Features & Capabilities

Pinyin Annotator is a powerful browser extension that overlays Hanyu Pinyin annotations directly on Chinese characters found in webpages and video closed captions. It enhances your viewing and reading experience by integrating pinyin with subtitles on popular streaming platforms like Netflix, Disney+, YouTube, and Bilibili. The extension supports both Simplified (汉) and Traditional (漢) Chinese, making it versatile for learners and enthusiasts.

Designed for ease of use, you can simply highlight any Chinese text on a page and click the extension icon to instantly see its pinyin without disrupting your browsing flow. Additionally, a customizable keyboard shortcut (Alt + Shift + P) enables quick toggling of annotations. Being fully open-source, Pinyin Annotator allows users to inspect, build, and contribute to its code on GitHub, promoting transparency and community-driven development.

Is Pinyin Annotator Safe?

Risk impact

Risk impact measures the level of extra permissions an extension has access to. A low risk impact extension cannot do much harms, whereas a high risk impact extension can do a lot of damage like stealing your password, bypassing your security settings, and accessing your personal data. High risk impact extensions are not necessarily malicious. However, if they do turn malicious, they can be very harmful.

Pinyin Annotator requires some sensitive permissions that could impact your browser and data security. Exercise caution before installing.
