CopyFish

Copyfish is a free OCR browser extension that extracts text from images, videos and PDF files so you can copy, paste, search or translate it instead of retyping. It is useful for text trapped in screenshots, charts, diagrams, scanned documents, comics, error messages, memes and the frames of YouTube videos. The extension runs in Chrome, Edge and Firefox on Windows, Mac and Linux, and the versions are technically identical. You select an area of the page and it returns editable text, with the option to translate the result. A desktop capture feature, added by installing the free UI.Vision XModule2 native app, lets it read text from any region of your screen, including presentations, file menus, games and PDF files. It offers two OCR engines with different language coverage, including Arabic, Chinese, Japanese, Korean, Russian, Thai, Vietnamese and many Latin script languages. It is made by a9t9 software GmbH of Germany, the company behind the OCR.space API and the UI.Vision RPA tool. The vendor describes Copyfish as free OCR software and publishes no paid plan on its Copyfish page. The OCR.space site it is hosted on also offers a free online OCR service with a 5MB file size limit per document and a free OCR API. The listed address is the OCR.space home page rather than the Copyfish page, which sits at ocr.space/copyfish.
