Duokan Kindle is 3rd party software for Amazon Kindle.
It is an alternative software for Amazon Kindles. As it utilizes the hardware differently, it differs from the Amazon software, and may be the only reader for reading/writing the target languages it supports which currently include Chinese and English. English menus have been added as of November 2010. Other languages are planned.
There are versions for Amazon Kindle 2, Kindle WiFi, Kindle 3G WiFi, Amazon Kindle 4, Amazon Kindle DX and Kindle DXG. This software does not remove the Kindle firmware which is still available. They will exist side by side and the user can choose which they wish to use.
This software supports PDF, DJVU, EPUB, CHM, TXT

"Our team are mainly composed by developers, a group of young people who gathered by reading hobby. Regard providing good Chinese reading service as our duty." (Quote team member)
