NOTES ON FOCUS
The best ideas arrive when you have room to think.
Good tools let you stay in the flow.
EchoLingo点击播放，看看回声译如何接上你的阅读。Press play and watch the flow meet the page.
不读取你的屏幕或选区，不调用真实翻译服务。应用默认使用 Alt + D、Alt + S，另有独立的 F1 截图入口；快捷键可修改、清空或自定义。Mac 上 Alt 对应 Option。This preview does not read your screen or selection, and it does not call a translation service. The default shortcuts are Alt + D, Alt + S, and a separate F1 screenshot action. You can change, clear, or customize them. On a Mac, Alt is Option.
01
选中文字、框选识字、本机中英互译，或接上你自己的服务。按需出现，用完即走。Select words, read a region, translate Chinese and English on the device, or connect a service of your own. It shows up when you call it.
在原应用中选中文字，按 Alt + D。原文自动填入浮窗并翻译。没有选中文字时，空按可以直接输入。Select text in the app you are already using, then press Alt + D. EchoLingo fills the popup and translates it. Press the shortcut with nothing selected, and you can type instead.
Mac 上 Alt 对应 Option。快捷键可在设置中修改。Enter 翻译，Shift + Enter 换行。On a Mac, Alt is Option. Shortcuts can be changed in Settings. Enter translates, and Shift + Enter inserts a line break.
按 Alt + S，用鼠标左键拖动框选。松开后自动识字、填入原文并翻译。Esc 随时取消框选。Press Alt + S and drag with the left mouse button. When you release, EchoLingo reads the text, fills it in, and translates it. Esc cancels the selection.
默认本机 OCR。框选时桌面保持实时可见。只有你改选云端 OCR，图片才会上传。Local OCR is the default, and the desktop stays visible while you drag. A picture is uploaded only if you explicitly choose a cloud OCR service.
Windows 免安装包与安装包均内置中英离线翻译，无需 API Key。文本由本机模型处理，不会自动改走云端。Both Windows packages include offline Chinese–English translation. No API key: an on-device model handles the text, and it does not silently switch to a cloud service.
macOS 上的系统翻译是另一项能力，需要 macOS 26+ 和你事先准备好的语言模型。On a Mac, system translation is separate. It needs macOS 26 or later and a language model you prepare first.
翻译可配置 OpenAI 兼容接口的端点、模型与提示词，以及 DeepL、LibreTranslate。OCR 可另选云端 OCR、兼容视觉模型或自定义 JSON 网关。Translation can use an OpenAI-compatible endpoint, model, and prompt, or DeepL and LibreTranslate. OCR can use a supported cloud service, a compatible vision model, or a custom JSON gateway.
翻译与 OCR 分别配置。密钥保存在系统凭据库，不会写入历史。Translation and OCR are configured separately. Keys stay in the system credential store and are not written into history.
翻译之外，也能顺手截图 · 0.2.15Beyond translation · 0.2.15
留一张报错、圈出要改的地方，或分享眼前的画面。无需翻译时，回声译也有独立的全局截图入口。Capture an error, point out a change, or share what is on screen. When you do not need a translation, EchoLingo has a separate global screenshot shortcut.
应用运行时可用；快捷键可在设置中修改，部分键盘需配合 Fn。全程本机处理，不调用 OCR、翻译或上传服务。Available while the app is running. Change the shortcut in Settings; some keyboards need Fn. Capture and editing stay local, without OCR, translation, or uploads.
F1 唤起，悬停看轮廓；点击选窗口，或拖动框选。Esc 取消。Press F1, hover for an outline, then click a window or drag a region. Esc cancels.
在同一原位编辑界面再次调整截图范围，直接在画布上输入文字或便签。用画笔、高亮、椭圆和编号箭头标重点；局部擦除笔画，选中标注移动或再编辑，也能固定贴图对照。Adjust the capture bounds again in the same in-place editor, and type text or notes directly on the canvas. Mark details with a pen, highlighter, ellipses or numbered arrows; erase parts of strokes, move or re-edit annotations, and pin a reference image.
