Collective intelligence (CI) is the enhanced capacity that emerges when people collaborate—combining ideas, data, or knowledge with tools and methods—toward a shared goal, such as solving a problem, making a decision, or generating new insight.

In the context of research and policy, CI helps tackle complex and multidimensional challenges by mobilizing distributed expertise and facilitating effective learning and decision-making. Whether it involves a small group of experts or large-scale public participation, CI relies on carefully chosen methods to guide collaboration, analysis, and action.

This toolkit is designed to help you explore those methods and choose the ones best suited to your CI project. For guidance on how to design a collective intelligence project beyond the choice of methods, you can refer to the CI Playbook developed by Nesta.

Keep in mind that this toolkit is designed to evolve over time as we test new use cases, refine categories, and enhance its usability. We welcome your feedback and ideas to help shape future versions.
