The answer▼ Shrinkingbut visits without Lucidchart are up 3.1% on a year ago
- Visits, year on year, without Lucidchart
- +3.1%
- Visits, last six months
- -17%
- Name searches vs October 2025
- -16%
Every month I add up the Google visits to the 18 AI diagram generator 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 16 million visits. Much of the year’s change is one site, Lucidchart; without it, visits are up 3% on a year ago.
The total hides very different stories: one site grew 139% in a year while another lost 99% 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.

1.Are more people visiting AI diagram generator sites than a year ago?
Down 6% on a year ago; down 4% on September 2026
Only because of Lucidchart. The 18 tracked AI diagram generator sites got 15,835,825 visits from Google search in October 2026. That is 6% fewer visits than in October 2025, or 3% more without Lucidchart, and 4% fewer visits than in September 2026.
The highest month of the last two years was December 2024, with 20,208,996 visits; October 2026 is 22% below it. In the US, visits were 1,929,595, down 13% on a year ago.

Miles explains
Visits are lower than a year ago and lower than in September 2026, so the fall is still going. Name searches (-16%) and Google Trends interest in the term (-78%) fell too, so people are less interested, not just finding these sites less often.
2.Are people searching for AI diagram generator sites by name?
Down 16% on October 2025; 854K name searches a month in the US
Fewer than before. People in the US searched Google for the names of the counted AI diagram generator sites 853,790 times in September 2026, 16% fewer 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 diagram generator” itself gets about 720 US searches a month (Google Ads, 12-month average).

Miles explains
Name searches are down, so fewer people are coming back on purpose. Better Google rankings will not fix that.
3.Which AI diagram generator sites grew, and which shrank?
The five most-visited sites hold 92.8% of all visits; the ten most-visited hold 98.4%
The five most-visited AI diagram generator sites get 92.8% of all visits, so one of them winning or losing a big Google ranking moves the whole total. Fastest grower over the year: ProcessOn, from 35,191 to 84,148 visits (+139%). Steepest fall: Lucidchart, from 1,493,450 to 18,516 visits (-99%).
