Shrinking.

Over two years, visits went from 19M in November 2024 to a high of 38M in January 2026, and stand at 24M 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 down and name searches are down, so they agree.

“ai paper checker” is searched about 6,600 times a month worldwide, 82% of it in the US.

Google Trends barely registered “ai paper checker” until March 2023; interest then climbed to its peak in April 2026. Americans make 82% of the searches but only 22.8% of the visits, because the big sites also draw heavily from India, United Kingdom and Canada.

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, fewer people searching by name, and the next six months look like a slide.

The losers, led by Smodin, lost most of their search visits (-77%).

Decopy AI -26%

Miles explains

Huge percentages like Sapling’s +15% 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 down.

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.

Expected in November 2026

Miles explains

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, 90% of all visits.

Grammarly and Sapling together hold 94% of all visits. Below the top five the market is long and thin: the other 1 sites share 0.5%.

Miles explains

Grammarly alone has 90% of all visits. That’s a big lead, but one Google update can close it fast.
