Copyfish vs GNU Ocrad
Both stand on ocr software. Which one you can start free with, which one lets you read the code, and what each costs once you pay.
Free plan ExtensionLinuxMac+1
Choose Copyfish if you want free OCR in a browser, or desktop capture with XModules2, and value an offline mode or translation integrations. Look elsewhere if offline OCR's reduced language coverage and accuracy are not suitable, or if you do not want to use the required desktop module for local OCR and desktop capture.

GNU Ocrad offers command-line and backend OCR with layout analysis and configurable output. Its documented sensitivity to character defects and research-project status are worth considering for production use.
