Traffic is the late signal
Visits show who clicked. They do not show the answers where you were left out. The free check shows whether assistants name you in the first place.

Questions people ask
Why anchor the regex with ^ and $?
GA4's "matches regex" must match the whole value. Anchoring also stops a pattern like chatgpt\.com from matching a look-alike such as notchatgpt.com.
Why do my AI visits look so small?
Many visits from assistants arrive with no referrer and land in Direct. Others come from apps. The numbers are a floor, not a total.
Can I separate Google's AI Overviews from normal search?
Not by referrer. Google's own channel definition leaves them out and counts them as organic search.
