Move over Siri, here comes Indigo for Windows Phone 8 devices. Indigo is a cloud-based, cross-platform, personal assistant app developed by Artifical Solutions, a company specializing in natural-language processing. Indigo adheres to spoken commands and questions. Text messages can be converted from voice into text and sent, all through voice command. Existing apps such as contacts, weather, maps, calendars and alarms can be managed as well. With social media integration, Facebook can be updated and tweets can be sent. Indigo also works with Yelp to find the best restaurants and utilizes Google or Bing to make searches. With Indigo's cloud-based and cross-platform design, users can easily switch from one device to another. Look for its release in the next few weeks.
