How do I import highlights from physical or paper books?

If you have the Readwise iOS app or Android app installed, you can capture highlights from paper books using your phone's camera and optical character recognition (OCR). 

You can also use screenshots or other photos already stored in your phone's camera roll by selecting the photo gallery option in the bottom right-hand corner.

In addition to OCR, you can manually type up highlights into Readwise from the dashboard > Import > Freeform Input

Finally, you can add the titles of paper books you've read and audiobooks you've listened to as Supplemental Books to see popular highlights in your Daily Review.
