An AI SDR that reads your site, talks to your visitors, and knows when to call you.
Zen Cortext is a WordPress plugin that replaces the landing page with a chat page — a single screen where your visitor lands directly in a conversation with an AI that knows your business, knows where they came from, and knows when to put a human in the room.
A live AI chat conversation — Zen Cortext rendering the page as the chat itself.

What it is
When someone clicks your Google Ad, your newsletter link, or an organic search result, they don't arrive at a wall of marketing copy with a "Contact Us" button buried at the bottom. They arrive in a conversation. The AI greets them in a way that matches the campaign they came from. They can tap a starter chip or just type. Dialogue begins immediately, on their terms.
This is not a widget. Not a popup. Not a corner-of-the-screen distraction. It's the page itself. The chat is the content.
The AI behaves like a senior consultant who has read every page of your business. It cites your real case studies, not generic talking points. It tells visitors when they're a bad fit — because that's worth more than a forced demo booking. When the conversation gets real, it pings a teammate on their phone, steps aside, and lets the human take it from there.
A senior consultant who has read every page of your business — and knows when to step aside for a human.
What it's made of
Nine pieces, designed to work as one system.
The chat page
A clean, distraction-free interface. This is the surface visitors land on — the only thing on screen.
The knowledge engine
Zen Cortext scans your WordPress content — pages, posts, case studies, FAQs — and runs each piece through Claude to classify and restructure it into a form the AI can actually reason with. Your existing site becomes the knowledge base. You never write FAQs again.
Knowledge Artifacts
Internal rules, pricing nuance, non-public case studies, edge cases you don't broadcast. Bring raw notes, or let the AI interview you in structured batches and write the document for you.
Attribution
Every chat is tied to its source — UTM, gclid, msclkid, fbc, fbp, referrer, landing page. This information lives with the conversation. You always know where the visitor came from.
Channel adaptation rules
The same chat page behaves differently depending on which campaign sent the visitor. You define the logic: this UTM gets this welcome, these starter chips, this contextual brief. One page becomes dozens of campaign-specific pages.
Seamless surveys
Attach qualification questions to any rule. The AI doesn't show a form — it weaves the questions into the conversation, emits clickable answer chips inline, and collects everything in the flow of dialogue. Completion rates forms can't touch.
Human handoff via mobile PWA
When the conversation matters, the AI tags a teammate. Their phone buzzes. They tap. They're in the chat. The AI shuts up. The human talks. If everyone's offline, the system quietly switches to lead capture.
Admin console
Every conversation is saved with full attribution. You see the entire chain: campaign → conversation → lead → closed deal.
Brainstorm mode
A private admin chat running on Claude Opus with extended thinking. It knows everything on your site and helps you draft new content, ad copy, page outlines, and find gaps in your library.
How it works
From your published content to a conversation that closes — without you writing a single FAQ.
Zen Cortext scans your WordPress site — pages, posts, case studies, any published content — and restructures it into a knowledge base the AI can reason with. No FAQ writing, no manual training. Your site is the training data.
When a visitor arrives at the chat page, the AI already knows your services, your pricing nuances, your past projects, and your limitations. It answers from your actual content, not from generic templates. If it doesn't know something, it says so and offers to connect a human.
For information that shouldn't be public — internal pricing rules, qualification criteria, unpublished case studies — there's a separate Knowledge Artifacts module. You either upload documents or run a structured interview where the AI asks you questions about your business and turns your answers into clean, organized knowledge.
Everything updates automatically when you publish new content on your site.
Your site is the training data. Publish content; the AI learns it.
Why it isn't just another AI chatbot
The category is saturated with widgets that pop up in the corner, ask "Hi, how can I help?", and frustrate the visitor within ten seconds. Zen Cortext is a different kind of thing.
It's a page, not a widget
Attention isn't split between marketing copy and a tiny chat window in the corner. The visitor came to talk; they talk.
The knowledge base builds itself
Every other platform expects you to sit down and write FAQs. We read your site instead.
Adapts to ad campaigns out of the box
Most chatbots are one-size-fits-all. Zen Cortext changes its first message, its starter chips, and its operating context based on where the visitor came from. Your ad budget stops dying on generic landing pages.
