A fully-featured, multi-persona chat app which lets you take full control of your privacy. Modeling Real-life Relationships and Interactions with Multiple Personas Personas are different aspects of our character that we choose to share with different people, e.g. to families, to friends, to co-workers, to strangers. OpusChat is a chat app which supports personas. In addition to the features one would expect from a chat app, you could create and use multiple personas in one seamless app. Each persona is seen by others as a completely different profile. You can customise how you present yourselves and manage each relationship. You could protect and control your privacy when messaging or calling contacts using different personas, as well as apply specific preferences for each persona.
