Step 1: Install Extension Install this extension from the Chrome Web Store. Step 2: Install Native Host (Required) Click the extension icon to verify the connection. If not installed, a welcome page will guide you. Download the Native Host installer for your OS (Windows / macOS). Run the install script and wait for completion. Refresh the extension to start using. Step 3: Start Transcribing Open any YouTube or Bilibili video page. Click the extension icon in the browser toolbar to open the sidebar. Click the "Create Task" button. The extension will automatically download audio and start transcribing. Once done, click "Download Result" to get the TXT transcript. Operating System: Windows: Windows 10/11 (64-bit) macOS: macOS 11 Big Sur or above (ARM64 recommended for best performance) Hardware Recommendations: Processor: At least 2-core CPU (4-core+ recommended) RAM: At least 4GB RAM (8GB+ recommended) Disk: At least 2GB free space (for model files and temporary audio) Q: Why is the Native Host required? A: Due to browser security restrictions, large AI models cannot run directly in the extension. The Native Host is a local service program that handles audio downloading and AI transcription, ensuring everything runs safely on your device. Q: How long does transcription take? A: It depends on video length and your device performance. Typically, a 10-minute video takes about 2-5 minutes to transcribe (faster on better hardware). Q: Which languages are supported? A: The Whisper model supports 90+ languages, including but not limited to Chinese (Mandarin, Cantonese), English, Japanese, Korean, French, German, Spanish, etc. The model automatically detects the language. Q: How to uninstall? A: After removing the extension from Chrome, you also need to manually uninstall the Native Host.
