Overview
This extension combines three core tools for Douyin and Bilibili: real-time subtitle translation with Soniox speech recognition, Bilibili subtitle translation with Google Translate for greater accuracy from existing text, and batch video downloads from Douyin.
Subtitles appear directly over the video in two lines: the original Chinese text and its translation. You can customize the font, size, colors, and draggable position, and use a subtitle history panel.

The easiest method:
- Click "Install from Chrome Web Store" at the top or bottom of this page.
- On the Chrome Web Store, click "Add to Chrome".

The extension installs automatically and appears on your browser toolbar immediately.
Supported browsers: Chrome, Edge, Brave, and other Chromium-based browsers.
Key Features
🎤 Real-Time Subtitle Translation (Soniox)
Works with both Douyin and Bilibili. It captures tab audio, recognizes speech through the Soniox API, translates it, and displays subtitles over the video in real time. Seven languages are supported: Vietnamese, English, Japanese, Korean, Thai, Spanish, and French.
📺 Bilibili Subtitle Translation (Google Translate)
Designed for Bilibili. It retrieves existing Chinese AI subtitles and translates them in batches through the Google Cloud Translation API. This is more accurate than Soniox because it uses existing text instead of speech recognition. Subtitles stay synchronized with playback and update automatically when you seek.
⬇ Batch Douyin Video Downloads
Scan videos from a Douyin profile, choose a resolution (Highest / 1080p / 720p / 480p / 360p), and download through IDM or your browser. Supports profiles, individual videos, Jingxuan, Discover, and search pages.
🎨 Subtitle Customization
Customize font size, typeface, text color, background color, and opacity. Drag subtitles directly on the video, show or hide the original text, and let every setting save automatically.
📜 Subtitle History
A floating history panel in the lower-right corner shows timestamps, original text, and translated text. Drag it anywhere on the screen.
