Harmonica is an AI-powered tool for collective sensemaking. It's using GPT, but in multiplayer mode and in combination with advanced facilitation prompts based on popular frameworks like Sociocracy, Liberating Structures, TRIZ, Delphi method, etc. It allows teams and communities to run async workshops and collectively create artifacts (such as roadmaps, canvases, OKRs) in a matter of minutes instead of weeks.

In other words, Harmonica can be viewed as a post-GPT alternative to forums, surveys and workshops. On the other hand, it offers a much better UX than old deliberative tools like Pol.is
