Description from store Hover less, read more using the extension's sentence mode dictionary, saves a lot of time Instantly makes any websites in Chinese as your learning resources Look up Chinese / Zhongwen words and phrases while browsing the web Easily change the hanzi's size and font of the page to make reading more relaxing Configurable, and easy to use Can be made to remember 3 websites visited for each word on Recall and Rewrite modules Includes plenty of useful tools for learners of Mandarin Chinese Latest version (optimizations): * Optimized the words separator's processor, it is now using just a 160 KB memory lookup to perform a task. In the past, it was reading the word's HSK level from a big file which causes the words separator memory consumption to spike up to 100 MB; now the words HSK level info is embedded directly into the code, which is just 160 KB in size * Optimized memory footprint for Chinese words separator's dictionary, it can now be just 26 MB. CWS's dictionary can now be made significantly more lightweight than other dictionaries despite CWS having over 180K words (others have 120K words). This can be made possible by making CWS read the dictionary from the database instead of from file. To configure CWS to read the dictionary from the database instead of from file, go to CWS's Options screen and click the button labeled *Save the dictionary to database*. With database use, the dictionary's memory footprint will be reduced from 108 MB down to 26 MB Other file-based dictionaries' memory footprint: * Zhongwen: 42 MB * LiuChan: 82 MB * Inkah: 76 MB * Zhongzhong: 45 MB Versions: https://chinese-words-separator.github.io/versions.html HOW TO USE: Simply go to a web page in Chinese, by default the words are separated by colors.

Latest reviews

  • (2023-02-18) Kamil: The pop-up extension with the widest range of features and customizability options. The menu might seem a bit convoluted and some of the options could be explained better but just invest 15minutes, play around with it and you'll figure it out. Would love the developer to add some more features that would make this extension even more amazing. Very useful.
  • (2022-09-21) Pe0 Mr: Cool
  • (2022-09-04) Naga: There is just so much feature and customization available, this is by far the best pop-up dictionnary extension
  • (2022-08-30) Nguyễn Thơm: Toẹt vời ạ! cực kì hữu ích ạ!
  • (2022-08-25) Ricardo Yap: I believe this is the best pop up dictionary for chrome extension! Because this extension has many unique features, such as words separator, color coding by HSK, pinyin for every word and even a voice on hover.
  • (2022-07-20) Cong Nguyen: I don't know why this plugin has so few users comparing to its very useful feature for new Chinese learner like me? - Pinyin explanation - Words separator - Voice on hover - Translation Definitely one of the best/must have chrome extension for me.
  • (2022-07-02) Công Nguyễn: very useful
  • (2022-06-27) Konte: Great work, that's exactly what I was looking for. Thanks. Just one suggestion: It would be great if it is possible to disable the extension for certain domains. For some pages, especially for dictionaries, it is quite inconvenient (example: https://dict.leo.org/chinesisch-deutsch/b%C3%B9x%C3%ACng ).
  • (2022-01-19) Russell: Excellent, loving it so far!
  • (2021-12-02) Sean kim: Awesome! I really used all Chinese dictionary extensions and removed all and use this only. This is the best. It is even working on kiwi mobile browser. Plus, it will be more useful if i can make the size of Hànzi smaller so that it cannot break the layout of website when it is with pinyin. And when i select dictionary as sentence it is little bit difficult to know which range I am hovering. Anyway, Thank you for making this awesome program.
  • (2021-10-30) Axel Bryan Joel Yañez Meraz: The dictionary function is too slow.
  • (2021-09-22) Dang Van Giang (K16_HL): 真好tool , i like your tool very much, it has beautiful colors and suits perfectly to my needs
  • (2021-08-23) Bumble: Amazing functions and work perfect! Very grateful for this extension.
  • (2021-04-15) Huzail Hassan: 我不知道你读我的想法。。我今天全尝试天找到这种类扩展, 但是我不找到。 我再尝试了然后。 我找到这新扩展那个今天他做了! 不可能!!非常谢谢!

  • (2023-02-18, v: Kamil: Learned words database sync? Learned words list.
    Hi there! First of all, amazing extension you have writtten, it is very useful! I have two questions/suggestions: 1.) Wordlist Sync? Maybe I haven't figured it out but how do I get to sync my known words list across different devices ? I have a windows laptop at work and mac at home. I am logged in with the same google account but I don't think there is a way to sync the word list? I managed to copy the associated file in the extensions folder manually, but that is obviously not very practical. Is there an option somewhere that I missed? If not, any chance to add automatic sync somehow ? 2. Is there a way to show my current learned/unknown word list similar to the 'recall' UI? That might be another way of solving the sync issue above (if sync is not possible). Letting users export/import known word lists to a csv or txt file. Thanks.
  • (2022-11-30, v: Andrew Hunter: Options don't work on subtitles
    I'm running into a problem where options don't apply properly to Netflix or YouTube subtitles. The options work properly with plain text, just not subtitles. For example, I wanted to turn off the English translations under the characters, but it does not work. I love the extension so far! Great work!
  • (2022-11-11, v: IEnableMuch Dev: CWS developer here
    Word dictionary sometimes have a problem, it goes to the rightmost part of the page when hovering the mouse cursor over the heart icon. ----- This problem is fixed in However, is yet to be approved. ----- The problem was accidentally introduced on changes on November 5. ----- As soon as is approved, the fix release ( will be submitted to chrome web store. ----- For the meantime, if you need to save the word's definition to Learning Tracking Sheet, use the keyboard shortcut instead of hovering the mouse cursor on the heart icon, the default keyboard shortcut is letter 'r'. As for copying the definition, the default keyboard shortcut is letter 'c'. ----- Sentence dictionary is working fine
  • (2022-04-27, v: Gary Peterson: Can't get Chinese Word Separator to be authenticated to use Google API on Google sheets
    I'm using Chrome browser with Chinese Word Separator but cannot get it to authenticate to use Google API on my Google sheets. I'm using Google as my search engine. Everything else on Chinese Word Separator works great. When I right click the red heart, it says it's copied into the "Copied Definitions in Tab-delimited spreadsheet" but it doesn't copy onto my google docs. When I left click it says "Chinese Words Separator is not yet authenticated to use Google API on your Google Sheet. Quit the browser and click (heart) again......" When I click the heart or press "r" nothing happenss. I have set up my own google docs and it is linked correctly..
  • (2021-08-29, v:8.5.1) Bumble: What is the meaning and function of '月' when the extension icon is clicked?
    What is the meaning and function of '月' when the extension icon is clicked? I really appreciate your extension. Brilliant one!
