PDF OCR is a simple drag-and-drop utility that converts PDFs and images into text documents. It uses advanced OCR (optical character recognition) technology to extract the text of the PDF or image. This is particularly useful for dealing with PDFs and images that were created via a scan-to-PDF function in a scanner or photo copier. It uses the Tesseract engine to perform OCR, and currently supports over 20 languages for OCR.
Character Recognition is an Android app that allows the user to take a photo (or use existing image files on the device) and then apply the Tesseract OCR engine to extract the text in the photo. It is currently supporting English text, but other language support will be added in the future.
