What is the Sophyx AI Gateway?

The Sophyx AI Gateway is a machine-readable replica of your website, auto-generated by Sophyx and hosted at the customer's own subdomain (for example llms.yourbrand.com). It mirrors your live site into a clean Markdown (.md) version that LLMs can chunk and a semantic HTML (.html) version that crawlers can index, plus llms.txt, robots.txt, sitemap.xml, and JSON-LD structured data. AI engines like ChatGPT, Perplexity, Gemini, Claude, and Grok then have clear, structured, fresh, and connected information about the brand they can cite.

Why does my website even need a machine-readable replica?

Because buyers don't surf websites the way they used to. They ask AI agents instead. And AI agents don't render your UI. They don't see your hero animation, your gradient buttons, your component library, or your hover states. They only see raw text. If that text is buried in JavaScript or noisy markup, the model gives up and quotes a competitor that's easier to parse. The Sophyx replica engine solves that by mirroring your site into the formats AI was trained on: clean Markdown and semantic HTML.

What's actually inside the .md and .html replica?

Every page of your live site gets two parallel representations. The .md file is clean Markdown. Headings, lists, bolds, and short paragraphs the way LLMs chunk content for retrieval. The .html file is semantic, no-JS HTML with proper heading hierarchy, microdata, and JSON-LD embedded inline. Both are kept in sync with your real site and published together at llms.yourbrand.com.

Will my main website still matter?

Yes, for humans. Your real site keeps doing what it's great at: brand, design, conversion. The AI Gateway runs in parallel for AI agents. Two audiences, two surfaces, one brand. Your main domain ranks for human SEO. Your replica gets cited by AI engines.

Does the replica stay in sync when I update my real site?

Yes. The Sophyx replica engine watches your live site and your brand knowledge graph. When something changes (a new offer, a new proof point, a new product), the replica rebuilds, the .md and .html are regenerated, the JSON-LD is revalidated, and the edge cache flushes. No manual exports. No stale facts.

Why a subdomain instead of just publishing on my main site?

A dedicated subdomain like llms.yourbrand.com lets Sophyx own the AI-optimized replica end to end. Generation, edge hosting, JSON-LD validation, llms.txt freshness, all of it. Without ever touching your marketing site, CMS, or release process. It also gives AI crawlers a single, canonical, first-party surface to crawl, which improves citation rates.

How long until AI engines start citing me?

Most brands see their first AI citations within 14 days of going live, depending on how much public information already exists about them. Sophyx backs this with a 30-day visibility guarantee. If no AI engine names you in the first 30 days, you get refunded.

Does this hurt my main domain's SEO?

No. The AI Gateway lives on its own subdomain, with its own canonical URLs and its own sitemap. It does not duplicate or cannibalize your primary site. If anything, it improves brand-level signals across the open web that downstream SEO benefits from.

Do I have to write the content?

No. The replica engine pulls from your live site, your brand knowledge graph, and your existing positioning. Proof, customers, category, differentiators, all of it. You approve. Sophyx publishes. You can always edit, override, or regenerate in one click.

Why .md and .html, why both?

Different AI agents prefer different formats. Frontier LLMs (ChatGPT, Claude, Gemini, Perplexity, Grok) chunk and retrieve Markdown the most reliably. It is how their training data was structured. Crawlers like GPTBot, ClaudeBot, PerplexityBot, Googlebot, and Bingbot index HTML faster and with more structured metadata. Shipping both gets you the best of both pipelines, from one source.

How does the AI Gateway relate to AEO and GEO?

The AI Gateway is the surface where AEO (answer engine optimization) and GEO (generative engine optimization) actually live. AEO and GEO are the strategy. The AI Gateway is the deployable, hosted, machine-readable site that puts that strategy in front of AI engines. Sophyx ships both together. See the AEO and GEO playbook for the full method.

What if my industry isn't really in AI answers yet?

That is the cheapest moment to plant your AI Gateway. Brands that show up before AI engines have a strong default get cited disproportionately when buyers do start asking. Waiting is the most expensive move you can make.

What does setup actually look like?

About five minutes inside Sophyx. You enter your subdomain, copy two CNAME records into your DNS provider, and click Verify. SSL is provisioned automatically. Once the domain is active you click Generate and Sophyx publishes the site to the edge.

Can I bring my own domain or only subdomains?

Subdomains today (for example llms.yourbrand.com or ai.yourbrand.com). This keeps your AI Gateway cleanly separated from your marketing site while still being first-party at your brand. Apex and root-domain support is on the roadmap.

The brutal reality

Buyers stopped surfing. They're asking AI.

Less browsing. Less scrolling. Less time on your beautiful site. Your UI doesn't matter to an AI agent. Your content does. If your site isn't machine-readable, you're invisible in the moment the buying decision is made.

