About this extension
DualTran keeps the original text on the page and puts the translation next to it, instead of replacing what you are reading.
Highlights
• Two engines at once — Google Translate and any AI model can run together, and both translations are shown side by side for comparison
• 20+ AI providers — OpenAI, Anthropic, Google Gemini, DeepSeek, Moonshot, Zhipu GLM, Qwen, Groq, OpenRouter, Ollama, LM Studio and more, with your own API key; the key stays in your browser
• Selection and full-page translation — translate a selected paragraph instantly, or the whole page in one click
• Text only — code blocks, formulas and navigation are skipped so the layout stays intact
• Privacy first — no account, no analytics, no relay server; text goes only to the translation service you choose
Built for reading foreign-language documentation, papers, GitHub issues, and Reddit or X threads where you want the original and the translation together.
