It uses the contents of your ideas to automatically build a visual map of your ideas. It will help you find new connections between things you are thinking about, and will spark new, outside-the-box ideas. The more you use it, the better it gets.
It analyzes text as you type to automatically tag your ideas and neatly organize them. If you have Siri, all it takes is speaking. Combined with a fluid UI that adjusts to you, Ideas is a pleasure to use.
Your ideas are available on all of your iCloud enabled devices. When you decide to realize an idea, you can export it to your favorite task management app*.
* currently supports exporting to Things and Omnifocus.
