Cogitai Continua extends the capabilities of IFTTT. If you have hooked up your smart home devices and services (like Twitter) to IFTTT as a way of automating your life, you can easily feed all that data to Continua with a Tell Applet. Then you can use that data to trigger useful followup actions, like sending you a notification on your smart phone!
Continua remembers data about your habits. You can ask it questions about your habits and it will provide you with answers. For example, you can ask questions about time sensitive events and receive notifications about the answers.
