Growing.

Over two years, visits went from 81M in November 2024 to a high of 998M in October 2026, and stand at 998M in October 2026. Much of the year’s change is one site, ChatGPT, which is why I also look at the market without it.

October 2026, 998M visits

Miles explains

I only call a market growing when visits and name searches agree. Here visits are up and name searches are up, so they agree.

“ai pdf reader” is searched about 2,900 times a month worldwide, 25% of it in the US.

Google Trends barely registered “ai pdf reader” until August 2023; interest then climbed to its peak in May 2026. Americans make 25% of the searches but only 7.7% of the visits, because the big sites also draw heavily from India, Germany 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.

More visits than a year ago, more people searching by name, and the next six months look like growth.

The fastest growers over the year, ChatGPT, Claude and HiPDF, grew fastest, mostly from a smaller base. The losers, led by ChatDOC, lost most of their search visits (-94%).

Miles explains

Huge percentages like ChatGPT’s +320% 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 4% more than October 2026, and the next six months to look up.

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 5 times.

The most visited is ChatGPT, with 919 million visits a month, 92% of all visits.

ChatGPT and Smallpdf together hold 96% of all visits. Below the top five the market is long and thin: the other 10 sites share 0.3%.

Miles explains

ChatGPT alone has 92% of all visits. That’s a big lead, but one Google update can close it fast.
