Image Reader (OCR) is an add-on for Microsoft Edge. It allows users to effortlessly extract text from any image using an open-source OCR engine, Tesseract. This extension uses a JavaScript library to implement the renowned Tesseract OCR Engine, originally in C and C++. The add-on simplifies the extraction procedure - simply load your image and the OCR language (default set to English). Note that the language data required for OCR operation is fetched from a specific GitHub repository as it is too large to be included in the extension package.

Image Reader (OCR) extension helps you easily get words out of any image. It uses an open-source OCR library called Tesseract. Tesseract.js is an open-source JavaScript library and is made via an Emscripten port of the famous Tesseract OCR Engine written in C and C++. Please visit (https://github.com/naptha/tesseract.js) to get more info.
To work with this addon, simply open the addon's interface and load your image via the file selector (top section). Before using the addon, please make sure to select the appropriate OCR language. Default OCR language is set to English.
Note: this addon uses the "https://github.com/naptha/tessdata/tree/gh-pages/" GitHub repo to fetch language data required for the OCR operation. Language data packs are very large and cannot be included in the addon package.
It's using tesseract but the trained data-model I am looking for was jpn_vert (it supports only jpn); and secondly, unlike other OCR extensions, this does not OCR from browser, it makes the user copy image-file to its window. (If that was the case, it's best/better to use Windows Snipping Tool with "Text Action" feature, it does incredible OCR of mixed languages and in pretty decent time)
