Personalized signal intelligence
Define your alert thresholds in plain English. We scan any website, feed, or topic you care about twice daily and notify you only when something actually crosses your line — not just when it's topically related.
Examples of what people monitor
"Notify me when a nuclear weapon is detonated anywhere in the world."
"Alert me while crude oil stays above $100 per barrel."
"Tell me when my favorite band announces a show within 50 miles of my city."
"Alert me when my neighborhood association posts about zoning or permits."
Three steps, no technical setup required.
Write in plain English what should trigger your alert. No boolean syntax, no keyword lists — just say what you mean.
Twice a day we fetch content from your sources — news, blogs, community sites, any RSS feed — extract structured data, and run everything against your thresholds.
No noise. No daily digest of vaguely related articles. You're notified only when your specific threshold is actually crossed.
Google Alerts sends you anything mentioning your keywords. Threshold Signal only fires when something is actually true.
Perfect for discrete events. You get one notification when the threshold is first crossed — not again every day there's another article about it.
Perfect for ongoing conditions. You're alerted for every matching article while the threshold remains true — so you don't miss new developments.
