The answer▲ Growing

Visits, year on year, without ChatGPT

Visits, last six months

Name searches vs October 2025
+6.3%

Every month I add up the Google visits to the 15 AI PDF reader sites I track (DataForSEO estimates) and how often people in the US search for them by name (Google Ads). In October 2026 they got about 998 million visits. Much of the year’s change is one site, ChatGPT; without it, visits are up 20% on a year ago.

The total hides very different stories: one site grew 320% in a year while another lost 94% of its visits. See who grew and who shrank, the visits month by month and the name searches, plus what I expect for November 2026.

Miles explains

More visits than a year ago means new people are still finding AI PDF reader sites through Google. Most of that growth is one site, ChatGPT; without it, visits are up 20% on a year ago.

2.Are people searching for AI PDF reader sites by name?

Up 6% on October 2025; 133M name searches a month in the US

Yes, more than before. People in the US searched Google for the names of the counted AI PDF reader sites 133,273,550 times in September 2026, 6% more searches than in October 2025. Someone who searches a site’s name already knows it, so this is the clearest sign of people coming back on purpose. The term “ai pdf reader” itself gets about 720 US searches a month (Google Ads, 12-month average).

Miles explains

Name searches are up 6%. This number does not change when Google reshuffles its results, so it is the most reliable sign of growth on this page.

The five most-visited sites hold 99.7% of all visits; the ten most-visited hold 100%

The five most-visited AI PDF reader sites get 99.7% of all visits, so one of them winning or losing a big Google ranking moves the whole total. Fastest grower over the year: ChatGPT, from 218,778,485 to 918,686,520 visits (+320%). Steepest fall: ChatDOC, from 60,120 to 3,754 visits (-94%).