Surveys live inside conversations
No forms after the chat. Qualification happens in flow.
Human handoff is real and fast
Push notifications to your team's phones via PWA — not "we'll forward this to Slack and someone might see it tomorrow."
No subscription
You pay Anthropic directly for tokens. A typical conversation costs around a dollar. You're not paying for seats, features, or platform access — you're paying for actual conversations.
You own it
GPL plugin, your WordPress install, your database, your API key. Nobody can turn it off, raise the price, or lock you out.
The problems it solves
Problem
Paid traffic dies on landing pages
You're spending $5–15 per click. Out of every 100 visitors, two will start a conversation. The other 98 leave without a word — and you have no idea what they were looking for.
When the chat is the landing page, the conversation starts before the visitor decides whether they care. The AI speaks first. The starter chips name the most likely questions. The barrier collapses.
Problem
Ad creative and landing pages drift apart
You wrote 20 ad variants targeting different problems, but they all point to the same generic page. Someone clicks "Migrate from Magento" and ends up reading "We do web development." The thread is broken; the trust is gone.
Zen Cortext fixes this at the page level. The Magento ad lands on a page that opens with "Heard you're on Magento — what's hurting?", your migration case studies already loaded into context. One technical page does the job of dozens of campaign landings.
Problem
Qualification forms have miserable completion rates
To know whether a conversation deserves a phone call, you need five to seven facts about the lead — platform, scale, budget, timeline, decision-maker. Put that in a form and half your visitors quit by the third field.
The AI runs the same interview conversationally, with clickable answers. Visitors don't feel they're filling a form. Completion jumps by an order of magnitude.
Problem
Attribution stops at the click
Google Ads tells you which campaigns produced clicks and form submissions. It can't tell you which campaigns produced conversations — because conversations weren't measurable until now.
Zen Cortext stores every chat with its source. You see the chain end-to-end: campaign "magento-migration" → 47 conversations → 12 call requests → 3 closed deals worth $X. Closed-loop attribution from click to revenue.
Problem
Traffic arrives when nobody's there
Leads come in at 11pm Saturday and 6am Wednesday. A contact form means "we'll get back to you," which by Monday morning is "I forgot I wrote that company."
The AI runs 24/7. When your team is online, it routes serious conversations to phones via push. When everyone is offline, it captures contact details gracefully and promises a reply.
Problem
First-touch conversations burn out your team
Fifty repetitions a day of "tell me about your services," "what does it cost," "do you do X." A junior SDR at $40k a year burns out in six months.
The AI handles the first round. By the time a human is pulled in, the task is scoped, the budget is named, the timeline is on the table.
Problem
Knowledge bases rot
Traditional chatbots want you to write and maintain 200 FAQ pairs. Nobody does it. The bots degrade.
Zen Cortext reads your site. You publish a new case study; it's in the AI's knowledge immediately. You maintain one source of truth — your site — and the plugin learns from it.
Why it actually works
A handful of architectural decisions, taken together, produce the result.
Full knowledge base, every conversation
The AI receives your full knowledge base in every conversation — not a retrieval-augmented sample. This costs more in tokens but produces a fundamentally different conversation: the model sees connections between your materials, not isolated fragments. Fewer hallucinations, smarter transitions between topics.
A model that can actually hold a conversation
It runs on Claude, which in 2025 crossed the threshold where AI can genuinely hold a consultative conversation. Earlier chatbots were bad not because of their design but because the models underneath were too weak. This is a different generation of tool.
Attribution lives in the schema
Attribution lives in the database schema, not in a "GA4 integration." Every conversation is born knowing its source. The connection works without configuration.
Mobile-first human handoff
PWA plus push notifications means your team picks up real conversations in 30 seconds, from anywhere, without opening a laptop. The speed of human escalation directly drives conversion.
Cost scales with usage, not with team size
No minimum contract, no annual seat fees, no upsell path. The economics of the plugin align with the economics of your business. You pay for conversations — that's it.
Full-context architecture, not RAG
Why we send the entire knowledge base to the model on every request — and why it changes the conversation.
