This extension allows users to connect to OCR  (optical character recognition) to call feature types including Read Image, Read PDF, Read MultiFrame Image and Save PDF.

Advanced OCR extension works in optimum conditions and does the job with improved stability and accuracy in any conditions; this allows users to detect and read text from imperfectly scanned Images or PDFs.

There are advanced features available for getting more accurate output e.g. enhancing low-quality documents. OCR uses artificial intelligence for text search and its recognition of images; this extension finds templates in pixels, letters, words, and sentences.


When the OCR Extension is installed, the Toolbox will be updated for Flow models.

See OCR Commands for the full description.
