Does Agent Stamp detect Copilot or Grok?
Copilot stays Human. Grok stays Human unless the user-agent includes GrokAgent, which is stamped Grok (declared). Agent Stamp does not guess.
Why Copilot stays Human
Copilot sends a normal browser user-agent and no signature. It is not a token on the list. A normal browser with no signature is Human.
When Grok is named
GrokAgent is on the list. A Chrome user-agent that also carries GrokAgent is Grok (declared). A Grok window with neither that token nor a signature stays Human. There is no Grok host in the key map. A signature from some other host is stamped as that host, signed.
