Wink is a Tutorial and Presentation creation software, primarily aimed at creating tutorials on how to use software (like a tutor for MS-Word/Excel etc). Using Wink you can capture screenshots of your software, use images that you already have, type-in explanations for each step, create a navigation sequence complete with buttons, delays, titles etc and create a highly effective tutorial for your users.
Wink is aimed at a wide array of users - software developers who need to document how to use their software, documentation creators and all other users who want to share tips and tricks of their favourite software with others. For eg: people who do video editing tutorials can use Wink to create a more effective tutorial for showing exactly how to do an effect/edit.
