The DAISY Consortium is delighted to bring you the new Ace by DAISY App. Many of you will be familiar with the command line tool which has proved revolutionary for accessibility checking within EPUB workflows and this new desktop version builds on test version released a couple of months ago to make testing EPUB files from your desktop an even easier process.

Ace by DAISY helps you to ensure your EPUB content conforms with the EPUB Accessibility 1.0 specification, allowing all readers to access and enjoy your content irrespective of print disabilities or access requirements. The Ace App is designed to allow you to quickly test EPUB files through a familiar graphical user interface and highlight any issues which need to be addressed. Users will still need some understanding of the EPUB specification and accessibility requirements in order to resolve any problems found, but to make that process easier the Ace App is integrated with the DAISY Accessible Publishing Knowledge Base proving quick links to the relevant reference in this essential resource.

The Ace App is not intended to replace the command line tool, which remains the ideal solution for those wishing to test multiple documents or to integrate the testing process directly into production workflows. Technically the testing process taking place behind the scenes is identical on both the Ace by DAISY command line tool and the Ace App, so this is simply an easier way for some users to access the same process.
