AI 产品解读Mouse-hover dictionary extension for Chrome that shows instant word definitions when hovering over text
Eliminates the need for language learners (especially English-Japanese) to manually look up words in a separate dictionary application, providing instant inline translations
User installs the extension and activates it by clicking the extension icon. When browsing any web page (including PDFs and YouTube), hovering the mouse over a word instantly displays a popup with the word's definition from the built-in English-Japanese dictionary. The popup shows the headword, pronunciation button, and full definition. Users can customize the popup appearance, import additional dictionaries, and use keyboard shortcuts to scroll through definitions. The extension operates entirely locally with no external API calls needed.

- 目标用户
- English language learners studying Japanese / Japanese language learners studying English / Language students reading web content in their target language / Researchers reading foreign-language documents
- All source code is minified/bundled, making individual feature attribution difficult, though the overall architecture is clear
- Dictionary data files are very large (several MB each) making exhaustive inspection impractical, but they consistently contain dictionary entries rather than code
- The options/options.js file is 908KB of minified code containing bundled React and Ace editor libraries, making it hard to distinguish extension-specific code from library code
付费分析未识别到付费功能
No payment platform integrations, no freemium gating, no upgrade prompts, no subscription model found. All keyword hits for 'pro' were from CSS font names (e.g., 'hiragino kaku gothic pro'), minified code variable names, or dictionary data entries. 'Premium' hits were solely from English-Japanese dictionary entries defining the word 'premium'. The extension is open-source on GitHub (github.com/wtetsu/mouse-dictionary) and appears completely free. No Stripe, payment, billing, subscription, or purchase code exists anywhere.

- No login UI, authentication code, OAuth flows, or credential management found anywhere in the extension. All keyword hits for 'login', 'account', 'signin', 'session', 'token' were false positives from dictionary data files (Japanese-English dictionary entries containing these English words as headwords). The extension operates entirely offline using bundled dictionary JSON files and Chrome local storage for settings. No API calls requiring authentication were found.
タッチパネルでのサイズ変更、移動に対応していただけるとありがたいです。(Chromebookをタブレットとして使用時)
Fast, but for JP-EN/EN-JP learners. EN-EN dict without IPA and word pronociation.
非常に重宝しています。 常に使っておりますので、サイトアクセスをすべてのサイトに設定できるようにしていただけると、ショートカットで毎回起動する必要がなく非常に助かりますので、検討していただけないでしょうか。
動画の字幕翻訳が早くて良いと聞いたのに翻訳されない。
とても良いです 単語を保存する機能があるとうれしいです
とても素晴らしい機能なのですが、最近発音ボタンを押しても再生されなくなってしまいました。 Chromeの再起動、パソコン本体を再起動、mouse dictionaryの設定を初期化、mouse dictionaryを一度アンインストールしてやり直す、など様々なことを試してみたのですが改善されませんでした。 発音再生機能がとても便利でしたので、改善法がありましたら教えていただけますと幸いです。
This is an English-Japanese translation dictionary and not a general English dictionary. Should have been directly clear in the title and description.
amazing fast response, local and customizable. I mean this is the only way of breaking language barrier without hullsination.
Uh, not the cleanest looking little thing. If you wanna use a pop-up dictionary to learn jp, just use yomitan. Are there any en-cn dictionaries for this thing?