✓ 复制带标注的最终图片；X 放弃本次未保存内容；↓ 将 PNG 保存到设置的文件夹（默认桌面）并复制，以截图时间命名。不会自动保存。✓ copies the final annotated image. X discards this unsaved capture. ↓ saves a timestamp-named PNG to your configured folder (Desktop by default) and copies the image. Nothing is saved automatically.
02
离线模型、Mac 系统翻译、自定义 API，可以同时启用多个服务，对照不同表达。OCR 独立管理；免费翻译与 OCR 推荐分开列出，可折叠查看。An offline model, Mac system translation, or a custom API. Several services can stay on at once, so you can compare how they phrase the same line. OCR is managed separately, with separate, collapsible free-service recommendations for translation and OCR.
Windows 中英离线翻译包内置语言模型，无需 API Key。文本在本机处理，不会自动切换到云端服务。The Windows build includes an on-device Chinese–English model. No API key is required, and the text stays on your computer.
预览包能力以对应版本说明为准。What a preview build includes is described in that version’s notes. It does not silently switch to a cloud service.
03
平时驻留托盘或菜单栏，需要时用快捷键唤起。翻译浮窗点击外部隐藏，钉住后保留。使用系统 WebView，不捆绑 Chromium。It stays in the tray or menu bar and appears when you press the shortcut. Click outside to hide the translation popup, or pin it to keep it. It uses the system web view and does not bundle Chromium.
截图在本机识别。选择云端 OCR 时才上传图片。本机 OCR 配合云翻译时，识别后的文字会发送给所选翻译服务。Screenshots are recognized on the device. A picture is uploaded only when you choose cloud OCR. If local OCR is paired with a cloud translator, the recognized text is sent to that translation service.
应用不加入使用遥测，不在后台持续轮询剪贴板。历史保存在本机。官网没有统计脚本，也不收集 API Key。The app does not send usage telemetry, and it does not keep polling the clipboard. History stays on the device. This site has no analytics script and does not collect API keys.
04
Windows 与 macOS 0.2.15 内测版现已开放下载。升级前先从托盘或菜单栏完整退出旧版。The 0.2.15 test prerelease is now available for Windows and macOS. Quit the previous version from the tray or menu bar before you upgrade.
统计 GitHub 当前公开版本（含内测）的安装包与 Windows 免安装 ZIP 下载次数，不是独立用户数。不含源码、校验文件及已删除的应用包。Installer and Windows portable ZIP downloads across currently published GitHub releases, including previews—not unique users. Excludes source code, checksum files, and deleted packages.
启用 JavaScript 后显示下载量；不影响下载。Enable JavaScript to view counts; download links work without it.
推荐免安装 ZIP：完整解压后打开 Start-EchoLingo.cmd，内含中英离线引擎与双向模型。需系统已安装 WebView2 Runtime。Recommended: portable ZIP. Extract all files and open Start-EchoLingo.cmd. Includes the offline Chinese–English engine and both models. Requires WebView2 Runtime.
下载 Windows 免安装版Download portable ZIP 也可下载 EXE 安装版Or download the EXE installer菜单栏驻留与原生 OCR。系统翻译需 macOS 26+ 及已准备的语言模型。Lives in the menu bar, with on-device OCR. System translation needs macOS 26 or later and a language model you have prepared.
下载 macOS 测试版Download for macOS跨应用取词与完整区域 OCR 流程尚未完成。目前不开放下载。Cross-app selection and the full region-OCR flow are not finished. There is no download yet.
关注项目进展Follow the project0.2.15 双平台内测版。 Windows x64 / Apple 芯片 Mac · 2026 年 11 月 4 日（UTC）。0.2.15 test prerelease for both platforms. Windows x64 / Apple silicon Mac · 4 November 2026 (UTC). 版本说明Release notes · SHA-256 校验值SHA-256 checksums · 发布清单Release manifest · 全部发布All releases
0.2.15 更新：修复 Mac 窗口拖动缩放结束时可能回弹的问题；改进 Codex 嵌套选区中的被动 AXButton 恢复，不主动点击控件，也不放宽受保护内容限制。新增复制回退终止原因诊断，并在翻译失败后保留脱敏的错误元数据；该诊断不保存原文、译文或密钥。New in 0.2.15: Fixes possible Mac window snap-back after resizing and improves passive AXButton recovery within nested Codex selections, without clicking controls or relaxing protected-content limits. Adds copy-fallback termination diagnostics and retains sanitized error metadata after a translation failure, without storing source text, translations or keys in that diagnostic.
