Why Should I Use It?

Considerate

Considerate

Built for humans.
Conversations are moderated by a built in AI chat agent, providing pointers and suggestions during the meeting. Too loud? Talking too much? Not talking at all? c³ makes sure that everyone can take part in the discussion, and have their voices heard. All in a subtle and unintrusive way. Users are also able to record meetings, be it a brief moment, or the entire conversation.

Distraction

Distraction Free

Simple by design.
Nobody likes meetings, let alone setting one up. c³ was designed with simplicity in mind. A few clicks and you're in. More people can be invited via email invite. In the car or on the move? c³ will cut the video feed when it detects excessive movement. Removing any distractions that may otherwise take away from the meeting, or your commute.

Timeline

Timeline

Keep meetings brief and to the point.
c3’s timeline tracks who’s speaking when, letting everyone have a fair share of the conversation. Typed messages are pinned to the timeline so you can remember what you said and where. The timeline is sent to the participants of the meeting once it's over. It also saves when and what was typed in the chat box, displaying it on the timeline.

Our Vision

CS

“Considerate Computing Systems is based on decades of research; demonstrating the value of using appropriate social signals in responding to users.  We are working to make systems with contextually appropriate interactions.  These systems can improve productivity, reduce stress and improve lives. 

c³ was created to be a platform where everyone’s voice is heard. A system where users can focus on the conversation at hand, rather than the limitations surrounding the means of communication.”
