OCR services can be used on your photos, but they are not fully automated yet. Here are some links to OCR tools you can experiment with.

Automate OCR with the Any Vision Lightroom Plugin! Read my blog post here.

Microsoft Cognitive Services: Computer Vision API – This is the one I demonstrate in the book. You can scroll down the page to “read text in images” and you’ll see an opportunity to upload a file. The site will display any text it finds in the image.

Adobe Acrobat DC – OCR is now included in Adobe Acrobat. It’s pretty cool for making edits to a PDF, but it does not do a great job stringing text together logically.
