Repository of problems worth solving
World Solve is a public institutional repository for identifying real unresolved problems across science, society, health, governance, economics, and local systems. Each entry is intended to be citable, inspectable, and actionable.
Publicly citable
Every problem has a stable citation code for reference and discussion.
Filtered by relevance
Search by category, geography, status, and keywords.
Builder-oriented
Use the repository to find startup ideas, policy leads, and research agendas.

AI language models have been shown to generate plausible-sounding but entirely fictional legal citations, and this has already caused real problems in actual court filings. Building reliable safeguards against this in legal workflows remains an unresolved and urgent challenge.

Recommendation systems tend to show users more of what they already agree with because that content performs better for engagement, gradually narrowing exposure to differing viewpoints. Correcting for this without reducing relevance remains an unresolved design challenge.

Developers often only discover accessibility problems after a product has already launched, since automated tools can't yet catch every meaningful barrier during the build process itself. Building this detection earlier into development workflows remains incomplete.

A few seconds of someone's voice is now enough to generate convincing fake audio of them saying anything, and current detection tools often fail to catch high-quality fakes in real time. This is already being used for financial scams targeting families and businesses.

Penguin, krill, and seabird populations are already shifting or declining as habitats change and food webs reorganise. Long-term ecological monitoring and ecosystem-modelling platforms are needed to guide conservation.

Middlemen often exploit price information gaps, paying farmers far below market rates for crops. Simple SMS or app-based price-transparency platforms have already shown strong impact where deployed.

Some medications carry a risk of gradual liver damage that often goes undetected until routine screening or symptoms reveal significant harm has already occurred. More sensitive, earlier detection methods remain an unmet need.
