Saywell

Translate as you type, polish your English, and track your own writing. You control what leaves your browser.

Saywell 在你正在使用的网页输入框旁提供中英翻译、润色和词汇提示。停顿一下即可获得建议；只有主动点击 Apply 才会替换原文，也可以复制结果。 - 一步授权即可使用开发者提供的免费 AI，无需注册或填写 API Key。共享每日额度有限，可能调整或结束。 - 浏览器支持时可使用本地机器翻译；还可自行连接 MyMemory、LibreTranslate、Google Cloud、Azure 或多组 AI 服务。自选服务可能需要账号、密钥或付费。 - 连接机器翻译和 AI 后可并行获取结果；开启回退时仅尝试已授权服务。 - 支持中英文控制台、目标语言、网站黑白名单、专属配置、临时暂停和可拖动的浮窗。 - 在浮窗内重输建议句子，查看字符差异；练习输入不发送给远程服务。 - 最近 100 条翻译默认仅在当前浏览器会话保留，可搜索、清理、导出或调整数量。创建本地密码保险库后可跨重启加密保留历史、词汇与统计。 - API Key 默认仅存在会话内存中；记住密钥需要已解锁的加密保险库。 数据处理说明：授权后，输入停顿可自动将当前输入框的完整草稿发送给连接的服务；远程 MT/AI 可并行，失败回退可能涉及多家已授权服务。默认免费 AI 由 Cloudflare Workers AI 处理。浏览器本地翻译不上传文本。普通文本框里的敏感内容无法全部识别，请暂停或屏蔽敏感网站。默认记录包含原文与结果的会话历史，以及数字汇总和网站域名的本地统计；可分别关闭和清理。没有广告、遥测服务器或云端历史同步。 边界：仅支持中英文；本地翻译取决于浏览器及语言模型可用性。部分复杂富文本输入框使用复制回退。浏览器内置页、扩展商店及其他受限页面不可用。没有无限或永久免费的服务承诺。 English Saywell helps you express yourself in Chinese and English where you type. Pause to see a translation or polish, then explicitly Apply or copy the suggestion. Your draft is never replaced automatically. - One permission action enables developer-sponsored AI without registration or an API key. Shared daily allocation is limited and may change or end. - Use browser-local machine translation when supported, or separately connect MyMemory, LibreTranslate, Google Cloud, Azure and your own AI configurations. Third-party services may require credentials or payment. - Connected MT and AI can run concurrently. Optional fallback uses only already authorized MT providers. - Switch English/Chinese UI and target language, control websites, pause suggestions and reposition the tooltip. - Retype a suggestion inside the tooltip and compare characters locally, without sending the practice attempt. - Search, clear, export or resize rolling history, initially 100 records in the current browser session. A password-protected local vault can retain history, vocabulary and statistics across restarts. - API keys default to restricted session memory. Remembering credentials requires an unlocked encrypted vault. Data handling: once authorized, typing pauses can send the entire current editor draft to connected providers. MT/AI may receive it simultaneously, and consented fallback can involve multiple providers. Default free AI uses Cloudflare Workers AI. Browser-local translation does not upload text. Sensitive text in ordinary fields cannot be reliably identified; pause or block sensitive sites. Local history contains source/results; local statistics contain numeric aggregates and hostnames, with separate controls. There are no ads, telemetry server or cloud history sync. Chinese/English only. Local MT depends on browser/model availability. Complex editors may offer Copy instead of Apply. Browser internal pages, extension stores and other restricted pages are unsupported. Unlimited or permanent free service is not promised.
