Every website has a discovery gap…

Businesses invest in SEO to attract website visitors. But most visitors leave without the business knowing what they wanted, what they found, or why they left. This has been the case since the first website was launched over 30 years ago.

AI is widening that gap. Customers increasingly rely on AI agents to find information and make recommendations—often without visiting the business’s website at all.

CRSTBL closes the discovery gap with two connected systems:

CRSTA guides the people who visit your website.

Cumae gives AI agents accurate, business-authorized information to discover and use.

Start to close the gap today.

The AEO Landscape

What We Know vs. What We Don't

SEO → AEO Migration

We know SEO is migrating to AEO.

We don't know the speed or scale of migration.

This leaves businesses uncertain about which processes to change and which technology to invest in.

Start by organizing the foundational business information every LLM will need to query—now and in the future. Website content served via RAG won't scale as AEO traffic grows. Cumae helps businesses structure this information block by block, creating a durable source of truth regardless of how AI protocols evolve.

Intent Masking

We know users prompt LLMs with widely varying phrasing.

We don't know how well the LLM interprets user intent, or how many prompts it receives.

Businesses can't be sure they're delivering the information visitors actually need.

CRSTA and Cumae capture inbound and outbound conversation transcripts and analyze how effectively your information answers visitor questions. Our telemetry system tracks what was answered, what wasn't, and what data is missing—so businesses can close gaps and improve response rates over time.

Source of Truth

We know LLMs gather information across the internet to formulate responses.

We don't know which sources they use or how much weight each receives.

This creates a source-of-truth problem that harms both the LLM's accuracy and the business's reputation.

Cumae requires LLMs to register with CRSTBL before accessing a business's source-of-truth data via MCP. This lets businesses track who is requesting their information, what they're requesting, how often, and whether the request was fulfilled. We believe registered access will become standard as knowledge sharing grows more complex and private networks require verification.

AI Search Rankings

We know many companies are trying to figure out how to appear in AI search results.

We don't know what drives those rankings, or how often LLM algorithms change.

A ground-zero problem: we can observe the "what" but not yet the "why" or "how."

We partner with companies and researchers working on this problem where their work intersects with ours. CRSTBL focuses on the intent-to-decision layer of AEO discovery; predicting how LLMs select sources is outside our scope, but improving what they find when they arrive is squarely within it.

AI-Driven Decisions

We know AI will eventually dominate the search landscape.

We don't know how much consumers will delegate decision-making to AI.

Building a decision model that reliably connects AI agent recommendations to the right businesses is an open challenge.

We're developing a system of linked concepts that interlaces subject-intent-result chains to mimic human decision flows. Still early-stage, it will be refined with conversation and telemetry data over time. We believe this approach will form the basis of highly relevant AEO results and AI-guided conversations.

Distributed Access

We know many businesses will run their own LLMs, and thousands of agents will query business partners and competitors.

We don't know what system will serve as the directory or permission layer for this traffic.

A blindspot: how to regulate inbound information requests while keeping legitimate access fast.

We anticipate millions of individual language models serving businesses and consumers. An agentic system handling critical business information must be distributed to scale. CRSTA is designed to run on remote LLM servers (with permission) and route prompts efficiently across vast information networks.

The AEO Discovery Loop

Every conversation makes the next one smarter.

AI search is fragmenting across LLMs, voice assistants, and social platforms. CRSTBL treats them as one loop: capture intent wherever the customer arrives, answer in real conversation, save every context, then publish it back so every engine finds you next time.

1 · Discovery
Customers now start with LLMs, voice, and social — not just Google. CRSTBL recognizes intent across the full funnel and meets the visitor wherever the conversation begins.
4 · Publish
Every context is published in the formats each engine reads — structured web pages, AI-ready business pages, and Cumae outputs — so the loop repeats wherever your customers search next.
CRSTBL AEO Discovery Loop DISCOVERY ANSWERS CONTEXTS PUBLISH
2 · Answers
CRSTA answers in real conversation, not scripted flows. Website, business page, kiosk, or trade‑show booth — the same agent, tuned to your products, services, and policies.
3 · Contexts
Every conversation becomes a labeled context. Over time this forms your business’s institutional knowledge — a proprietary asset your team, your agent, and AI engines can all learn from.

Cumae Records

And this is what an AI agent reads.

A website tells a person what a hotel looks like. A Cumae record tells an AI agent the identity, the inventory, the third-party accolades and the exact parameters it needs to request a booking — as structured, addressable blocks rather than pages to interpret.

Casa CoCoMo Cumae discovery record v1.0 · hospitality / resort · revision r-0051 · 19 blocks · 7 formats on /ai
A Cumae discovery record for Casa CoCoMo, showing the document record header with UUID, revision, block count and feed state, above three blocks: Company Information with identity, location, websites, phone numbers and inventory; Accolades and Third-Party Ratings with eight independent listings; and Reservations Booking Construct showing a human booking path and an agent-directed A2A path with quote and hold endpoints and eleven typed request parameters.
Addressable blocksEvery block carries its own UUID, source and freshness stamp — retrievable on its own, not buried in a page.
Typed request parametersAn agent reads ISO 8601, required and enum, 9 values — it does not guess what a booking form wants.
Declared boundaries“No third-party OTA surfaces published here.” The record states what it does not cover.

Casa CoCoMo and Copperline Sandwich Co. are fictitious businesses created by CRSTBL to demonstrate the Cumae file structure. Addresses, phone numbers, prices, personnel and all third-party ratings shown are invented for illustration; no rating shown has been issued and no affiliation is implied. The structure and depth are real.

CRSTA and Cumae work independently.

Your business information in the AI discovery layer

AI is already talking about your business. But it may not be getting the truth from you.

