Backroom allows people to work together in a Room to discuss and propose a solution to a specific problem they are interested in solving. The goal is to leverage the power of the internet and build on the concept of social media to bring people together from any walk of life and give them the tools to not only communicate with each other, but also work together to create solutions to the problems facing society. To do this, Backroom uses ChatGPT to analyze the conversation between Room participants to suggest a solution to the problem being discussed, helping break the ice and propose an unbiased solution driven by real conversations. Others will then be able to read the solution created by the participants along with the conversation that took place to add context and see the reasoning behind the solution.
