使用 Precise OCR，你可以通过点击扩展工具栏图标，或使用快捷键快速启动截图功能。Windows 系统默认快捷键为 Ctrl + Shift + O，macOS 系统为 Command + Shift + O。启动后，你可以在页面上自由拖拽选择需要识别的区域，并随时移动或调整选区大小。如果需要取消操作，可以按 ESC 键或点击页面空白区域。

With Precise OCR, you can start a screenshot by clicking the extension icon or using a keyboard shortcut. The default shortcut is Ctrl + Shift + O on Windows and Command + Shift + O on macOS. After activation, you can freely drag to select any area on the page, move the selection, or resize it. Press ESC or click outside the selection to cancel at any time.

在确认选区后，OCR 识别将立即开始。识别过程采用流式返回技术，识别结果会实时显示，无需等待全部完成。扩展支持多语言文字识别，并在识别过程中提供清晰的状态反馈，让你随时了解当前进度。

Once the selection is confirmed, OCR recognition starts immediately. The recognition process uses streaming technology, allowing results to appear in real time without waiting for completion. Multiple languages are supported, and clear status feedback is provided throughout the process.

识别结果会显示在浏览器的侧边栏中，不会遮挡或打断你当前浏览的网页内容。结果支持 Markdown 渲染，可正确显示数学公式、代码块和高亮语法，特别适合技术人员、学生和研究人员使用。对于较长的文本内容，结果会自动滚动，方便持续阅读。

The recognized text is displayed in the browser side panel, so it never interferes with the current webpage. Markdown rendering is supported, including math formulas and code highlighting, making it ideal for developers, students, and researchers. Long text results automatically scroll for easy reading.

在识别完成后，你可以一键将结果复制到剪贴板，并立即在其他应用中使用。复制成功后，扩展会提供明确的提示反馈，确保操作已完成。

After recognition is complete, you can copy the result to the clipboard with a single click and use it instantly in other applications. Clear feedback is shown after a successful copy.

Precise OCR 注重性能和稳定性，能够自动管理资源并在识别结束后正确关闭连接，避免内存泄漏。同时，扩展具备完善的错误处理机制，在异常情况下也能提供清晰的提示信息。它采用响应式设计，适配不同分辨率和屏幕尺寸，并兼容 Chrome、Edge 等主流 Chromium 浏览器。

Precise OCR is designed with performance and stability in mind. It automatically manages resources and closes connections after recognition to prevent memory leaks. Robust error handling ensures clear feedback in case of issues. The extension features a responsive design and works across different screen sizes, supporting Chrome, Edge, and other Chromium-based browsers.

该扩展适用于多种场景，包括从网页、图片或 PDF（通过截图方式）中提取文字，快速复制视频或直播画面中的内容，以及在学习、研究或工作中高效整理资料。

This extension is suitable for a wide range of scenarios, including extracting text from webpages, images, or PDFs (via screenshots), capturing text from videos or live streams, and efficiently organizing information for study, research, or work.

Precise OCR 需要部分浏览器权限以实现完整功能，包括访问当前页面、注入截图和识别逻辑、在侧边栏展示结果，以及将识别内容复制到剪贴板。所有权限仅用于实现核心功能，不会用于与 OCR 无关的用途。

Precise OCR requires certain browser permissions to provide its full functionality, including accessing the current page, injecting screenshot and OCR logic, displaying results in the side panel, and copying text to the clipboard. These permissions are used strictly for OCR-related features.
