Translate the web.
Leave the page intact.
整页翻译，
网页还是原来的网页。
As light as Safari's own translation and just as in place — but powered by large language models, so it reads better. And you choose the languages.
和 Safari 自带翻译一样轻、一样原地替换；不同的是，它用大模型翻译，译得更好，语言也由你决定。

Better translations,
no new habits.
译得更好，
用法不变。
Everything happens in Safari's own menu. No floating buttons, no sidebars, nothing added to the page.
一切都在 Safari 自己的菜单里完成。不加悬浮球、不开侧边栏，页面上不多任何东西。
Reads like it was written that way
译得更好
Whole-page context keeps pronouns clear and terms consistent. Code, API names and product names stay as they are, and the tone follows the content.
结合整页上下文翻译，代词指代清楚、术语前后一致。代码、API 名、产品名保持原样，语气贴合内容。
Your languages, your call
语言由你决定
Pick any source and target language, not just a short list. Tessel detects the language from the text itself, paragraph by paragraph — and remembers your corrections per site.
源语言和目标语言随你选，不限于少数几种。按正文内容逐段识别语言，识别错了可以改，改过的网站会记住。
The page stays the page
网页还是原来的网页
Text is replaced in place. Links, bold, code, lists and tables survive, and the original is one tap away. New content that loads as you scroll gets translated too.
原地替换文字，链接、加粗、代码、列表和表格都保留，一键显示原文。滚动加载出来的新内容也会接着翻。
Fewer taps
少点几次
Always or never translate a site. Keep translating as you browse the same site. Turn on Auto Translate, and pages you've seen before appear translated instantly.
为常看的网站设置「总是翻译」或「从不翻译」，同一网站里继续浏览自动接着翻；打开「自动翻译」，看过的页面译文立刻出现。
Works without AI, too
不接大模型也能用
Apple Translation is the default. It runs on your device, works offline and costs nothing.

Your key, your rules
你的 Key，你做主
Use your own AI provider and API key. Page text goes straight to the provider you choose — never through our servers. No account to create.
使用你自己的大模型服务商和 API Key，网页内容直接发给你选择的服务商，不经过我们的服务器。无需注册账号。
Two ways to translate.
两种翻译方式。
Start with Apple Translation. Add an AI model when you want the best result.
先用 Apple 翻译；想要更好的译文时，再接上大模型。