What most tools do
RAG: retrieval-augmented generation
They chop your knowledge base into fragments, store them as vectors, and retrieve the closest match for each question. It's cheap. It also means the AI sees fragments, not connections.
What Zen Cortext does
Full-context: everything, every time
The entire knowledge base is sent to Claude in every request. The AI sees all your content at once — how your services relate to each other, which case studies are relevant to which industries, what pricing rules apply to what scenarios.
The trade-off is cost. Full-context is 5–10× more expensive per conversation than RAG. That's where the ~$1/conversation comes from. For basic FAQ scenarios, RAG is good enough. For consultative conversations where the AI needs to reason across your entire business — full-context is a different class of quality.
Pricing
No SaaS subscription. No seat fee. No minimum contract. You pay Anthropic directly for tokens through your own API key.
per conversation
A full conversation — typically 20–30 messages with complete business context — costs approximately one dollar. Run 1,000 conversations a month, pay around $1,000. Run 50, pay $50.
Budget control is straightforward: set daily and monthly spending caps in the Anthropic dashboard. When the cap is reached, the API stops responding. No surprises at the end of the month.

Who it's for — and who it's not for
We'd rather point you to the right tool than sell you the wrong one.
Built for
- WordPress sites with published content (pages, posts, case studies)
- Small and mid-size businesses spending on paid traffic
- Marketing agencies running campaigns for multiple clients
- Service businesses: consulting, legal, accounting, local services
- In-house marketing teams that can't justify $40K/year enterprise tools
Not built for
- Sites not on WordPress (Shopify, Webflow, Wix, custom platforms)
- Static brochure sites with no published content for the AI to learn from
- Businesses that need omnichannel — email, WhatsApp, SMS, Slack (Zen Cortext is web chat only, by design)
- Businesses that need outbound prospecting (this is inbound only)
- Enterprise teams requiring Salesforce-native integration, SSO, or SOC 2 compliance
This isn't a limitation we're hiding. It's a design choice. Zen Cortext does one thing — inbound conversations on your WordPress site — and does it at a quality level that enterprise tools charge 30× more for.
If you need omnichannel, look at Intercom Fin. If you need Salesforce-native, look at Qualified. If you need outbound, look at 11x.ai.
FAQ
The questions people actually ask before they sign up.
It automatically scans your WordPress content — every page, post, and case study. Each piece is classified, restructured, and added to the knowledge base. When you publish new content, the knowledge base updates automatically. For non-public information, use Knowledge Artifacts to add internal rules, pricing details, or unpublished case studies.
The AI only knows what you've published on your site plus what you've added through Knowledge Artifacts. If it doesn't have an answer, it says so and offers to connect the visitor with a human. This behavior is enforced in the system prompt, not just promised.
When the conversation gets serious, the AI sends a push notification to your team's phones through a Progressive Web App. The first person who taps the notification joins the conversation. The AI goes silent while the human talks. When the human disconnects, the AI resumes. If nobody is available, the AI collects contact information without revealing that no one picked up.
No. Zen Cortext creates a standalone chat page — not a widget in the corner of your site. You send traffic directly to this page. The visitor's full attention is on the conversation, not split between reading a landing page and typing in a small window.
All conversations, knowledge base content, and settings are stored in your WordPress database. No external cloud, no third-party service. Anthropic receives conversation content only at the moment of generating a response, through your own API key. The plugin developer has zero access to your data.
Yes. Channel adaptation rules let you configure different greetings, starter chips, and AI context based on UTM parameters, gclid, or referrer. One chat page URL behaves like dozens of campaign-specific landing pages. A visitor from your "SEO audit for law firms" campaign gets a conversation tuned to that exact topic.
Installation is the same as any WordPress plugin: upload, activate, enter your Anthropic API key. Configuration happens through an AI-guided setup — it asks questions about your business and builds the rules for you. No drag-and-drop editor, no complex config files. If you get stuck, ask for help right here in this chat.
Your costs scale with usage, and you control the ceiling through Anthropic's budget settings. Set a daily or monthly cap, and the API stops when you hit it. There's no overage billing and no surprise invoices.
