Of course, you can capture highlights of Kindle books to Ikes.
Nowadays, many people read on their Kindle. With the iOS Kindle app, you can send your highlights to Ikes without leaving the book you are reading.
It's very easy to do. First, tap the highlight to open the menu. When the share screen opens, simply select the text and choose Ikes from the share menu, just like any other app.
If you are using the Mac version of Ikes, you can make the process a bit more efficient.
Amazon provides "Your Notes and Highlights" which is a web page that shows you a list of highlighted sections on your Kindle, and if you open this page in Safari and turn on the share feature, you can quickly save your highlights to Ikes.
