The Japanese Audio to English Subtitles is a Chrome extension designed for real-time transcription and translation of Japanese audio into English subtitles. This tool captures audio directly from browser tabs and utilizes OpenAI's Whisper for speech recognition, alongside GPT for translation, enabling users to enjoy Japanese content such as anime and streams with ease. Key features include a draggable subtitle overlay, adjustable subtitle sizes, and compatibility across various websites like YouTube and Twitch.

To use the extension, users need to install it, input their OpenAI API key, and start playing audio content in Japanese. Subtitles will appear instantly, allowing for a seamless viewing experience. The extension prioritizes user privacy by ensuring that the API key is stored locally and that no data is collected by the tool, making it a reliable choice for fans of Japanese media.
