Tessa - OCR extracts text from your image or PDF documents, processing each page multiple times, to optimise recognition, so that the time you spend in proofreading and correcting mistakes is minimised.
The editing tools available in the app allow you to modify pages before they are processed, so that you can whiten out un-needed areas and limit recognition to a specific part of your page
While the basic version of the app limits recognition to one page at a time, a single in-app upgrade to premium, unlocks the ability to process multiple pages in a single go. Upgrading to premium also removes ads, and unlocks functionality to edit the output text in the app itself, prior to saving.
Note: While the software is classified as free, it offers in-App Purchases.
