What you can do in Newsedge on the web
Headline or URL in, markets out
Type a headline or paste an article link. Newsedge unpacks the URL slug back into words, runs it against the bundled index and ranks what it finds.
Every match cites its trigger
No black box: each result shows the exact keyword that fired — “fed”, “march madness”, “ukraine” — so you can tell a real hit from a coincidence.
Relevance you can reason about
A long, specific phrase outranks a short generic one, so “march madness” beats “cut” and the ranking makes sense at a glance.
Saved stories that re-run themselves
Keep the headlines you came back to. Every time you open one, the lookup runs again and shows the current match list, the strongest trigger and the beats it touches.
The whole index is browsable
All 17 markets grouped by beat with every trigger keyword on show, plus which of your saved stories hit each one — and a CSV export of the lot.
Honest about misses
When nothing in the catalog reacts, Newsedge says so instead of inventing a match. The example story that matches nothing ships with the sample data.
