About Pinyin Annotator
Pinyin Annotator is a browser extension that overlays Hanyu Pinyin or Zhuyin annotations over Chinese characters in web pages and video closed captions, enhancing your Chinese language learning journey.
## Features
- Enhanced Video Streaming: Integrate pinyin into Chinese subtitles (closed captions) on video streaming platforms such as Netflix, Disney+, YouTube, Bilibili, and more for an enriched viewing experience.
- Support for Simplified (汉) and Traditional (漢) Chinese.
- Easy Accessibility: Highlight text and click the extension icon to view the Pinyin / Zhuyin of the selected text without disrupting the entire page. Click to look up the word in a dictionary.
- Open-Source: Unlike many browser extensions that do not disclose their code, leaving you uncertain about their operations, this extension allows you to review every line of code. Furthermore, you can build it yourself or contribute to it on GitHub.
- Keyboard shortcut: Use `Alt`(`Option` on macOS) + `Shift` + `P` to toggle annotation (customizable).
