AI LangShift

AI LangShift is an open source Chrome extension that instantly translates user-selected text on any webpage using the OpenAI API (GPT-4). With a simple keyboard shortcut, the extension retrieves the selected text, sends it for translation, and replaces it directly on the page.

Features

• Instant Translation: Translate selected text with a single keyboard shortcut.
• Customizable Settings: Configure your OpenAI API key and preferred target language via the options page.
• Wide Compatibility: Works on standard webpages as well as in input fields and contenteditable elements.
• Open Source: Fully open source and hosted on GitHub, encouraging community contributions.
