ローカル LLM で翻訳・要約する。ページ本文は 127.0.0.1 の ctrans serve にだけ送る。 REQUIRES A COMPANION APP ctrans is the browser half of a two-part tool. You also need to run the ctrans service and a local language model on the same computer. Setup takes a few minutes and is described at https://github.com/Chloro989/ctrans — if you are not willing to do that, this extension will not work for you. WHAT IT DOES Translate or summarize a whole page, or just the part you selected, using a language model running on your own machine. Click the toolbar icon or use the right-click menu. The result appears in a panel you can move and resize; the page itself is never modified. Languages: Japanese, English, Simplified Chinese, Traditional Chinese, Korean, Russian, Spanish. No cloud service. No account. No API key. No usage limits. It keeps working with the network unplugged. WHERE YOUR DATA GOES To 127.0.0.1 — your own computer — and nowhere else. The extension holds no permission to reach any other address, and its settings page refuses any address whose host is not 127.0.0.1. It reads a page only when you invoke it, never in the background. No analytics, no telemetry, no accounts, and the developer operates no servers and receives nothing. BUILT FOR HOSTILE PAGES A web page can contain text aimed at the language model rather than at you, hidden where you will never see it: white text on a white background, elements pushed off screen, words split by invisible characters, instructions smuggled inside Unicode control characters. ctrans removes what you cannot see before anything is sent, and normalizes what you cannot read. But filtering is not the defense, because no filter reliably detects an instruction written in ordinary prose. The defense is the shape of the request. The translation call is built with no tools, no function calling, no conversation history, no filesystem access, and no network access beyond the one local endpoint. A model that does follow an injected instruction has nothing to act on. The model's output is treated as untrusted in turn: it is rendered as plain text inside a closed shadow root, never as HTML.
