Tool Open source
OCR It is a Chrome and Firefox browser extension for extracting text from paginated document viewers, including scanned books, slide decks, PDFs, and embedded readers where text selection is unavailable. Users select a screen region, capture it with a hotkey, and append the locally generated OCR result to an ordered transcript; an automatic mode captures each page, advances the viewer, and stops when text repeats, paging fails, OCR fails, or a page limit is reached. OCR runs offline through a bundled Tesseract build without outbound requests, API calls, or image uploads. The extension crops, optionally enlarges, and converts the visible region to grayscale, queues OCR jobs serially, stores page text and verification thumbnails, flags consecutive duplicate pages, and exports the transcript as copied text or a TXT file with page separators. Page turning can use a picked screen point or keyboard event, including controls inside supported frames and shadow roots. It uses narrowly scoped browser permissions, relying on activeTab for single captures and requesting an additional site grant for automatic runs that persist across page loads or turn pages inside cross-origin iframes.

A browser extension that repeatedly OCRs a selected screen region when a hotkey is pressed and appends the results to a running transcript. It runs offline with bundled Tesseract and uses narrowly scoped permissions.
A Chrome extension that extracts text page by page from locked or paginated document viewers, including scanned books and PDFs without copy functionality. It runs OCR fully offline, can automatically advance pages, detect duplicates, and append results to a transcript.
