Zen Cortext

Zen Cortext is a GPL WordPress plugin that turns a page into an AI sales consultant for pre-sales qualification. Not a chat widget. The chat page IS the landing page where you send paid traffic.
The AI auto-learns from your WordPress content and delivers full-context responses. The complete knowledge base goes into every request, so the AI sees connections across your materials instead of isolated fragments.
Per-campaign personalization: UTM parameters and ad click IDs trigger different greetings, starter questions, and AI context. One URL works like dozens of specialized landing pages.
When the AI identifies a serious prospect, it pushes a notification to your team's phones via PWA. A team member joins the live conversation in seconds.
Built-in attribution tracks every conversation from ad click to deal at the database level.
No subscription. No seat fees. Pay Anthropic directly via your own API key. About $1 per conversation.
Self-hosted. GPL licensed. Your database, your API k
