In November 2013, I began working with members of the original team behind Skype on a new secure messenger called Wire.
For details, see the December 2014 launch post: Great conversations.
Text appears in the user interface (or “UI”) in button names, menu labels, application settings, and dialogs as well as the “microcopy” in notification banners, headings and small print, navigation, and error messages.
For Wire, I maintained these user interface strings directly in open-source repositories on GitHub for each application, including:
Tone of Voice
I also developed the Wire writing guidelines to help authors create clear and consistent content that speaks with a Wire voice and follows house style.
