Translate selected text with Google Gemini or DeepSeek GenAI Translator is a powerful Chrome extension that lets you translate selected text on any webpage to your target language using your choice of AI provider — Google Gemini, DeepSeek, OpenRouter, or Chrome's built-in on-device AI.
To use this extension, you must create a FREE Google Gemini API key from Google AI Studio (https://aistudio.google.com/api-keys). Sign in with your Google account and generate a key in under a minute — no credit card and no payment required. See the step-by-step guide below.
Note: The Google Gemini API isn't available in every country. If Gemini doesn't work in your region, use OpenRouter — which offers free models — or low-cost DeepSeek instead. The first-run setup will guide you.
