Why install Sophia

Turn your website from a brochure into a 24/7 lead-conversion engine.

Most marketing sites convert 1-3% of visitor traffic into leads — the rest bounce when they can't find what they want. Sophia closes that gap. She greets every visitor, answers their questions instantly from your own product pages and docs, captures email + company + intent, and books a demo on your Cal.com — all in the same conversation.

What Sophia does, in plain English

Sophia turns your website from a brochure into a conversion engine. She greets every visitor, answers their questions instantly from your own product pages and docs (no more bounces because the answer wasn't on the page), captures their email + company + intent, and books a demo on your Cal.com — all in the same conversation. Customers using Sophia typically see 2-4x lift in marketing-qualified leads from the same traffic. She works as both an AI SDR (lead capture + outreach) and a Knowledge Agent (your website's brain) — Sophia auto-summarizes your homepage and key pages on install so she's productive in minutes, then you can deepen her knowledge by uploading PDFs, decks, wiki docs, or Skill.md files in the admin. Install once via a <script> tag, or one-click from Vercel / Wix / AWS / GCP / Azure marketplaces. Multi-tenant from day one: per-site branding, per-site knowledge base, lead capture into HubSpot, follow-up emails from your own Gmail, demo bookings on your Cal.com, real-time alerts to your Slack. Claude Sonnet LLM is bundled on Agent21's API key — no Anthropic account needed, no per-token costs. 7-day free trial, then $29.99/mo flat for unlimited messages.

Guardrails & security

Every Sophia conversation is governed end-to-end.

  • Agent Firewall — pre-LLM input scan blocks prompt injection + credential leaks
  • DefenseClaw — pre-tool-call scan blocks risky tool args before execution
  • TrustModel governance — continuous third-party audit + public TrustScore
  • Per-tenant data isolation — RLS on every table, KB scoped per site
  • Anti-impersonation — Sophia never speaks for any company other than the current tenant
  • Hard-rule enforcement — no fabricated pricing, no fabricated features, no commitments to future delivery dates
  • Voice-safe output — no markdown bold / italic / em-dashes that TTS verbalizes oddly
  • Escalation path — legal / procurement / hostile / unknown questions routed to a human
  • Session-scoped tools — Sophia can only act on the current visitor's session, never cross sessions
  • Audit trail — every tool call + every safety verdict logged to sophia_messages.agp_decisions

How It Works

Triggers: This agent activates when you mention: "website chat", "demo booking", "lead capture", "visitor question", "inbound", "support"

Output: Returns a text response

Sample Output
Hi! XSpan is an Autonomous Preventive Health Platform — it tracks 100+ biomarkers and acts on your behalf (books labs, adjusts plans). I just emailed you our security one-pager, and I have time on the team's calendar Thursday at 2pm or Friday at 11am ET — which works?

Safety Constraints

  • Never speak for a company other than the current tenant
  • Never quote prices outside what's in the KB / published pricing pages
  • Always cite the KB page when referencing wiki content
  • Escalate to a human for legal / procurement / DPA questions
  • Agent Firewall enforced — no external action without Human Co-Pilot approval
