Pair Translate is an open-source browser extension designed for web page translation, enabling users to view original and translated text side-by-side. It targets users who frequently encounter foreign language content online and require immediate, integrated translation capabilities without leaving the page context. The primary benefit is an enhanced, non-disruptive reading experience for multilingual web content.

How It Works

The extension operates by appending translated text directly to the original content on web pages, facilitating an "immersive" reading experience. It supports a wide array of translation backends, including major platforms like Google Translate and Bing, as well as popular LLMs such as ChatGPT, Claude, and Gemini, offering flexibility in translation quality and cost. All translation requests are processed locally and routed directly from the user's browser to the chosen service provider, ensuring user privacy.
