3Square is a Decision OS that captures, reviews and retrieves the decisions teams make across mixed human and AI workflows. It is built for engineering leaders folding AI agents into their teams. The differentiator is capturing decision context as a byproduct of existing work, so nothing extra has to be documented by hand.
