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.

Use Case

Create a technical brief

Briefing a developer or agency with "fix the SEO" leads to incomplete work because the scope is undefined. A structured audit changes that: specific gaps, specific fixes, specific snippets.

The problem

Without a defined spec, developers tend to address only the most visible issues. The less obvious gaps — missing schema.org, incorrect canonical, absent llms.txt, no robots.txt — stay broken because no one had a clear list of what to fix.

Writing a technical brief from scratch requires knowing what to check, how to check it, and how to prioritize the findings. Most founders and product managers do not have this domain knowledge.

How Existence Compiler helps

Analyze any URL — your own project, a competitor, or a reference site. The output becomes the brief: a structured audit that covers every dimension of digital existence, with severity ratings and ready-to-paste implementation snippets.

Export the Fix Pack — this is your technical brief

Hand the Fix Pack to your developer with the Executive Report for context

What the brief includes

Fix Pack contents

·Exact title tag and meta description to implement
·canonical link element with correct URL
·Open Graph og:title, og:description, og:image, og:url
·Twitter Card tags
·schema.org JSON-LD block (WebSite, WebApplication, or Organization)
·robots.txt content
·sitemap.xml structure
·llms.txt content for AI readability
·List of missing pages to create (/about, /privacy, /faq, etc.)

What this does not promise

The Fix Pack is an automatically generated starting point. All snippets should be reviewed before implementation. Copy suggestions in particular should be adapted to match the actual product voice and positioning.
