CopyCatch - OCR Image-to-Text Reader

Select any visible image or page region and turn it into editable text locally.

CopyCatch turns visible text into editable text without sending the selected image to a server. 1. Open a normal web page. 2. Click CopyCatch or press `Alt+Shift+C`. 3. Draw a box around the text. 4. Review, edit, copy, or download the result. What CopyCatch includes - Offline OCR performed on your device - Precise region selection - Compact editable results on the same page - Directly draggable and edge-and-corner-resizable same-page result panel - Source-evidence preview with highlighted OCR line locations - Preserved line structure plus rich and plain-text copying - Neutral logo/unsupported-glyph placeholders instead of invented text - Full-page Evidence + text, Source evidence, and Text only views - Copy, recapture, cancel, download, share, settings, and expanded-view controls - Optional on-device translation on supported Chrome versions - Recognition progress and actionable error messages - Local capture history that can be disabled or deleted - Keyboard shortcut and context-menu access - 30 popular bundled OCR languages plus 39 Chrome on-device translation targets `Auto` currently defaults to English. Choose a language explicitly for better accuracy on non-English text. Privacy Selected image pixels and recognized text stay on your device during OCR. CopyCatch does not require an account and does not transmit captures to an OCR server. Text leaves the extension only when you explicitly use Share and choose a destination. Important limitations OCR accuracy depends on image resolution, contrast, font, language, rotation, and compression. Always review recognized text before using it for legal, medical, financial, or other consequential purposes. Chrome internal pages and other browser-restricted pages cannot be captured by extensions. Claims policy Do not publish an accuracy percentage in this listing unless the exact benchmark version, sample count, language, image categories, and scoring method are published with it. Never use “error-free,” “perfect,” “without mistakes,” or “works on everything.”
