Overview
Inline translation of highlighted text using state-of-the-art AI models (OpenAI, Anthropic Claude, Google Gemini).
Universal Game Translator (Browser extension edition) Why did I make this? Because the default translate option in Chrome makes MANY MISTAKES with Japanese to English. Using the best AI models lets you choose quality over speed - when researching old game blogs and such, it's totally worth it. I use a text-fragment approach that lets the LLM understand the full context (all fragments are sent at once and in order), but still allows us to do a streaming translation with in-place text replacement that doesn't mess up links and images. WARNING: This extension is free and open source, but the LLMs actually cost money and generally make you put in a credit card to get an API key and charge per use. So just be aware that it can add up. Try Gemini, for example; the first million tokens per month are free. * Translate selected text using the latest LLM models (Open, Anthropic, Google) * Support for a secondary "Creative task", for example, summarize everything into a poem at the end or explain cultural notes. * Securely stores your API keys and settings locally in your browser. * Nothing is sent out except the text to the LLM providers you're using. * Customizable prompt template for advanced users. * Context menu integration for easy access. * During translation, a little animation is shown with an option to see the text coming in. * There is a way to see the last prompt/response pair in the settings, good for debugging. New in V1.02: * Improved compatibility * Misc formatting improvements Bugs/Limitations * For security reasons, Chrome doesn't allow extensions to translate certain pages, such as those starting with chrome://. This is unfortunate because it means it can't operate on a reader view I use. <shrug> * Be aware that some models, like Gemini 2.5 Pro, are slower-thinking models, and it could take minutes to process a large translation. Stick to Flash/Mini/Turbo models instead unless you REALLY value quality over speed. SAFETY: I am Seth A. Robinson, a game developer with over thirty released games and creator of many freeware apps including Universal Game Translator and Universal Game Translator: Live. This app does zero tracking or phoning home, it only communicates with the LLMs you setup. (required for translation) The full source code (MIT license) is on github, linked below.
