With this licensing model, you subscribe to Captivate on a monthly basis. This means that you pay a certain amount each month to keep using Captivate. The main benefit of the subscription model is that you automatically get all the updates as they are released. The subscription model is the best way to ensure that you always have access to the latest version of Captivate. Note that the subscription is just another licensing model; the software itself is identical to the perpetual licensing model.
More information on the various Captivate licensing models can be found at http://www.adobe.com/products/captivate/buying-guide.html.
Although the Captivate subscription model is very similar to the way Adobe Creative Cloud works, Captivate is–at the time of writing–not a part of the Creative Cloud.
Captivate and the Creative Cloud
If you already have a Creative Cloud subscription, you'll need another subscription for Adobe Captivate.
