Crawls the web for Bing Search and, per Microsoft, feeds Copilot and Bing Chat surfaces. Microsoft documents a separate opt-out from generative-AI training use via the noarchive robots meta tag or X-Robots-Tag header rather than a distinct Copilot user agent; no Copilot-specific crawler token is named in Microsoft's public documentation as of 2026-09-13.
