OneMind - An anonymous consensus tool for any group of people

OneMind looks like a groupchat, but it is actually a system designed to get multiple people to converge on a single idea. Using timed rounds, participants propose and rate each other's ideas. Quality results are ensured through a two-round requirement, where an idea has to win two consecutive rounds to avoid flukes. This is basically an idea competition. Anonymous, so participants can feel safe to speak their mind.