Cumae helps your business publish an authoritative record, monitor material AI representations against it, and control access for registered applications and approved business partners.

01 — Publish

Establish a business-controlled record.

Your company name, canonical website, locations, offerings and a path to current authoritative information — then the deeper record behind it.

02 — Monitor

Compare AI answers to your record.

Test a defined library of material business questions across designated AI services and document material inaccuracies with evidence.

03 — Govern

Decide who gets to see what.

Give registered applications, individually approved partners and your own agents different levels of access to your information.

See a live Cumae record

Depth a web menu was never built to carry.

A menu tells a person what a sandwich costs. A Cumae record tells an AI agent what is in it, what it weighs, which allergens are present, which are absent — and which are absent but still at cross-contact risk. That third state is what a customer with a serious allergy is actually asking about.

“Each item is declared in one of three states — present, not present, or not present but at cross-contact risk from shared equipment. That third state is the one most menus omit.”
Verbatim, from a live Cumae record

What “control” means here: you control the information your business publishes and the access policies you configure. CRSTBL does not control third-party AI platforms and cannot guarantee how any of them answer. Monitoring applies to defined questions and designated AI services.

The AI AEO/GEO Discovery Loop

One Platform. Live Conversations. Continuous AI Discovery.

Your business information becomes both the engine that answers customers today and the signal that keeps AI models current on your brand tomorrow — through a review-and-republish loop, not a black box.

1

Your Data On the CRSTBL Platform.

Menus, products, services, hours, locations, and sales knowledge flow into CRSTBL — where they immediately power live AI conversations with visitors and customers.

Menus Catalogs Locations Docs
2

Published to LLMs via Open Standards.

CRSTBL transforms your business information into an LLM-digestible structure and publishes it to subscribed AI platforms through open AEO/GEO standards — so ChatGPT, Perplexity, and others can answer accurately about your business.

AEO GEO Open Standards
3

Reviewed Refresh from Real Conversations.

Live conversations surface where your Cumae profile has gaps — missing product details, new customer questions, outdated hours. You (or CRSTBL, on managed plans) review the flagged updates, and the refreshed AEO/GEO file republishes to subscribed LLMs on their next pull.

Gaps Flagged Human Review Republish

It’s a loop. Every conversation exposes another gap Cumae can close — then you approve the update, and your AI Discovery footprint gets stronger with each cycle.

Fast Launch — Minimum IT

From Sign-Up to Go-Live — Days for Business, Weeks for Enterprise.

Business accounts launch in a day using guided setup. Enterprise networks follow a structured 4–8 week rollout with a dedicated onboarding manager. Both paths skip the traditional software project.

Step Description CRSTA Business CRSTA Enterprise
1 Create Account 1 Day < 3 Days
2 Business Info Validation 1 Day < 5 Days
3 Data and Info 1 Day 1–2 Weeks
4 Conversation Context 1 Day 2–3 Weeks
5 Test Agent Conversations 1 Day 1 Week
6 Go-Live and Deploy to Website 1 Day Custom window

Enterprise timelines are estimates for a typical multi-location rollout with a dedicated onboarding manager. Complex deployments (large catalogs, avatar builds, integrations) can extend the window; simpler deployments compress it.

Frequently Asked

Common questions about CRSTBL.

Fast answers to the questions we hear most. Each links out to a deeper explainer in the Knowledge Center.

What does CRSTBL stand for?

CRSTBL is pronounced “Crystal Ball.” The name reflects the platform’s goal — helping businesses see what customers actually want through conversation. Traditional analytics tells you what customers did; conversations reveal why. Full story: What is CRSTA?

What is CRSTA?

CRSTA is the AI conversation agent behind every CRSTBL deployment. It reads customer questions in natural language, answers from your real business information, and labels every exchange as a stored context. Full explainer: What is CRSTA?

What is Cumae?

Cumae — pronounced “Cue-Me” — turns your business information into one authoritative profile that registered AI applications read directly. When a customer asks ChatGPT, Perplexity, Claude, or Gemini about your business, Cumae is the source those systems draw from, so they describe you the way you describe yourself. Full explainer: What is Cumae?

What’s the difference between Cumae and CRSTA?

Cumae publishes and governs the authoritative business information used in AI discovery. CRSTA applies that knowledge in conversations with your customers. They serve different functions and can be used separately or together. Full explainers: What is Cumae? and What is CRSTA?

What is conversational discovery?

Helping customers find products, services, or answers through natural conversation instead of menus, search bars, or navigation trees — browsing replaced with dialogue. Full reference: What is Conversational Discovery?

How is CRSTBL different from ChatGPT?

General-purpose AI tools answer from what they were trained on. CRSTBL answers from your business information — the menu, catalog, or service descriptions you provide — and won’t invent things you didn’t give it. Full comparison: CRSTBL vs Traditional Chatbots.

I already have a Google Business Profile. Do I still need Cumae?

Google Business Profile gets you into Google Maps and Search, but the AI ecosystem is much bigger than Google — and networks like Uber Eats, DoorDash, and Apple, along with independent LLMs, have little reason to use Google’s directory. Cumae is neutral, and it keeps one source current instead of updating Google, Yelp, Facebook, and every delivery app separately. It complements your GBP listing rather than replacing it. Full explainer: What is Cumae?

Does CRSTBL replace customer service staff?

No. CRSTBL handles routine, repetitive, and discovery-style conversations so staff can focus on the ones that need judgment, negotiation, or relationship-building. The goal is reducing repetitive work and improving customer responsiveness.

Why are conversations valuable for businesses?

Conversations reveal what customers actually want. Traditional analytics shows page views, clicks, and traffic sources; conversations show questions, objections, preferences, and buying intent. Full explainer: What is Customer Intent?
