A lightweight collector logs which AI systems read your site — which one, how often, and whether it's a background crawler or a live fetch while someone's mid-question. The honest “is AI reading me yet?” signal — a discovery read, not a count of agents buying.
GPTBot, ChatGPT-User, ClaudeBot, Perplexity and more — identified and verified against published ranges, not spoofed.
The *-User agents are live fetches: a person is mid-conversation and the AI came to check you right then. That's a buying signal.
The trend over time is your timing-proof — evidence that agent traffic is arriving and growing, before it's obvious in revenue.
Scan free, then install the collector in one line.
