Is the AI caption generator market growing or shrinking?

The answer▼ Shrinking
- Visits, year on year
- -62%
- Visits, last six months
- -58%
- Name searches vs October 2025
- -36%
Every month I add up the Google visits to the 6 AI caption 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 2.1 million visits. Hootsuite alone takes 51.8% of the visits, so the totals mostly follow it. Without it, visits would be down 73.1% on a year ago instead of down 62.0%.
See who grew and who shrank, the visits month by month and the name searches, plus what I expect for November 2026.

Miles explains
Visits are lower than a year ago and lower than in September 2026, so the fall is still going. Name searches (-36%) and Google Trends interest in the term (-20%) fell too, so people are less interested, not just finding these sites less often.
2.Are people searching for AI caption generator sites by name?
Down 36% on October 2025; 70.4K name searches a month in the US
Fewer than before. People in the US searched Google for the names of the counted AI caption generator sites 70,380 times in September 2026, 36% 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 caption generator” itself gets about 1,600 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.
