Shrinking, but visits without Grammarly are up 29% on a year ago.

Over two years, visits went from 27M in November 2024 to a high of 67M in February 2026, and stand at 48M in October 2026. Much of the year’s change is one site, Grammarly, which is why I also look at the market without it.

Miles explains

I only call a market growing when visits and name searches agree. Here visits are up and name searches are down, so they don’t agree yet.

“ai detector” is searched about 13,600,000 times a month worldwide, 37% of it in the US.

Google Trends barely registered “ai detector” until April 2023; interest then climbed to its peak in October 2025. Americans make 37% of the searches but only 25.1% of the visits, because the big sites also draw heavily from India, United Kingdom and Canada.

Miles explains

Google Trends shows direction, not volume. Interest is lower than a year ago, and I only trust that when the visits move the same way.

Fewer visits than a year ago only because of Grammarly, fewer people searching by name, and the next six months look flat.

The fastest growers over the year, MyDetector, Pangram and Solvely, each grew several times over, usually from a small base. The losers, led by Smodin, lost most of their search visits (-77%).

Miles explains

Huge percentages like MyDetector’s +2029% usually mean one site won a big Google ranking from a small start. I watch whether it holds the next month.

I expect November 2026 to be about the same as October 2026, and the next six months to look flat.

The forecast carries the level of recent months forward, not the trend line, because that version missed least when tested on past months. November is usually a busier month than average for searches, but the calendar did not improve the forecast, so it is left out.

Read the range, not the single number: tested on the last 6 months, my method landed inside its range 4 times.

The most visited is Grammarly, with 22 million visits a month, 46% of all visits.

Grammarly and ZeroGPT together hold 67% of all visits. Below the top five the market is long and thin: the other 22 sites share 12.1%.

Miles explains

Grammarly alone has 46% of all visits. That’s a big lead, but one Google update can close it fast.

Yes. Every number on these pages comes from two CSV files, free to download.

sites.csv has one row per site: its Google US position for “ai detector”, Tranco rank, Chrome UX tier, visits from Google worldwide and in the US, name searches, Domain Rating and referring domains, with the month each figure covers. market.csv has the monthly totals across the tracked sites: visits worldwide and in the US, name searches and referring domains. Blanks mean the source had no figure, never zero.
