What is Existence Compiler?

It is an analysis system that takes your project URL and returns a Digital Existence Score plus an actionable report. It evaluates technical presence, semantic clarity, AI readability, trust signals, and distribution readiness.

What is the Digital Existence Score?

It is a score from 0 to 100 calculated by deterministic rules. It measures how detectable, understandable, and shareable your project is for search engines, AI agents, and social platforms.

Does it guarantee traffic, sales, or indexing?

No. Existence Compiler diagnoses technical and semantic gaps. Improving those conditions increases the likelihood of being discovered, but does not guarantee specific outcomes.

Which pages does it analyze?

In the current MVP it analyzes the main page of the URL you provide, plus checks for common pages such as /about, /pricing, /faq, /contact, /docs, /changelog, /security, /privacy, and /terms.

Yes. The Free plan is completely free and requires no account. You can analyze any URL and download the report in Markdown or JSON.

Does it store my data?

Existence Compiler stores minimal analysis metadata server-side to enable before/after comparisons, such as URL, score, timestamp and a compact report summary. Shared reports are stored with a 30-day TTL. It does not store raw HTML, full page text, raw schema dumps or unnecessary crawl payloads. No account is required for the free analysis flow.

Does it work with SPAs or React/Vue/Angular apps?

The analysis may be incomplete for JavaScript-rendered apps. The crawler fetches the initial HTML without executing JavaScript, so metadata injected only at runtime may not be detected.

It is a simple text file that helps AI systems understand what your project is and how to reference it. Existence Compiler generates a ready-to-use llms.txt snippet based on your detected content.

Does it use AI for analysis?

The main analysis is deterministic (rule-based). An optional AI enhancement layer can generate a deeper semantic summary if enabled, but the core report and score do not require it.

Example

Landing page metadata

A well-designed landing page with weak metadata is invisible on search and social. Here is what Existence Compiler produces for a landing page that is missing Open Graph, schema.org, and a proper meta description.

The scenario

Input

·Product: AI writing assistant for content teams
·Current title: "Home | WriteAI"
·Meta description: missing
·Open Graph: missing
·schema.org: missing
·Digital Existence Score: 22 / 100

Suggested output

Title tag

<title>WriteAI — AI Writing Assistant for Content Teams</title>

Meta description

<meta name="description" content="WriteAI helps content teams draft, edit,
and publish faster with AI. Structured workflows, brand voice controls,
and export to any CMS." />

Open Graph

<meta property="og:type" content="website" />
<meta property="og:url" content="https://writeai.app/" />
<meta property="og:title" content="WriteAI — AI Writing for Teams" />
<meta property="og:description" content="Draft, edit, and publish faster with AI." />
<meta property="og:image" content="https://writeai.app/og-image.png" />

schema.org JSON-LD

{
  "@context": "https://schema.org",
  "@type": "WebApplication",
  "name": "WriteAI",
  "url": "https://writeai.app",
  "description": "AI writing assistant for content teams.",
  "applicationCategory": "BusinessApplication",
  "operatingSystem": "Web"
}

Score after applying suggestions

Implementing the title, description, Open Graph, and schema.org suggestions typically moves the score from 22 to 58–65 / 100. The landing page becomes shareable on social platforms, correctly represented in search results, and readable by AI agents — without redesigning the page.

All copy suggestions should be reviewed and adapted to match the actual product positioning before implementation.
