Help a human rights investigator turn scattered reports into evidence that holds up.
Tech partner

Much of the record that once existed is gone by the time a court needs it.
Human rights investigators working to international evidence standards (the UN's Berkeley Protocol) must corroborate incidents from fragmentary, disappearing sources — reports get deleted, outlets go offline, and single-source claims don't hold up before a tribunal.

What to build
Your Mission
Build an AI-powered solution that helps a human rights investigator turn scattered reports of an incident into evidence that holds up.
Your solution should corroborate an incident across independent sources, preserve the record before it disappears, and turn claims into a documented chain of evidence an investigator can stand behind. How you solve it is up to you. Exa gives you corroboration across independent sources, preserved content, and cited confidence for every claim; the rest is yours.

Scope
What Success Looks Like
There is no single right solution. You could take the problem in many directions — pick a specific user, a clear decision, and make that experience work well.
Tip:
Don't try to solve the whole problem at once. Pick a specific investigation stage, evidence type, or corroboration decision, then make that experience work well.

Requirements
Technical Challenge
Think about how your solution will corroborate an incident across independent sources — who reported it, when each account first appeared, and which details agree — attach citations and confidence levels that meet evidence standards, preserve full source content before it disappears, and keep watching for new reporting, witness accounts, and official responses long after the news cycle moves on. These are opportunities to explore, not requirements you need to satisfy all at once.
Tip:
Your solution doesn’t need to be production-ready. We welcome everything from early prototypes to fully working implementations and ambitious technical explorations.

Use of tech
Recommended Tools
Exa provides a web retrieval layer that might be useful here. Exa's `news` index and grounded search can corroborate an incident across independent sources with field-level citations and confidence scores, the Contents API preserves full text of source pages as they're found, and Monitors keep watching for new reporting, witness accounts, and official responses. Whether Exa fits your solution is up to you.
Tip:
Whether or not you use Exa in your solution is entirely up to you.

- Exa API / SDK to getting started
- Exa documentation for search and retrieval
