NTranslate — AI translator

AI translation of websites, selected text and YouTube subtitles with your own OpenRouter key. Keeps layout and fonts.

NTranslate translates the web with AI models of your choice, and it keeps pages looking the way they were designed. NTranslate requires your own OpenRouter account and API key, it does not work without them. You can start for free: several free models work with a zero balance, within OpenRouter's daily limit for free models. Paid models need an OpenRouter balance: you pay OpenRouter directly, usually a fraction of a cent per page, and pick any model, from cheap and fast to the most capable. There is no subscription and no NTranslate account. WEBSITES • Translates whole pages and keeps layout, links and fonts • Text appears as the model answers, the first screen comes first • Remembers translations, so a page you return to opens instantly and for free • Bilingual mode with the translation under the original YOUTUBE SUBTITLES • A button in the player translates the video's ready-made subtitles • The model knows the title, author and description of the video • Songs are translated as lyrics, with the chorus identical every time • Original, translation or both, in fullscreen too, plus the full text next to the video TEXT, IMAGES AND MORE • Translate a selection, explain it in context, or get a dictionary card for a word under the cursor • Translate text on images: all of it in a neat window beside the picture, with notes on wordplay • A translator in the side panel • Read translations aloud with AI voices, levelled to one volume YOU STAY IN CONTROL • Free models to start with, and a quick check of whether any model can translate • Everything can be switched off • Monthly spending limit • Light and dark themes PRIVACY Nothing is sent until you agree inside the extension. What you translate goes to OpenRouter and the model provider you chose, and only when you start a translation or turn on automatic translation. Nothing goes to the developer. Your key and saved translations stay in your browser. NTranslate is an independent project and is not affiliated with OpenRouter, Google or YouTube. An optional link in the settings lets you support development on Boosty; no feature depends on it.
