There are three main components to Spark: Page, Post and Video. Those tools were formerly the standalone Slate, Post and Voice; Adobe is basically branding them under Spark and giving them a bit more power under the hood.
We don't shill.

With Page, you can create slick “magazine style” landing pages, which are hosted by Adobe. In use, it’s a bit like a pared-down Squarespace or Weebly, which is likely a better option for Adobe’s target audience.
Spark Post should be a bit more familiar to the average user. With it, you can take images and overlay text for use as a flyer for a store or social media.
Post is easy to use, but almost endlessly powerful. You can choose from several different fonts, and use your own images — or search for one under a Creative Commons license. It even knows the preferred graphic size for social mediums like Twitter, Pinterest, Facebook and Instagram.
Editing is a snap; Adobe has packed in a bunch of presets for styles, fonts and color schemes you can use. Once you’re done editing, Adobe hosts your Post, and makes a link available for sharing to social media. If you like, Posts can be downloaded.
Video is a lot like Post, but lets you overlay your voice as well. There are also some static icons you can choose from, which flow into a video with a bit of animation. If you’ve ever been wowed by a startups launch video for an app or service, Video lets you duplicate that effort for your own business or non-profit.
Spark’s suite of tools will be available today for iOS and the Web.
