The Watson Developer Cloud is a collection of APIs that enables developers to add cognitive capabilities to their applications. All of the APIs are available for use by applications built in Bluemix.

Specifically, The APIs offer cognitive capabilities in the following four main categories:

  • Language - use unstructured bodies of text to retrieve insights from that text. Insights can span a wide range, from the personality traits of the author who created the content to specific details on what the content is about and what it may be related to.

  • Speech - interact with your users in many different languages using speech-to-text and text-to-speech.

  • Vision - understand the world around you by retrieving insights on the users who created certain images.

  • Data Insight - access data pipelines and help make decisions on competing criteria.
