AI host labels

The by AI host chart on /analytics + every per-agent caller breakdown groups requests into 87 buckets, derived from the User-Agent header. This page is the full reference — partner vendors can verify their UA gets classified correctly, and operators can read what each label means.

Mismatches? Crawlers (tagged ⚠ training/index below) are excluded from page-view counts so they don't inflate visitor stats. User-initiated browse buckets (Claude / ChatGPT / Perplexity / Grok / Gemini followed by (browse)) ARE counted — those are real per-message AI sessions, not training scrapes.

Missing a host?

If your AI host / agent platform sends a User-Agent that doesn't land in any of the buckets above, it'll show up as unknown on /analytics. File a PR with the UA pattern + label in app/call_log.py — or open an issue with a sample UA string and we'll add it.

Source of truth: app/call_log._UA_PATTERNS + _CALLER_KIND_LABELS. Every entry here is generated from those at request time, so it can never drift.
