Google does not run a separate crawler for AI Overviews. Googlebot does the fetching, and Google-Extended is a robots.txt control over how that content is used for Gemini. WriteWorks tracks Googlebot's crawl of your pages next to every other AI crawler, so Google's activity sits in the same picture.

One crawler, one control token, several AI surfaces.
Many teams expect to see a Google-Extended crawler in their logs. It is a robots.txt product token, not a separate bot: Google's existing crawlers fetch the page, and the token controls whether that content may be used for Gemini models and grounding.
AI Overviews are built on Google Search's index, which Googlebot crawls. Blocking Googlebot removes you from search results as well as the overview.
Search Console reports Googlebot's crawl in its own interface, while GPTBot, ClaudeBot and PerplexityBot sit in raw logs. Comparing Google with the other engines means stitching sources together.
Content written to rank in blue links rarely carries the structure an assistant needs to quote it directly.
Report what arrives, classify it, compare it.
WriteWorks identifies Googlebot requests from your server or CDN logs, resolves them to Google and classifies them as AI Indexing, so Google's crawl is compared directly with OpenAI, Anthropic, Perplexity and the rest.
Google-Extended is in the WriteWorks registry, classified as AI Training, so any request identifying itself that way is labelled. In practice its effect is set in robots.txt rather than seen as separate traffic, and WriteWorks reports what actually arrives.
Bot signals map Google crawler activity to Gemini and list pages crawled in the last 7 days that Gemini has not cited yet, alongside the same check for the other engines.
From invisibility to category dominance across every major answer engine.
