  description

  WaveShift is an AI video translator for YouTube and Bilibili. It creates synchronized AI-dubbed audio and translated subtitles so you can watch videos in your preferred language without downloading or modifying the original video.
  
  How it works:
  1. Open a YouTube or Bilibili video.
  2. Click the WaveShift translate button in the video player.
  3. Choose the target language and voice mode.
  4. Track progress in the side panel and play the synced AI audio when it is ready.
  
  Key features:
  - AI dubbing with natural voice output.
  - Translated subtitles displayed on the video.
  - Audio overlay synchronized with the original video.
  - Immersive mode that preserves background music, or solo mode for voice-only playback.
  - Side panel for language settings, task progress, usage, and recent translations.
  - Supports English, Chinese, Japanese, Korean, Spanish, French, German, Italian, Portuguese, and Russian.
  - Works with public YouTube and Bilibili videos.
  
  WaveShift does not download, replace, or modify the original video stream. The original video continues to play from YouTube or Bilibili, while WaveShift plays a separate translated audio track in sync.
  
  A WaveShift account is required. Sign up at https://www.waveshift.net/.

  WaveShift brings AI video dubbing directly into the YouTube and Bilibili player.
  
  Open a supported video, click the WaveShift button in the player, and WaveShift prepares a translated audio track plus subtitles that play in sync with the original page video. You keep the source video where it is while reducing the time it takes to understand, review, and reuse foreign-language content.
  
  **How it works:**
  1. Navigate to a supported YouTube or Bilibili video
  2. Click the WaveShift Translate button inside the player
  3. Track progress in the player or side panel
  4. Play AI-dubbed audio and translated subtitles in sync with the source video
  
  **Features:**
  - In-player Translate button for YouTube and Bilibili
  - AI-dubbed audio synchronized with the original video timeline
  - Translated subtitles displayed directly on the video
  - Streaming progress states while the dubbing pipeline runs
  - Multiple voice engines: Voice Clone (Qwen3), Kokoro neural voices, and Edge TTS
  - Keep-background audio mode, or voice-only mode without background audio
  - Chrome Side Panel for managing tasks, history, cancellation, and progress
  - Supports 10 target languages: Chinese, English, Japanese, Korean, Spanish, French, German, Portuguese, Russian, and Italian
  
  **How audio overlay works:**
  WaveShift does not modify, download, or replace the video playing on YouTube/Bilibili. WaveShift processes the source media on its backend to generate translated audio and subtitles, then the extension plays that separate AI-generated track over the original page video in sync.
  
  **Privacy and platform access:**
  WaveShift uses a WaveShift-issued extension access token for authentication. The Chrome Web Store build does not request the `cookies` permission and does not read or transmit YouTube, Bilibili, or WaveShift website cookies.
  
  Bilibili may block anonymous server-side imports for some videos. When that happens, use the official download version from waveshift.net/extension; it can use your Bilibili login cookies after local installation.
  
  **Note:** A WaveShift account is required. Sign up for free at waveshift.net.
