Here’s how I read these two lines. They don’t show how many people search, only when interest rose and fell. Worldwide, it peaked in October 2025 and sits at 79 now, lower than a year ago. In the US it’s lower than a year ago, and the Google Ads numbers below tell the same story. When you see a sharp spike, think news story, not new customers. The baseline between the spikes is the demand I actually care about.

This is the number I’d plan with: September 2026 had 5,000,000 US searches, 33% fewer than in October 2025. Google Ads rounds these figures into steps, so a small move from one month to the next usually means nothing.

The biggest related search is “ai checker”, at 5,000,000 searches a month worldwide. Rising fastest next to it on Google Trends: “pangram ai detector”, “ai detector photo” and “ai detector image”. A sudden riser is usually news, not lasting demand.
