Overview

Product summary

Review the store description, core capabilities, and common use cases.

This extension adds a toolbar button to your browser to perform OCR. When this action button is pressed, it allows the user to select a region in the currently active window. The extension captures the area and tries to recognize text inside this region using the internal powerful OCR engine (Tesseract engine). This extension uses the "tesseract.js" library that supports more than 100 languages, automatic text orientation, and script detection.

This extension loads the JS library on the page and removes it when you are done. This way, there is no long-term resource usage.

Engines:

Tesseract: Only extracts plain text from images and doesn't preserve formatting

IBM Granite-Docling: it can accurately interpret headings, lists, styles (bold, italics), tables, and mathematical equations.

Does not work at all. No matter what text or numbers and language I choose - getting only "loading language traineddata" message and nothing actually loads.

Couldn't get it to work, it was just stuck on "loading language traineddata" Maybe its because Im on Brave or something?
