AI Translation Chrome Extension

Project Description

This project is a Chrome Extension that communicates with a locally running FastAPI backend to translate text using the Gemini AI model. The extension captures user-selected text → sends it to your Python server → receives the translation → displays it instantly.

Features

• Select text on any webpage and translate it immediately through the popup interface.
• Automatically expands abbreviations to full English phrases before translating.
• Retrieves a list of common translation languages from the backend.
• Uses Google Gemini Flash Lite for accurate, AI-powered translation.