需要上一内测版？Need the previous preview? 0.2.14 安装包与版本说明0.2.14 installers and release notes（仍为内测预发布版本。） (Also a prerelease.)
本次验证涵盖同一源码提交的双端全新构建与安装包静态检查；最终 Mac DMG 内完整应用的实际启动、设置 WebView、重复启动与重新打开、原生 Swift 自检及窗口缩放夹具；以及最终 Windows ZIP 的解压启动、设置 WebView、第二次启动转发、双向离线模型、内嵌捕获自检与原生焦点回归。这些有界验收不代表真实 Codex 聊天选区、用户电脑权限、物理多屏／混合 DPI、截图／OCR 全量现场验证或断网证明；Apple 翻译策略自检也不等于调用真实引擎。详见 0.2.15 版本说明。Validation covers fresh builds from the same source commit on both platforms and static package inspection; launching the complete app from the final Mac DMG, settings WebView, repeat launch and reopen, native Swift checks and resize fixtures; and final Windows ZIP extraction and launch, settings WebView, second-launch forwarding, both offline models, embedded capture checks and native-focus regression. These bounded checks do not establish real Codex chat-selection behavior, permissions on your computer, physical multi-display/mixed-DPI behavior, full screenshot/OCR field validation or disconnected operation. Apple translation-policy checks do not call the real engine. See the 0.2.15 release notes.
这是内测预发布版本，不是稳定版。Windows 未商业签名；macOS 使用 ad hoc 签名，未经 Apple 公证。系统可能提示风险或要求重新授权，请仅安装来自本仓库发布页且校验值相符的文件。This is an internal prerelease, not a stable release. Windows has no commercial code signature; macOS uses ad hoc signing and is not notarized by Apple. Your system may show warnings or request permissions again. Install only files from this repository’s release page with matching checksums.
Windows 推荐下载 ZIP 并完整解压，打开 Start-EchoLingo.cmd；也可选择 EXE 安装版。Mac 打开 DMG 后拖入“应用程序”。On Windows, download the recommended ZIP, extract all files and open Start-EchoLingo.cmd, or choose the EXE installer. On a Mac, open the DMG and drag EchoLingo into Applications.
在应用设置中检查所需权限，并选择本机、系统或自定义服务。云服务需自行配置账号与凭据。In Settings, check the permissions you need and choose on-device, system, or custom services. Cloud services need an account and credentials you set up yourself.
选中文字按 Alt + D；图片文字按 Alt + S 左键框选。Mac 使用 Option，可在设置中改键。Select text and press Alt + D. For words in an image, press Alt + S and drag with the left button. On a Mac, use Option. You can change the keys in Settings.
只想留一张图？按 F1，悬停看轮廓，点击选窗口或拖动框选；Esc 取消。部分键盘需配合 Fn，也可在设置中改键。Just need a picture? Press F1, hover for an outline, then click a window or drag a region; Esc cancels. Some keyboards need Fn, or you can change the shortcut in Settings.
由你用快捷键主动触发。选词翻译先取得当前选区，再展示浮窗；区域 OCR 由你手动框选。应用不会在后台持续读取屏幕或轮询剪贴板。You start it with a shortcut. Selection translation reads the current selection, then shows the popup. Region OCR uses a region you draw. The app does not keep reading the screen in the background, and it does not poll the clipboard.
Windows 中英离线包无需 API Key；macOS 系统翻译要求 macOS 26+ 和事先准备好的语言模型。自定义云端翻译或云端 OCR 通常需要联网及对应服务凭据，费用由所选服务商决定。The Windows offline Chinese–English package does not need an API key. macOS system translation needs macOS 26 or later and a language model you prepare beforehand. Custom cloud translation or cloud OCR usually needs a connection and credentials for that service. The provider sets the fees.
