A living repository of problems worth solving.
World Solve is an institutional, citable repository of unsolved and solved problems across science, technology, economics, governance, and philosophy. We give independent researchers and entrepreneurs precise targets to work on next.
1. Explore & Filter
Search and filter across continents, categories, and tags to find precise problems matching your expertise.
2. Claim & Work
Mark problems you are actively working on, collaborate with peers, and build verified solutions.
3. Citable Records
Every problem gets a unique permanent citation ID (e.g. WS00042) for research papers and proposals.
