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.