可以。翻译支持 OpenAI 兼容接口的端点、模型和提示词，以及 DeepL、LibreTranslate 等协议。OCR 可以分别配置支持的云端 OCR、兼容视觉模型或自定义 JSON 网关。具体协议、鉴权与支持范围以所用预览版本为准；官网演示不连接你的服务，也不收集密钥。Yes. Translation supports an OpenAI-compatible endpoint, model, and prompt, plus DeepL and LibreTranslate. OCR can be configured separately with a supported cloud OCR service, a compatible vision model, or a custom JSON gateway. Protocols, authentication, and what a given preview supports are described with that version. This website demo does not connect to your service and does not collect keys.
Alt + S 用于识字与翻译。0.2.15 的 F1 截图只截取当时可见的画面：确认选区后画面定格，在原位置标注，不读取被遮挡的窗口内容，也不调用 OCR、翻译或上传服务。可再次调整截图范围，使用画笔、高亮、椭圆、矩形、箭头、文字、马赛克或实心遮挡；支持局部笔画擦除、裁剪、撤销与重做。文字可在图上直接输入和再次编辑，支持便签背景；标注可选中拖动、修改或删除，编号圆点与编号箭头可连续标步骤。截图也能固定为独立贴图窗口，用来对照查看；贴图以图片为主，只保留固定与关闭操作。截图编辑使用单一、持续可用的工具条。✓ 将合并后的最终图片复制到剪贴板；X 放弃本次未保存的截图与编辑，不清空剪贴板，也不删除已保存文件；↓ 保存为 PNG 并复制图片，目录在设置中配置（默认桌面），文件名包含截图时间。同名自动编号，不覆盖已有文件，也不会自动保存。工具条优先放在选区下方，空间不足时移到上方，并保持在屏幕边界内。敏感内容建议用实心遮挡，马赛克不保证不可推断。Alt + S reads and translates text. In 0.2.15, F1 captures only what is currently visible: confirming the selection freezes the picture for in-place annotation. It does not recover covered window content or call OCR, translation, or upload services. Readjust the capture bounds and add pen strokes, highlights, ellipses, rectangles, arrows, text, pixel mosaics or solid redaction; partially erase strokes, crop, undo and redo. Type and re-edit text on the image, optionally with a note background. Select annotations to move, edit or delete them, and label steps with sequential number badges or numbered arrows. A screenshot can also be pinned in its own image-focused reference window, with only pin and close controls. Screenshot editing uses one persistent toolbar. ✓ copies the flattened final image. X discards this unsaved capture and its edits without clearing the clipboard or deleting saved files. ↓ saves a PNG and copies the image; the folder is configured in Settings (Desktop by default), with the capture time in its filename. Name collisions get a numbered suffix—no overwrite or automatic save. The toolbar prefers the space below the selection, flips above when needed, and stays within the screen edges. Use solid redaction for sensitive content; mosaics do not guarantee it cannot be inferred.
点击上方对应系统的下载按钮，也可以前往 GitHub 发布页查看版本。升级前先从托盘或菜单栏完整退出旧版，再安装或替换新版。Windows ZIP 请完整解压到新文件夹，不要直接在压缩包内运行。免安装仅指应用文件无需安装向导：配置、历史与 WebView 数据仍在当前用户的 AppData，密钥仍在 Windows 凭据库中，不会随 ZIP 搬走。启动器不自动下载或安装 WebView2；缺失时按提示前往 Microsoft 官方渠道安装。Mac 首次打开可参考安装说明。Use the download button for your system above, or open the GitHub releases. Quit the old version from the tray or menu bar before you install or replace it. Extract the Windows ZIP into a new folder; do not run it inside the archive. Portable means no app installation wizard: settings, history and WebView data remain in the current user’s AppData, and keys remain in Windows Credential Manager, not in the ZIP. The launcher does not download or install WebView2 automatically; if it is missing, follow the prompt to Microsoft’s official source. For a first launch on a Mac, see the installation notes.
