaichamp was rikaikun, which has a much less flexible word detection system and as of writing this still doesn't have the infinitely useful feature that is pitch accent information. I'm really glad this has finally arrived at the chrome web store.
- (2021-05-16) Bryan F.: I've been waiting for this to hit Chrome/Chromium browsers from Firefox! Just from my initial testing, I can already tell how much better Rikaichamp is than the standard Rikaikun. Way better dictionary that catches more stuff.
