Kobo Notes is a note extractor for Kobo eReaders. After uploading your data via the web application at www.kobonotes.com, you can access your Highlights and Annotations at any time and from any device.
With Kobo Notes, you don't need programming skills and/or install anything on your computer. Also, unlike other tools for note extraction, your notes will be organized by date of creation (which I believe should be the natural way of presenting your notes, and not some semi-random order). Lastly, as this is a web application, you can access your data from any device and read them whenever you want (if you have an account).