ChatGPT

Asking

How do I fix my hair?

SearchThinkDeep research

Real buyer queries, every second, on every AI engine.

AI doesn't see your UI.
Your hero animation, your gradient buttons, your component library. None of it ships to ChatGPT. The model only sees raw text. If that text is buried in JS, AI quotes someone else.
Your name isn't in the answer.
Buyers ask AI to compare tools in your category. AI lists 5 brands. You're not one of them. Not because you're worse. Because your site reads like noise to an LLM.
Every week is pipeline you'll never see.
There is no "page 2" in AI search. No SERP. No referrer headers. Just silence, and a competitor's logo where yours should be.

Cost of doing nothing

Every day you wait, AI engines learn your competitors better. The gap is compounding.

The whole story, in one paragraph

Buyers don't surf websites anymore. They ask ChatGPT, Perplexity, Gemini, Claude, and Grok. And AI agents don't see your gradients, your animations, or your hero video. They read text. Sophyx's replica engine mirrors your live site into a clean .md and .html replica at llms.yourbrand.com . Purpose-built for AI agents to read, parse, and cite you.

The Sophyx replica engine

Your website was built for humans. AI agents have no eyes.

Buyers don't surf websites anymore. They ask AI. And AI doesn't render your hero animation, your gradient buttons, or your component library. All it sees is text that's clean enough to parse. So Sophyx invented a replica engine. It mirrors your live site into a parallel .md + .html version at llms.yourbrand.com. Zero UI. Every fact tagged. Purpose-built for AI agents to read and cite.

01
AI agents are the new browser.
ChatGPT, Perplexity, Gemini, Claude, and Grok now answer questions buyers used to type into Google. They don't open tabs. They consume text.
02
UI doesn't ship to AI.
Your beautiful site doesn't get rendered by an LLM. The model sees raw markup. If that markup is noisy, it gives up and quotes someone else.
03
The replica is the fix.
Sophyx ships every page as both a clean .md (great for LLM chunking) and a semantic .html (great for crawlers), backed by JSON-LD facts.

.md

Markdown replica

Every page is mirrored as clean Markdown. Headings, bullets, bolds, and short paragraphs the way LLMs chunk content. No nav clutter. No tracking pixels. Just the facts about your brand in the format AI engines were trained to read. Paired with a Sophyx-generated llms.txt so crawlers know where to look.

.html

Semantic HTML replica

The same content rendered as no-JS, accessible HTML with proper headings, microdata, and JSON-LD from the Sophyx schema builder embedded inline. Crawl governed by a Sophyx-curated robots.txt. Indexable by Google and Bing the moment they crawl it, and still ridiculously clean for AI agents.

Q: What is the Sophyx replica engine?

A: The Sophyx replica engine is a system that takes a brand's live human-facing website and renders a parallel, machine-readable version of it, published as Markdown (.md) and semantic HTML (.html) at a Sophyx-hosted subdomain like llms.yourbrand.com. The replica strips visual chrome and keeps the facts AI agents need to cite the brand correctly: positioning, proof, category, differentiators, products, FAQs, and structured JSON-LD. It is the deployable layer of Sophyx's broader AEO and GEO playbook, and it stays in sync with the human site automatically.

From signed CNAME to AI citation

Three steps. Fourteen days.

You connect the domain. The replica engine builds the machine-readable mirror. AI agents start citing you. That's the whole flow.

01
Connect your subdomain
~ 5 minutes
Add a subdomain like llms.yourbrand.com inside Sophyx, copy two DNS records, paste them at your DNS provider. Sophyx validates and provisions SSL on its edge automatically.
No DevOps. No code. No 'wait for IT.'
02
The replica engine runs
Automatic. In your sleep.
Sophyx mirrors every page of your live site into clean .md (for LLM chunking) and semantic .html (for crawlers), plus llms.txt, robots.txt, sitemap.xml, and JSON-LD. Every page is built so AI agents can read, parse, and cite it without guessing.
You write nothing. The replica engine does the work.
03
AI engines start citing you
First citations in ~ 14 days
ChatGPT, Perplexity, Gemini, Claude, and Grok crawl your gateway, ingest clean and structured information, and begin naming you in answers about your category.
You go from invisible → cited. Measurably.

Q: How long until AI engines actually cite my brand?

A: Most brands see their first citations within 14 days of the Sophyx AI Gateway going live. The replica engine ships a clean Markdown and semantic HTML version of your site to llms.yourbrand.com, then AI crawlers like GPTBot, ClaudeBot, PerplexityBot, Googlebot, and Bingbot pick it up and index it. If no AI engine names your brand inside 30 days, Sophyx refunds you under its visibility guarantee.
