"We are planning an iOS and Android app so people have extra privacy and to be HIPAA-compliant. There’s a good reason to keep it with text and to NOT do it in voice. You cannot see a negative thought in voice, but in a text chatbot you write it out and this externalization helps you overcome it. Messenger was a great launch platform — they make it easy to create and launch a bot. Users loved our prototypes there and we decided to launch there as it was easy."
