浏览器翻译 作者： Eliya

两种翻译方式，中间不隔任何东西。

划词后出现一个小按钮，按下去，你开启的每个服务并排给出答案——一句可以有
好几种译法的话，正需要看见它们的分歧。服务可以直接在面板上增删。

整页翻译把译文放在原文旁边，逐段对照。一个按钮在双语 / 只看译文 / 只看
原文之间切换；目标语言和翻译服务不用离开页面就能换。原文从不被改写，只是被
包起来，所以还原之后和原来一模一样。

另外还有：悬停翻译、翻页也不会关掉的独立面板、用系统自带语音朗读、以及
iframe 内容翻译。

翻译服务

免密钥开箱即用：Google 翻译、有道词典（仅查词）。

需自备密钥：ChatGPT、Claude、Gemini、DeepSeek。密钥只存在你自己的浏览器
里，除了它所属的那家服务不会发给任何人。模型、端点、提示词、额外请求参数
都可以改——比如关掉 DeepSeek 的深度思考，翻译会快很多。

不做的事

没有账号、不用登录、没有付费墙、没有每日限额、没有试用期。没有统计、没有
遥测。没有自己的服务器——每个请求都从你的浏览器直连你选的那家服务，中间
没有需要你信任的第三方。什么都不记录：没有历史，没有收藏。

Two ways to translate, and nothing in the way.

Select text and a small button appears. Press it and every service you
have turned on answers side by side, so you can see where they disagree —
which is exactly what you want from a phrase that could go several ways. Add
or remove a service from the panel itself.

Translate a whole page and the translation goes in beside the original,
paragraph by paragraph. Switch between bilingual, translation only and the
original with one button; change the target language or the service without
leaving the page. The original is never rewritten, only wrapped, so restoring
it gives back exactly what was there.

Also: hover translation, a standalone panel that survives page navigation,
reading aloud through your system's own voices, and translation inside
iframes.

Services

Free and ready to use: Google Translate, Youdao (dictionary lookups).

With your own API key: ChatGPT, Claude, Gemini, DeepSeek. Keys are stored on
your machine and sent to nobody but the service they belong to. The model,
the endpoint, the prompt and any extra request parameters are all yours to
change — DeepSeek's reasoning pass can be switched off, for instance, which
makes it markedly faster at translating.

What it does not do

No account, no sign-in, no paywall, no daily limit, no trial. No analytics
and no telemetry. No server of its own — every request goes straight from
your browser to the service you picked, so there is no middleman to trust.
Nothing is written down: no history, no favourites.
