Braina - Artificial Intelligence Software for Windows. Braina (Brain Artificial) is an intelligent personal assistant software for Windows PC that allows you to interact with your computer using voice commands in English language.
Braina makes it possible for you to control your computer using natural language commands and makes your life easier. Braina is not an average Siri or Cortana clone for PC. It isn't like a chat-bot, its priority is to be super functional and to help you in doing tasks. You can either type commands or speak to it and Braina will understand what you want to do.
